14. Which of the following statement is the most likely explanation to support these
observations? "The upper forelimbs of humans and bats have fairly similar skeletal
structures, whereas the corresponding bones in whales have very different shapes and
proportions. However, genetic data suggest that all three kinds of organisms diverged
from a common ancestor at about the same time."
(A) Forelimb evolution was adaptive in people and bats, but not in whales
(B) Whales are not properly classified as mammals
(C) Genes mutate faster in whales than in humans or bats
(D) Natural selection in an aquatic environment resulted in significant changes to
whale forelimb anatomy
