The Evolution of Human Skin Pigmentation

Nina Jablonski looks at the evolution of human pigmentation. It was noted by Darwin and others that humans who lived closer to the equator had darker skins. Is this a functional adaptation to sun exposure, or is there something more at play here? Series: "Darwin Evolving" [10/2009] [Science] [Show ID: 16926]

@TheBlackOnWhiteCrime Stereotyping. I have known black people that look like had white features, chinese features..but they were black. If their skin was light they would just look asian or white. How can you not see this? Sure some black people look like the stereotype, but I went to an all black school once and I am white, they do not all look like the stereotype. Everyone has a different nose, skull, ears. IQ? Cultural practices contribute to intelligence. Not pigmentation level.

@ 49:40 snow tan by UBV ( the devolopement of clothing might very well of had play a part in skin pigmentation via as the UBV ray passed threw the clothing made from animal skin etc ) plus In the hot regions of the planet where they would of wore very little to no clothing.. body sweat beading up on the surface of the skin could of create a magnified lens effect as the sun ray entered into the deeper skin layors "Great video topic thanks"

@gethsoftware You need to look deeper and go back much, much further in our evolutionary past. Xenophobia is a built in defense mechanism, just like arachnophobia. And just like arachnophobia it can be overcome, but we need to accept that it is the default mechanism. We are all intolerant of certain groups be they religious,atheist, gay, breeders, socialist, libertarian, etc. I feel the best approach is to accept that fact and work from there and to work for a steady change from everyone.
