    Not significant at all.  We already knew that vertebrate tetrapods had lobefin fish ancestors.  So someone found tiktaalik, a lobefin fish with a few tetrapod-like features.  Yay, goody.

    I LOVE TIKTAALIK! What a cutie. Other transitional animals I like are Procynosuchus, Miacis, Caudipteryx and Pakicetus. My favorite is Miacis, because he's the last common ancestor of bears, cats, dogs and foxes.

    SO CUTE!
