When a woman goes into labour, is it her body that decides the baby is ready, or does the foetus send some sort of signal to the mother’s body to say it’s ready to come out?

Question

As above. Also, how would the answer to this title question explain babies that are born premature, or babies that are born so late that the labour has to be induced?

Thank you in advance! I have wondered this for a while!

I mean, I know that babies are not supposed to be born as early as they are. We should stay in for another 6 months to a year for development. We only come out because the baby’s head would be too damn big to fit through the vaginal canal and we would kill our mother trying to come out any later. If you look at most other mammals, they can move/crawl/stand/run right after they’re born. Humans are stupid
