The tree shows one lineage of ornithischian dinosaurs and many lineages of theropoddinosaurs. Some important traits are mapped on the tree including the aspects of feathers, digits of thehands 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 bestrong 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?
Which of the following statements is BEST supported by the phylogenetic tree?
A
The development of a bony skeleton was a significant evolutionary step for ocean-dwelling animals.
B
Most warm-blooded animals evolved to have hair, while cold-blooded animals did not.
C
Most land animals require a vertebral column, while ocean animals do not.
D
The evolution of the amniotic egg was specific to ocean-dwelling animals.
Which is NOT an example of a structural homology? Please choose all applicable options. a) All vertebrate embryos form pharyngeal pouches.b) Vertebrate forelimbs generally have the same number and a similar arrangement of bones.c) The same group of embryonic cells forms the adult jaw of a perch and of a dog.d) All organisms share a common genetic code.
