Shifts in stability and control effectiveness during evolution of Paraves support aerial maneuvering hypotheses for flight origins
The capacity for aerial maneuvering shaped the evolution of flying animals. Here we evaluate consequences of aviaian morphology for aerial performance1,2by quantifying static stability and control effectiveness of physical models3for numerous taxa sampled from within the lineage leading to birds (Paraves4,5). Results of aerodynamic testing are mapped phylogenetically6-10to examine how maneuvering characteristics correlate with tail shortening, fore- and hindwing elaboration, and otherdoi:10.1101/001750 fatcat:nebv46r7fvagxi7jqxnqgu57am
