Answer • Paraphyletic
Birds 100points What’s the purpose of a keeled sternum?
Answer • Allows for larger pectoral muscles • Wings capable of flapping motion
Mammals 100 points Describe heterodont dentition
Answer • The specialization of mammals teeth to target specific food
Misc. 100 points Describe the difference between the axial and appendicular skeleton.
Answer • Axial- The cranium, vertebrae, and ribs/sternum • Appendicular- limbs, pectoral and pelvic girdles
Fish 200 points What jawless fish may tie itself in knots and what purpose does this serve?

Reptiles200 points What allowed reptiles to break the tie to water? For an extra 100 pts describe 3 features of this.
Birds 200points • Feathers derived from ___________ and what evidence is there to prove this?
Answer • Scales in retiles • Keratin
Mammals 200 points What was the major evolutionary event that allowed mammals to move more efficiently in contrast to reptiles?
Answer • The shift from legs being at right angles to under the body • Allowed for more rapid and efficient movement • Support for more weight.
Misc. 200 points What is the retention of juvenile characteristics on into adulthood?
Answer • Paedomorphism
Amphibian 300points Name three feature of Lissamphibia ( Modern Amphibians) Daily Double!
Answer • Loss of bone in skull • Loss of scales • Most with 4 digits (not 5) • 2 middle ear bones • Weak teeth • 3 chambered heart
Reptiles 300 points Name 3 reptilian characteristics
Answer • Amniotic egg with yolk (most lay eggs on land) • lack larval stages • Impermeable skin: scales or plates of keratin cover & protect body • Breath via lungs • Ectotherms (except dinosaurs/birds) • Generally 3-chambered heart • (crocodiles & birds have 4)
Birds 300points Explain the difference between endothermyvshomeothermy.
Answer • Endothermy= control body temperatures through internal means such as muscle shivering or fat burning • Homeothermy= thermoregulation that maintains a stable internal body temperature regardless of external influence • Ex) Humans – 98.6 degrees F
Fish 300 points What is an extant organism found today that has remained unchanged through time?
Answer • Living fossil • Like tuatara
Mammals 300points • What is the purpose of skull fenestrae? • For an additional 100 pts, explain what does it mean to be an anapsid, synapsid, diapsid and provide an example of each.
