The tree shows one lineage of ornithischian dinosaurs and many lineages of theropod dinosaurs. Some important traits are mapped on the tree including the aspects of feathers, digits of the hands and a few behaviors. a. What phylogenetic function do the Ornithischian dinosaurs play in this tree? b. What trait is shared by all theropod dinosaurs? c. Only two lineages are thought to be capable of flight. What trait may have helped their wings to be strong enough? d. What seems to happen to the bones of the hand across this tree of dinosaurs? e. What other bone characteristics might be important to ultimately enabling flight?
