Comparative Embryology- This is the study of similar structures appearing during the embryonic development of related organisms.
Related species have similar embryos.
Compare embryonic growth and fetal development in single and multiple pregnancies, including the incidence of complications and infant mortality.
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!!
if you can work out what the 'following animals' are, you'll be a lot closer to the answer!
Fossils, patterns of early development, similar body structures, DNA, and protein structures.
Fossils, Similarities in early development, and similar body structures
Similar structures that evolved independently are called analogous structures, or analogies.
Similar structures that have evolved independently are called homologous structures. An example would be the wings of a bird and the wings of an insect.
