Hidden within fish DNA are powerful genetic twists that may explain one of nature’s biggest mysteries: how new species form so quickly. In Lake Malawi, hundreds of cichlid fish species evolved at ...

It usually takes millions of years for new species to evolve, but not for fish in one African lake.

As early humans spread from lush African forests into grasslands, their need for ready sources of energy led them to develop a taste for grassy plants, especially grains and the starchy plant tissue ...

One hundred years ago, a small town in eastern Tennessee captured the attention of the entire country. A biology teacher in Dayton was accused of teaching human evolution to his students — which was ...

A fish thought to be evolution’s time capsule just surprised scientists. A detailed dissection of the coelacanth — a 400-million-year-old species often called a “living fossil” — revealed that key ...

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 ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. The story of how us humans—and other mammals—got our noses may have just gotten more complicated. This is the conclusion ...

A study has traced thousands of conserved regulatory elements back 300 million years, revealing deep principles of plant genome evolution—a discovery that could pave the way for more precise ...
