I think that the most interesting thing about this guy is how we haven't 
heard back from him...


> With respect to down vs flight feathers of modern birds, Prum's model
implies that insulatory feathers evolved twice:
(1) neormorphic(?) hairlike structures (later branched) in proavian 
theropods;
(2) flight feathers --> insulatory feathers in the line leading to modern 
birds<
Just a though, but if this is the case (down=advanced flight feathers), 
could (3)Fuzz in proavians is derived from flight feathers (a.k.a. these 
animals are secondarily flightless)?
Just talking...
