Humans are technically born ahead of time, and finish development after birth.
If you touch a baby's head you will see that the skull is not fully solid yet. They're also more fragile than other species. e.g: Horses are born and quickly start running.
This is because a baby with a fully developed head could not pass the birth canal.
