In other words, a complex variation in skin color has been part of human evolution for a very long time. Another finding is that at least some skin color genes have changed significantly over time.

Few human traits are more variable ... that these variants collectively account for 29 percent of the variation in skin color in the three countries studied. That’s a big proportion!

Human populations feature a broad palette of skin tones. But until now, few genes have been shown to contribute to normal variation in skin color, and these had primarily been discovered through ...

In a recent study, researchers took skin color measurements from local residents in India to quantify the range and extent of variation in ... biological spectrum of human skin color besides ...

Skin color is one of the most obvious and (literally) superficial ways humans differ. But the evolutionary story behind this variation is shared: Over the course of human evolution, complexion evolved ...

Their skin faded as they moved north, because lighter-skinned humans survived Vitamin D deficiency and lived to reproduce. It took many generations to result in the variation of our species.

Although all humans have the same number of melanocytes, the amount of melanin they produce differs and gives rise to the variation in human skin color. To understand what actually causes ...

Previous studies had revealed some genes behind melanocyte maturation and melanin production, but only enough to explain between 23% and 35% of the variation in human skin color, Wysocka and her ...
