Humans have become one of the world's greatest evolutionary forces. To survive our cities, animals from urban foxes to ...

Add Yahoo as a preferred source to see more of our stories on Google. Once upon a time, there were a bunch of one-celled microbes, swimming, eating, reproducing, doing all the things that a one-cell ...

A sweeping analysis of thousands of animal genomes suggests that chromosomes do not evolve randomly but instead follow a limited number of irreversible “evolutionary highways.” These one-way genetic ...

By examining thousands of genomes along with fragments of ancient chromosomes, researchers uncovered the intricate journey of ...

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 ...

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.

A microorganism whose evolutionary roots can be traced to the era of the first multicellular animals may provide a glimpse of how single-celled organisms made a critical evolutionary leap. In ...

We often think of microbes as organisms that live around us, like the Salmonella bacteria and flu viruses that cause illness. But some of our most intimate relationships are with the microbes living ...

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 ...

"This book was originally published as an issue of Philosophical transactions of the Royal Society B; Biological sciences (volume 363; number 1496) but has been materially changed and updated"--Title ...

New research suggests ancient feces helped fuel marine life during the Cambrian Explosion.

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 ...
