Scientists say some of the traits that define modern humans may have evolved only after long-standing biological and cultural ...

The uvula is nearly unique to humans among mammals. An evolutionary biologist unpacks competing theories for why we evolved ...

Early human ancestors underwent significant physical transformations over millions of years. New research challenges the idea ...

Two of the traits that set modern humans apart from non-human primates are taller stature and a higher basal metabolic rate. Researchers have identified a genetic variant that contributed to the ...

Researchers at the University of Tsukuba have demonstrated that intensified environmental variability (EV) can promote the evolution of cooperation through simulation based on evolutionary game theory ...

A new analysis suggests the evolution of human body size was marked by a major turning point rather than gradual growth. Credit: Shutterstock. Human body size evolution was shaped ...

For thousands of years, humans have selectively bred dogs to fulfill specific roles, ranging from guarding and hunting to herding and companionship. This deliberate shaping of traits has resulted in ...

While humans and chimpanzees share a common evolutionary history, we will never hear how our ancient ancestors laughed.

Researchers have put forth a theory that humans are no longer subject to natural selection for evolution, but instead that ...
