Why might biochemical evidence suggest that the rabbit is less evolved than the horse and the pig?

LOL.


Let's define ';less evolved'; as ';having more in common with the common ancestor.';





There's a problem here. We don't have the common ancestor of rabbits, pigs, and horses around to compare with. But if we did, we could compare amino acid sequences of certain key metabolic proteins, and the one that's most like the sequence of the common ancestor's would be the one that's ';less evolved.';Why might biochemical evidence suggest that the rabbit is less evolved than the horse and the pig?

There is no such thing as ';less evolved';; all organisms are just as highly evolved as each other.
