Structures as different as human arms, bat wings, and dolphin flippers contain many of the same bones, which develop from similar embryonic tissues. These structural similarities are an example of . Group of answer choices convergent evolution homology the evolution of similar appearance as a result of common function the evolution of common structure as a result of common function
