What's the weirdest thing I know about nature?  Oddly enough, the weirdest (well, not necessarily weirdest but definitely the most disturbing) thing I know comes as an unfortunate by-product of being an Anthropology major and taking Primate Behavioral Ecology.  CHIMPS EAT MONKEYS...that's right, they're carnivorous.  Actually, they're omnivorous like us (we are all apes after all).  They specifically like to hunt and east red colobus monkeys.  They'll jump on that like a crack fiend on a loose rock.  Growing up, we go to zoos and watch television, we see chimps in captivity and it's all happy happy joy joy...then you become an Anthropology major and your blissful ignorance gets shot to hell!  You get shown a video footage from a study of chimps in the wild and your world gets turned upside down.  You think those driver's ed car crash videos are disturbing?  Sex ed birth videos made your stomach churn?  Oh no, you haven't seen anything yet.
