DNA from a Neanderthal bone fragment in Crimea, dated to around 45,900-45,300 years ago, reveals genetic links between European and Siberian Neanderthals and suggests a migration corridor along 55°N.
Geneticist David Reich explains how analyses made possible by technological advances show human history to be one of mixing, movement, and displacement.
New genetic research suggests that humans first developed language around 135,000 years ago, with its widespread social use around 100,000 years ago. This study, using data from 15 genetic studies, indicates that language likely began as a cognitive system before becoming crucial for social communication.
In a recent study by scientists at UC San Francisco, human accelerated regions (HARs) have been identified as crucial to the rapid evolution of human brain complexity, distinguishing us from our closest evolutionary relatives, chimpanzees. These regions, evolving 10 times faster than the typical mammalian rate, enable the formation of intricate neural networks, which support advanced cognitive functions.
