Some organisms have anatomical structures that are very similar in embryological development and form, but very different in function. These are called homologous structures. Since these structures are so similar, they indicate an evolutionary relationship and a common ancestor of the species that possess them.

In all three species egg mortality and time needed for embryonic development to hatching increased when pH declined, but no significant effects were found on

Embryological structures

Throughout this course the students should understand complete details about the structures, development of human embryo at different stages including gametogenesis, fertilization, and implantation. Also, the students have the ability to correlate between the embryological structure and its clinical significance. One such structure that is used in classification of animals is the coelom. A coelom is a body cavity that forms during early embryonic development.
