<< The authors claim it as evidence for a "Ground Up" model of flight
 evolution for birds, since it had the "prerequisites" of long arms and an

 other members of a non-flying clade (Deinonychosauria), wouldn't it make
 sense to interpret _Sinornithosaurus_, which has more flight
 characteristics than more derived deinonychosaurs, as representative of an
 intermediate stage in the evolution from a flying ancestor to secondarily
 flightless deinonychosaurs? >>
