sentences_after: Partly, this is because they have a great deal to learn. Their life depends less on instinct than other animals, and more on learning. Humans are also born with their brains not so well developed as other mammals. There is a good reason for this. If their brains were better developed they would be larger, and this would make birth more difficult.
