All four groups have wings because of a common winged ancestor C.All four developed flight independently from non-winged ancestors D. Insects and birds evolved flight independently but pterodactyls are the winged ancestor of bats E None of the choices are correctExplanation / Answer
1) The correct option is C. they do not include all descendants of their ancestors.
Nonavian reptiles refer to a paraphyletic group, which includes the living turtles, lizards, snakes, tuataras, and crocodilians and a number of extinct groups.
2) The correct option is B. synapsids lineage.
Mammals belong to a group known as synapsids.
3) The correct option is E. all of the choices are nonavian reptilian characteristics.
All the given options are characteristics of nonavian reptiles.
4) The correct option is E. Kinetic.
The evolution of joints between the skull and jaw, as well as new joints allowing the jaws to separate and manipulate food has resulted in a kinetic jaw. Most vertebrates have kinetic skull. It is used in the movement between the upper jaw and the brain case.
