Yeah, I was bemused by how he basically ignored how all but a handful of our ancestors were wisely living well south of the "harsh winds and eternal snows." We hear a lot about the ice-enduring mammoth hunters because they lived in Europe, and European anthropologists can be kind of self-centered. But for every ice age mammoth hunter, there were probably 10 or 20 ice age people living in nice balmy places like Africa, India, South Asia, and so on.
