Detailed explanation-1: -Embryology is important to understanding a species’ evolution, since some homologous structures can be seen only in embryo development. For example, all vertebrate embryos, from humans to chickens to fish, have a tail during early development, even if that tail does not appear in the fully developed organism.
Detailed explanation-2: -Embryology can indicate evolutionary relationships between groups of organisms only because embryos have undergone less change than adults. Thus, biologists can see those structures that are similar between species at early stages of development.
Detailed explanation-3: -Embryos of different species have differences and similarities in structures up to a certain period during gestation. Human, pig, reptile, and bird embryos have similar embryonic development but as they grow, they transform into their respective species. This demonstrates common ancestry.
Detailed explanation-4: -It involves studying the formation, growth, and development of a new individual from an egg. It deals with the prenatal stage of development, including fertilization, formation of the zygote, and development of embryos and fetuses. Hence, embryology leads us to the understanding of evolution.
