What is the study of embryology focused on?

The study of embryology is focused on the development of an organism from the fertilization of the egg through various stages of growth until it reaches the early phases of maturity. This field examines the processes that occur during the formation of tissues, organs, and organ systems as the embryo develops. By understanding embryonic development, scientists can gain insights into normal physiological processes as well as potential developmental disorders. The other choices pertain to different biological concepts: the classification of adult organisms relates to taxonomy, the evolution of species pertains to evolutionary biology, and the impact of genetics on behavior falls under the realm of behavioral genetics. Each of these areas is distinct from the study of embryology, which zeroes in specifically on the early developmental stages of organisms.
