Their embryos share features in the early stages of development. They both emerge from fertilized eggs. They both emerge from fertilized eggs. Their embryos share features in the late stages of development. Their embryos share features in the late stages of development. They both produce egg and sperm cells that must join in fertilization.

Answer 1

The evidence that supports the theory that fish and mammals evolved from the same ancestor is: Their embryos share features in the early stages of development.

This shared embryonic development suggests a common ancestry, as similar structures and stages during embryogenesis point to evolutionary relationships.
