Here's one on birds.
Quote:This new tree contains several notable surprises. For example, falcons are more closely related to songbirds than to other hawks and eagles. The closest kin of the diving birds called grebes turn out to be flamingos. And tiny, flashy hummingbirds, according to the new tree, are just a specialised form of nighthawks, whose squat, bulky bodies make them an unlikely cousin.
In fact, the new tree ended up regrouping about a third of all the orders in earlier phylogenies of birds. "That shows you how inconsistent it has been," says Reddy.
