By identifying the bones as being homologous and by proposing that humans, bats, and dolphins share a common ancestor.

Homologous structures
Embryonic structures are those parts of the embryo of animals. They differ from the structures that are found in term infants.

Embryonic shoots are the structures in seeds that become the stem of the new plant. This shoot grows up through the soil surface.

Related species have similar embryos.

It is either homologous structures or homozygous structures. Embryological structures are when different species of animals look similar in the earliest stage of development and Analogous structures are when animals look different but their function is basically the same. So just look up homologous structures and homozygous structures in your Bio book!!

Comparative Embryology- This is the study of similar structures appearing during the embryonic development of related organisms.
Sometimes there are similarities in the embryonic stages of organisms that don't exist in the adult stages.
The chicken, the fish, and the human. :)
Preembryonic forms are the zygote (fertilized egg), morula (a solid ball of cells), blastocyst (hollow ball with a single germ layer), and bilaminar embryonic disc(with two germ layers).
