I actually really liked the article immediately after that, the one by Adam Gopnik about how dogs became dogs (it's thought that wolves started hanging around human settlements to scavenge food; the more friendly ones got fed and rewarded and eventually taken in and, through inadvertent selective breeding of the friendlier ones, become more and more pet-like). I read a National Geographic article a few weeks ago that indicates scientists are now deliberately doing the same thing with foxes. You can't usually take a wild animal in and train it to behave like a pet, but in some cases apparently you can breed it to become a pet after several generations. So they've created foxes that act like friendly dogs.
An interesting but unmentioned sidenote to that piece: At one point, Gopnik mentions that some people tend to describe dog thinking in really mechanical terms (e.g., they act loving to their owners because they get rewarded with food, etc.), and notes that at one time we thought babies didn't have much in the way of nuanced thoughts and feelings, either. But now scientists have discovered that babies actually do complex inner lives (though, like dogs, they aren't based on language). What he doesn't say is that his sister, Alison Gopnik, is a nationally renowned researcher in this very field. She co-wrote "The Scientist in the Crib." I interviewed her a couple of times.
