Q: What are the golden ages of first jawed vertebrates and the first amniotes?
A: a) Golden age of first jawed vertebrates (= fishes) was Devonian period of Palaeozoic era.
b) Golden age of first amniotes (= reptiles) was Jurassic period of Mesozoic era.
Q: What are pneumatic bones? How do they help birds?
A: a) The bones with air cavities are known as pneumatic bones.
b) Pneumatic bones make the endoskeleton of birds light (one of the flight adaptations).
Q: How does mature RBC of a Mammal differ from that of other Vertebrates?
A: a) Mature RBC of mammals are circular and biconcave. Where as in other Vertebrates they are oval and convex.
