Natural selection is the process by which some organisms in a population survive and reproduce, while others do not, based on their bodies and behaviour. It is one of the processes by which species ...

For years, the story of recent human evolution looked relatively quiet. Scientists studying ancient human DNA had found only ...

A massive study of ancient genomes has revealed that natural selection acted on hundreds of human genes throughout recent ...

Data from more than 15,000 ancient people reveal natural selection of hundreds of genes linked to immunity, skin tone, ...

Another complication is that sustained genetic variation does not emerge exclusively as a result of natural selection.

When humans started farming around 10,000 years ago, they reshaped their landscapes, diets, and social structures. A common ...

The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.

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 ...

Researchers believe the trait is an adaptation to counter the females’ post-coital hunger. I’m not sure if lizards can experience PTSD, but if they can, I have every reason to believe this science ...
