Detailed explanation-1: -Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are likely to be evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails.

Detailed explanation-2: -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-3: -The study of one type of evidence of evolution is called embryology, the study of embryos. An embryo is an unborn (or unhatched) animal or human young in its earliest phases. Embryos of many different kinds of animals: mammals, birds, reptiles, fish, etc. look very similar and it is often difficult to tell them apart.

Detailed explanation-4: -Evidence for evolution: Molecular biology Like structural homologies, similarities between biological molecules can reflect shared evolutionary ancestry. At the most basic level, all living organisms share: The same genetic material (DNA) The same, or highly similar, genetic codes.
