Quoted By:

>Considering our species, Homo sapiens, did not evolve until around 200,00 to 300,000 years ago, the discovery suggests that the genes responsible for lighter skin tones were present into the genetic material of our hominin ancestors—hundreds of thousands of years before the first humans walked the Earth.
>Three of the genes associated with the darkest skin are likely to have evolved from genes for lighter skin tones, meaning that people with the darkest skin tones, like herdsmen who live in the Sahara, may have developed that deep pigmentation in the evolutionarily recent past.
>As this study shows, the genes for light skin have been there since the beginning. “If you were to shave a chimp, it has light pigmentation,” Tishkoff says in a press release. “So it makes sense that skin color in the ancestors of modern humans could have been relatively light. It is likely that when we lost the hair covering our bodies and moved from forests to the open savannah, we needed darker skin. Mutations influencing both light and dark skin have continued to evolve in humans, even within the past few thousand years.”
