Which is why Aborigines with their massive cerebral cortexes and tiny cerebellyms have crazy ritualistic cultures where almost every single thing you do is determined by tradition, with rules dictating everything from how to welcome a person to how to cut up a kangaroo, with stupid specific vocabulary, like a word specifically for that dead kangaroo, another word for kangarro as a target to be hunted, kangaroo as an animal in general, and another word for kangaroo you use when talking about kangaroos in front of women. (things that are often poorly recorded, because the linguists never thought of that)
