Which statement represents the best explanation for the observation that the nuclear DNA of wolves and domestic dogs has a very high degree of sequence homology?
A) dogs and wolves have very similar morphologies
B) dogs and wolves belong to the same order

D) dogs and wolves share a very recent common ancestor

Question

Quizplus · Accepted Answer
