Known as the Cambrian Explosion, this flurry of rapid evolution produced most of the animal phyla and ecosystems we see around us today. And it may have taken off because some of those early animals ...

Humans have become one of the world's greatest evolutionary forces. To survive our cities, animals from urban foxes to glass-climbing lizards are responding with extreme adaptation.

Fossilized feces may have helped fuel the Cambrian Explosion by moving nutrients and organic matter through ancient oceans as ...

A hidden force let humans smash a barrier that had trapped our ancestors for millions of years.

In most narratives, the story of evolution is the story of organisms emerging from the ocean and eventually populating the land. But for some species, that evolution also involved a return trip.

Keeping pets seems to be fairly recent behaviour in the timeline of human evolution. Columnist Michael Marshall turns to the ...

A series of whole genome and gene duplication events that go back hundreds of millions of years have laid the foundations for tissue-specific gene expression, according to a new study. The 'copy-paste ...

Biologists from Stockholm University and University of Neuchâtel present groundbreaking research shedding new light on the evolution of social bonds and cooperation among group-living animals. The ...

In five cases where vertebrates evolved monogamy, the same changes in gene expression occurred each time. In many non-monogamous species, females provide all or most of the offspring care. In ...

To understand the origins of multicelled life, researchers are studying a motley assortment of simpler animal relatives. The commonalities they’re unearthing offer a trove of clues about our mutual ...
