Question #1
A Because selection does not produce new variants of traits
B Because selection can only make traits larger, not smaller
C Individuals can only change when they try to
D Because large changes are better than small increments of change when breeding by blending
Question #2
A Natural selection reduces variation in the trait.
B Natural selection acts by removing only variants of highest fitness.
C Natural selection does not actually remove any variants in real life.
D All of these statements are true.
Question #3

B beaks with large depth.
C beaks with random depth.
D beaks with medium depth

B was reluctant to publish his theories
C was not concerned with public opinion and did not mind if his theories were criticized
D published his theories as soon as he returned from his voyage on the Beagle
Question #6
A All of these statements are correct
B Faster gazelles are more likely to escape predators and survive long enough to produce offspring
C Predation from lions is a powerful selective pressure
D The ability to run fast is passed from gazelles to their offspring
Question #7
A many more small seeds were available for the finches to eat.
B more finches with deep beaks died than finches with shallow beaks.
C finches with shallow beaks were less likely to survive and reproduce than finches with deep beaks.
D finch beak size had no effect on survival rates.
Question #8
A groups
B families
C species
D individuals
Question #9
A age at death
B reproductive success
C strength
D aggressiveness
Question #10
A Species are unchanging types, and individual variation within a species is not important.
B There is competition among individuals for resources.
C Favorable variations are passed on and accumulate in populations over time.
D Population size increases more rapidly than food supplies.
Question #11
A the inheritance of acquired characteristics
B natural selection
C catastrophism
D uniformitarianism
Question #12
A there is no competition among individuals.
B traits are never inherited by offspring.
C no form of a trait is more advantageous than another because all individuals have exactly the same form.
D the one trait that exists is always advantageous, and change is not necessary.
Question #13
A variation is passed from parents to offspring.
B variation affects the ability of individuals to survive and reproduce.
C any given environment can support only a certain number of individuals.
D individuals always compete with each other physically.
Question #14
A heritable variation in organisms.
B bigger organisms surviving at a higher rate than smaller organisms.
C existing variation in organisms.
D the interaction of organisms with their environment.
Question #15
A claim that favorable variations would tend to be destroyed, unfavorable ones be preserved
B recognize the importance of biological variation within a population
C appreciate the fact that population size is limited by availability of food
D apply his knowledge of domesticated species to undomesticated ones
Question #16
A Is observed when an individual’s parents have different numbers of offspring
B Was first observed in a species of frog that lays an average of 2,000 eggs
C Is differences in average reproductive success between species
D Is differences in reproductive success between individuals of the same group
Question #17
A Is measured as the total number of sex partners over the life span
B Never happens for smaller individuals
C Was first observed in a species of frog that lays an average of 2,000 eggs
D Is the number of offspring who survive to an age at which they themselves can reproduce
Question #18

B received no formal education
C grew up in modest circumstances
D spent two years in Africa where he developed the theory of natural selection
