I'm going to paraphrase what I heard once.

I had heard that the Negroid nose is wider(flatter?) than the Caucasoid/Europoid thin(pointy?) nose because Negroes had to breathe in more air in their climate or something like that. The Caucasians from the Caucaus mountains didn't have to breathe in that much air because of the freezing climates etc. This could also sum up skin pigmentation (colder/warmer temperatures and adaptability) as Odd Nonposter explained above. Not sure if this is the "end all answer" but I figured I'd just pass along what I had once heard.

Thanks for your answer Jeff777 and everyone else. I really want to understand it. I have always wondered, but haven't asked because I don't want to appear racist in anyway - I have a genuine interest. Do you know why asians have double eyelids?

According to the wikipedia article on the epicanthic fold, the leading theory is protection from wind and glare in extreme environments such as mountains, steppes and deserts.

because your mothers and your fathers had those features. your questions are easy.

but, you see... my question is WHY did they have those features (do not reply that it's because their mother's and father's had those features!).

Wait Asians generally have single eyelids, not double. Double is what the rest of us have. But yeah, that's interesting to think about. That and the differences in eye color among some races... Maybe some of it is just chance?

Technically, it's all chance but I think I know what you mean. In that case, It could be genetic drift or a gene that does something that affects fitness enough to be selected for could randomly do something else, like eye color, as well. A lot of that sort of stuff goes on.

yeah, my mistake. basically, eyelid with a crease = double eyelid - and - without a crease = single. but some asians can still naturally have double...
it actually makes me feel really awful that some eastern women feel pressured into having cosmetic surgery done to have western eyes.

ecuadorian regions get more sun. darker pigmented skin is less susceptible to UV damage.

more northern and southern regions allowed for lighter pigmentation and a more stocky build.

they all facked each other and now we're here.

An Asian woman has the double eyelid surgery and Tyra Banks basically cuts through her BS as to why she had it done and...well it's interesting. O_O
