Over the past 10,000 years, natural selection has contributed to the evolution of nearly 500 genes in the DNA of West Eurasians, affecting their looks and susceptibility to different illnesses, a new ...

Density-dependent natural selection arises when the fitness of individuals varies according to the number of conspecifics sharing limited resources. In Drosophila, larval crowding has been a classic ...

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.

Population genetics investigates how genetic variation is distributed and changes within and between populations under the combined influence of evolutionary forces. Central to this field are genetic ...

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 ...
