The Cultural Consciousness of Toenails

Chimps use sharpened sticks to clean out their ears with, and they also shave off sticks to pick out their toenails. So there's quite a few, quite a lot of evidence of culture in chimpanzees. I wonder if it's to do with the people who put that in an area, that bit of grass, and you're the guys who don't, so it's a tribal. They're going to make them, yeah.
