Embryology is the study and analysis of embryos. Evidence of an evolutionary common ancestor is seen in the similarity of embryos in markedly different species. ... Embryos and the development of embryos of various species within a class are similar even if their adult forms look nothing alike. What physical similarities exist between each of the embryos? Each of the embryos has the same basic shape, including a tail. They all have external segmentation where the backbone will eventually develop. ... these embryos can be used as evidence of a common ancestor between each of these six organisms.
