For more than a century, biologists assumed that the bony plates embedded in the skin of lizards – like natural chain mail – ...

This has been quite the wild year in human evolution stories. Our relatives, living and extinct, got a lot of attention—from ...

Songbirds on the UCLA campus changed beak shapes during the pandemic, according to a new study. Researchers suspect it might be a case of rapid evolution.

Jawbones and other remains, similar to specimens found in Europe, were dated to 773,000 years and help close a gap in ...

Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher ...

Fossils unearthed in Morocco are the first from a little-understood period of human evolution and may be remains of a ...

Viruses that infect bacteria can still do their job in microgravity, but space changes the rules of the fight.

A single thermal performance curve applies across life, from bacteria to animals. Species differ in optimal temperatures, but not in the fundamental shape of their response to heat. Researchers at Tri ...

In the mice with large-brain primate microbes, the researchers found increased expression of genes associated with energy ...
