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

Question

Quizplus · Accepted Answer

Humans and chimpanzees share a relatively recent common ancestor, which explains the high degree of similarity in their DNA sequences. This is a fundamental concept in evolutionary biology, indicating that both species diverged from a common lineage rather than one evolving from the other or the similarities arising independently through convergent evolution.
