Which of the following statements is true about the phylogenetic tree shown here?
A) A combination of molecular data, fossil records, and anatomical homologies show the human is more closely related to the chimpanzee than to the green monkey.
B) The green monkey and rhesus monkey cannot reproduce with each other because of a postzygotic isolating mechanism.
C) The chimpanzee and human must have evolved as a result of allopatric speciation.
D) There is no single common ancestor to all of the organisms displayed on this phylogenetic tree.
E) The gibbon and human are no more closely related than the green monkey and human are.

Question

The phylogenetic tree shows the evolutionary relationships between different organisms based on molecular data, fossil records, and anatomical homologies. The branches on the tree represent the divergence of different species from a common ancestor. In this tree, the human is more closely related to the chimpanzee than to the green monkey, which is supported by a combination of molecular data, fossil records, and anatomical homologies. Therefore, option A is the correct choice. Option B is incorrect because there is no information given in the tree about postzygotic isolating mechanisms between the green monkey and rhesus monkey. Option C is incorrect because there is no information given in the tree about allopatric speciation between the chimpanzee and human. Option D is incorrect because there is a single common ancestor to all of the organisms displayed on this phylogenetic tree. Option E is incorrect because the gibbon and human are more closely related than the green monkey and human are.
