As koalas in southern Australia have grown from a few hundred to almost half a million, the marsupials show signs of regaining lost genetic variation.

Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...

A large international team of anthropologists, evolutionary theorists, biologists, and historians has identified gender and genetic variability via sequencing of enamel proteins from four Paranthropus ...

Fish caught in the same trawl and sold under the same name may in fact have significant genetic differences. Beneath the surface of the Skagerrak lies a biological diversity that is rarely seen in ...

Even a single gene, reshuffled or regulated in new ways, can fuel repeated bursts of evolutionary innovation, according to a recent study of wheatear birds. A study was recently published in the ...
