DailyDirt: Don't Make My Brown Eyes Blue!

from the urls-we-dig-up dept

Eye color isn't a simple single gene trait. In a rare 1% of the population, some people have two different colored eyes or eyes with multiple colors (aka heterochromia iridum). Most people have brown eyes, but it's easy to change your eye color with contact lenses to any color you want -- even scary unnatural monster eyes. Eye color doesn't seem to have much meaning -- as long as you don't teach kids otherwise -- but genetic studies will probably find some interesting correlations in the future. After you've finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

    Melanesians and Aboriginals

    There are a few of both groups that have blonde hair and blue eyes along with dark skin. Neither has the same mutation that gives the rest of the world blue eyes.

    Things that make your brown eyes blue are much better than things that make your blue eyes brown.

    Re: oh, really easy

    One group, surviving a gene mutation, about 6/10 years ago. Sounds familiar, like the event that killed off the majority of the world population, then. Thee blue eye, lighter skin sound like an adaption trait that survived for some reason. Lower light level, different survival tatics needed. What driver for the adaption?

    But what about green and hazel eyes?

    Awesome

    How freakishly awesome it must have been to be the only person on the planet with blue eyes.

    And yes, that person got laid...

    Brown eyes blue

    I have cataracts in my eyes (well, actually an artificial lens in one eye, and a cataract in the other).

    I likely wouldn't have them if my eyes had any protective pigmentation - ie, if my eyes weren't blue.

    Thanks for the read!

    As someone with central heterochromia iridum (and heterochromia of the hair, although that's more subtle), I appreciated the additional information. Whenever someone asks me what colour my eyes are, I just ask them to make a best guess. Upside is that I can change my perceived eye colour by changing my shirt :D

    I have dark blonde/light brown hair and green eyes. My facial hair is black though.

    > common ancestor

    As we were taught not that long ago, blue eyes occured spontaneously among various disparate groups as a result of one of the eye color genes being prone to damage.
