Black eyes
I reverted these edits by Wikkedout because, like I stated in that edit summary, the editor needs WP:Reliable sources stating that true black eyes exist. As it stands, the editor added nothing but WP:Original research; for three parts, also seen in that link, he or she also changed text that is supported by three different reliable sources. And the formatting style, capitalizing both "brown" and "black," violated Manual of Style. Flyer22 (talk) 00:04, 18 January 2013 (UTC)

Y-DNA relevance?

 * Y-Chromosome DNA testing performed on ancient Scythian skeletons dating to the Bronze and Iron Ages in the Siberian Krasnoyarsk region found that 10 out of the 11 subjects carried Y-DNA R1a1 (most commonly found today in Eastern Europe, Afghanistan and the northern Indian Subcontinent), with blue or green eye color and light hair common, suggesting mostly European origin of that particular population.

How is this relevant? Y-ancestry doesn't necessarily tell us anything about the autosomal genes. —Tamfang (talk) 03:38, 24 January 2013 (UTC)

How to align photos- 8 month photos of the same iris changing color from Amber to Hazel
Hello.

I would like to know how I should format the photos I have taken. They are both photos of my eye, the same pupil 8 months apart from june2012-Febuary2013 and they document the color change from Amber to Hazel. I had no abnormal hormone changes, nor scenery, or lifestyle changes and as a result those have been ruled out as a possible cause for the color changes. The pupils will revert back to Amber and again to hazel approximately once a year, becoming lighter, green/yellow in Winter and a deeper orange/gold in Summer. I've uploaded the photos to commons.

Hazel Eyes
The description of hazel eyes is providig people with the misconception of hazel eyes being green and brown or any multi-coloured iris, when the original/actual concept of hazel eyes was eyes that are light brown, gold & brown, orange brown, basically an eye that resembles a hazelnut shell hence the word hazel. However this true meaning has only been given a one lined description at the bottom of the hazel eyed section. I propose the hazel eyed section be changed to state what true hazel eyes are more in depth and as the first paragraph and then state what the modern misconception of hazel eyes are in a 2nd paragraph while stating the origin of this misconception (North America) and when it started (most likely in the past 100 years). 110.174.147.166 (talk) 14:11, 25 January 2013‎ (UTC)


 * IP, look at what I stated on your talk page in the Sourcing section. You have to provide WP:Reliable sources for these assertions. Flyer22 (talk) 17:18, 25 January 2013 (UTC)


 * Words change their meanings. It might be the case that "hazel" originally meant one thing but that as the IP says "in the past 100 years" it has come to mean something else. The modern meaning of a term is not a "misconception" -- it's simply a different definition than an earlier one. If someone questions this idea that newer established meanings are not wrong, then he'd better be prepared to examine every word of his post to make sure he's not misusing most of the words in it. Duoduoduo (talk) 17:32, 25 January 2013 (UTC)

The misconception started in North America and is only used in North America and certain other countries that have been exposed to Americanisation e.g. Australia and New Zealand. The term hazel started in Europe, which is where light eyes and the hazel nut come from, and a european from europe would find green and brown or any multi-coloured eye being considered hazel to be quite odd considering it does not match a hazelnut. if your willing to change the hazelnut section to inform people of the true meaning and misconcepted meaning i would happily provide sources, but it's just common sense really that a hazel eye is one that matches a hazelnut. — Preceding unsigned comment added by 110.174.147.166 (talk) 14:47, 27 January 2013 (UTC)
 * We have to go by reliable sources on this. While WP:COMMONSENSE is allowed; it's not in cases like this. If you provide reliable sources (even just one reliable source) on this talk page for your assertions (even just one assertion), then we can add something about that in the Hazel eye section (the section is not called Hazelnut, nor should it be). Flyer22 (talk) 15:56, 27 January 2013 (UTC)
 * As for what you want inserted about the "true meaning," the line in the Hazel section about hazelnut uses the word "sometimes." It states: "Definitions of the eye color hazel vary: it is sometimes considered to be synonymous with light brown or gold, as in the color of a hazelnut shell." And four reliable sources are used to support that line; it is worth checking those sources to see if they actually support that line, whether fully or partly, however.

 * (ec)I checked a few of them but didn't find any that are reliable sources by Wikipedia standards. What you have to try to understand is that the question of what eye color is or is not hazel is not a scientific question -- it is a question of what words mean in the English language as this language currently exists. Several of these sources admit that the North American language has evolved in the past hundred years, and that "hazel" now means a combination of light brown and green in American English.


 * Here's some entries from some reliable sources of meaning of words. From Random House Webster's College Dictionary [of American English], entry "hazel": a light golden- or greenish-brown color. From Wiktionary: A greenish-brown colour, the colour of a ripe hazelnut.  From http://www.merriam-webster.com/dictionary/hazel?show=0&t=1359387138 :  (a) : of the color hazel; (b) of eyes : of a variable color averaging light greenish-grayish brown.  So that's it -- words mean what they mean, not what they used to mean or what people wish they still meant. Duoduoduo (talk) 15:39, 28 January 2013 (UTC)
 * Are you replying to us both, Duoduoduo? As for "what eye color is or is not hazel" not being a scientific question, it seems to be that it is...if the sources backing the hazelnut line I mentioned above do discuss that. But it is also "a question of what words mean in the English language as this language currently exists," like you stated. Flyer22 (talk) 16:12, 28 January 2013 (UTC)

I fail to see how you can be so ignorant on a topic that requires common sense to understand, a hazelnut is not green and brown however green and brown eyes in certain lightings can look abit gold like a hazelnut so therefore if North Americans have established hazel eyes being green and brown it is called a misconception considering in Europe (the origin of light eyes) the true meaning still exists and a European from Europe would find green and brown being called hazel (resembling the colour of a hazelnut) quite comical. I don't understand how you don't get that and would rather feed people the North American miconcieved meaning instead of the true European meaning.

Ok so i've done abit of research and i've come across five websites that state true hazel eyes being a light brown/gold colour resembling a hazelnut; http://dictionary.reference.com/browse/hazel (defines it as a light golden brown colour, after a hazelnut), http://www.wonderquest.com/eye-color-age.htm (states hazel eyes are light brown or yellowish brown), http://www.fanteye.com/extimages/p_FreshlooksColorblendsChartLG.jpg (shows a pure hazel eye, big difference to the green eye diagonally below to the right), http://www.colormecontacts.com/colored-contacts-for-dark-eyes (puts hazel eyes in the same category as honey, not green plus shows a green eye with abit of brown under the green category), http://www.yestheyrefake.net/color_contacts_buy_photos.htm (shows hazel eyes in numerous pictures and showing them as a golden brown). I have provided you with enough reliable sources there for you to now edit the hazel eyes section and provide people with the true/original European meaning of hazel eyes resembling a hazelnut, and stating the North American modern misconception of hazel eyes being green and brown or any multicoloured iris. — Preceding unsigned comment added by 110.174.147.166 (talk) 14:49, 7 February 2013 (UTC)

How we choose to describe the results of research
Reference #10 does contains the phrase "The genetics of eye color are so complex that almost any parent-child combination of eye colors can occur", which is a wild overstatement. It should not be repeated in the text as a fact. References #9 and 11 seem to me to be reliable, and the text should be adjusted accordingly.

Also, I note with doubt the use of the term "polygenic". This has a long history of use in connection with continuous variable quantitative characters, and seems rather out of place. If we can say "SNPs at two loci cause most of the inherited variation in iris colour" then that is what we should say. Macdonald-ross (talk) 10:11, 27 February 2013 (UTC)

Red Eyes
The label on the picture in this section reads "Red" albino eyes" when it should really read "Red-eye effect".Trisped (talk) 20:19, 10 April 2013 (UTC)
 * The section discusses how the eyes of albino people can appear red, but it doesn't lump that together with the red-eye effect. The red appearance of the eyes in that picture doesn't seem to be from the red-eye effect, at least not solely from it. For one, there's more than a reddish color showing. Contrast it to the picture of the human in the Red-eye effect article, or other pictures of the red-eye effect on the Internet. The image's description also doesn't identify the red appearance of the eyes as being due to the red-eye effect. Flyer22 (talk) 20:41, 10 April 2013 (UTC)


 * Further down on the image's page, you can also see where User:Dark,green.magician took some of the red away, and User:Kersti Nebelsiek stated, "the red was not a fault." The image comes from this source on PubMed; beside Figure 2, it states, "Eyes from a patient with OCA1A. Note that the irises are almost pink, and fully translucent."

Hazel Eye Pictures
i'd like to point out the pictures given as an example of hazel eyes both don't resemble a golden light brown hazel eye colour, the picture on the left is a picture of someone with green eyes that contain central heterochromia (forest green, can be mistaken for amber in certain lightings/angles) and the picture on the right is of someone with blue eyes that contain central heterochromia (can be mistaken for green in certain lightings/angles). I propose the following pictures be shown as a perfect example of what true hazel eyes are;

 * Hazel eyes are due to a combination of Rayleigh scattering and a moderate amount of melanin in the iris' anterior border layer.[4][28] Hazel eyes often appear to shift in color from a brown to a green. Although hazel mostly consists of brown and green, the dominant color in the eye can either be brown/gold or green. This is how many people mistake hazel eyes to be amber and vice versa.[53][54][55][56][57][58][59] This can sometimes produce a multicolored iris, i.e., an eye that is light brown/amber near the pupil and charcoal or dark green on the outer part of the iris (or vice versa) when observed in sunlight.


 * This is the current description of hazel eyes in the article. I think the current photos match that rather well.
 * --TheSonoran (talk) 03:13, 9 April 2013 (UTC)

I disagree as first of all that description of hazel eyes states green can be the dominant colour which is wrong as a hazelnut shell contains no green whatsoever, true hazel eyes are a light honey brown colour matching the colour of a hazelnut shell and in some instances can have a slight hint of green when observed in sunlight or when direct light hits it, it is most certainly is not an eye where green is the dominant colour or a light green colour is prominant. Secondly that description says nothing about hazel eyes being blue in any way so why does the picture on the right strike me as an obvious blue eye with brown around the pupil (central heterochromia), get your facts right.

Excuse me i've made a valid statement and i have not had any response in over a week, the hazel eye pictures need to be changed — Preceding unsigned comment added by 110.174.147.166 (talk) 04:06, 16 April 2013 (UTC)

Eye color chart correction
I edited the text of the "Martin-Schultz" chart, in that it is inverted from Coon's reevaluation of the original Martin Scale. IOW, the Martin's original scale went from blue = 16, Brown = 1 ; (Coon and) Martin-Schultz Scale is ascending in magnitude based on increasing pigment amount: Blue = 1 to Brown = 16 (see wiki on Martin-Schultz to verify) Art4med (talk) 21:51, 30 April 2013 (UTC)

Hazel Eye Picture On The Right
The picture on the right hand side of the hazel eye section does not match the description of hazel eyes, as it is blue with central heterochromia (brown around the pupil). The hazel eye description says nothing about hazel eyes being blue in any way, so i trust this is a mistake that needs to be changed immediately, i propose one of the following pictures be shown in it's place as they match a golden light brown hazelnut colour:

Hazel Eye Myth
The description of hazel eyes says they're green and brown (either colour could be dominant) and can also contain gold, this description is incorrect, true hazel eyes are a golden honey brown colour (basically light brown) which matches the colour of a golden brown hazelnut shell (hence the word hazel), however in some instances can contain minimal amounts of green (either on the outskirts and/or mixed in with the gold) when observed in direct/sun light, but green is by no means a requirement for true hazel eyes.

The myth of hazel eyes being green and brown or any multi-coloured eye is common in North America aswell as areas of the world that have been exposed to Americanisation, However in Europe (the origin of light eyes & hazelnuts) the correct meaning still exists and is used when identifying eye color (hazel eyes = golden light brown colour). The myth of hazel eyes being green and brown or any multi-coloured eye is likely to of started due to green and brown eyes turning a gold and/or light brown colour in areas of dim lighting and actual hazel eyes sometimes presenting slight green when observed in direct/sun light, but this is nonetheless an obvious misconception which requires common sense to understand.

As for green and brown eyes they're well green eyes that contain contain central heterochromia (brown around the pupil) but this does not change the fact of their true colour being the outer green, if you want to categorise them differently the name Forest Green proves worthy or just simply green eyes with brown.

Here are some examples of what true hazel eyes are;

I'm going to agree with you that there are too many distinctions and that grey eyes are a form of blue and amber eyes are the lightest shade of brown however your theory of blue, green, hazel and brown being enough is incorrect as true hazel eyes are just simply a light golden brown (slightly darker than amber) and the definition you've given hazel eyes (green and brown) makes them fall under the green category. So I say there are only 3 true eye colors; blue, green and brown, the rest are significantly different shades/mixes of the 3. — Preceding unsigned comment added by 110.174.147.166 (talk) 16:43, 4 September 2013 (UTC)

True Hazel Eyes
The definition you've given hazel eyes is feeding people with the myth that hazel eyes can present prominent green colouring and be an eye that's just multi-coloured when in actual fact they're eyes that are either a golden/yellow-ish and/or red-ish brown colour resembling the appearance of a hazelnut, which is exactly what the colour 'hazel' is. In terms of eyes it is true green-ish colouration can be present when observed in strong lighting as slight greenness is used to create the golden tones throughout the brown eye in order to produce the hazel colour, however the green is very minimal and not a requirement. The very first reference to eyes being described as the colour hazel was made by Shakespeare in which he was referring to the red-ish brown colour of a ripe hazelnut;

Mercutio: “Thou wilt quarrel with a man for cracking nuts, having no other reason but because thou hast hazel eyes;–what eye but such an eye would spy out such a quarrel?” Act 3. Scene I Romeo and Juliet Source: http://blog.wordnik.com/shakespeare-soup

Now for some reason theres a modern misconception quite common in North American (which is believed to be the origin of the myth) that hazel eyes are any eye that's green and brown (either colour can be dominant) or any eye that's multi coloured (blue, grey or green with brown around the pupil), this doesn't make sense as a hazelnut doesn't present any blue, grey or green colouration and the definition of the colour 'hazel' isn't described as presenting any of those colours either. So even if people 'think' hazel eyes are eyes that contain green and brown or multi-coloured tones, I think the information in the hazel eye section should list the true meaning as it's primary paragraph instead of listing it as one sentence at the end, and then stating that hazel is now commonly used do describe eyes that contain green, gold and/or brown tones as well as any eye that is multi-coloured mainly in North American and that in Europe the origin of light eyes and the colour hazel as well as hazelnuts; the true/original meaning is still used. — Preceding unsigned comment added by 110.174.147.166 (talk) 04:32, 12 November 2013 (UTC)

Current 'Hazel' eye color picture is not hazel.
The in the beginning of the article is not what it claims to be. Hazel eye is described as a predominantly BROWN color, with minimal green around the eye, and at certain light it can look pretty green too. But for the most part it is rather brown, or at least 50% brown and 50% green. THIS picture does not show anything brown at all in the iris, apart from some microscopic spots maybe. The current eye color picture is predominantly GREEN. Seriously, who the hell is managing this article?

My thoughts exactly whoevers in charge of the eye color article is an idiot. I've tried numerous times to inform them that hazel eyes are not green and brown and that it's a north american misconception. Hazel eyes are light golden and/or reddish brown resembling the colour of a hazelnut hence the word hazel, they can contain minimal green within the golden colouration however it is usually very minimal, only present in strong lighting & from good distance but by no means a requirement. It's an issue that requires common sense to understand, but for some reason Wikipedia cannot process my argument because theres no hardcore 'sources', I apologize if no ones ever done a full on research project tracing back to how the hazel eye meaning started shifting in North America. — Preceding unsigned comment added by 110.174.147.166 (talk) 02:49, 27 December 2013 (UTC)

Hazel?
I think the hazel eye section is inaccurate, hazel eyes are just light brown and can be reddish or yellowish matching the colour of a hazelnut, green and brown being hazel is a myth common in the USA. I've noticed people trying numerous times on this talk page to get the hazel eye section edited to give the true meaning a primary paragraph rather than a simple scentence stating that it is sometimes considered synonymous with light brown or gold, why do you keep ignoring them? it's obvious the colour hazel is suppose to represent the colour of a hazelnut not green and brown, I think this article should state what hazel truly means and then state that hazel definitions vary especially in the USA to being green and brown or any multi-coloured iris that shifts in colour which is a misconception.

Notice that IP 27.32.52.200 stated, "I've noticed people trying numerous times on this talk page to get the hazel eye section edited to give the true meaning a primary paragraph rather than a simple scentence stating that it is sometimes considered synonymous with light brown or gold, why do you keep ignoring them?" See anything similar in those arguments, such as use of the wording "I've tried numerous times" and "people trying numerous times"? See anything similar with regard to your spelling, your bad spelling and use of the wording "multi-coloured"? You are IP 27.32.52.200, an IP that was not used since 2010...until this year to make the same arguments you have been making over and over again on this talk page, against Wikipedia policies and guidelines.


 * Oh, and get it through your head already that repeatedly insulting me, name-calling and such, does not do a thing to hurt me. What it mostly does is amuse me that you feel that you have to resort to such "tactics." It also keeps getting your persistent self blocked.

You are incredibly pathetic, a person who has a completely different IP address to me uses one or two words in their vocabulary that I have in my arguments causes you to automatically assume it's me pretending to be someone else as if I have nothing better to do, i'll point out they said they had read my arguments which could have prompted them to use similar words. Why don't you stop being stubborn and accept that hazel isn't what you're telling people it is and I'm not the only one who's picking up on it. Hazelnuts are native to Europe, North America was colonized by Europeans, The first reference to eyes being referred to as hazel was by Shakespeare (a European) where he was referring to a reddish brown colour of a ripe hazelnut, if you go to Europe they will use the term correctly and identify eyes that are light brown with admixtures of golden and reddish tones as hazel. Now why the hell are you giving the true/original European meaning one sentence at the end of the paragraph and giving the north American misconceived ridiculous meaning a large paragraph, if you were to go to North America people will class green and brown, blue and brown, grey and brown or any multi coloured light eye as hazel, they've just distorted the word hazel to basically any eye that has more than one obvious colour in it, so you might as well put that in the definition. Your page is being extremely bias, just because Wikipedia started in America and most of the sites admins are American, you prefer to give your pathetic meaning a large paragraph and the actual/true meaning a small line at the bottom. The hazel section should say hazel eyes are eyes that resemble a hazelnut (light honey and/or reddish brown) and Shakespeare was the first person to refer to eyes as hazel etc etc, and then state that hazel eye definitions vary and have been distorted/misconceived in different regions particularly in North America where many would class green and brown/gold or any multi coloured iris as hazel.

You are sitting here arguing that you are not that person, when anyone with half a brain can see that you are. And yet you call me pathetic? Well, I don't care. Like I stated, "get it through your head already that repeatedly insulting me, name-calling and such, does not do a thing to hurt me.

Poor Description
Hazel is not green and brown or a combination of colours, only idiots will say it is and argue that point, hazel is brown with tones of gold and red throughout, sometimes minimal amounts of green can be present but they can't be too obvious and green is never an actual requirement for the colour hazel as a hazelnut contains no green whatsoever. So why does your description say hazel is a combination of brown, green and gold and either colour could be dominant? i've never seen a hazelnut thats green in any way shape or form, and the line at the end which states; "hazel is sometimes considered synonymous with light brown or gold as in the colour of a hazelnut", what do you mean sometimes? it is always considered synonymous with light brown as that is what the colour hazel is, the only people who use it for eyes with combined colours are either ignorant or uneducated on the matter. why are you giving a ridiculous meaning of hazel eyes when you could look up any website with colour definitions which would state hazel is a light yellowish or reddish brown as in the colour of the nut, who writes this stuff, like seriously? — Preceding unsigned comment added by 110.174.147.166 (talk) 08:06, 16 June 2014 (UTC)

Adding unsourced material
, I clearly reverted you here, here and here. Judging by the warnings on your user talk page, you know how you are supposed to conduct yourself on Wikipedia. Having to revert you three times, when you know why I reverted you (an absence of WP:Reliable sources provided to support your additions), is ridiculous. If you continue to add unsourced material and WP:Synthesis to the Eye color article, and continue WP:Edit warring to keep that unsourced material in, then I will contact the administrator who blocked you before and then take the matter from there. Flyer22 (talk) 08:17, 9 August 2014 (UTC)


 * OK, I will add these information all with sources from anthropological books and publications consisting of medical data. Dont worry. I will do it soon. However you must stop supporting repetitions by repeating the same things twice in this article. It's unnecessary. Yatzhek (talk) 11:40, 9 August 2014 (UTC)


 * , I was not supporting repetitions; I was focused on reverting your unsourced additions. Regarding repetition, I saw that after I reverted you here, you meant the bit about uveitis and uveal melanoma, as seen by your edit here and here. But take notice that uveitis and uveal melanoma are not the same thing. Your edit removed focus on uveitis regarding gray eyes. You also amended the "An increased risk of uveal melanoma" regarding "blue, green or gray iris color" to "and to some extent also in those of green or gray iris color." Unless the source states "to some extent" regarding those eye colors, you should not have added that. I will go ahead and add back the uveitis bit and remove your amending text. And it would be best that the sources you provid are in English and have a URL so that they can be easily assessed and their verifiability (whether they support your content) can be easily proven.

This page is complete nonsense
Blue/green/gray eyes are a genetic disorder. They don't work properly. If you understood how an eye works, you'd probably realize that. No other animals in nature have blue/green eyes for that reason.. Also, people with brown eyes aren't more at risk for cataracts. Just another lie to make people think blue eyes are somehow normal I guess. — Preceding unsigned comment added by Cavefish777 (talk • contribs) 00:42, 21 September 2014 (UTC)

I couldn't agree more, they ridicule and ignore people's suggestions if they don't agree with them, so what's the point of having a talk page in the first place, honestly the administrators in this site are all very arrogant and headstrong. — Preceding unsigned comment added by 110.174.147.166 (talk) 05:18, 29 September 2014 (UTC)

For one, there are some animals that have blue eyes in nature. Second, is the white fur of a polar bear a genetic disorder? How about human white skin? In a low light environment, such as the frozen north, vitamin D synthesis is promoted by light colored skin. People wear clothes in cold environments, which mitigates ultraviolet damage. I have blue eyes, and they work well.66.64.72.10 (talk) 16:45, 7 October 2014 (UTC)

Is this confusing?
Excerpt #1: Eye color is an inherited trait influenced by more than one gene [...]

Excerpt #2: Eiberg and colleagues showed in a study published in Human Genetics that a mutation in the 86th intron of the HERC2 gene [...] reduced expression of OCA2 with subsequent reduction in melanin production.[37] [...] Eiberg stated, "A genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a 'switch,' which literally 'turned off' the ability to produce brown eyes."

In the latter case does only one gene cause blue eyes? It seems contradictory with respect to the first case. Dynasteria (talk) 03:58, 5 December 2014 (UTC)

Also, is this man's research peer-reviewed? He has basically the equivalent of a masters degree according to the Wikipedia article on him. It is a serious disservice to the public to have someone with only a masters degree be the entire basis for a Wikipedia statement on a scientific subject. I will delete the section on his research in due time if no one replies. Dynasteria (talk) 19:17, 6 December 2014 (UTC)


 * Dynasteria, I don't understand your "masters degree" argument. Eiberg is a scholar/researcher, and to see how much traction his scholarly work has gotten, you can simply look into the matter on Google Books or on Google Scholar. Yes, his work has gotten news attention, but we need to see about the scholarly attention it has gotten. Flyer22 (talk) 19:24, 6 December 2014 (UTC)


 * Google Books and Google Scholar link to the Wikipedia article on Hans Eiberg and nothing else. The Wikipedia article has two external links, one of which does not function, the other of which is Eiberg's personal website. In addition, footnote #36 is to an MSNBC "news" article. Really? So now Wikipedia is putting out "credible" information based on what a reporter says?


 * Footnote #37 links to this scholarly article which says the following in its abstract:


 * The human eye color is a quantitative trait displaying multifactorial inheritance. Several studies have shown that the OCA2 locus is the major contributor to the human eye color variation. By linkage analysis of a large Danish family, we finemapped the blue eye color locus to a 166 Kbp region within the HERC2 gene. By association analyses, we identified two SNPs within this region that were perfectly associated with the blue and brown eye colors: rs12913832 and rs1129038. Of these, rs12913832 is located 21.152 bp upstream from the OCA2 promoter in a highly conserved sequence in intron 86 of HERC2. The brown eye color allele of rs12913832 is highly conserved throughout a number of species. As shown by a Luciferase assays in cell cultures, the element significantly reduces the activity of the OCA2 promoter and electrophoretic mobility shift assays demonstrate that the two alleles bind different subsets of nuclear extracts. One single haplotype, represented by six polymorphic SNPs covering half of the 3′ end of the HERC2 gene, was found in 155 blue-eyed individuals from Denmark, and in 5 and 2 blue-eyed individuals from Turkey and Jordan, respectively. Hence, our data suggest a common founder mutation in an OCA2 inhibiting regulatory element as the cause of blue eye color in humans. In addition, an LOD score of Z = 4.21 between hair color and D14S72 was obtained in the large family, indicating that RABGGTA is a candidate gene for hair color.


 * Note the use of the words "multifactorial" as well as "major contributor" (not "sole contributor") which would indicate that it is not one gene only that causes this phenomenon. Also, there is no mention of this genetic shift occurring 8-10 thousand years ago. I am very curious to find out when this shift may have occurred, but it seems Mr. Eiberg does not reliably supply this information. Dynasteria (talk) 17:11, 7 December 2014 (UTC)


 * Do you want to ask about this matter at the WikiProjects currently at the top of the talk page, and/or at WikiProject Biology? Flyer22 (talk) 18:04, 7 December 2014 (UTC)


 * Thank you for your suggestion. I don't know where those links lead to. I have asked a question here and anyone who wants to join in is more than welcome. I thought that was the purpose of the Talk page. I wonder sometimes about Wikipedia's reliance on experts such as Mr. Eiberg instead of on people's knowledge out in the community.
 * I also frankly don't understand Wikipedia's use of indents in conversations like this where you would in very short time have your words be narrowed down to


 * an extremely constricted space. Dynasteria (talk) 18:36, 7 December 2014 (UTC)


 * That's a joke, of course. I did try to post a question on User Biology right now but it didn't work. I think I should have done it on the Talk page. Will try again later.Dynasteria (talk) 18:55, 7 December 2014 (UTC)


 * Some talk pages are low in traffic; this is one of those in some ways. By that, I mean that this talk page does not receive a lot of attention. In such cases, asking for comments beyond the talk page is often better. WP:WikiProjects are a part of that purpose. So are WP:Dispute resolution matters. Regarding the post you made, that should be at that WikiProject's talk page, not on its main page. As for experts vs. "people's knowledge out in the community," I'm not quite sure what you mean, but we should go by the WP:Reliable sources. And for science topics, there are some sourcing rules; for example, WP:Fringe or WP:MEDRS. Flyer22 (talk) 19:08, 7 December 2014 (UTC)


 * I should have said: reliance on single experts vs. a broader range of people in the scientific community. I may be wrong, but I noticed in the mid 2000s that Jared Diamond was cropping up all over the place as the last word on anthropology. He's not, because there is no such thing as the last word in the hard sciences, much less the soft sciences. I mean, I like Jared Diamond's writing and I agree with him a whole lot. I just think there should be more than one viewpoint put forth.


 * I'll work on navigating the other talk pages. Dynasteria (talk) 01:52, 9 December 2014 (UTC)

New interpretation needed
The following is the next to last section in the Hans Eiberg article linked in footnote #38, which is discussed in the Blue section of this Wikipedia article:


 * The origin of the founder mutation


 * The mutations responsible for the blue eye color most likely originate from the neareast area or northwest part of the Black Sea region, where the great agriculture migration to the northern part of Europe took place in the Neolithic periods about 6–10,000 years ago (Cavalli-Sforza et al. 1994).


 * The high frequency of blue-eyed individuals in the Scandinavia and Baltic areas indicates a positive selection for this phenotype (Cavalli-Sforza et al. 1994; Myant et al. 1997). Several theories has been suggested to explain the evolutionary selection for pigmentation traits which include UV expositor causing skin cancer, vitamin D deficiency, and also sexual selection has been mentioned. Natural selection as suggested here makes it difficult to calculate the age of the mutation.

Note it does not say "when" or "at the time that" but instead says "where" in the first paragraph. Note the last sentence in the last paragraph. It states rather unambiguously that the age of the mutation is difficult to calculate. The following sentence from the Wikipedia article Blue section appears to be false or highly misinformed: "The authors suggested that the mutation may have arisen in a single individual living in the northwestern part of the Black Sea region during the Neolithic revolution.[37][38]"

There are news articles and bloggers saying that a single individual who lived 8,000 years ago is the sole ancestor of the trait in all blue eyed people, which seems patently ludicrous. I'm going to spend some time working on changing this article. Input from others would be most valuable. Dynasteria (talk) 00:31, 10 December 2014 (UTC)

Article inaccuracies - Albinism
Section: Genetic determination

"The gene OCA2 (OMIM: 203200), when in a variant form, causes the pink eye color and hypopigmentation common in human albinism."

Incorrect, actually red eyes is rare and not common in human Albinism as implied in this section, however a strong red eye effect will usually occur during flash photography -http://www.albinism.org/publications/what_is_albinism.html

Section: Anomalous conditions

"Normally, there is a thick layer of melanin on the back of the iris. Even people with the lightest blue eyes, with no melanin on the front of the iris at all, have dark brown coloration on the back of it, to prevent light from scattering around inside the eye. In those with milder forms of albinism, the color of the iris is typically blue but can vary from blue to brown. In severe forms of albinism, there is no pigment on the back of the iris, and light from inside the eye can pass through the iris to the front. In these cases, the only color seen is the red from the hemoglobin of the blood in the capillaries of the iris. Such albinos have pink eyes..."

Again this section implies more strongly than is accurate red eyes is common amongst humans with albinism it should more read the average human with albinism has blue eyes but some with severe albinism may have violet or red eyes, although the term severe is also a bit of a misnomer. -http://www.albinism.org/publications/what_is_albinism.html 12.14am (talk) 06:14, 16 December 2014 (UTC)

Blue eyes are commonest in Northern Europe, in the British Isles, Scandinavia and the Baltic States. In these countries, over 67% have blue and green eyes. For example in Estonia, Denmark, Norway over 80% have blue and green eyes, in the British, 78% have light eyes, especially blue, in Germany very slightly less people at 75%. For pure blue eyes Ireland, Norway, Sweden are similar all around 50%. — Preceding unsigned comment added by Mishee2000 (talk • contribs) 06:42, 24 December 2014 (UTC)

It's absolutely false that anywhere in north Africa or in middle east (perhaps with the exception of some areas in Israel) can be a % of light eyes higher than in Spain, Italy, Romania and Bulgaria.

Morocco 20/49 % light eyes? Lol, I've been in Morocco 4 times, I can say I never met a native with grey, blue or green eyes, and I think anyone who visited Morocco can agree with me, almost all the people have black or dark brown eyes as it happens among the other arabs, maghrebians, kabyles, riffians and anyone else lives in North Africa. Only very very very few people have hazel eyes, which are even not considered light eyes. — Preceding unsigned comment added by 78.12.210.141 (talk) 17:34, 25 December 2014 (UTC)

Neolithic Revolution and date of the "blue eye mutation"
In this edit, ‎Evanh2008 removed mention of the Neolithic Revolution, stating, "The Neolithic Revolution was a worldwide event, not a local one." I changed the wording, stating, "Then tweak it. Not giving any kind of date is too vague." Evanh2008 reverted me, stating, "Then the problem is with the sources; they give no date."

Actually, the sources do give a date. This one states, "The mutation occurred between 6,000 and 10,000 years ago, so before then, there were no blue eyes." This one is a WP:PAYWALL source, and I don't think that Evanh2008 read that one beyond the abstract. And this one states, "Frank Sinatra, Stephen Hawking, Marie Curie and Stephen Fry all owe their blue eyes to a genetic mutation that likely occurred between 6,000 and 10,000 years ago, researchers say. ... Blue eye colour most likely originated from the near east area or northwest part of the Black Sea region, where the great agriculture migration to the northern part of Europe took place in the Neolithic periods about six–10,000 years ago." The article used to state "6,000–10,000 years ago," but, Dynasteria removed it. For other comments from Dynasteria, see the section above. Flyer22 (talk) 06:04, 4 January 2015 (UTC)

And like I just stated in this WP:Dummy edit, my point (for adding the Neolithic Revolution link back) was that the Neolithic Revolution link gives some type of time frame. Flyer22 (talk) 06:10, 4 January 2015 (UTC)
 * Please don't make assumptions about which sources I've read. I have access to the paywalled source on the ProQuest database via a university subscription. You are certainly correct that I was wrong in saying that the sources don't give a date&mdash;I read the paper and, my reading comprehension academically blunted, skimmed through the other two. While skimming I saw the last of the quotations you gave, describing the Black Sea (for some reason) in terms of the date at which agriculture developed there. Poor choice on the part of the writers, but poor attention-paying on my part as well. The paper does the same thing, unfortunately, and without even the benefit of giving even a cursory guess at an actual date for the mutation. They could have just as easily described the Black Sea region as the site of the Crimean War in the mid 19th century; it's unclear in the context of the article why they chose to give that date, and I now wonder if that choice has resulted in confusion on the part of the secondary sources.
 * My point, basically, is that I find no support for a Neolithic date in the primary source&mdash;that's why I reverted you&mdash;and what support I now see in the secondary sources looks worryingly like a misreading of the paper. Evan (talk&#124;contribs) 06:36, 4 January 2015 (UTC)


 * For the record, this is the relevant extract from the paper:"The mutations responsible for the blue eye color most likely originate from the neareast area or northwest part of the Black Sea region, where the great agriculture migration to the northern part of Europe took place in the Neolithic periods about 6–10,000 years ago (Cavalli-Sforza et al. 1994)."Which is paraphrased by The Telegraph in the fourth paragraph of the article. I'll try to track down the Cavalli-Sforza article tomorrow. Evan (talk&#124;contribs) 06:40, 4 January 2015 (UTC)


 * Thanks for explaining, Evanh2008. As for the WP:PAYWALL comment, I was speaking from experience; by that, I mean that editors usually don't have access to whatever paywall source in question, or they have limited access to it. Regarding the sourcing issue, it seems like a Identifying reliable sources issue, an aspect that I also mentioned in the section immediately above this one. Flyer22 (talk) 06:43, 4 January 2015 (UTC)
 * Flyer22 - Cavalli-Sforza turned out to be a book. I managed to get my hands on an abridged version of the book, but couldn't for the life of me track down any mention of eye color and the Black Sea (the paywalled article wasn't kind enough to give a page number). If someone wants to restore the Black Sea datum to the article, I'm not dedicated enough to revert it, though I still think the evidence is shaky, unless someone can check the Cavalli-Sforza source and verify.

Rayleigh vs. Tyndall
The Tyndall effect article claims that the Tyndall effect is the source of color (at least, for blue irises). The Eye color lede says that "The appearance of blue and green, as well as hazel eyes, results from the Rayleigh scattering of light in the stroma", and this also has a cited source. 93 01:28, 4 March 2015 (UTC)

Eye color chart (Martin Scale) section
The "Eye color chart (Martin Scale)" section is, presumably, a relic of earlier anthropological writing. However, this is no excuse for scientific disinformation being included. The section mentions "brown pigment" and, "light pigment". There is only one pigment involved in iris colour and that is melanin - which can appear brown or black depending on concentration. The various colours found in the human iris are the result of optical effects due to muscle layering interacting with greater or lesser amounts of melanin.

 * Since limbal ring is reduced by 55% on average by immersion in water (http://www.ncbi.nlm.nih.gov/pubmed/19648842), it is quite likely that natural eye moisture changes can affect light scattering/interference-induced aspect of eye colour. --Bstard12 (talk) 23:38, 24 May 2015 (UTC)

"Blue eyes are rare in mammals "
Point 1. Surely this is demonstrably untrue? Lots of cats have blue eyes. Quite a few humans have blue eyes. Some dogs have blue eyes. Any one of these counterexamples makes the sentence untrue.

Point 2. To go off at a tangent, there is a reasonably common mutation in alpacas whereby male alpacas with blue eyes are almost always deaf. This is regarded as a deleterious mutation, since hearing in alpacas - whether wild or farmed - is extremely important. I don't have a reference for this, but I dare say any national alpacas association can probably provide something. 124.176.105.121 (talk) 07:37, 27 April 2015 (UTC)
 * I disagree with that first part. I'm not sure about the specific wording, but blue eyes are not particularly common, and citing a couple of examples does not disprove a claim. The best action you can take on your part is to attempt to find reliable sources supporting your claim and bring them here. Dustin  ( talk ) 19:05, 28 May 2015 (UTC)

Contradiction in this sentence
"The majority of people in the world overall have dark brown eyes. Dark brown is often found in the Semitic people, among Jewish and Arab populations in the Middle East."

According to whom and where is the proof? This sentence also contradicts itself implying majority of the people in the world have dark brown eyes and then proceeds to say it is the most common among semites. So i think the last sentence is really pointless since Arabs and Jews also fall under the category of the majority. Not to mention no citations are given for the afromentioned.
