The similarities suggest that vertebrates passthrough each of the adult stages of their evoluntionary history as they develop. C. The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species D. The similarities suggest that chickens and humans descend from ancestors with genes that code for the development of tails and gill slitsarrow_forward
