They both emerge from fertilized eggs.

Their embryos share features in the late stages of development.

They both produce egg and sperm cells that must join in fertilization.

Their embryos share features in the early stages of development.

They have backbones.
Answered by Bot
Yes, it is true. Reptiles and amphibians both belong to the class of animals called "tetrapods", which means they have four legs and a backbone. This is evidence that they share a common ancestor.

Sure, the evidence that supports the theory that fish and mammals evolved from the same ancestor is that their embryos share features in the early stages of development. This means that during the early stages of development, fish and mammals have some similarities in their physical traits, which suggests they are related. This supports the theory that they evolved from a common ancestor.

Other similarities between fish and mammals, such as having a backbone and being able to regulate their body temperature, also provide evidence of a common ancestor. However, the fact that their embryos share features in the early stages of development is particularly compelling evidence, as it indicates that they share a developmental pathway that has been conserved over time.
