<u>Embryology </u> is the study of the early development of an organism, and it is quite often used to show similarities and differences between different organisms in their early stages of development.
Explanation:
Embryology can be described as the branch of biology which is concerned with the development of sex cells, fertilization that occurs and development of the embryos. In other words, the formation of an embryo, their growth and development are studied in embryology.
Embryology studies can be used to compare the different stages of embryological development in different organisms. Embryology studies might also show evolutionary histories among organisms by inspecting which organisms have similar stages of embryo development.
