A new breakdown of earthworm DNA could help us better understand how evolution works, and it could prove Darwin completely wrong.

Humans have been getting infected by ancient bacteria and viruses for at least 37,000 years. Now, for the first time, ...

When people think of DNA, they usually think of genes, the parts that code for proteins and drive inherited traits. But there ...

PROTEUS, a system designed to harness “directed evolution,” can speed the process up by years, or even decades.

Evolution is a gradual change to the DNA of a species over many generations. It can occur by natural selection , when certain traits created by genetic mutations help an organism survive or reproduce.

Chunks of flipped DNA appear to accelerate evolution in fish. This discovery could reshape our understanding of how biodiversity arises. Scientists have discovered that segments of “flipped” DNA help ...

Worms radically reorganized their genomes during their move from sea to land, supporting the theory of punctuated equilibrium in evolution.

By analyzing ancient DNA, scientists determined when, where and how our ancestors got sick from infectious diseases.

In some ciliates, the DNA sequences of the germline genomes have been profoundly modified during evolution, providing unprecedented examples of germline DNA malleability. Although the significance ...

A lost chapter in human evolution has been revealed after an analysis of modern DNA found that we come from not one but two ancestral populations—ones that drifted apart and later reconnected ...

Researchers at the Francis Crick Institute and UCL have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread ...
