Breda at The Breda Fallacy discovered an article about female chimpanzees making spears to hunt bushbabies. This article does several things.
It gives the lie to outraged claims that humans are the only species to use weapons.
It is yet another bit of evidence to use while laughing at idiots who believe that it's somehow "unnatural" for humans to eat meat (since our closest genetic link hunts).
It yet another, perhaps unnecessary, proof that those who think violence (they would, of course, equate hunting with violence) is an exclusively male domain are fruitbats.
