At what point on the evolutionary ladder did humans develop ambilical cords in the woumb?
Are there other species which have ambilical cords?
What is the explanation for lack of ambilical cords in other species and why we need it during the fetus development.
This is an area of science I never had the time to study. Are there any books on this very subject?
