What conclusion can you draw from the fact that many modern whale species have vestigial pelvic and leg bones? Options: The ancestors of whales may have been land mammals, Whales could walk if they wanted to, Whales are preparing to evolve into land animals, Someday whales will be able to walk and will have legs.

Scientists discover that cells from two species of organisms are made up of similar proteins, suggesting a close evolutionary relationship. If the scientists do further biochemical analyses, which additional finding would support this conclusion? Options: The fossils of both organisms are found relatively close to each other in the fossil record, The anatomical structure of both organisms is similar, The DNA nucleotide sequence of both organisms is similar, Both populations of organisms have undergone natural selection over time.

Back

The anatomical structure of both organisms is similar.
