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

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 ...

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

A bright red splash on a butterfly’s wing is more than a pretty pattern. It is a warning label, honed by millions of years of ...

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 ...

Scientists have uncovered a surprising new picture of human origins that challenges the long-held idea of a single ancestral ...

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 ...

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 ...
