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 ...

The founder effect is an extreme example of "genetic drift." Genes occurring at a certain frequency in the larger population will occur at a different frequency -- more or less often -- in a ...

While evolution involves changes in organisms ... most of the changes in DNA inside individuals are the result of "genetic drift" -- random changes that go on all the time and aren't steered ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the ...
