characters not in the pectoral limb or girdle, I'll be glad to consider them
as well. Then I'll run PHYLIP or PAUP (if I have it in time) on the new
censored data and see how the results are different from the standard data's
results. If your hypothesis is correct, we'll see secondary flightlessness,
if not Aves will only include Archaeopteryx, Rahonavis and pygostylians. >>
Don't see how this will demonstrate anything. In secondary flightlessness, it
is exactly the "flighty characters" that are lost.
