Scientists discovered humans descended from two ancient populations, not one. These groups split 1.5 million years ago.

Scientists uncovered a key genetic pathway in the origin of feathers, but they found that evolution is stubborn in turning ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe.

A new study reveals that a mysterious human ancestors contributed 20% of modern human genes, potentially enhancing brain ...

New research has shown that modern humans descend from not one but two separate ancient human ancestral lineages.

Utilizing sophisticated analyses grounded in complete genome sequences, researchers at the University of Cambridge have ...

"Our history is far richer and more complex than we imagined," said human evolutionary geneticist Aylwyn Scally.

Studies have suggested that genes under strong sexual selection tend to evolve rapidly, particularly those associated with ...

Chimpanzees are humans' closest living relatives, sharing more than 98% of our DNA. They are endangered, with fewer than ...

When a gene gets duplicated, it often leads to the recipe being followed too many times, and the resulting “leftovers,” the ...

Lurking within the genomes of nearly all species--including plants, fungi, and even humans--are genes that are passed from generation to generation with no clear benefit to the organism. Called ...

may have played a crucial role in human evolution," said Cousins. The study also found that genes inherited from the second population were often located away from regions of the genome linked to ...
