DNA sequences in many human genes are very similar to the sequences of corresponding genes in chimpanzees. The most likely explanation for this result is that
A) humans and chimpanzees share a relatively recent common ancestor.
B) humans evolved from chimpanzees.
C) chimpanzees evolved from humans.
D) convergent evolution led to the DNA similarities.
E) humans and chimpanzees are not closely related.

Question

Quizplus · Accepted Answer

The similarity in DNA sequences between humans and chimpanzees suggests that they share a common ancestor, indicating that the two species diverged from a common ancestor relatively recently. This concept is supported by other evidence from comparative anatomy, physiology, and behavior of humans and chimpanzees. The other choices (B, C, D, E) are not supported by the available evidence.
