Human evolution is not a straight line but a complex branching tree shared with other great apes. This overview explains the ...

Human evolution’s biggest mystery, which emerged 15 years ago from a 60,000-year-old pinkie finger bone, finally started to ...

For decades, the dominant theory in human evolution suggested that modern humans descended from a single ancestral lineage in Africa. However, groundbreaking new research from the University of ...

Humans were living in rainforests roughly 150,000 years ago, some 80,000 years earlier than was previously thought—and may have been an important center for early human evolution. This is the ...

Fossils unearthed in Ethiopia are reshaping our view of human evolution. Instead of a straight march from ape-like ancestors to modern humans, researchers now see a tangled, branching tree with ...

Four lifelike reconstructions of prehistoric humans have been unveiled — including a model of a species often dubbed "the hobbit," which, as an adult, was about the same height as a modern 4-year-old.

Scientists have uncovered new evidence suggesting that autism may have it roots in how the human brain has evolved. "Our results suggest that some of the same genetic changes that make the human brain ...

Autism spectrum disorder (ASD) may be the result of millions of years of evolution. Rapid neuronal evolution in humans is likely ASD’s genetic cause, new research suggests. Though autism can cause ...

Scientists say they have solved the mystery of the Burtele foot, a set of 3.4 million-year-old bones found in Ethiopia in 2009. The fossils, along with others unearthed more recently, have now been ...

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 ...
