Archaeology: The Milk Revolution
5th August 2013
Young children almost universally produce lactase and can digest the lactose in their mother’s milk. But as they mature, most switch off the lactase gene. Only 35% of the human population can digest lactose beyond the age of about seven or eight (ref. 2). “If you’re lactose intolerant and you drink half a pint of milk, you’re going to be really ill. Explosive diarrhoea — dysentery essentially,” says Oliver Craig, an archaeologist at the University of York, UK. “I’m not saying it’s lethal, but it’s quite unpleasant.”
Hmmm. I hear ‘enhanced interrogation technique’….
