A new study theorizes that evolution ticks at different speeds, especially when a big group of organisms first appears.

An inexplicably hot, fast-growing cluster of galaxies in the early universe has scientists questioning theories of galactic ...

It may have fewer than many of the other sciences, but biology does have two dozen or so “rules”—broad generalizations about the behavior or nature and evolution. Now, USC researchers want to add a ...

Darwinian thinking has been challenged many times, starting with co-discoverer of natural selection Alfred Russel Wallace, who disagreed with some aspects of Charles Darwin’s arguments, but was ...

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 ...

A study published in the Nature journal alters how the evolution of fish has been historically understood. Fossilized fish and other sea creatures have often been pivotal in new scientific discoveries ...

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.
