Mutation is the source of genetic diversity on which natural selection acts, therefore understanding the rates of mutations is crucial for understanding evolutionary trajectories. In this Opinion ...

Random genetic drift has certainly played a big role in human evolution. Human populations were tiny until around 10,000 years ago, and went through a major bottleneck around 2 million years ago.

T. Hofer, N. Ray, D. Wegmann, L. Excoffier (2009). Large allele frequency differences between human continental groups are more likely to have occurred by drift during range expansions than by ...

Molecular Evolution: Neutral Drift: While evolution involves changes in organisms that we can observe, they undergo evolution at a deeper level, too.

Genetic Drift and the Founder Effect: Eastern Pennsylvania is home to beautiful farmlands and countryside, but it's also a gold mine of information for geneticists, who have studied the region's ...

"Regressive evolution," or the reduction of traits over time, is the result of either natural selection or genetic drift, according to a study on cavefish by researchers at New York University's ...

The power of the genetic drift was consistently higher than that estimated from the observed count of SARS-CoV-2-positive persons in England by one to three orders of magnitude, throughout time ...
