Phylogenetic analysis of the evolution of lactose digestion in adults

There is positive selection for high lactose digestion capacity among adults in populations living in drier environments (615).

Aridity was estimated by the number of months per year with less than 50 ml of rainfall in the area inhabited by each population.
