Below are the questions for the exam with the choices of answers:
Question #1
A Individuals can only change when they try to
B Because large changes are better than small increments of change when breeding by blending
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 does not actually remove any variants in real life.
B Natural selection acts by removing only variants of highest fitness.
C Natural selection reduces variation in the trait.
D All of these statements are true.
Question #3
A beaks with large depth.
B beaks with medium depth
C beaks with random depth.
D beaks with small depth.
Question #4
A Jean-Baptiste Lamarck

C Charles Lyell
D Alfred Russel Wallace
Question #5
A was reluctant to publish his theories
B all of these statements are true
C published his theories as soon as he returned from his voyage on the Beagle
D was not concerned with public opinion and did not mind if his theories were criticized
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 finches with shallow beaks were less likely to survive and reproduce than finches with deep beaks.
Question #8
A groups
B families
C species
D individuals
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 Population size increases more rapidly than food supplies.
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 catastrophism
C uniformitarianism
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 variation affects the ability of individuals to survive and reproduce.
B variation is passed from parents to offspring.
C individuals always compete with each other physically.
D any given environment can support only a certain number of individuals.
Question #14
A heritable variation in organisms.
B existing variation in organisms.
C bigger organisms surviving at a higher rate than smaller organisms.
D the interaction of organisms with their environment.
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 claim that favorable variations would tend to be destroyed, unfavorable ones be preserved
D recognize the importance of biological variation within a population
Question #16
A Is observed when an individual’s parents have different numbers of offspring
B Is differences in average reproductive success between species
C Is differences in reproductive success between individuals of the same group
D Was first observed in a species of frog that lays an average of 2,000 eggs
Question #17
A Never happens for smaller individuals
B Was first observed in a species of frog that lays an average of 2,000 eggs
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
A received no formal education
B grew up in modest circumstances
C spent two years in Africa where he developed the theory of natural selection
D began to doubt the fixity of species during a voyage around the world in the 1830s
