I have to say that, although the paper is loaded with the same
misrepresentations and misconceptions as previous papers by this trio, it is
slightly less incendiary in tone. Although arguing against the hypothesis
that birds evolving from theropods, Feduccia &c do accept that a close
relationship exists between dromaeosaurs and birds. That's one of a very
few well-supported assertions made in the paper.
As before, Feduccia &c support the bewildering notion that birds and dromies
are not theropods, and that birds/dromaeosaurs and theropods evolved from
separate archosaur ancestors with a pentadactyl manus. The usual suspects
rear their ugly heads: a ground-up origin of flight is said to be "largely
falsified", as is the presence of feathers in non-avian theropods;
microraptorans are said to have held their legs outward, and so could not
have been obligate bipeds; primitive theropods could not give rise to birds
because their forelimbs were too short; and so on. Mickey Mortimer would
have a field day.
The paper also features this unintentionally humorous (?Freudian) slip by
Feduccia &c: "The interpretation of microraptors as an early offshoot of the
ancient avian lineage obviates the deficiencies of the theropod origin of
birds." But the word "obviate" does NOT mean "to make obvious"; it actually
means "to render unnecessary". Oops.
