Biology 2343 Exam 1 Evolution Unit Name Multiple Choice please read carefully choose the single best answer 1 Which of the following terms refers to a mechanism by which microevolution of a population could occur a gene flow b genetic drift c natural selection d mate choice e all of the above 2 Which of the following terms does not describe a de ning characteristic of life a homeostasis b metabolism c response to environmental stimuli d sexual reproduction e heredity 3 Name the scientist who discovered evidence of extinctions in the fossil record a AR Wallace b Georges Cuvier c James Hutton d JeanBaptiste Lamarck e Thomas Malthus A feral population of labrador retriever dogs has two possible coat colors black and brown There are 100 dogs in the population 30 are homozygous for the black allele BB 20 are black heterozygotes Bb 50 are brown bb 4 Calculate the frequency of the black B allele a 20 b 30 c 40 d 50 e 60 5 Calculate the average heterozygosity for this population a 12 b 13 c 14 d 15 e 110 6 Four years from your initial survey you find that the frequency of the brown allele is 70 With respect to the allele for coat color has microevolution occurred a yes b no 7 Ten years from your initial survey five labrador retrievers emigrate from your population They join up with a population of feral beagles and begins to interbreed with them Which term best describes this event a prezygotic barrier b mutualism c gene flow d inbreeding e intersexual selection Matching Please select the most appropriate answer for each 8 imagine that Hobbits and humans have been living on separate continents for so many generations that they cannot produce offspring together 9 imagine within a population that over time Hobbits with a aHOpatr39C SpeC39atlon mediumsized feet predominated while those with large or small feet became rare b directional selection 10 imagine that within a population over time Hobbits with large feet became common in a population while those with small feet became rare c cline d stabilizing selection 11 imagine that within a population over time Hobbits with large or small feet became common while those with mediumsized feet became rare 9 d39VerS39fY39ng disruptive selection 12 imagine that Hobbits from lower altitudes are almost as tall as humans while Hobbits from mountain populations tend to be shorter and shorter with increasing altitude Polar Asiatic American Sun Sloth Spectacled Giant Lesser Brown bear bear black bear black bear bear bear bear panda Raccoon panda Pleistocenel Pliocenel 10 15 Miocene 20 25 Mllllons of years ago Oligocene Common ancestral 4 carnivorans Multiple Choice please read carefully choose the single best answer according to the associated illustration 13 According to the phylogeny above name the closest living relative to the lesser panda a brown bear b spectacled bear 0 giant panda d raccoon 14 According to the phylogeny above when did the procyonid clade diverge from the ursid clade a during the Milocene b 30000 years ago 0 10 million years ago d 30 million years ago 15 From this illustration one might conclude that a shared derived character defining the procyonid clade includes a the presence of fur b fur with brown pigment c a long tail d all of the above 16 Based on morphological and molecular data each specimen above belongs to a different troll species Consider carefully the appearance of the adult specimen here pictured for troll species Given its small stature and other aspects of a typically juvenile appearance it seems likely that over many generations mutations in homeotic genes have been associated here with an evolutionary trend called a gene flow b polymorphism cneoteny dconvergentevoution e stabilizing selection Matching Please select the most appropriate answer for each ie the narrowest category that fits 17 Animal clade with bilateral symmetry and no vertebral column some members clams snails 18 19 20 21 have a calcified shell Other members octopus squid have lost the shell Dinosaurs birds snakes dogs horses primates belong to this clade we have certain terrestrial adaptations not found in our moistureloving cousins the frogs and salamanders The landdwelling descendants of lobefinned fish include amphibians reptiles and mammals Animal clade with bilateral symmetry and no vertebral column characterized by their exoskeleton and jointed appendages Some are aquatic shrimp crab Others are terrestrial insects arachnids This clade includes animals with a vertebral column jawless and jawed fishes with and without ossified quotbonyquot skeletons as well as a few quotwormquot cousins such as Amphioxus the lancelet a arthropod b mollusk c chordate d tetrapod e amniote Matching Please select the most appropriate answer for each 22 23 24 25 26 27 28 29 the founder effect and the bottleneck effect are both examples of this phenomenon an unusually high rate of speciation leads to a large variety of different life forms within a relatively short time bacteria don t have multicellular bodies but they do communicate with chemicals to count their population size and behave accordingly relative reproductive success in the context of natural selection is called the chromosomal mutation called polyploidy has led to the evolution of two distinct species of gray tree frog adaptations which serve to prevent accidental hybridization between species the specific negative consequences of accidental attempts at hybridization between species are called through selective breeding humans have produced many useful varieties of livestock horses cows pigs sheep goats that have little in common with their wild ancestors a quorum sensing b artificial selection c sympatric speciation d fitness e prezygotic barriers ab postzygotic barriers ac adaptive radiation ad genetic drift True or False Choose a True or b False 30 31 32 33 34 35 Female choice often results in aggressive males with large body size and tusks horns antlers etc while male competition results in glamorous male physical characteristics such as the tail of the peacock All eukaryotes have multicellular bodies Members of the clade called quotFungiquot are absorptive heterotrophs The rst land plants did not have vessels seeds or flowers Ardipithecus ramidus 39Ardi39 was a bipedal ape with a large brain case and stone tools Her species lived in a grassland habitat where trees were few and far between Homo neanderthalensis went extinct before the appearance of modern humans in the fossil record 5amp 139 lGEiESa39L ION 11m 3111
