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

Called “Lamarckian Inheritance,” the theory suggests that those experiences can even be passed down to future generations.

Scientists have uncovered how brewer’s yeast developed its unusually tiny centromeres, the DNA regions that guide chromosome separation during cell division. By studying related yeast species, ...

The stray dogs that roam the Chernobyl Exclusion Zone have become unlikely protagonists in a scientific debate about how life responds to chronic radiation. For years, they have been framed as a ...

Frances Arnold's game-changing technique of "directed evolution" creates enzymes with unusual capabilities. Her own evolution made it possible.

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

All complex biological systems—like the DNA, RNA and proteins constantly being copied and built within our cells—are prone to errors. That means as life evolved to be more elaborate, it also had to ...

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 ...
