Evolution to the rescue: Researchers offer hope that species may adapt quickly to rapid environmental change
Evolution is usually thought to be a very slow process, something that happens over many generations, thanks to adaptive mutations. But environmental change due to things like climate change, habitat destruction, pollution, ...
