Re: Synapomorphies 2/2 (not 2/1...)



By popular demand...

CI = consistency index: number of characters divided by number of steps in
the tree (therefore between 1 and 0), respectively (for one character) 1 /
the number of state changes.
HI = homoplasy index: (1 - CI)
RI = retention index: Hm... turns out I forgot.
RC = rescaled consistency index: CI / RI

Also, I put Avisauridae in the wrong place. It appears to be defined as
{*Avisaurus* + *Neuquenornis*}, thus probably excluding *Concornis*.
