Hank brings you the facts, as they are understood by scientists today, about the evolution of humans from our humble primate ...

This has been quite the wild year in human evolution stories. Our relatives, living and extinct, got a lot of attention—from new developments in ape cognition to an expanded perspective of a ...

The evolution of the human species is marked by an increase in brain size. Now new research suggests that could be partly ...

The human body is a machine whose many parts – from the microscopic details of our cells to our limbs, eyes, liver and brain – have been assembled in fits and starts over the four billion years of our ...

How did humans become human? Understanding when, where and in what environmental conditions our early ancestors lived is central to solving the puzzle of human evolution. Unfortunately, pinning down a ...

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 ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Researchers have demonstrated that intensified environmental variability (EV) can promote the evolution of cooperation through simulation based on evolutionary game theory. This result offers a new ...

"Consciousness," although challenging to define, can be thought of as a first-person awareness of one's surroundings and oneself. You sense the world through your eyes, nose, ears and hands, and track ...
