Discover how lactase persistence exemplifies natural selection across human populations and the genetics of milk consumption adaptation. The persistent expression of lactase into adulthood in humans ...

A genetic phenomenon that allows for the selection of multiple genetic mutations that all lead to a similar outcome -- for instance the ability to digest milk -- has been characterised for the first ...

Since the origins of agriculture, humans have maintained a symbiotic relationship with a number of species, such as wheat and corn. We move them around and kill their competitors, and they feed us. In ...
