Answer 2

Compare the sequences of common proteins, for example, one of the subunits of hemoglobin.

You'll find that the human amino acid sequence isn't quite the same as the chimp sequence.  You'll find that the mouse sequence is more different.

This supports the idea that humans and chimps had a more recent common ancestor than humans and mice.

You can do similar comparisons with the nucleotide sequences of mitochondrial DNA.
