The diagram shows the embryo development of four vertebrates and suggests all of the following EXCEPT
A) common ancestry of vertebrates.
B) there are significant differences in the embryos of all four groups.
there are very few differences in the development of any vertebrates.
D) common features (gills and segments) in the embryos of all vertebrates.
Even though I can't see the diagram, there are rarely too many differences in embryos development, they all come from a common ancestor, and most vertebrates had gills when they were developing. Even human fetus'.
