a. The embryos of the different vertebrate species had homologous structures
b. The embryos of each vertebrate species were identical to the embryos of the other vertebrate species. Therefore, each body part was used for the same function. c. The embryos of simple vertebrate species had no homologous structures or vestigial organs.
d. The embryos of most vertebrate species had no types of structures in common with the other vertebrate species.

Answer 1
