The correct answer is Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor.
Explanation:
Both humans and chimpanzees are primates; this means both species belong to the same biological order (rank in taxonomy). Moreover, humans and chimpanzees share most of their DNA (around 99%). This indicates the two species are related and they evolved from the same ancestor. This implies a primate that existed million years ago (common ancestor) was the origin of these two species and due to this common ancestor they share most of their DNA; however, as both species changed separately the remaining DNA is different and this makes both species look and be different. According to this, the correct statement about the evolution of primates is "Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor."
