Were this valid I would expect marsupials to be smarter than humans based on ratio of birth size to adult size. Or is a pouch considered an exo-womb?

- nicole_express 10y agoMy understanding is marsupials have the problem that when they're born they need to have a solid enough skull to grasp onto the teats in the pouch, which ends up limiting the potential final brain size the skull can grow to.
