It's widely assumed within the evolutionary biology field that weak selection provides an advantage to an organism's ability to evolve. But new research may offer the first experimental proof that ...

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 ...

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.

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 ...

NASA had a big – and little – problem. For a small satellite, the agency needed a tiny antenna, with very specific communication capabilities and very strict limits on size and weight. The agency gave ...

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 ...
