“The milk revolution” and human weaning

First attempt at posting via tablet – please bear with me


“Archaeology: The milk revolution” is one of the most intriguing articles I have read in quite a while.  The collaboration of chemistry, molecular biology and archaeology makes a very compelling story.  

The observation that adult lactose tolerance is a recent evolutionary development would seem to have implications on the understanding of the natural age for human weaning.  Lactase activity in modern lactose intolerant populations begins to decline sometime after age two, and is normally complete by age five.  This could imply that weaning between ages two and five was the natural norm in early humans.
