Studies of the denaturation temperatures of hybrids of human and different apes' DNA provided us with what new information, after morphological studies fell short of resolving the primate phylogenetic tree?

Question

Quizplus · Accepted Answer

Studies of denaturation temperatures showed that chimpanzees are more closely related to humans than gorillas, which provided new information regarding the primate phylogenetic tree. This was not evident in morphological studies alone. Option A is incorrect because bonobos and chimpanzees are already recognized as two different species. Option B is incorrect because the denaturation studies showed that chimpanzees are more closely related to humans than gorillas, and not the other way around. Option D is also incorrect because it is an established fact that Old World monkeys are separate from the apes.
