Evolution of lactose tolerance: Why do humans keep drinking milk? - Slate Magazine
"In an evolutionary eye-blink, 80 percent of Europeans became milk-drinkers; in some populations, the proportion is close to 100 percent. (Though globally, lactose intolerance is the norm; around two-thirds of humans cannot drink milk in adulthood.) The speed of this transformation is one of the weirder mysteries in the story of human evolution, more so because it's not clear why anybody needed the mutation to begin with. Through their cleverness, our lactose-intolerant forebears had already found a way to consume dairy without getting sick, irrespective of genetics." - Ken Morley from Bookmarklet
"Everywhere that agriculture and civilization went, lactose tolerance came along. Agriculture-plus-dairying became the backbone of Western civilization." ... but agriculture without dairy is the backbone of East Asian civilization... (except Tibet, I guess.) - Andrew C (✔)
Neat article, although I would have settled for "Because it tastes so good". :-) - Brian Johns
