Question #1
A Individuals can only change when they try to
B Because selection does not produce new variants of traits
C Because large changes are better than small increments of change when breeding by blending
D Because selection can only make traits larger, not smaller
Question #2
A Natural selection does not actually remove any variants in real life.
B Natural selection acts by removing only variants of highest fitness.
C All of these statements are true.
D Natural selection reduces variation in the trait.
Question #3
A beaks with large depth.
B beaks with medium depth
C beaks with random depth.
D beaks with small depth.
Question #4

Question #5
A published his theories as soon as he returned from his voyage on the Beagle
B all of these statements are true
C was not concerned with public opinion and did not mind if his theories were criticized
D was reluctant to publish his theories
Question #6
A Faster gazelles are more likely to escape predators and survive long enough to produce offspring
B The ability to run fast is passed from gazelles to their offspring
C Predation from lions is a powerful selective pressure
D All of these statements are correct
Question #7
A finches with shallow beaks were less likely to survive and reproduce than finches with deep beaks.
B finch beak size had no effect on survival rates.
C more finches with deep beaks died than finches with shallow beaks.
D many more small seeds were available for the finches to eat.
Question #8
A families
B species
C individuals
D groups
Question #9
A aggressiveness
B reproductive success
C age at death
D strength
Question #10
A There is competition among individuals for resources.
B Favorable variations are passed on and accumulate in populations over time.
C Population size increases more rapidly than food supplies.
D Species are unchanging types, and individual variation within a species is not important.
Question #11
A natural selection
B the inheritance of acquired characteristics
C catastrophism
D uniformitarianism
Question #12
A the one trait that exists is always advantageous, and change is not necessary.
B traits are never inherited by offspring.
C there is no competition among individuals.
D no form of a trait is more advantageous than another because all individuals have exactly the same form.
Question #13
A variation is passed from parents to offspring.
B any given environment can support only a certain number of individuals.
C individuals always compete with each other physically.
D variation affects the ability of individuals to survive and reproduce.
Question #14
A existing variation in organisms.
B bigger organisms surviving at a higher rate than smaller organisms.
C the interaction of organisms with their environment.
D heritable variation in organisms.
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 apply his knowledge of domesticated species to undomesticated ones
D appreciate the fact that population size is limited by availability of food
Question #16
A Is differences in reproductive success between individuals of the same group
B Is differences in average reproductive success between species
C Is observed when an individual’s parents have different numbers of offspring
D Was first observed in a species of frog that lays an average of 2,000 eggs
Question #17
A Was first observed in a species of frog that lays an average of 2,000 eggs
B Never happens for smaller individuals
C Is measured as the total number of sex partners over the life span
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 began to doubt the fixity of species during a voyage around the world in the 1830s
D spent two years in Africa where he developed the theory of natural selection
