Snails on a tiny rocky islet evolved before scientists' eyes. The marine snails were reintroduced after a toxic algal bloom wiped them out from the skerry. While the researchers intentionally brought ...

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 ...

The rapid evolution of cicadas' flight ability may have been spurred by the emergence of predatory birds, new research suggests. These insects' bodies and wing shapes changed dramatically over the ...
