If two different animal species are found to go through equivalent stages of embryonic development until the very last stage, which conclusion would this phenomenon support?

The two animal species are very closely related

The given phenomenon support that the two species are closely related, it means that their genomic information is very similar. So, the information that regulates the embryonic development is also almost similar.

But it does not mean that they are identical to each other. The stages of embryonic development are the same only in the same species. It differs based on their ancestral relationship.

the scientific method.
