Human embryos have tails, which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and
mammals. Humans also have hair and produce milk to nourish the young, which is unique
to mammals. What does this
indicate?
(1 point)
O a close evolutionary connection between humans and many other mammals
O a close evolutionary connection between humans and many other reptiles
O a very distant evolutionary connection between humans and many other mammals
a very distant evolutionary connection between humans and many other reptiles



Answer :

The presence of tails in human embryos, which later develop into tail bones, indicates a close evolutionary connection between humans and many other mammals. This is because the development of tails in embryos is a shared trait among mammals. The fact that humans also have hair and produce milk to nourish their young further supports this connection. When looking at the characteristics mentioned in the question: - Tails appearing in human embryos and other mammals - Humans having hair and producing milk like other mammals These shared traits point towards a common evolutionary history between humans and other mammals. This suggests that humans and many other mammals share a close evolutionary relationship, as indicated by the similarities in embryonic development and reproductive traits.
