2. Why do we find so many dinosaur fossils in the Western USA and Canada? 3. What is the key evidence suggesting that dinosaurs are not poikilothermic? 4. What is the relationship between body temperature and metabolism? How does this relationship determine the amount of food that an animal must consume? 5. Reptiles use 1/10 the amount of food that is used by a similar sized mammal. Why is this the case? 6. List three things that non-avian dinosaurs and birds have in common? 7. Creationists have long used bird flight and feathers to denigrate evolution. They use the irreducible complexity argument. Evaluate the following argument: They say in order for flight to occur there had to be complex flight feathers. And these feathers had to be fully formed (half feathers do it), so perfect feathers and won’t flight had to both come into existence together at once—by intelligent design. Biologists cannot provide a satisfactory explanation using gradual evolution, so the creation model is by default correct. 8. Using the reptile phylogeny shown below answer the following: Is the evolution of homeothermy in mammals and birds a homology or homoplasy? What about a 4 chambered heart? An amnion?
