Ancient, fossilized teeth, uncovered during a decades-long archaeology project in northeastern Ethiopia, indicate that two different kinds of hominins, or human ancestors, lived in the same place ...

On Valentine’s Day in 2018, a team of scientists walked across a flat expanse in the badlands of northeastern Ethiopia, scanning the ground for fossils. An eagle-eyed field assistant, Omar Abdulla, ...

He extracts several predictions, including the acceleration of recent evolutionary trends toward smaller brains, selection on attention spans, personality types, and mood-disorder susceptibilities. He ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

Researchers say recently discovered teeth come from a previously undiscovered species of Australopithecus, adding to our understanding of human evolution. Maybe you've seen the T-shirts or the mugs, ...

A paper in Molecular Biology and Evolution finds that the relatively high rate of autism-spectrum disorders in humans is likely due to how humans evolved in the past. The paper is titled "A general ...

Researchers discovered that autism’s prevalence may be linked to human brain evolution. Specific neurons in the outer brain evolved rapidly, and autism-linked genes changed under natural selection.

Our brain is arguably the organ that most distinguishes humans from other primates. Its exceptional size, complexity and capabilities far exceed those of any other species on Earth. Yet humans share ...
