Wild scarlet monkeyflowers in California survived a historic drought by relying on a rapid evolution, marking the first time the process has been observed in the wild.

In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

Human evolution is a story writ slow. It’s been about 3.8 billion years since life on Earth emerged and steadily began to spread its reach from the tidal pools to the oceans to ...

The movement of genetic material between organisms that aren’t directly related is a significant driver of evolution, especially among single-celled organisms like bacteria and archaea. A team led by ...

Directed evolution is a laboratory method that speeds up protein mutations to help create novel cancer and neurodegenerative disorder therapies. In a new study, scientists detail a method called ...

Evolution is a complicated thing. Much of modern evolutionary biology seeks to reconcile the seeming randomness of the forces behind the process — how mutations occur, for example — with the ...

Why does natural selection appear to happen slowly on long timescales and quickly on short ones? A multigenerational study of four lizard species addresses biology’s “paradox of stasis.” James Stroud ...

Ironically, one great unsolved problem in Darwin's master work, On the Origin of Species, was just that: How and why do species originate? Darwin and his later followers were faced with a seeming ...
