For balance, I would just like to make the point that I also regard the development of epigenetics ideas as valuable advances in our knowledge of biology and evolution, but I don't see how it supports the "intelligent design" scenario. In fact the occurrence of years of low and high crop yields and the resulting nutrition effects all seem pretty random. So it supports evolution by natural selection from chance variation. I didn't notice in the paper any account taken of the people keeping stocks of grain in good years to offset famine years. Surely there was some such activity, unless they were all totally stupid.
