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

B Alfred Russel Wallace
C Jean-Baptiste Lamarck
D Charles Lyell
Question #5
A was reluctant to publish his theories
B was not concerned with public opinion and did not mind if his theories were criticized
C published his theories as soon as he returned from his voyage on the Beagle
D all of these statements are true
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 finch beak size had no effect on survival rates.
B finches with shallow beaks were less likely to survive and reproduce than finches with deep beaks.
C many more small seeds were available for the finches to eat.
D more finches with deep beaks died than finches with shallow beaks.
Question #8
A groups
B families
C individuals
D species
Question #9
A reproductive success
B strength
C age at death
D aggressiveness
Question #10
A Population size increases more rapidly than food supplies.
B Favorable variations are passed on and accumulate in populations over time.
C There is competition among individuals for resources.
D Species are unchanging types, and individual variation within a species is not important.
Question #11
A natural selection
B uniformitarianism
C catastrophism
D the inheritance of acquired characteristics
Question #12
A there is no competition among individuals.
B no form of a trait is more advantageous than another because all individuals have exactly the same form.
C traits are never inherited by offspring.
D the one trait that exists is always advantageous, and change is not necessary.
Question #13
A any given environment can support only a certain number of individuals.
B individuals always compete with each other physically.
C variation affects the ability of individuals to survive and reproduce.
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 heritable variation in organisms.
D existing variation in organisms.
Question #15
A apply his knowledge of domesticated species to undomesticated ones
B appreciate the fact that population size is limited by availability of food
C recognize the importance of biological variation within a population
D claim that favorable variations would tend to be destroyed, unfavorable ones be preserved
Question #16
A Is differences in reproductive success between individuals of the same group
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 observed when an individual’s parents have different numbers of offspring
Question #17
A Is the number of offspring who survive to an age at which they themselves can reproduce
B Was first observed in a species of frog that lays an average of 2,000 eggs
C Never happens for smaller individuals
D Is measured as the total number of sex partners over the life span
Question #18
A began to doubt the fixity of species during a voyage around the world in the 1830s
B grew up in modest circumstances
C spent two years in Africa where he developed the theory of natural selection
D received no formal education
