The Evolutionary View Of Human Tails
A human embryo at 7 weeks. You can clearly see a tail.
Interestingly, although most invertebrates do not have tails (such as crabs and the majority of insects), every species of mammal has a tail at some point in its development. Even human embryos will have a tail-like structure during their fifth to eighth week of development. The tail is only present for a period of 4 weeks, with it being most prominent in embryos 31-35 days old.
