Stephen J. Gould said that “there’s been no biological change in humans for 40,000 or 50,000 years.” Gregory Cochran and Henry Harpending beg to differ and, in “The 10,000 Year Explosion,” point to evidence for a recent acceleration in human evolution (e.g. lactose intolerance) ((Fans of the Coen brothers will recognize the title of this post as a kind of a quote from one of their films, and will indulge me. Others, not, on both counts. So be it.)) and blame it on agriculture. Not everyone agrees. I can’t help finding the idea of the end of genetic change somewhat preposterous, a priori. ((Culture doesn’t replace genetic change, “culture constrains genetic changes.”)) But one must find data. Check out the interview with Cochran at 2blowhards. ((It’s in several parts, and some of the internet buzz on the book is rounded up in this installment.)) What all this means to us here, of course, is that when we assess variation in the nutritional value of agrobiodiversity, we need to remember that that value may differ among human individuals and populations.

Indigenous pasta sauces
I don’t think we nibbled it here, but I did post on Facebook a news story about how Italy is thinking of banning ethnic restaurants. This elicited more comments than I usually get. One friend said he’d send me a kebab in the mail. I politely declined, citing health concerns. Another suggested such a ban would be a good idea, as most ethnic restaurants in Italy are terrible, even when — or is it because — they absorb local ingredients and ways of doing things. ((As dissected so admirably for Chinese restaurants by the writer Jennifer 8. Lee (æŽç«¶) in a recent, wonderful, TED talk.)) My wife wondered whether the move might set off tit-for-tat bans on Italian restaurants — including pizzerias ((Talking about absorbing local ingredients, is there a more spongiferous food than the pizza?)) — around the world. And another commenter wondered what Italian cuisine would be like if pasta sauces featured only indigenous agrobiodiversity. That means no tomatoes. One sauce that I could think of that is composed solely of ingredients that could be said to be native to Italy — whatever that might mean — is pesto. Anyway, one thing is for certain, such a cuisine would probably drive me to kebabs.
