Talk:Ring species

"The herring gull complex is not a ring species" ?
Can someone comment on the following: The herring gull complex is not a ring species We may have to change our example. —Preceding unsigned comment added by Gareth Owen (talk • contribs) 15:22, 19 May 2006
 * From the abstract, it looks like the paper is just saying that the ring isn't closed: ... Contrary to the ring-species model, we find no genetic evidence for a closure of the circumpolar ring through colonization of Europe by North American herring gulls. However, closure of the ring in the opposite direction may be imminent, with lesser black-backed gulls about to colonize North America. My ill-informed guess is that the phrase 'ring species' is used loosely by some and strictly by others. The title of the paper is amusingly ironic in the context of the wiki article, though.

"Ring species" is a term used mostly in zoological circles, but there are apparently no examples of "ring species" in the strict sense in studied vertebrates. Ensatina & Phylloscopus are almost certainly not ring species. In Ensatina, the "ring" formed by the Sierra Nevada, Coast Ranges, and Transverse Ranges in California apparently has a permeable center, with salamanders able to cross the Central Valley (at least historically). In Phylloscopus, the data suggest an eastern and western clade that have both relatively recently colonized both the supposed ancestral area and the supposed re-contact zone. The term persists in zoological literature because the concept is "sexy" rather than because it has empirical applicability or relevance. There may be plant examples, but if so they are rare. --Patrick Alexander (too lazy to login) — Preceding undated comment added 03:01, 3 December 2006

Diagram
The diagram's explanation is unclear. For instance, it says:
 * Interbreeding between two populations is shown by a grey zone.

while there is no grey in the diagram. Palpalpalpal 20:32, 3 April 2007 (UTC)

Herring Gull
My understanding is that this is no longer considered to be a good example. see. However there is greenish warbler which is. Wilmot1 05:06, 9 August 2007 (UTC)

Other examples
These are relatively small scale examples that are listed. It escapes me at the moment, but isn't the canonical example some "species" of bird found the whole world over? --Belg4mit (talk) 00:27, 4 January 2008 (UTC)

I wonder if domestic dogs might be an example of this. All dogs are considered one species, but is it physically even possible for a chihuahua to breed with a great dane? Worth some research, particularly given that an average reader will be able to better visualize this concept in dogs than some bird species. postdlf (talk) 15:55, 9 October 2010 (UTC)


 * I would like to see the question of dog breeds explicitly addressed in the article - Are dog breeds an example of a ring species or are they not? (if not, why not) ) 28 March 2011  —Preceding unsigned comment added by 166.137.143.161 (talk) 16:17, 28 March 2011 (UTC)
 * No, because they fail the requirement that geographically separate populations be incapable of interbreeding. --Belg4mit (talk) 06:04, 29 March 2011 (UTC)

Have there been any tests to establish whether these species CANnot breed, or simply do not? Would artificial procedures produce viable offspring? 80.7.95.188 (talk) 23:34, 9 June 2011 (UTC)
 * Do not is the same as cannot in the wild. Behavioral incompatibility is just as strong a barrier as genetic incompatibility, and will eventually become genetic incompatibility because of drift.  So the possibility of artificial procedures producing viable offspring is wholly irrelevant.  --69.209.75.199 (talk) 08:43, 11 August 2011 (UTC)
 * Practically it's meaningless but it's not irrelevant to the issue of Speciation for those trying to find a very narrow definition.--70.128.114.23 (talk) 04:39, 7 October 2011 (UTC)

Link to Youtube video
Why is there a link to a Youtube user's video at the bottom? It's a good video, but it should not count as a source or reference... that is reserved for 'verifiable' works e.g. BBC news articles or referenced papers, no? 93.19.150.5 (talk) 16:00, 12 April 2012 (UTC)

Ensatina
I see that Ensatina has been removed as an example of a ring species. I'm aware of the dispute over the last few years about Ensatina as a good example of a ring species, but it's given as an example in so many textbooks and popular science books, it's quite conspicuous by its absence. There ought to be a short section included in this article about Ensatina and the ways it does and does not conform to the concept of ring species.

Analogies in linguistics
It would be good to add a link here to the analogous phenomenon in linguistics, I.e. Mutual intelligibility, where languages may change gradually over a geographic space and become sperate languages. Fig (talk) 10:18, 18 October 2015 (UTC)
 * I guess you mean Dialect continuum? It is an interesting analogy, but I do not know how it would be integrated in the article without it becoming original research. Besides, a clean Ring Species goes around in a ring, and I do not know of any dialect continuum that goes around a mountain or a geographic pole. Mlewan (talk) 19:01, 18 October 2015 (UTC)


 * If you can provide a reliable source where an author create a parallel, then it could possibly be included. However, I highly doubt any source will correlate dialects to species.  Andrew. Z. Colvin  •  Talk  06:59, 14 December 2016 (UTC)

Updates needed, see Coyne
There are no ring species « Why Evolution Is True by Jerry Coyne provides links to papers superseding the studies cited in this article: for example,. Also, The herring gull complex is not a ring species gives open access to pdf of the paper, "Electronic Appendix" in our article seems to be a dead link. . . dave souza, talk 06:28, 24 August 2016 (UTC)


 * I will try to work on this article, adding up-to-date research as soon as I can. It needs a major overhaul and most certainly needs the include the dissenting research. Evidence of common descent has a more up-to-date synopsis of ring species work and includes far more proposed examples than listed here.  Andrew. Z. Colvin  •  Talk  06:55, 14 December 2016 (UTC)
