Carinatae has been phylogenetically defined as the most recent common
ancestor of *Ichthyornis dispar* (who Clarke is working on resolving the
material for, bless her soul) and Neornithes. Neornithes is the crown
group birds, *Struthio* + *Corvus* as I would formulate it.

Little steps are often the hardest to take. We are too used to making leaps
in the face of adversity, that a simple skip is so hard to do. We should all
learn to walk soft, walk small, see the world around us rather than zoom by it.
