Bird analysis update 2



I wrote I had 65 characters... wrong, 66.

Now excluded: *Alexornis*, *Lectavis*, *Yungavolucris*, *Boluochia*, *Otogornis*.
Analysis limited to 50 replicates with 1 million rearrangements each. Probably not enough to find all MPTs... 4459 were found.


Strict consensus: Enantiornithes and Euornithes rise from the phylogenetic grass!!! *Liaoningornis* is in Enantiornithes, as are *Protopteryx* and friends. *Jibeinia* is still in the grass. It liked to cluster with *Otogornis* as part of Enantiornithes.

50 % majority-rule consensus (numbers mean clade turns up in _ % of MPTs):

Of the remaining taxa, *Archaeopteryx*, *Hulsanpes*, *Yandangornis*, *Ambiortus* and *Gansus* seem to cause the most instability. That's right, *Archaeopteryx*.

The Adams consensus, which is supposed to identify just those taxa, looks... interesting, for what that's worth. For example, it gives old Archie a fully resolved position:

Now I'll try reweighting with these taxa.
