As far as the origins of dogs - has anyone else read Dog Sense yet? I'm not finished it, but the first couple of chapters are about how exactly dogs became what they are. Obviously what we know changes frequently, and the author says such, but I was fascinated reading it - it all made more sense than much of what I've read before in my mind. I'm reading it on my Nook, so I haven't really looked at the references yet, but it is clearly cited and the author is a scientist, so hopefully they are decent references. I'd be very interested in others' take on it.
