It shows that embryos who develop similarly are not related to one another

It shows that organisms have the ability to evolve, or change, over time

Detailed explanation-1: -Embryology is important to understanding a species’ evolution, since some homologous structures can be seen only in embryo development. For example, all vertebrate embryos, from humans to chickens to fish, have a tail during early development, even if that tail does not appear in the fully developed organism.
Detailed explanation-2: -Answer and Explanation: Comparative embryology shows the similarities in embryonic development between species indicating we all came from one common ancestor that evolved into different species over millions of years.
Detailed explanation-3: -Embryology can indicate evolutionary relationships between groups of organisms only because embryos have undergone less change than adults. Thus, biologists can see those structures that are similar between species at early stages of development.
Detailed explanation-4: -Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. Analogous structures are structures that are similar in unrelated organisms. Comparative embryology is the study of the similarities and differences in the embryos of different species.
Detailed explanation-5: -Similar patterns of embryological development provide further evidence that organisms have descended from a common ancestor.
