But if he goes without milk for months or years, he loses that ability...
That theory is disputed by many investigators, most recently U.C.L.A. Anthropologist Robert McCracken. He believes that the ability to secrete lactase and digest lactose is determined in the genes. Virtually all normal mammals have a gene that turns on the supply before birth, maintains it at a high level until weaning, and then allows it to decline. When man first emerged as Homo sapiens, says McCracken, and for tens of thousands of years thereafter, he was a hunter and gatherer of food. He had no milk cattle. A baby was usually weaned by the age of two. Nature designed milk...
