The Amazon molly reproduces without sex. A genomic copy-and-paste trick called gene conversion may explain how it avoids evolutionary meltdown.

Scientists have uncovered an enormous hidden archive of plant DNA that has endured for more than 400 million years. By comparing hundreds of plant genomes, researchers identified more than 2.3 million ...

Most lethal mutations in wild fruit flies are driven by newly transferred jumping genes, not small DNA errors, according to a new study from Duke University. The findings, published in PLOS Biology, ...

Yale scientists discovered that cavefish species independently evolved blindness and depigmentation as they adapted to dark cave environments, with some lineages dating back over 11 million years.

Research is shaking up how we think about evolution, suggesting there's a level of predictability influenced by genes and genetic history.

Notably, the researchers point out that the strongest signals of selection “are all plausibly related to the consumption of agricultural products.” For instance, in the last 100 generations, there ...
