For centuries, scientists have thought of the brain as a single, unified organ. But new research led by Stanford Medicine reveals that what we call the brain is two distinct organs that evolved independently over hundreds of millions of years.

“These animal models offer a unique opportunity to study how disease-associated alterations in human brain circuitry manifest in an intact nervous system,” said study author Sergiu Pasca

Bipedalism, or walking on two legs, is one of the key features that distinguishes humans from other apes. But when and why our ancestors transitioned from a life often spent in trees to a life spent almost exclusively on the ground remains a subject of debate.

More than 400,000-year-old Homo erectus teeth from China may reveal a surprising link between this ancient human species, Denisovans, and some modern people. Scientists found protein mutations suggesting several East Asian Homo erectus populations belonged to the same evolutionary group,

A new Tel Aviv University study challenges assumptions about the Neanderthal pelvis, finding that modern human males evolved a distinct walking mechanism. Men may want to blame biology for their

The seemingly trivial ability to hear a regular pulse in music is a remarkable—and perhaps distinctively human—feature of the brain. In a wide-ranging critical review, Gábor Háden of the HUN-REN Research Centre for Natural Sciences and Henkjan Honing of the University of Amsterdam evaluate more than two decades of research into how this capacity develops and has evolved.

We aren’t the only humans to have called Earth ‘home’; before us there were dozens of human species and like us they travelled far and
