A massive study of ancient DNA from nearly 16,000 people across more than 10,000 years in West Eurasia reveals that natural selection has shaped modern human genomes far more than previously thought.

Additive genetic variance might usually be expected to decrease in a finite population because of genetic drift. However, both theoretical and empirical studies have shown that the additive genetic ...

HUMANS HAVE never been immune from the pressures of natural selection. Throughout the history of the species circumstances have arisen to give individuals with certain beneficial mutations an ...
