Natural selection, the evolutionary process that guides which traits become more common in a population, has been acting on us for the past 3,000 years, right up to the modern day, new research ...

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 ...

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.

Natural selection can reverse evolution that occurs through sexual selection and this can lead to better females, new research shows. Natural selection can reverse evolution that occurs through sexual ...

In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...

Some of nature's mysteries have kept scientists busy for decades—for example, the processes that drive evolution. The question of whether certain differences between and within species are caused by ...

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 ...

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 ...
