Monkeys waiting for fruit to ripen and even ferment so that it is easier to digest is so cool. Making butt scratchers from certain sticks is so silly. The social bonds and friendships of these monkeys is so cute; pec sniffing is unheard of and new. The mechanics behind spider monkey swinging and muscles is so cool. I love how much bonobos were mentioned; I studied them a lot in my anthropology of sex and gender class and how chill they are and how similar they are to humans. Michelle Rodrigues was pretty nice.
