Re: Why are humans so bad at childbirth?
In comparison to animals, humans give birth to a clean slate. Your kid could become a doctor, or an athlete, or a politician or a ditch digger - but a puppy will remain a dog who would have limited needs and predictable learning capabilities. Most of the capabilities of animals are genetically built in so the package is pre-programed. Plus a polar bear cub will be born in a predictable environment, same with a mountain goat baby or a rattle snake. But humans can be born anywhere so the body should be flexible enough to survive and adapt under any condition. That makes the baby more fragile. Try to shoot a fragile baby out of 3 inch wide hole and it becomes obvious how careful you need to be.
hence not as fragile as human babies.
