Imagine that a researcher is comparing the sequence of several protein-coding genes among mice, rabbits, and humans. she finds that, for most of these genes, the rabbit sequences are more similar to the human sequences than are the mouse sequences. what can she deduce? mice and rabbits do not share a common ancestor. mice and humans share a more "recent" common ancestor than do rabbits and humans. no similar proteins exist in mice and humans. more sequences are conserved between rabbits and humans than between humans and mice. humans and mice do not share a common ancestor.
