Researchers have discovered key insights into the molecular basis of skin color variations among African populations. Their findings broaden the understanding of human evolution and the genetics ...

Then, they undertook a detailed analysis of the NASA UV data and published measurements of human skin color variations around the world, which had been collected by anthropologists over many decades.

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 causes different ...

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 ...

During the course of human evolution ... quite a bit of variation within the continents. So it doesn't make sense to equate such large regions of the world to a particular skin color.

Understanding the genetics of variation in human traits has been a long-standing ... left 135 that were not previously associated with skin color in other studies. “We hypothesized that if ...

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.
