r embryonic tissues. These structural similarities are an example of ________. 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 ________. the evolution of similar appearance as a result of common function homology the evolution of common structure as a result of common function convergent evolution
These similarities in structural are an example of homology because human arms, bat wings, and dolphin flippers are different organisms that have the common ancestor. The similar bone structure of different organisms and different its function is due to common ancestor. Homology similarity of the structure and physiology of different species of organisms due to their descent from a common evolutionary ancestor so we can say that these structural similarities are an example of homology.
The answer is <span>the number of DNA mutations in an organism is measured over time to determine how long it will take for a new species to evolve.</span>
The barnacles are only able to attach them selfs to surfaces in the water. Since the surface is limited, barnacles are attaching themselves to the other barnacles, crowding the rock. The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.
