A quiet neighboring species changed how sticklebacks select their mates. Just one new species can alter the path of their ...

Urban environments offer the opportunity to study the role of adaptive and non-adaptive evolutionary processes on an unprecedented scale. While the presence of parallel clines in heritable phenotypic ...

In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...

When Homo sapiens and Neanderthals interbred, a genetic variation affecting red blood cells may have hindered reproduction in ...

The researchers identified regions with Neandertal ancestry in over 300 individuals. They assessed sharing of segments, inferred gene flow, and looked at variation to identify candidates for positive ...

How do cells know what they should become as the body develops? Biological development depends crucially on spatial patterns: the lines that eventually give rise to segments, organs, or markings like ...

Giraffes are a beautiful and powerful example of what adaptive evolution can achieve. However, in recent years they have attained notoriety for a completely different reason: it has been suggested ...
