When most people think about natural selection, they imagine individuals competing with one another: The fastest animal ...

Most of us know that as living things evolve, they take on traits that help them thrive in their home environments. But how are certain traits "chosen" for future generations, and how are others cast ...

New research challenges the one-level view of evolution, showing natural selection works on individuals and groups together.

Survival of the fittest. Nature red in tooth and claw. The common view of natural selection is based solely on the individual: A trait allows an organism to out-compete its rivals and is thus passed ...

A team of global experts has discovered new signals of natural selection in humans. Led by UC Santa Barbara Tsimane Health and Life History Project co-director Michael Gurven, the team studied two ...

Diffuse coevolution is also known as multi-species or guild coevolution. It occurs when several species collectively influence one another. An example is pollination systems in which plants interact ...

New research suggests that natural selection, famous for rewarding advantageous differences in organisms, can also preserve similarities. The researchers worked with a plant called wild radish and its ...

For well over a century, Darwin’s theory of natural selection has served as biology’s grand unifying framework, explaining how species adapt and evolve through the differential replication of randomly ...

Diseases have the potential to shape human evolution, leaving an indelible mark on the genetic code of generations to come. And that’s exactly what happened in South America, finds a study published ...
