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 ...

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 ...

Researchers find Apennine brown bears evolved into a smaller, less aggressive animal after centuries of coexistence with ...

Are bears getting soft on us? After centuries of living in close proximity with people, a population of brown bears has ...

The evolution of pathogens has received attention in a wide range of scientific fields, such as epidemiology, demography, and evolutionary ecology. Understanding pathogen evolution is particularly ...

Repeated environmental changes can lead evolution in unexpected directions, and research from Vermont shows that studying a single population does not capture the full story of an entire species. All ...

Many people hold the view that evolution in humans has come to a halt. But while modern medicine and technologies have changed the environment in which evolution operates, many scientists are in ...

Discover interesting facts about how evolution works, the different patterns that can emerge from evolution, how quickly organisms can evolve, and whether evolution is a random or ordered process When ...
