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 ...

Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

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

If we look across the whole of the mammal branch of the tree of life, we find there are many groups of mammals that have ...

Why did humans evolve the eyes we have today? While scientists can't go back in time to study the environmental pressures that shaped the evolution of the diverse vision systems that exist in nature, ...
