Evolution

1. 1. 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
      
   2. 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
      
   3. 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
      

1. 1. The picture of the finches is used to illustrate: phylogeny of finches
      change over time
      specialization of beaks for different diets
      natural selection
      
   2. 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
      

1. 1. The image illustrates: vestigial structures
      homologous structures
      the fossil record
      natural selection
      
   2. 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
      
   3. 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
      
   4. 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
      

1. 1. The image illustrates which of the following: artificial selection
      acquired characteristics
      homologous structures
      vestigial structures
      
   2. 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
      
   3. 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
      
   4. 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
      
   5. 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
      

1. 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
