Penn Team Links Africans’ Ability to Digest Milk to Spread of Cattle Raising

blurb: 
A new study led by University of Pennsylvania researchers — constituting the largest examination ever of lactase persistence in geographically diverse populations of Africans — investigated the genetic origins of this lactose tolerance and offers support to the idea that the ability to digest milk was a powerful selective force in a variety of African populations which raised cattle and consumed the animals’ fresh milk.

Babies are born with the ability to digest lactose, the sugar found in milk, but most humans lose this ability after infancy because of declining levels of the lactose-digesting enzyme lactase.
