For decades, paleoanthropologists have debated one of the biggest questions in human evolution: when did our ancestors begin walking on two legs? A groundbreaking new study now offers powerful ...

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...

The skull had the brow of a descendant but the face of an ancestor. When researchers finished reconstructing the DAN5/P1 cranium from Ethiopia’s Afar region, dated to between 1.6 and 1.5 million years ...
