In 2004, scientists observing a baboon troop found that the monkeys' culture could change dramatically, and enduringly, for the better. And all it took was massive amounts of death.
No, we're not quite at the point where baboons can tackle calculus or trigonometry, but they do show an ability to count that's at least as good as that of a human child, as this video from the University of Rochester reveals.
Be warned, this video starts off horribly sad, but it's still a fascinating behavior from one of our primate cousins. Baboons in Saudi Arabia kidnap feral puppies away from their packs, bringing them up in the baboon family.
The ability to form analogies, to look at two unrelated situations and recognize the basic similarities that bind them together, was thought to be a uniquely human trait, with some experts speculating that language is a prerequisite for understanding them.
