Detailed explanation-1: -Similar patterns of embryological development provide further evidence that organisms have descended from a common ancestor.

Detailed explanation-2: -Similar anatomy across different species highlights their common origin and can be seen in homologous and vestigial structures. Embryology provides evidence for evolution since the embryonic forms of divergent groups are extremely similar.

Detailed explanation-3: -Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos.

Detailed explanation-4: -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.
