Re: Terrestriality is a bias

        Sister group, yes, but not ancestors.

        (I said "almost" because some recent evidence suggests that
"Dromaeosauridae" as
        traditionally defined is paraphyletic with regards to birds, in
which case the ancestors
        of birds (and thus birds themselves) would indeed be
dromaeosaurs.  Will have to wait
        and see on that one!)<<

What about GS Paul's theory that dromaeosaurs are flightless early
birds?  Does anyone still hold that theory to be valid (especialy in the
light of the new little dromaeosaurs)?
