A biologist analyzes the DNA sequences in three different primates. The biologist finds that primates A and B have nearly identical DNA sequences. The DNA sequences in primate Care significantly different from those of primate A.
From this information, the biologist may infer that
O primates A and B are more closely related to each other than either is to primate C.
O all three primates appeared on Earth at about the same time.
O either primate A or primate B must be a direct ancestor of primate C.
O primate C must have been the ancestor of both primate A and primate B.
