I’m glad you made the point about wolves! While watching this vid I kept waiting for Diamond to mention what I consider to be one of the primary examples of domestication- the dog. As the first animal domesticated and done so for a completely different reason, the dog is an important and unique animal which I think should factor into Diamond’s analysis, especially since the presence and domestication of dog-like animals first occured in Eurasia. This could have been an important factor in the division of “geographical luck,” as Diamond puts it, and I think he should have mentioned it.
