Which of the following conclusions is supported by the data? (A) Humans and bonobos belong to the same genus because the nucleotide sequence of the TAS2R38 gene is the same. (B) Chimpanzees are equally related to humans and bonobos because all three groups possess variants of the TAS2R38 gene. (C) Humans are more closely related to bonobos than to chimpanzees because the branch of the tree with humans is closest to the branch of the tree with bonobos. (D) Bonobos are more closely related to humans than to gorillas because bonobos and humans share a more recent common ancestor than bonobos and gorillas do.
