Dear Tweeters,

I'm in over my head here, but does analysis of DNA samples from purported
populations of Northwestern and of American crows show enough similarity to
warrant lumping, or enough difference to warrant splitting? Or does this
just move the same debate to another level? Like, who's to say how much is
enough difference to qualify a population as a separate species?
