From swimming to crawling to cruising to walking…

Babies repeat our evolutionary movements: the fetus in utero live in water like fish. Couple months after birth, they become reptilian-like, where their entire trunk and legs are in contact with the ground when they move. Then they become amphibian-like and begin to crawl on legs. Once they can do attached walking, they become primate-like, until finally they stand upright like a fully erect human being. 500 million years of evolution in one year. That’s impressive.
