May 21 (Reuters) - A new fossil of the Cretaceous Period dinosaur Psittacosaurus, a dog-sized herbivore with a parrot-like beak, that was donated to a Chinese university came with a surprise - one ...

Evidence for adaptation of human skin color to regional ultraviolet radiation suggests shared and distinct genetic variants across populations. However, skin color evolution and genetics in East ...

Skin color is highly variable in Africans, but the underlying molecular mechanisms remain poorly understood. Using population genetics and functional genomics, we identified key genetic variants, ...

Researchers from the University of Pennsylvania have discovered key insights into the molecular basis of skin color variations among African populations. Their findings, published in Nature Genetics, ...

The commonly accepted theory of skin color evolution holds that early humans developed lighter skin as they moved away from Africa and into Europe’s northern latitudes. The idea was that lighter skin ...
