If the development of an organism is controlled by its genes…what could you hypothesize about the DNA of these embryos?

amber has allowed scientists to study dna that has been preserved over millions of years.

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
