Phonemic diversity
The recent studies of phonemic diversity as evidence of human migration history aren't worth the paper they are printed on, as any historical linguist would tell you. They are published by non-linguists who don't understand what phonemes are or how language change works, but merely assume that it is the same as genetic change. However phonemes are theoretical abstractions and depend on the interpretation of a linguist and the particular theopretical framework she uses - so a single language may be analyzed as having 25 phonemes or 85 depending on the chosen analysis (for example; several languages in Mesoamerica have this type of analytical questions). Second phonemes are not necessarily inherited but are frequently laterally transmitted between populations leaving no trace behind of the original configuration (unlike genes). Linguists like Levinson, Evans, Bowern and many others have refuted these bogus studies but so-called scientists refuse to listen to actual experts in the area they are studying and keep publishing new just-so stories like the recent Perreault and Mathews paper and Atkinsons earlier paper making the same claims. This article should not describe those studies as presenting fact, because they don't. ·ʍaunus·snunɐw· 22:26, 18 August 2012 (UTC)


 * Somewhere along the path from apes to humans, the addition of a new gene to the genome allowed a transiently activatable surface on the pharyngeal wall to form speech sounds. There is a place for each voiced sound, all together they form the pronunciation nest of a particular language. Voiceless consonants make words easier to understand and increase their number. It was now possible to put an idea into the combination of sounds that the whole human herd understood in the same way.
 * The monkey's pharyngeal wall has no activatable surface. The shortest: The dumb person and the monkey do not speak because they have no speech sounds.
 * Leonhard Klaar 212.53.117.118 (talk) 01:16, 26 July 2022 (UTC)
 * Actually, a chimp can produce a wide enough range of sounds that it would have all the phonemes it needed to speak, if only it had the cognative abilities. It wouldn't sound like a human language, it wouldn't be English, but there are enough speech sounds to let it be as complex as English. It's a mistake to think that speech presupposes the full evolution of the speech organs. Rather, the reverse is true: the way evolution works requires that people began to speak first, and the evolutionary advantages that speech brought would then drive the optimization of the speech organs.

Merger proposal
I propose merging this article with Origin of Language. The merged article should probably be here, though I don't have strong feelings about that. In principle, "language" and "speech" are not necessarily the same thing, and both pages could be kept if a distinction is being made. But at present I don't see any such distinction, and if one is intended it is certainly not explained. It seems that both of them cover much the same ground. Doric Loon (talk) 17:21, 26 October 2022 (UTC)


 * ok 173.18.124.148 (talk) 03:48, 1 November 2022 (UTC)
 * Disagree topics are similar but independently notable and it would be I think confusing to have them together. Distinction is better made I think by improving the articles. Tom (LT) (talk) 06:14, 6 November 2022 (UTC)
 * Hi @Tom (LT), it would be helpful if you could say what distinction is being made (or what distinction you think should be made). At present the two articles seem to me to address an identical set of questions. Doric Loon (talk) 17:34, 6 November 2022 (UTC)
 * Oppose - The origin of language article is about the literal origin of language, its relationship with human evolution, and its consequences, while the origin of speech article is about the physiological development of the human speech organs. Treetoes023 (talk) 05:40, 11 November 2022 (UTC)
 * Hi @Treetoes023, that's not what the opening sentence of this article says, but if you want to change the opening of both articles to make that distinction clear, I would withdraw the merge proposal. Doric Loon (talk) 07:38, 11 November 2022 (UTC)
 * But then other changes would have to follow. If I understand Treetoes023 correctly, then the whole of sections 5 and 6 would have to be deleted from this article and worked into the other one. Is there a consensus for that? Doric Loon (talk) 11:43, 11 November 2022 (UTC)
 * Support per WP:OVERLAP – I changed my mind from opposing the merge to supporting the merge. After reading Doric Loon's comments I decide to read the entirety of both articles instead of just skimming and I've come to the conclusion that it would be a better fit if the pages where just one as the origin of speech is a subtopic of the origin of language and is not different enough to have its own dedicated article along with the fact that the origin of speech article says a lot of the same things that the origin of language article does. Treetoes023 (talk) 17:23, 11 November 2022 (UTC)
 * Comment. If we do merge these, I think origin of language is the more general topic and therefore the better merge target. For example, according to one major theory, language evolved independently of speech. –&#8239;Joe (talk) 09:17, 3 December 2022 (UTC)
 * I agree, if the articles are merged "Origin of speech" should be merged into "Origin of language" because it is the more general topic, not the other way around. Treetoes023 (talk) 17:03, 8 December 2022 (UTC)
 * Support per @Treetoes023 and agree that it should be merged into Origin of language. Irecorsan (talk) 10:06, 15 March 2023 (UTC)
 * Comment – Hey, this merge discussion is open for almost a year. Be bold and please either merge it or close the stale merge proposal. Pinging, , , , . Artem.G (talk) 19:52, 24 July 2023 (UTC)
 * I agree, I left a message on Doric Loon's talk page about it a month ago, but he never responded. – Treetoes023 (talk) 20:42, 24 July 2023 (UTC)
 * Hi @Artem.G, sorry for not having responded. I'm in a stressful phase, so I've not had much time for Wikipedia. I do think this merge should go ahead now, but I fear it may be quite a big job. But yes, let's do it. Doric Loon (talk) 13:42, 25 July 2023 (UTC)
 * Oppose on the grounds that both articles are already too long (each alone are over the 100k at which a split is usually warranted), so merge is implausible. Thus it's best to split the content between the two articles (or probably more); so, restructure rather than merge. Speech focussing just on the physiological development of the human speech organs, and the language article contain the rest might be one way of doing so. Klbrain (talk) 22:17, 29 July 2023 (UTC)
 * STRENUOUSLY Oppose (5th comment ever, 1st since 2016. Please be gentle re: Wiki folkways.) I'm an academic linguist and a researcher in this topic, just stumbled on this article and am horrified.  Doric Loon's suggestion only makes sense at all because this article is so clogged with material that belongs not here, but in Origin of Language, if at all.  The articles on Language and Speech have their own problems, but they succeed in making clear the distinction made in every intro to linguistics class between language as carrying meaning and speech as getting language out of one person's mouth and into another's ear.  This article fails entirely to maintain that distinction.  An account of how both production and perception of vocal language evolved is a vigorous and current research topic, and is the proper subject of this article, which needs radical surgery, but not suppression by merger.
 * I won't have the time for at least a year to figure out editing and Wikipedia practices enough to fix this (and maybe Speech) myself, so could somebody start by lopping off the "Speculative Scenarios" and "Conceptual Frameworks" parts? They have nothing at all to do with vocal speech as such, so that would be a start. Thanks. Frphnflng (talk) 22:06, 1 September 2023 (UTC)
 * Hi @Frphnflng, I quite agree with you about the distinction that could be made. Trouble is, the two articles at present are not making it. I thought a merge was the simplest solution, and I think it would work since language and speech evolved in parallel, but a two-article solution would work too, if we are strict about what belongs where.
 * At this point I should probably withdaraw the merge proposal, since I also am struggling to find enough Wikipedia time to tackle this very big topic, and there clearly is not a consensus. But I wonder, Frphnflng, since you have researched in the field, if you could be persuaded to re-write the head of both articles, even if you can't do more than that.
 * Meantime, I am going to delete those two sections that you mentioned. Those were indeed the sections that first made me unhappy with this article. In case there is good material there that should be used elsewhere, I will copy the sections in here, in a foldaway box.
 * ==Speculative scenarios==
 * ===Early speculations===
 * In 1861, historical linguist Max Müller published a list of speculative theories concerning the origins of spoken language: These theories have been grouped under the category named invention hypotheses. These hypotheses were all meant to understand how the first language could have developed and postulate that human mimicry of natural sounds were how the first words with meaning were derived.
 * Bow-wow. The bow-wow or cuckoo theory, which Müller attributed to the German philosopher Johann Gottfried Herder, saw early words as imitations of the cries of beasts and birds. This theory, believed to be derived from onomatopoeia, relates the meaning of the sound to the actual sound formulated by the speaker.
 * Pooh-pooh. The Pooh-Pooh theory saw the first words as emotional interjections and exclamations triggered by pain, pleasure, surprise and so on. These sounds were all produced on sudden intakes of breath, which is unlike any other language. Unlike emotional reactions, spoken language is produced on the exhale, so the sounds contained in this form of communication are unlike those used in normal speech production, which makes this theory a less plausible one for language acquisition.
 * Ding-dong. Müller suggested what he called the Ding-Dong theory, which states that all things have a vibrating natural resonance, echoed somehow by man in his earliest words. Words are derived from the sound associated with their meaning; for example, “crash became a word for thunder, boom for explosion.” This theory also heavily relies on the concept of onomatopoeia.
 * Yo-he-ho. The yo-he-ho theory saw language emerging out of collective rhythmic labor, the attempt to synchronize muscular effort resulting in sounds such as heave alternating with sounds such as ho. Believed to be derived from the basis of human collaborative efforts, this theory states that humans needed words, which might have started off as chanting, to communicate. This need could have been to ward off predators, or served as a unifying battle cry.
 * Ta-ta. This did not feature in Max Müller's list, having been proposed in 1930 by Sir Richard Paget. According to the ta-ta theory, humans made the earliest words by tongue movements that mimicked manual gestures, rendering them audible.
 * A common concept of onomatopoeia as the first source of words is present; however, there is a problem with this theory. Onomatopoeia can explain the first couple of words all derived from natural phenomenon, but there is no explanation as to how more complex words without a natural counterpart came to be. Most scholars today consider all such theories not so much wrong – they occasionally offer peripheral insights – as drastically limited. These theories are too narrowly mechanistic to comprehensively explain the origin of language. They assume that once the ancestors of humans had stumbled upon the appropriate ingenious mechanism for linking sounds with meanings, language automatically evolved and changed.
 * ===Problems of reliability and deception===
 * From the perspective of modern science, the main obstacle to the evolution of speech-like communication in nature is not a mechanistic one. Rather, it is that symbols – arbitrary associations of sounds with corresponding meanings – are unreliable and may well be false. As the saying goes, "words are cheap". The problem of reliability was not recognised at all by Darwin, Müller or the other early evolutionist theorists.
 * Animal vocal signals are for the most part intrinsically reliable. When a cat purrs, the signal constitutes direct evidence of the animal's contented state. One can "trust" the signal not because the cat is inclined to be honest, but because it just can't fake that sound. Primate vocal calls may be slightly more manipulable, but they remain reliable for the same reason – because they are hard to fake. Primate social intelligence is Machiavellian – self-serving and unconstrained by moral scruples. Monkeys and apes often attempt to deceive one another, whilst at the same time remaining constantly on guard against falling victim to deception themselves. Paradoxically, it is precisely primates' resistance to deception that blocks the evolution of their vocal communication systems along language-like lines. Language is ruled out because the best way to guard against being deceived is to ignore all signals except those that are instantly verifiable. Words automatically fail this test.
 * Words are easy to fake. Should they turn out to be lies, listeners will adapt by ignoring them in favour of hard-to-fake indices or cues. For language to work, then, listeners must be confident that those with whom they are on speaking terms are generally likely to be honest. A peculiar feature of language is "displaced reference", which means reference to topics outside the currently perceptible situation. This property prevents utterances from being corroborated in the immediate "here" and "now". For this reason, language presupposes relatively high levels of mutual trust in order to become established over time as an evolutionarily stable strategy. A theory of the origins of language must, therefore, explain why humans could begin trusting cheap signals in ways that other animals apparently cannot (see signalling theory).
 * ==== "Kin selection" ====
 * The "mother tongues" hypothesis was proposed in 2004 as a possible solution to this problem. W. Tecumseh Fitch suggested that the Darwinian principle of "kin selection" – the convergence of genetic interests between relatives – might be part of the answer. Fitch suggests that spoken languages were originally "mother tongues". If speech evolved initially for communication between mothers and their own biological offspring, extending later to include adult relatives as well, the interests of speakers and listeners would have tended to coincide. Fitch argues that shared genetic interests would have led to sufficient trust and cooperation for intrinsically unreliable vocal signals – spoken words – to become accepted as trustworthy and so begin evolving for the first time.
 * =====Criticism=====
 * Critics of this theory point out that kin selection is not unique to humans. Ape mothers also share genes with their offspring, as do all animals, so why is it only humans who speak? Furthermore, it is difficult to believe that early humans restricted linguistic communication to genetic kin: the incest taboo must have forced men and women to interact and communicate with non-kin. The extension of the posited "mother tongue" networks from relatives to non-relatives remains unexplained.
 * ==== "Reciprocal altruism" ====
 * Ib Ulbæk invokes another standard Darwinian principle – "reciprocal altruism" – to explain the unusually high levels of intentional honesty necessary for language to evolve. 'Reciprocal altruism' can be expressed as the principle that if you scratch my back, I'll scratch yours. In linguistic terms, it would mean that if you speak truthfully to me, I'll speak truthfully to you. Ordinary Darwinian reciprocal altruism, Ulbæk points out, is a relationship established between frequently interacting individuals. For language to prevail across an entire community, however, the necessary reciprocity would have needed to be enforced universally instead of being left to individual choice. Ulbæk concludes that for language to evolve, early society as a whole must have been subject to moral regulation.
 * =====Criticism=====
 * Critics point out that this theory fails to explain when, how, why or by whom "obligatory reciprocal altruism" could possibly have been enforced. Various proposals have been offered to remedy this defect. A further criticism is that language doesn't work on the basis of reciprocal altruism anyway. Humans in conversational groups don't withhold information to all except listeners likely to offer valuable information in return. On the contrary, they seem to want to advertise to the world their access to socially relevant information, broadcasting it to anyone who will listen without thought of return.
 * ==== "Gossip and grooming" ====
 * Gossip, according to Robin Dunbar, does for group-living humans what manual grooming does for other primates – it allows individuals to service their relationships and so maintain their alliances. As humans began living in larger and larger social groups, the task of manually grooming all one's friends and acquaintances became so time-consuming as to be unaffordable. In response to this problem, humans invented "a cheap and ultra-efficient form of grooming" – vocal grooming. To keep your allies happy, you now needed only to "groom" them with low-cost vocal sounds, servicing multiple allies simultaneously whilst keeping both hands free for other tasks. Vocal grooming (the production of pleasing sounds lacking syntax or combinatorial semantics) then evolved somehow into syntactical speech.
 * =====Criticism=====
 * Critics of this theory point out that the very efficiency of "vocal grooming" – that words are so cheap – would have undermined its capacity to signal commitment of the kind conveyed by time-consuming and costly manual grooming. A further criticism is that the theory does nothing to explain the crucial transition from vocal grooming – the production of pleasing but meaningless sounds – to the cognitive complexities of syntactical speech.
 * ====From pantomime to speech====
 * According to another school of thought, language evolved from mimesis – the "acting out" of scenarios using vocal and gestural pantomime. Charles Darwin, who himself was skeptical, hypothesised that human speech and language is derived from gestures and mouth pantomime. This theory, further elaborated on by various authors, postulates that the genus Homo, different from our ape ancestors, evolved a new type of cognition. Apes are capable of associational learning. They can tie a sensory cue to a motor response often trained through classical conditioning. However, in apes,  the conditioned sensory cue is necessary for a conditioned response to be observed again. The motor response will not occur without an external cue from an outside agent. A remarkable ability that humans possess is the ability to voluntarily retrieve memories without the need for a cue (e.g. conditioned stimulus). This is not an ability that has been observed in animals except language-trained apes. There is still much controversy on whether pantomime is a capability for apes, both wild and captured. For as long as utterances needed to be emotionally expressive and convincing, it was not possible to complete the transition to purely conventional signs.  On this assumption, pre-linguistic gestures and vocalisations would have been required not just to disambiguate intended meanings, but also to inspire confidence in their intrinsic reliability. If contractual commitments were necessary in order to inspire community-wide trust in communicative intentions, it would follow that these had to be in place before humans could shift at last to an ultra-efficient, high-speed – digital as opposed to analog – signalling format. Vocal distinctive features (sound contrasts) are ideal for this purpose. It is therefore suggested that the establishment of contractual understandings enabled the decisive transition from mimetic gesture to fully conventionalised, digitally encoded speech.
 * ==== "Ritual/speech coevolution" ====
 * The ritual/speech coevolution theory was originally proposed by the distinguished social anthropologist Roy Rappaport before being elaborated by anthropologists such as Chris Knight, Jerome Lewis, Nick Enfield, Camilla Power and Ian Watts. Cognitive scientist and robotics engineer Luc Steels is another prominent supporter of this general approach, as is biological anthropologist/neuroscientist Terrence Deacon.
 * These scholars argue that there can be no such thing as a "theory of the origins of language". This is because language is not a separate adaptation but an internal aspect of something much wider – namely, human symbolic culture as a whole. Attempts to explain language independently of this wider context have spectacularly failed, say these scientists, because they are addressing a problem with no solution. Can we imagine a historian attempting to explain the emergence of credit cards independently of the wider system of which they are a part? Using a credit card makes sense only if you have a bank account institutionally recognised within a certain kind of advanced capitalist society – one where communications technology has already been invented and fraud can be detected and prevented. In much the same way, language would not work outside a specific array of social mechanisms and institutions. For example, it would not work for an ape communicating with other apes in the wild. Not even the cleverest ape could make language work under such conditions.
 * Advocates of this school of thought point out that words are cheap. As digital hallucinations, they are intrinsically unreliable. Should an especially clever ape, or even a group of articulate apes, try to use words in the wild, they would carry no conviction. The primate vocalizations that do carry conviction – those they actually use – are unlike words, in that they are emotionally expressive, intrinsically meaningful and reliable because they are relatively costly and hard to fake.
 * Speech consists of digital contrasts whose cost is essentially zero. As pure social conventions, signals of this kind cannot evolve in a Darwinian social world – they are a theoretical impossibility. Being intrinsically unreliable, language works only if you can build up a reputation for trustworthiness within a certain kind of society – namely, one where symbolic cultural facts (sometimes called "institutional facts") can be established and maintained through collective social endorsement. In any hunter-gatherer society, the basic mechanism for establishing trust in symbolic cultural facts is collective ritual. Therefore, the task facing researchers into the origins of language is more multidisciplinary than is usually supposed. It involves addressing the evolutionary emergence of human symbolic culture as a whole, with language an important but subsidiary component.
 * =====Criticism=====
 * Critics of the theory include Noam Chomsky, who terms it the "non-existence" hypothesis – a denial of the very existence of language as an object of study for natural science. Chomsky's own theory is that language emerged in an instant and in perfect form, prompting his critics in turn to retort that only something that doesn't exist – a theoretical construct or convenient scientific fiction – could possibly emerge in such a miraculous way. The controversy remains unresolved.
 * ===Twentieth century speculations===
 * ====Festal origins====
 * The essay "The festal origin of human speech", though published in the late nineteenth century, made little impact until the American philosopher Susanne Langer re-discovered and publicised it in 1941.
 * The theory sets out from the observation that primate vocal sounds are above all emotionally expressive. The emotions aroused are socially contagious. Because of this, an extended bout of screams, hoots or barks will tend to express not just the feelings of this or that individual but the mutually contagious ups and downs of everyone within earshot.
 * Turning to the ancestors of Homo sapiens, the "festal origin" theory suggests that in the "play-excitement" preceding or following a communal hunt or other group activity, everyone might have combined their voices in a comparable way, emphasizing their mood of togetherness with such noises as rhythmic drumming and hand-clapping. Variably pitched voices would have formed conventional patterns, such that choral singing became an integral part of communal celebration.
 * Although this was not yet speech, according to Langer, it developed the vocal capacities from which speech would later derive. There would be conventional modes of ululating, clapping or dancing appropriate to different festive occasions, each so intimately associated with that kind of occasion that it would tend to collectively uphold and embody the concept of it. Anyone hearing a snatch of sound from such a song would recall the associated occasion and mood. A melodic, rhythmic sequence of syllables conventionally associated with a certain type of celebration would become, in effect, its vocal mark. On that basis, certain familiar sound sequences would become "symbolic".
 * In support of all this, Langer cites ethnographic reports of tribal songs consisting entirely of "rhythmic nonsense syllables". She concedes that an English equivalent such as "hey-nonny-nonny", although perhaps suggestive of certain feelings or ideas, is neither noun, verb, adjective, nor any other syntactical part of speech. So long as articulate sound served only in the capacity of "hey nonny-nonny", "hallelujah" or "alack-a-day", it cannot yet have been speech. For that to arise, according to Langer, it was necessary for such sequences to be emitted increasingly out of context – outside the total situation that gave rise to them. Extending a set of associations from one cognitive context to another, completely different one, is the secret of metaphor. Langer invokes an early version of what is nowadays termed "grammaticalization" theory to show how, from, such a point of departure, syntactically complex speech might progressively have arisen.
 * Langer acknowledges Emile Durkheim as having proposed a strikingly similar theory back in 1912. For recent thinking along broadly similar lines, see Steven Brown on "musilanguage", Chris Knight on "ritual" and "play", Jerome Lewis on "mimicry", Steven Mithen on "Hmmmmm" Bruce Richman on "nonsense syllables" and Alison Wray on "holistic protolanguage".
 * Mirror neuron hypothesis (MSH) and the Motor Theory of Speech Perception
 * Illustration-of-the-mirror-neuron-system-by-Jan-Brascamp.jpg
 * The mirror neuron hypothesis, based on a phenomenon discovered in 2008 by Rizzolatti and Fabbri, supports the motor theory of speech perception. The motor theory of speech perception was proposed in 1967 by Liberman, who believed that the motor system and language systems were closely interlinked. This would result in a more streamlined process of generating speech; both the cognition and speech formulation could occur simultaneously. Essentially, it is wasteful to have a speech decoding and speech encoding process independent of each other. This hypothesis was further supported by the discovery of motor neurons. Rizzolatti and Fabbri found that there were specific neurons in the motor cortex of macaque monkeys which were activated when seeing an action. The neurons which are activated are the same neurons in which would be required to perform the same action themselves. Mirror neurons fire when observing an action and performing an action, indicating that these neurons found in the motor cortex are necessary for understanding a visual process. The presence of mirror neurons may indicate that non-verbal, gestural communication is far more ancient than previously thought to be. Motor theory of speech perception relies on the understanding of motor representations that underlie speech gestures, such as lip movement. There is no clear understanding of speech perception currently, but it is generally accepted that the motor cortex is activated in speech perception to some capacity.
 * ===="Musilanguage"====
 * The term "musilanguage" (or "hmmmmm") refers to a pre-linguistic system of vocal communication from which (according to some scholars) both music and language later derived. The idea is that rhythmic, melodic, emotionally expressive vocal ritual helped bond coalitions and, over time, set up selection pressures for enhanced volitional control over the speech articulators. Patterns of synchronized choral chanting are imagined to have varied according to the occasion. For example, "we're setting off to find honey" might sound qualitatively different from "we're setting off to hunt" or "we're grieving over our relative's death". If social standing depended on maintaining a regular beat and harmonizing one's own voice with that of everyone else, group members would have come under pressure to demonstrate their choral skills.
 * Archaeologist Steven Mithen speculates that the Neanderthals possessed some such system, expressing themselves in a "language" known as "Hmmmmm", standing for Holistic, manipulative, multi-modal, musical and mimetic. p. 169-175 In Bruce Richman's earlier version of essentially the same idea, frequent repetition of the same few songs by many voices made it easy for people to remember those sequences as whole units. Activities that a group of people were doing whilst they were vocalizing together – activities that were important or striking or richly emotional – came to be associated with particular sound sequences, so that each time a fragment was heard, it evoked highly specific memories. The idea is that the earliest lexical items (words) started out as abbreviated fragments of what were originally communal songs.
 * As group members accumulated an expanding repertoire of songs for different occasions, interpersonal call-and-response patterns evolved along one trajectory to assume linguistic form. Meanwhile, along a divergent trajectory, polyphonic singing and other kinds of music became increasingly specialised and sophisticated.
 * To explain the establishment of syntactical speech, Richman cites English "I wanna go home". He imagines this to have been learned in the first instance not as a combinatorial sequence of free-standing words, but as a single stuck-together combination – the melodic sound people make to express "feeling homesick". Someone might sing "I wanna go home", prompting other voices to chime in with "I need to go home", "I'd love to go home", "Let's go home" and so forth. Note that one part of the song remains constant, whilst another is permitted to vary. If this theory is accepted, syntactically complex speech began evolving as each chanted mantra allowed for variation at a certain point, allowing for the insertion of an element from some other song. For example, whilst mourning during a funeral rite, someone might want to recall a memory of collecting honey with the deceased, signaling this at an appropriate moment with a fragment of the "we're collecting honey" song. Imagine that such practices became common. Meaning-laden utterances would now have become subject to a distinctively linguistic creative principle – that of recursive embedding.
 * ====Hunter-gatherer egalitarianism====
 * Mbendjele meat sharing.jpg
 * Many scholars associate the evolutionary emergence of speech with profound social, sexual, political and cultural developments. One view is that primate-style dominance needed to give way to a more cooperative and egalitarian lifestyle of the kind characteristic of modern hunter-gatherers.
 * =====Intersubjectivity=====
 * According to Michael Tomasello, the key cognitive capacity distinguishing Homo sapiens from our ape cousins is "intersubjectivity". This entails turn-taking and role-reversal: your partner strives to read your mind, you simultaneously strive to read theirs, and each of you makes a conscious effort to assist the other in the process. The outcome is that each partner forms a representation of the other's mind in which their own can be discerned by reflection.
 * Tomasello argues that this kind of bi-directional cognition is central to the very possibility of linguistic communication. Drawing on his research with both children and chimpanzees, he reports that human infants, from one year old onwards, begin viewing their own mind as if from the standpoint of others. He describes this as a cognitive revolution. Chimpanzees, as they grow up, never undergo such a revolution. The explanation, according to Tomasello, is that their evolved psychology is adapted to a deeply competitive way of life. Wild-living chimpanzees from despotic social hierarchies, most interactions involving calculations of dominance and submission. An adult chimp will strive to outwit its rivals by guessing at their intentions whilst blocking them from reciprocating. Since bi-directional intersubjective communication is impossible under such conditions, the cognitive capacities necessary for language don't evolve.
 * =====Counter-dominance=====
 * In the scenario favoured by David Erdal and Andrew Whiten, primate-style dominance provoked equal and opposite coalitionary resistance – counter-dominance. During the course of human evolution, increasingly effective strategies of rebellion against dominant individuals led to a compromise. Whilst abandoning any attempt to dominate others, group members vigorously asserted their personal autonomy, maintaining their alliances to make potentially dominant individuals think twice. Within increasingly stable coalitions, according to this perspective, status began to be earned in novel ways, social rewards accruing to those perceived by their peers as especially cooperative and self-aware.
 * =====Reverse dominance=====
 * Whilst counter-dominance, according to this evolutionary narrative, culminates in a stalemate, anthropologist Christopher Boehm extends the logic a step further. Counter-dominance tips over at last into full-scale "reverse dominance". The rebellious coalition decisively overthrows the figure of the primate alpha-male. No dominance is allowed except that of the self-organised community as a whole.
 * As a result of this social and political change, hunter-gatherer egalitarianism is established. As children grow up, they are motivated by those around them to reverse perspective, engaging with other minds on the model of their own. Selection pressures favor such psychological innovations as imaginative empathy, joint attention, moral judgment, project-oriented collaboration and the ability to evaluate one's own behaviour from the standpoint of others. Underpinning enhanced probabilities of cultural transmission and cumulative cultural evolution, these developments culminated in the establishment of hunter-gatherer-style egalitarianism in association with intersubjective communication and cognition. It is in this social and political context that language evolves.
 * ====Scenarios involving mother-infant interactions====
 * ====="Putting the baby down"=====
 * According to Dean Falk's "putting the baby down" theory, vocal interactions between early hominin mothers and infants sparked a sequence of events that led, eventually, to our ancestors' earliest words. The basic idea is that evolving human mothers, unlike their monkey and ape counterparts, couldn't move around and forage with their infants clinging onto their backs. Loss of fur in the human case left infants with no means of clinging on. Frequently, therefore, mothers had to put their babies down. As a result, these babies needed reassurance that they were not being abandoned. Mothers responded by developing "motherese" – an infant-directed communicative system embracing facial expressions, body language, touching, patting, caressing, laughter, tickling and emotionally expressive contact calls. The argument is that language somehow developed out of all this.
 * Criticism
 * Whilst this theory may explain a certain kind of infant-directed "protolanguage" – known today as "motherese" – it does little to solve the really difficult problem, which is the emergence amongst adults of syntactical speech.
 * =====Co-operative breeding=====
 * Evolutionary anthropologist Sarah Hrdy observes that only human mothers amongst great apes are willing to let another individual take hold of their own babies; further, we are routinely willing to let others babysit. She identifies lack of trust as the major factor preventing chimpanzee, bonobo or gorilla mothers from doing the same: "If ape mothers insist on carrying their babies everywhere ... it is because the available alternatives are not safe enough". The fundamental problem is that ape mothers (unlike monkey mothers who may often babysit) do not have female relatives nearby. The strong implication is that, in the course of Homo evolution, allocare could develop because Homo mothers did have female kin close by – in the first place, most reliably, their own mothers. Extending the Grandmother hypothesis, Hrdy argues that evolving Homo erectus females necessarily relied on female kin initially; this novel situation in ape evolution of mother, infant and mother's mother as allocarer provided the evolutionary ground for the emergence of intersubjectivity. She relates this onset of "cooperative breeding in an ape" to shifts in life history and slower child development, linked to the change in brain and body size from the 2 million year mark.
 * Primatologist Klaus Zuberbühler uses these ideas to help explain the emergence of vocal flexibility in the human species. Co-operative breeding would have compelled infants to struggle actively to gain the attention of caregivers, not all of whom would have been directly related. A basic primate repertoire of vocal signals may have been insufficient for this social challenge. Natural selection, according to this view, would have favoured babies with advanced vocal skills, beginning with babbling (which triggers positive responses in care-givers) and paving the way for the elaborate and unique speech abilities of modern humans.
 * =====Was "mama" the first word?=====
 * These ideas might be linked to those of the renowned structural linguist Roman Jakobson, who claimed that "the sucking activities of the child are accompanied by a slight nasal murmur, the only phonation to be produced when the lips are pressed to the mother's breast ... and the mouth is full". He proposed that later in the infant's development, "this phonatory reaction to nursing is reproduced as an anticipatory signal at the mere sight of food and finally as a manifestation of a desire to eat, or more generally, as an expression of discontent and impatient longing for missing food or absent nurser, and any ungranted wish". So, the action of opening and shutting the mouth, combined with the production of a nasal sound when the lips are closed, yielded the sound sequence "Mama", which may, therefore, count as the very first word. Peter MacNeilage sympathetically discusses this theory in his major book, The Origin of Speech, linking it with Dean Falk's "putting the baby down" theory (see above). Needless to say, other scholars have suggested completely different candidates for Homo sapiens' very first word.
 * ====Niche construction theory====
 * Beaver dam in Tierra del Fuego.jpgt the biological language faculty is genetically inherited, actual languages or dialects are culturally transmitted, as are social norms, technological traditions and so forth. Biologists expect a robust co-evolutionary trajectory linking human genetic evolution with the evolution of culture. Individuals capable of rudimentary forms of protolanguage would have enjoyed enhanced access to cultural understandings, whilst these, conveyed in ways that young brains could readily learn, would, in turn, have become transmitted with increasing efficiency.
 * In some ways like beavers, as they construct their dams, humans have always engaged in niche construction, creating novel environments to which they subsequently become adapted. Selection pressures associated with prior niches tend to become relaxed as humans depend increasingly on novel environments created continuously by their own productive activities. According to Steven Pinker, language is an adaptation to "the cognitive niche". Variations on the theme of ritual/speech co-evolution – according to which speech evolved for purposes of internal communication within a ritually constructed domain – have attempted to specify more precisely when, why and how this special niche was created by human collaborative activity.
 * ==Conceptual frameworks==
 * ===Structuralism===
 * The Swiss scholar Ferdinand de Saussure founded linguistics as a twentieth-century professional discipline. Saussure regarded a language as a rule-governed system, much like a board game such as chess. In order to understand chess, he insisted, we must ignore such external factors as the weather prevailing during a particular session or the material composition of this or that piece. The game is autonomous with respect to its material embodiments. In the same way, when studying language, it's essential to focus on its internal structure as a social institution. External matters (e.g., the shape of the human tongue) are irrelevant from this standpoint. Saussure regarded 'speaking' (parole) as individual, ancillary and more or less accidental by comparison with "language" (langue), which he viewed as collective, systematic and essential.
 * Saussure showed little interest in Darwin's theory of evolution by natural selection. Nor did he consider it worthwhile to speculate about how language might originally have evolved. Saussure's assumptions in fact cast doubt on the validity of narrowly conceived origins scenarios. His structuralist paradigm, when accepted in its original form, turns scholarly attention to a wider problem: how our species acquired the capacity to establish social institutions in general.
 * ===Behaviourism===
 * In the United States, prior to and immediately following World War II, the dominant psychological paradigm was behaviourism. Within this conceptual framework, language was seen as a certain kind of behaviour – namely, verbal behaviour, to be studied much like any other kind of behaviour in the animal world. Rather as a laboratory rat learns how to find its way through an artificial maze, so a human child learns the verbal behaviour of the society into which it is born. The phonological, grammatical and other complexities of speech are in this sense "external" phenomena, inscribed into an initially unstructured brain. Language's emergence in Homo sapiens, from this perspective, presents no special theoretical challenge. Human behaviour, whether verbal or otherwise, illustrates the malleable nature of the mammalian – and especially the human – brain.
 * ===Chomskyan Nativism===
 * PhrenologyPix.jpg is an idea which was prefigured in some respects by the 19th-century movement of phrenology.]]
 * Nativism is the theory that humans are born with certain specialised cognitive modules enabling us to acquire highly complex bodies of knowledge such as the grammar of a language.
 * From the mid-1950s onwards, Noam Chomsky, Jerry Fodor and others mounted what they conceptualised as a 'revolution' against behaviourism. Retrospectively, this became labelled 'the cognitive revolution'.  Whereas behaviourism had denied the scientific validity of the concept of "mind", Chomsky replied that, in fact, the concept of "body" is more problematic. Behaviourists tended to view the child's brain as a tabula rasa, initially lacking structure or cognitive content. According to B. F. Skinner, for example, richness of behavioural detail (whether verbal or non-verbal) emanated from the environment. Chomsky turned this idea on its head. The linguistic environment encountered by a young child, according to Chomsky's version of psychological nativism, is in fact hopelessly inadequate. No child could possibly acquire the complexities of grammar from such an impoverished source. Far from viewing language as wholly external, Chomsky re-conceptualised it as wholly internal. To explain how a child so rapidly and effortlessly acquires its natal language, he insisted, we must conclude that it comes into the world with the essentials of grammar already pre-installed. No other species, according to Chomsky, is genetically equipped with a language faculty – or indeed with anything remotely like one. The emergence of such a faculty in Homo sapiens, from this standpoint, presents biological science with a major theoretical challenge.
 * ===Speech act theory===
 * One way to explain biological complexity is by reference to its inferred function. According to the influential philosopher John Austin, speech's primary function is active in the social world.
 * Speech acts, according to this body of theory, can be analyzed on three different levels: elocutionary, illocutionary and perlocutionary. An act is locutionary when viewed as the production of certain linguistic sounds – for example, practicing correct pronunciation in a foreign language. An act is illocutionary insofar as it constitutes an intervention in the world as jointly perceived or understood. Promising, marrying, divorcing, declaring, stating, authorizing, announcing and so forth are all speech acts in this illocutionary sense. An act is perlocutionary when viewed in terms of its direct psychological effect on an audience. Frightening a baby by saying 'Boo!' would be an example of a "perlocutionary" act.
 * For Austin, "doing things" with words means, first and foremost, deploying illocutionary force. The secret of this is community participation or collusion. There must be a 'correct' (conventionally agreed) procedure, and all those concerned must accept that it has been properly followed. In the case of a priest declaring a couple to be man and wife, his words will have illocutionary force only if he is properly authorised and only if the ceremony is properly conducted, using words deemed appropriate to the occasion. Austin points out that should anyone attempt to baptise a penguin, the act would be null and void. For reasons which have nothing to do with physics, chemistry or biology, baptism is inappropriate to be applied to penguins, irrespective of the verbal formulation used.
 * This body of theory may have implications for speculative scenarios concerning the origins of speech. "Doing things with words" presupposes shared understandings and agreements pertaining not just to language but to social conduct more generally. Apes might produce sequences of structured sound, influencing one another in that way. To deploy illocutionary force, however, they would need to have entered a non-physical and non-biological realm – one of shared contractual and other intangibles. This novel cognitive domain consists of what philosophers term "institutional facts" – objective facts whose existence, paradoxically, depends on communal faith or belief. Few primatologists, evolutionary psychologists or anthropologists consider that nonhuman primates are capable of the necessary levels of joint attention, sustained commitment or collaboration in pursuit of future goals.
 * ===Biosemiotics===
 * DNA animation.gif]]
 * Biosemiotics is a relatively new discipline, inspired in large part by the discovery of the genetic code in the early 1960s. Its basic assumption is that Homo sapiens is not alone in its reliance on codes and signs. Language and symbolic culture must have biological roots, hence semiotic principles must apply also in the animal world.
 * The discovery of the molecular structure of DNA apparently contradicted the idea that life could be explained, ultimately, in terms of the fundamental laws of physics. The letters of the genetic alphabet seemed to have "meaning", yet meaning is not a concept that has any place in physics. The natural science community initially solved this difficulty by invoking the concept of "information", treating information as independent of meaning. But a different solution to the puzzle was to recall that the laws of physics in themselves are never sufficient to explain natural phenomena. To explain, say, the unique physical and chemical characteristics of the planets in our solar system, scientists must work out how the laws of physics became constrained by particular sequences of events following the formation of the Sun.
 * According to Howard Pattee, the same principle applies to the evolution of life on earth, a process in which certain "frozen accidents" or "natural constraints" have from time to time drastically reduced the number of possible evolutionary outcomes. Codes, when they prove to be stable over evolutionary time, are constraints of this kind. The most fundamental such "frozen accident" was the emergence of DNA as a self-replicating molecule, but the history of life on earth has been characterised by a succession of comparably dramatic events, each of which can be conceptualised as the emergence of a new code. From this perspective, the evolutionary emergence of spoken language was one more event of essentially the same kind.
 * ===The handicap principle===
 * [[Image:Peacock front02 - melbourne zoo.jpg|thumb|upright|A peacock's tail: a classic example of costly signalling]]
 * In 1975, the Israeli theoretical biologist Amotz Zahavi  proposed a novel theory which, although controversial, has come to dominate Darwinian thinking on how signals evolve. Zahavi's "handicap principle" states that to be effective, signals must be reliable; to be reliable, the bodily investment in them must be so high as to make cheating unprofitable.
 * Paradoxically, if this logic is accepted, signals in nature evolve not to be efficient but, on the contrary, to be elaborate and wasteful of time and energy. A peacock's tail is the classic illustration. Zahavi's theory is that since peahens are on the look-out for male braggarts and cheats, they insist on a display of quality so costly that only a genuinely fit peacock could afford to pay. Needless to say, not all signals in the animal world are quite as elaborate as a peacock's tail. But if Zahavi is correct, all require some bodily investment – an expenditure of time and energy which "handicaps" the signaller in some way.
 * Animal vocalizations (according to Zahavi) are reliable because they are faithful reflections of the state of the signaller's body. To switch from an honest to a deceitful call, the animal would have to adopt a different bodily posture. Since every bodily action has its own optimal starting position, changing that position to produce a false message would interfere with the task of carrying out the action really intended. The gains made by cheating would not make up for the losses incurred by assuming an improper posture – and so the phony message turns out to be not worth its price. p. 69 This may explain, in particular, why ape and monkey vocal signals have evolved to be so strikingly inflexible when compared with the varied speech sounds produced by the human tongue. The apparent inflexibility of chimpanzee vocalizations may strike the human observer as surprising until we realize that being inflexible is necessarily bound up with being perceptibly honest in the sense of "hard-to-fake".
 * If we accept this theory, the emergence of speech becomes theoretically impossible. Communication of this kind just cannot evolve. The problem is that words are cheap. Nothing about their acoustic features can reassure listeners that they are genuine and not fakes. Any strategy of reliance on someone else's tongue – perhaps the most flexible organ in the body – presupposes unprecedented levels of honesty and trust. To date, Darwinian thinkers have found it difficult to explain the requisite levels of community-wide cooperation and trust.
 * An influential standard textbook is Animal Signals, by John Maynard Smith and David Harper. These authors divide the costs of communication into two components, (1) the investment necessary to ensure transmission of a discernible signal; (2) the investment necessary to guarantee that each signal is reliable and not a fake. The authors point out that although costs in the second category may be relatively low, they are not zero. Even in relatively relaxed, cooperative social contexts – for example, when communication is occurring between genetic kin – some investment must be made to guarantee reliability. In short, the notion of super-efficient communication – eliminating all costs except those necessary for successful transmission – is biologically unrealistic. Yet speech comes precisely into this category.
 * Handicap-signal-of-quality.png
 * The graph shows the different signal intensities as a result of costs and benefits. If two individuals face different costs but have the same benefits, or have different benefits but the same cost, they will signal at different levels. The higher signal represents a more reliable quality. The high-quality individual will maximise costs relative to benefits at a high signal intensities, whilst the low-quality individual maximises their benefits relative to cost at low signal intensity. The high-quality individual is shown to take more risks (greater cost), which can be understood in terms of honest signals, which are expensive. The stronger you are, the more easily you can bear the cost of the signal, making you a more appealing mating partner. The low-quality individuals are less likely to be able to afford a specific signal, and will consequently be less likely to attract a female.
 * ===Cognitive linguistics===
 * Cognitive linguistics views linguistic structure as arising continuously out of usage. Speakers are forever discovering new ways to convey meanings by producing sounds, and in some cases, these novel strategies become conventionalised. Between the phonological structure and semantic structure, there is no causal relationship. Instead, each novel pairing of sound and meaning involves an imaginative leap.
 * In their book, Metaphors We Live By, George Lakoff and Mark Johnson helped pioneer this approach, claiming that metaphor is what makes human thought special. All language, they argued, is permeated with metaphor, whose use in fact constitutes distinctively human – that is, distinctively abstract – thought. To conceptualise things which cannot be directly perceived – intangibles such as time, life, reason, mind, society or justice – we have no choice but to set out from more concrete and directly perceptible phenomena such as motion, location, distance, size and so forth. In all cultures across the world, according to Lakoff and Johnson, people resort to such familiar metaphors as ideas are locations, thinking is moving and mind is body. For example, we might express the idea of "arriving at a crucial point in our argument" by proceeding as if literally traveling from one physical location to the next.
 * Metaphors, by definition, are not literally true. Strictly speaking, they are fictions – from a pedantic standpoint, even falsehoods. But if we couldn't resort to metaphorical fictions, it's doubtful whether we could even form conceptual representations of such nebulous phenomena as "ideas", thoughts", "minds", and so forth.
 * The bearing of these ideas on current thinking on speech origins remains unclear. One suggestion is that ape communication tends to resist the metaphor for social reasons. Since they inhabit a Darwinian (as opposed to morally regulated) social world, these animals are under strong competitive pressure not to accept patent fictions as valid communicative currency. Ape vocal communication tends to be inflexible, marginalizing the ultra-flexible tongue, precisely because listeners treat with suspicion any signal which might prove to be a fake. Such insistence on perceptible veracity is clearly incompatible with metaphoric usage. An implication is that neither articulate speech nor distinctively human abstract thought could have begun evolving until our ancestors had become more cooperative and trusting of one another's communicative intentions.
 * ===Natural science vs social science interpretations===
 * ====Social reality====
 * When people converse with one another, according to the American philosopher John Searle, they're making moves, not in the real world which other species inhabit, but in a shared virtual realm peculiar to ourselves. Unlike the deployment of muscular effort to move a physical object, the deployment of illocutionary force requires no physical effort (except the movement of the tongue/mouth to produce speech) and produces no effect which any measuring device could detect. Instead, our action takes place on a quite different level – that of social reality. This kind of reality is in one sense hallucinatory, being a product of collective intentionality. It consists, not of "brute facts" – facts which exist anyway, irrespective of anyone's belief – but of "institutional facts", which "exist" only if you believe in them. Government, marriage, citizenship and money are examples of "institutional facts". One can distinguish between "brute" facts and "institutional" ones by applying a simple test. Suppose no one believed in the fact – would it still be true? If the answer is "yes", it's "brute". If the answer is "no", it's "institutional".
 * The facts of language in general and of speech, in particular, are, from this perspective, "institutional" rather than "brute". The semantic meaning of a word, for example, is whatever its users imagine it to be. To "do things with words" is to operate in a virtual world which seems real because we share it in common. In this incorporeal world, the laws of physics, chemistry, and biology do not apply. That explains why illocutionary force can be deployed without exerting muscular effort. Apes and monkeys inhabit the "brute" world. To make an impact, they must scream, bark, threaten, seduce or in other ways invest bodily effort. If they were invited to play chess, they would be unable to resist throwing their pieces at one another. Speech is not like that. A few movements of the tongue, under appropriate conditions, can be sufficient to open parliament, annul a marriage, confer a knighthood or declare war. To explain, on a Darwinian basis, how such apparent magic first began to work, we must ask how, when and why Homo sapiens succeeded in establishing the wider domain of institutional facts.
 * ====Nature or society?====
 * "Brute facts", in the terminology of speech act philosopher John Searle, are facts which are true anyway, regardless of human belief. For example, a person might not believe in gravity; however, if the person jumped over a cliff, they would still fall. Natural science is the study of facts of this kind. "Institutional facts" are fictions accorded factual status within human social institutions. Monetary and commercial facts are fictions of this kind. The complexities of today's global currency system are facts only whilst society believes in them: suspend the belief and the facts correspondingly dissolve. Yet although institutional facts rest on human belief, that doesn't make them mere distortions or hallucinations. Take a person's confidence that two five-pound banknotes are worth ten pounds. That is not merely a subjective belief: it's an objective, indisputable fact. But now imagine a collapse of public confidence in the currency system. Suddenly, the realities in a person's pocket dissolve.
 * Scholars who doubt the scientific validity of the notion of "institutional facts" include Noam Chomsky, for whom language is not social. In Chomsky's view, language is a natural object (a component of the individual brain) and its study, therefore, a branch of natural science. In explaining the origin of language, scholars in this intellectual camp invoke non-social developments – in Chomsky's case, a random genetic mutation. Chomsky argues that language might exist inside the brain of a single mutant gorilla even if no one else believed in it, even if no one else existed apart from the mutant – and even if the gorilla in question remained unaware of its existence, never actually speaking. In the opposite philosophical camp are those who, in the tradition of Ferdinand de Saussure, argue that if no one believed in words or rules, they simply would not exist. These scholars, correspondingly, regard language as essentially institutional, concluding that linguistics should be considered a topic within social science. In explaining the evolutionary emergence of language, scholars in this intellectual camp tend to invoke profound changes in social relationships.
 * Criticism. Darwinian scientists today see little value in the traditional distinction between "natural" and "social" science. Darwinism in its modern form is the study of cooperation and competition in nature – a topic which is intrinsically social. Against this background, there is an increasing awareness amongst evolutionary linguists and Darwinian anthropologists that traditional inter-disciplinary barriers can have damaging consequences for investigations into the origins of speech.

Plans for Rewrites (No-Merge Decision Aftermath)
Thanks, @Doric Loon and @Klbrain, for concurring and for help. There's more, though. Even with that extraneous material dispatched, this is not better than Origin of Language, which is apparently graded as C-Class, however those grades are given. Can this be downgraded to C as well? I'm not convinced it should be High Importance, either, or at least not higher than Origin of Language. As for me rewriting the head, I'm sympathetic and interested, but as a researcher in the area I've got a subjective opinion about what's what. I can write objectively about the material and about my scientific opponents, but I'd want somebody to supervise my potential conflicts of interest and my adherence to Wikipedia mission boundaries. What is the mechanism for that? Regardless of my sympathy and interest, I'm staring down the barrels of 4 deadlines and can't commit to even looking at just reworking the article head until Christmas break, if then. Meantime, I encourage anybody to make any improvements that inspire them. (FYI, Doric Loon, recent research makes it substantially less likely that speech and language evolved in parallel, so the dispute against that previously long-held consensus is part of what needs discussing here.) Frphnflng (talk) 20:32, 6 September 2023 (UTC)
 * Given your views, I've changed the project assessments; any user can review, and as you've looked through the pages carefully and have subject expertise, your view is sufficient to justify the change. Regarding conflict of interest, if you're looking to cite your own work or reviews, then I suggest using Template:Edit COI here; otherwise, proceed with editing and if someone disagrees then they can revert and discuss here on the talk page. Don't worry about the timescale; working on it at some point over the next few months seems very reasonsable (and very helpful!). Klbrain (talk) 11:20, 7 September 2023 (UTC)
 * @Frphnflng What you just said about recent research seems so counter-intuitive to me that we definitely need your expertise. I'm also a university teacher and researcher (in quite a different field), and if you look at my userpage (User:Doric Loon) towards the bottom you'll see what I've written there about Conflicts of Interest - you would be wise to do something like that to protect yourself. But beyond that, you should feel free to edit on the basis of your expertise, and it is OK to cite your own work if you tell us you are doing so. Doric Loon (talk) 18:45, 7 September 2023 (UTC)
