BSC 2005 Lecture Quiz Module 10: 1.) According to the Linnean hierarchy, which of the following is NOT in the correct order? Kingdom Animalia, Phylum Chordata, Class Mammalia Class Mammalia, Species Canis, Genus Lupus Class Mammalia, Order Carnivora , Family Felidae Family Hominidae, Genus Homo, Species sapiens According to binomial nomenclature, the genus and species of a name is always: written in Latin and upper case letters written in Swedish and in italics written in Latin and in italics written in lower case letters entirely Which of the following is the correct representation of binomial nomenclature? genus species Genus species Genus species Genus species Cichlids living in Lake Tanganyika have diversity relative to other groups living in similar sized lakes. high average low The diversification of Darwin's finches throughout the Galapagos exemplify which of the following? adaptive radiation parasitism Wallace's Rule taxonomy When there are a lot of available ecological niches, it is not uncommon to see: adaptive radiation migration extinction none of the above The continents are in the same locations that they were 245 million years ago. True False Which of the following would NOT be an example of convergent evolution in diet? meat-eating in a lion and meat-eating in a tiger great white shark eating seals and a killer whale eating seals nectar feeding by a butterfly and nectar feeding by a hummingbird plant-eating by a koala and plant-eating by a panda What percentage of identified LIVING species are vertebrates? 50 % 23 % 6 % less than 3% The science of naming organisms and classifying them into groups is termed: systematics phylogenetics taxonomy none of the above Which of the following is MORE inclusive (includes more taxa?) Phylum Order Family Class Earth's weather patterns and climate can be affected by changes in the planetary crust under the ocean. True False If you were a scientist and wanted to build a phylogeny for toucan birds, which type of information could you use? DNA sequences skulls of all the birds you want to include on your tree data on foraging behavior, songs and diet A and B only A, B and C Question 14 1 / 1 pts With binomial nomenclature, what two levels are included in an organism's name? genus and species class and species class and genus phylum and species If scientists have identified about 1.8 million living species, how many more are believed to be living that have not yet been identified? 5,000-30,000 500,000 - 3,000,000 4,000,000-30,000,000 300,000,000 - 400,000,000 A graphical (picture/graphic/drawing) representation of the relationships between species is termed: systematics a phylogeny taxonomy illustration The diversity of plants may be immeasurable since they occupy nearly every habitat on earth. True False Why did Linneus's innovation of "binomial nomenclature" revolutionize the field of taxonomy? species' common names are no longer confusing every species has a unique name based on its genus and species English is the language most scientists speak Hierarchy is not helpful when trying to understand relationships The majority of organisms on this planet that have been identified and classified are: ??? plants animals protists bacteria Which of the following is NOT a drawback of using DNA to determine relationships among species? expensive many thousands of characters cannot use on fossils some taxa are not available for sampling In phylogenetics, sister groups (properly defined): are the branches located next to each other on a tree share a most recent common ancestor have the same mitochondrial DNA look identical Similarities between organisms early in development (e.g. before birth or hatching) tell us nothing about their evolutionary history. True False Which of the following is NOT expected to affect species diversity? competition predation climate all of the above will affect species diversity The majority of species on earth are: vertebrates mammals invertebrates bacteria The fossil record shows clear evidence for gradualism, but punctuated equilibrium is merely a theoretical possibility and has not been demonstrated. True False
