Human and Chimp DNA

APBIO-C3XXPK

When human DNA molecules and chimpanzee DNA molecules are heated to separate the two sides of the molecules from each other and then mixed together at cooler temperatures, strands of human DNA are able to form hydrogen bonds and base-pair with over 98% of the nucleotides in the chimpanzee DNA strands.

Which of the following is the MOST logical conclusion to draw from this information?

A

Humans evolved from chimpanzees.

B

Humans and chimpanzees share a relatively recent common ancestor.

C

Chimpanzees evolved from humans.

D

Convergent evolution has led to similar nucleotide sequences in the two genomes.
