problem 1) In Plingy the Elder's Natural History, he tells the story about beavers. He said that beavers castrated themselves in order to run away hunters who pursued them for their testicles that could be utilized to produce the analgesic medication. This certainly is false.

Could some analogue of natural selection work when culture is a means by which information is transmitted from one generation to another?
