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

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 ...

Here’s what you’ll learn when you read this story: Directed evolution is a laboratory method that speeds up protein mutations to help create novel cancer and neurodegenerative disorder therapies. In a ...

Evolution is perhaps the most extraordinary story ever told—a tale spanning billions of years that connects every living thing on Earth through an intricate ...

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 ...

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 ...

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 ...

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 ...
