Epigenetics in Feast, Famine: How Well Grampa Ate Could Impact Grandkids

Epigenetics (prev) is the study of changes in gene expression or cellular phenotype, caused by mechanisms other than changes in the underlying DNA sequence. David Epstein, a senior writer for Sports Illustrated has written about this topic for his book The Sports Gene (not as reductive as the title might suggest), but cut the chapter because the material he researched was so new as to require that he "caveat the writing rather heavily." Instead, he shared his chapter How an 1836 Famine Altered the Genes of Children Born Decades Later on IO9. You can read or hear more about the book in a half-hour segment from NPR's Fresh Air, opening with a story of Jennie Finch, a softball pitcher who "just whiff[ed] the best hitters in the world."
