The gene that causes lighter skin pigmentation, SLC24A5, was introduced from eastern African to southern African populations just 2,000 years ago. Strong positive selection caused this gene to rise in ...

A gene controlling our biological clocks plays a vital role in regulating human-specific genes important to brain evolution. These findings open new paths of research into how CLOCK proteins produced ...

A new analysis of lice genetic diversity suggests that lice came to the Americas twice – once during the first wave of human migration across the Bering Strait, and again during European colonization.

In two studies, researchers demonstrate how climate modeling approaches can fill gaps in our understanding of hominin evolution and migration. Over the last several decades, research efforts into the ...
