This morning I slept in way too late by accident. So I really shouldn't still be up.

I just read a really good article:
Cowgill, G L (1975) “On causes and consequences of ancient and modern population changes.” American Anthropologist 77: 505-525.
Well, it was good for me. It's not exactly something that's going to astound the lay reader. But I was very pleased to see such an eloquent demolition of the use of "population pressure" as an explanation for social change. And he made the excellent point, which I've been trying to make for a long time, that social change isn't based on what's best for society, it's based on what's best for the people in power. Or what they think is best, at any rate. So yes, I'm an anthropology dork.
