Walk into consciousness labs, and you will mostly find studies on humans relying on verbal reports. This evidence is then ...

The Christmas Island shrew is thought to be at least the third mammal species to go extinct on the island as a direct result ...

A study in fruit flies suggests an internal genomic arms race may be driving rapid evolution in proteins that still perform an essential, unchanging job: protecting chromosome ends.

Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...
