  I guess you mean how babies develop in the womb? This is called fetal development and it’s really amazing because what starts as a single cell when a sperm fertilises an egg grows into a baby with Over the course of 38 weeks it grows into a baby with billions and billions. Scientists are still trying to understand how it all works. It really is a miracle of nature that goes on every day.

  It is absolutely amazing. Actually a lot of the stuff that goes on in development also happens in other mammals. Of course there are some differences.
