Emerging data suggests the seemingly impossible — that mysterious new genes arise from “junk” DNA.
Scientists hope that new genetic letters, created in the lab, will endow DNA with new powers.
By swapping ancient genes into modern E. coli, scientists hope to tease out the rules of evolution.
Modern birds emerged in a snap of evolutionary time through a series of simple genetic changes.
In the few decades since viruses were first found in the oceans, scientists have only been able to identify a handful of species. A new survey has uncovered nearly all the rest.
Genetically identical animals raised under similar conditions can make very different choices. These distinctions are helping researchers map the biological basis of individuality.
The largest evolutionary tree ever compiled leads researchers to conclude that chance mutation — not natural selection — drives the development of new species.
An infection sweeping through Australia’s struggling koala population provides an unprecedented opportunity to explore how retroviruses insert themselves into the genome.
Inside the cell’s nucleus, the double helix folds up in myriad loops and twists. The quest to unravel this structure is revealing the subtle genetic orchestration of all life on Earth.
