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

Learn about the new proposal for the origins of modern humans, suggesting that our species is a genetic combination of two ...

For the first time in humans, researchers have discovered a large chromosomal rearrangement that bears the mark of natural selection, they report in the February issue of Nature Genetics. The ...

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.

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

Today, with access to heretofore unprecedented data sets for the study of human genetic variation, researchers can exploit the genetic signatures of natural selection using novel analytical methods.

Many people are. In fact, the ability to digest lactose may be an example of adaptive evolution in the human lineage. Although the study of natural selection in humans is still in an early stage ...

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

Darwin thought that evolution took place over hundreds or thousands of years and was impossible to witness in a human lifetime ... The Grants had documented natural selection in action.

Intelligent Design on Trial" reveals how genetic evidence helped to confirm an important component of Darwin's theory of evolution by natural selection: the common ancestry of humans and apes.

Natural selection is the process by which some organisms ... Nowadays there is also a new force in evolution: humans. We are exerting new selection pressures on many species, changing them in ...

Humans may not be the only animals that ingest alcohol, research is suggesting. Studies on animals are showing they may be eating natural ethanol for its medicinal or nutritional properties.
