Which statement is correct? All vertebrate and embryos have ears? Or all vertebrae embryos have tails? Or all vertebrae embryos have legs? Or all vertebrae embryos have hair?

Answer 1

The statement "all vertebrate embryos have tails" is correct. During early development, all vertebrate embryos have a tail-like structure, which may be more pronounced in some species than others. Eventually, this structure either regresses or develops into the tail of the fully formed animal.
