Why humans are born without teeth, while other animals are born with fully developed teeth?

Ever try nursing a human child with teeth? Think about it.

Why humans are born without teeth, while other animals are born with fully developed teeth?
I've heard that babies are born with teeth but they look really stupid so before the mum sees it, the midwifes make them drink loads of cola to dissolve them instantly. Works every time apparently...
Reply:because animals and humans are not the same...
Reply:Actually, mammals are born without teeth because it is a selective advantage since we nurse our young. I'm sure if babies did have teeth, there would be no way the mother would be willing to nurse it if it was going to bite its nipples! Here's a good website that talks about mammals and teeth.
