B Individuals can only change when they try to
C Because selection can only make traits larger, not smaller
D Because selection does not produce new variants of traits
Question #2
A Natural selection reduces variation in the trait.
B Natural selection does not actually remove any variants in real life.

D was reluctant to publish his theories
Question #6
A The ability to run fast is passed from gazelles to their offspring
B Predation from lions is a powerful selective pressure
C All of these statements are correct
D Faster gazelles are more likely to escape predators and survive long enough to produce offspring
Question #7
A finch beak size had no effect on survival rates.
B many more small seeds were available for the finches to eat.
C more finches with deep beaks died than finches with shallow beaks.

D groups
Question #9
A strength
B reproductive success
C age at death
D aggressiveness
Question #10
A Favorable variations are passed on and accumulate in populations over time.
B Species are unchanging types, and individual variation within a species is not important.
C There is competition among individuals for resources.
D Population size increases more rapidly than food supplies.
Question #11
A natural selection
B uniformitarianism
C catastrophism
D the inheritance of acquired characteristics
Question #12
A no form of a trait is more advantageous than another because all individuals have exactly the same form.
B the one trait that exists is always advantageous, and change is not necessary.
C there is no competition among individuals.
D traits are never inherited by offspring.
Question #13
A individuals always compete with each other physically.
B variation affects the ability of individuals to survive and reproduce.
C any given environment can support only a certain number of individuals.
D variation is passed from parents to offspring.
Question #14
A bigger organisms surviving at a higher rate than smaller organisms.
B the interaction of organisms with their environment.
C existing variation in organisms.
D heritable variation in organisms.
Question #15
A recognize the importance of biological variation within a population
B appreciate the fact that population size is limited by availability of food
C apply his knowledge of domesticated species to undomesticated ones
D claim that favorable variations would tend to be destroyed, unfavorable ones be preserved

C Is differences in reproductive success between individuals of the same group
D Is observed when an individual’s parents have different numbers of offspring
Question #17
A Never happens for smaller individuals
B Is the number of offspring who survive to an age at which they themselves can reproduce
C Is measured as the total number of sex partners over the life span
D Was first observed in a species of frog that lays an average of 2,000 eggs
