The work demonstrates the power of ancient DNA to illuminate human biology and medicine in addition to history. A massive ...

A new paper in Molecular Biology and Evolution, finds that changes in animal development induced by climate shock persist ...

For decades, scientists have known that bacteria can exchange genetic material, in a process called horizontal gene transfer. This allows bacteria to rapidly evolve new traits, such as antibiotic ...

When Charles Darwin first proposed how evolution works in 1859, it seemed plausible. Tiny changes stack up over time, eventually leading a species to become something entirely different. Aside from ...

Hidden within fish DNA are powerful genetic twists that may explain one of nature’s biggest mysteries: how new species form so quickly. In Lake Malawi, hundreds of cichlid fish species evolved at ...

A giant DNA virus pulled from a Japanese freshwater pond is forcing scientists to rethink how complex cells first acquired their defining feature: the nucleus. Named ushikuvirus, the newly ...

Professor Indraneel Mittra and his team show that DNA fragments from dying cells function as agents of horizontal gene transfer in mammalian cells. For decades, scientists have known that bacteria can ...
