13. 12 Which of the following can be considered an analogous structure: A The wings of butterfly & the wings of bats B The pectoral fins of ray-finned fish and the pectoral fins of cetaceans (dolphins/whales) C The hind legs of dogs and the hind legs of horses D The pectoral fin of a walrus & the pectoral fin of a dolphin

14. 13 Leopard frogs & Wood frogs live in close proximity to each other & will often mate. The resulting tadpoles only survive a few days prior to death. This is an example of: A Reduced hybrid fertility B Increased hybrid fertility C Reduced hybrid viability D Hybrid breakdown

15. 14 The sockeye salmon has one of nature's most dramatic generational migrations. They spend all of their life in the ocean & then migrate hundred of miles back to the streams in which they were born. This type of migration is called: A catadromous B anadromous C salt-to-fresh polyandrous migration D fresh-to-salt annual migration

16. 15 Action & reaction to stimuli defines A Brood parasitism B Fixed action patterns C False action patterns D Animal behavior

18. 17 All of the following are potential down sides of intelligence EXCEPT: A intelligence is calorically expensive B gestation of offspring is longer C intelligent organisms tend to be apex predators D offspring require more care from their parents/adults

19. 18 Corn (maize) originally appeared like a grassy bush, but over many thousands of generations mankind created the corn that is so widely used in the United States of today. This is an example of: A Natural Selection B Diversifying natural selection C Sexual Selection D Artificial Selection

22. 21 Which of the following is an example of founder effect: A A species of darker-colored mice survive predation from owls & falcons, causing the population as a whole to shift to a darker color. B A group of migratory birds stop on an island and never leave. They cease their migration & evolve into their own species. C A group of horses with long necks randomly survive a brush fire that wipes out much of the population. These long-necked horses eventually evolve into giraffes D A trolling net scoops up an entire school of anchovies, reducing the population by a small percent.

24. 23 Which of the following is an example of macroevolution: A Over many generations a species of mice gets darker in color due to predation from owls and falcons B Over many generations an off-shoot of catfish changes from a bottom-feeder to an aggressive hunter, no longer able to reproduce with the former catfish C Over many generations a species changes in size from large to small to better fit in with the environment D Over many generations a species of fish changes its scale color from yellow to blue

25. 24 Consider a coral reef in the Atlantic Ocean: a species of clown fish are known to live all throughout this reef. During fishing season a large trawling net smashes the reef into three small pieces, all of which are separated by a large distance. After many generations the clown fish on the three different sections of reef become different species. This is an example of: A Allopatric speciation B Sympatric speciation C Parapatric speciation D Convergent speciation
