Evolution seems to follow a script more often than expected. Researchers found that distantly related butterflies and moths ...

Galapagos daisies evolved similar jagged leaves through different genes. This shows evolution can reach the same result in ...

Co-evolution between host and pathogen is, in principle, a powerful determinant of the biology and genetics of infection and disease. Yet co-evolution has proven difficult to demonstrate rigorously in ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

What happens when natural selection, the most powerful process driving change in the living world, shapes artificial ...

Extinct species Strange mammal ancestor laid huge, leathery eggs —‬ and it was key to surviving the world's worst mass extinction Dinosaurs 95 million-year-old Spinosaurus had a scimitar-shaped head ...

Earth's biodiversity is in crisis. An imminent "sixth mass extinction" threatens beloved and important wildlife. It also threatens to reduce the amount of genetic diversity—or variation—within species ...

Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...
