Evolution Quiz %CODE1% Evolution In biological terms, what is a species? a group of organisms that are similar in form and structure a group of organisms that can interbreed a group of organisms that share common features a group of organisms that have live in the same habitat What is the Scala Naturae? an idea proposed by Darwin that suggests that all organisms share a common ancestor an idea proposed by Plato that suggests organisms are all evolving toward an ideal form an idea proposed by Aristotle that suggests that all organisms fit into an orderly scheme an idea proposed by Wallace that suggests that organisms change over time Creationism is not accepted as a valid scientific theory because: it violates the scientific principle of natural causality it doesn’t offer a model to explain the diversity of life on earth it cannot be disproven all of these The picture of the finches is used to illustrate: phylogeny of finches change over time specialization of beaks for different diets natural selection Which of the following was not an observation made by Darwin on his voyages: penguins use wings to paddle instead of fly snakes have rudimentary hind limbs the earth is very old islands had species that did not exist on the mainland The image illustrates: vestigial structures homologous structures the fossil record natural selection Which of the following is an example of artificial selection: a panda’s thumb the breeding of dogs the galapagos finches a giraffe’s neck According to the theory of evolution by natural selection, which of the following is true: random mating is necessary for evolution to occur variation does not exist between members of the same species populations will change to better fit their environment individuals will adapt to their environment Which of the following are assumptions made with regards to the Theory of Evolution by Natural selection organisms compete with each other to survive variations exist among organisms not all organisms that are born survive to reproduce all of these The image illustrates which of the following: artificial selection acquired characteristics homologous structures vestigial structures A panda’s thumb is considered an evolutionary contrivance because: it is assembled from wrist bones, and imperfect it is perfectly structured to grab leaves it is an structure that has no use none of these Which of the following outcomes would you predict for a population of bacteria exposed to a new antibiotic. over many generations, the bacteria would become resistant to the antibiotic over a few generations, the bacteria would evolve into Archaebacteria over a few generations, the bacteria would become extinct over many generations, the bacteria would become more susceptible to the antibiotic Which of the following is an example of convergent evolution: whales and sharks have similar body designs bees and hummingbirds have similar body designs bats and birds have similar body designs all of these Why is evolution called the “unifying theory of biology” because it explains the diversity of life on the planet because it serves as a model to predict how organisms will change it serves as a model to interpret relationships between organisms on the planet all of these The image illustrates how peppered moths are related to other moths how peppered moths adapted to a changing environment how peppered moths became extinct how peppered moths became two species Check Answers
