Fish 100 points What period did fish dominant? Answer • Devonian (Age of Fishes) Amphibians 100 points Name the 3 extant orders of Amphibia. Answer • Caudata • Anura • Gymnophiona Reptiles 100 points Birds are monophyletic group whereas reptiles are ____________ group. Answer • Paraphyletic Birds 100 points 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? Answer • Myxini (hagfish) • As a defense mechanism- too large to swallow and digestion Amphibians 200 points Name the missing link that had a perfect mix of fish and amphibian features. Answer • Also known for having fin with wrists • Tiktaalik Reptiles 200 points What allowed reptiles to break the tie to water? For an extra 100 pts describe 3 features of this. Answer Birds 200 points • 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 300 points 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 300 points Explain the difference between endothermy vs homeothermy. 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 300 points • 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. Answer • Allows for less weight in the skull without sacrificing strength • Ability to attach more muscle to skull in a more efficient manner Misc. 300 points Which muscle type is associated with limbs, body core, and respiration? For an additional 50 pts name the other 2 muscle types. Answer • Skeletal muscles • Smooth and cardiac muscles Fish 400 points Describe the unique feature of the Ceratodontomorpha. Answer • During dry periods form cocoon, aestivate in mud Amphibians 400 points Name 3 predictions why amphibians moved to land. Answer Ocean becoming crowded Predation High Competitave Avoidance Food available on land Reptiles 400 points What is convergent evolution and provide an example Answer • The reoccurrence of a trait multiple times through time. • Example of four chamber heart in crocodiles and mammals Birds 400 points Name 4 characteristics for the evolution of flight to occur Answer Hollow Bones The reduction of gonads in off season Feathers Rapid digestion Mammals 400 points Describe the jaw articulation shift from reptiles to mammals. Answer • The shift from – Reptiles : articular/ quadrate articulation • Jaw used in minor role for hearing – Mammals : Squamosal/ dentary • The articular/ quadrate moved to the inner ear to aid in better hearing Misc. 400 points Name the 5 eras we discussed in class and what clade it corresponds with. Answer Devonian – Fish Carboniferous – Amphibians Mesozoic- Reptiles Cretaceous- Birds Cenozoic- Mammals Fish 500 points Name 3 characteristics of Osteichthyes Answer • • • • Skeleton of bone Thin, overlapping scales Paired fins Swim bladder - pouch derived from esophagus w/air volume regulated for buoyancy Amphibian 500 points Name 4 problems with the move to land Answer • Gravity – skeleton must now support weight • Locomotion – propulsion must change (more use of limbs) • Breathing – Oxygen more concentrated in air than water, but gills function poorly in air and desiccate quickly • Feeding – must use jaws, teeth, and tongue to secure food (suction feeding not sufficient) • Reproduction – eggs desiccate quickly • Outer covering – desiccation • Pumping blood (gravity constraints) Reptiles 500 points Name the 3 taxanomic groups within Squamata that are not monophyletic Answer Serpentes (Snakes) Amphisbaenia (worm lizards) Lacertilia (lizards) Birds 500 points Explain the ground up hypothesis and why it doesn’t work. Answer • • • • Cursorial Hypothesis II (ground-up hypothesis) Refined trees down hypothesis Wings used to catch prey out of air Wrong- For flight to occur lift and thrust is needed • less friction doesn’t allow more lift ex) car anology Mammals 500 points Explain the 3 rules of morphological variation in endotherms. Answer • Bergmann’s Rule – endotherms tend to be larger in colder climates • Allen’s Rule – extremeties of endotherms vary inversely w/body size • Gloger’s Rule – endotherms living in arid regions tend to be lighter in coloration Misc. 500 points Chronologically name the structures of an entire muscle. Answer • • • • • • Muscle cell Fascicle Micro Fibers Myofibrils Myofilaments Myosin and actin
