What's more, we have evidence that the lactose processing gene has become widespread in humans in the last 7000 years.
Not to mention the genetic changes that have occurred in the foods over those times.

>The genomic signature of dog domestication reveals adaptation to a starch-rich diet [1]
>Nineteen of these regions contain genes important in brain function, eight of which belong to nervous system development pathways and potentially underlie behavioural changes central to dog domestication6. Ten genes with key roles in starch digestion and fat metabolism also show signals of selection.
