Re: Livezey and Zusi's paper plagued with convergence?
Now that I have the data matrix, we can see where these large flightless
birds end up according to their data. All three form a clade sister to
Aptornis (another large extinct ground bird) in Gruiformes. Seems
somewhat suspicious to me. Dromornithids are supposed to be related to
anseriforms, Sylviornis to galliforms, and Gastornis to anseriforms or
maybe gruiforms. Are even huge, detailed morphological analyses just
doomed to convergence?
Or maybe they just contain a few hundred correlated characters. Figuring
that out would make a nice Ph.D. thesis or three.
