- In biological terms, what is a species?
Your answer:
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
Your answer:
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:
Your answer:
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:
Your answer:
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:
Your answer:
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:
Your answer:
vestigial structures
homologous structures
the fossil record
natural selection
- Which of the following is an example of artificial selection:
Your answer:
a panda's thumb
the breeding of dogs
the galapagos finches

- According to the theory of evolution by natural selection, which of the following is true:
Your answer:
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
Your answer:
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:
Your answer:
artificial selection
acquired characteristics
homologous structures
vestigial structures
- A panda's thumb is considered an evolutionary contrivance because:
Your answer:
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.
Your answer:
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:
Your answer:
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"
Your answer:
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
Your answer:
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
