Scientists discover that cells from two species of organisms are made up of similar proteins, suggesting a close evolutionary relationship. 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.
