Speaking of amylase, I was reading an article on recent human
evolution in the New York Times today, and ran across:

  Amylase is an enzyme in the saliva that breaks down starch. People who
  live in agrarian societies eat more starch and have extra copies of
  the amylase gene compared with people who live in societies that
  depend on hunting or fishing.

Interesting, no? It's referring to evolution between 10,000 years ago
(the start of agriculture) and now.
