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

A new study from Northwestern University is reshaping how scientists think about brain evolution. The research suggests that ...

It may have fewer than many of the other sciences, but biology does have two dozen or so “rules”—broad generalizations about ...

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 ...

The missing link in the mystery turned out to be an event called the Cambrian explosion. It was only after it that living ...

The process of evolution usually takes thousands, millions or even billions of years. But researchers have found a way to condense it into a matter of minutes using a method called 'directed evolution ...

A genomic atlas of Nematostella vectensis reveals how primitive animals created multiple cell types millions of years ago, ...

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.

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 ...

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 ...

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