AP Bio: Evolution Exam Questions &
Answers (Grade A+)
During a study session for evolution, one of your fellow students
remarks. "The giraffe stretched its neck while reaching for higher
leaves; its offspring inherited longer necks as a result." Which
statement is most likely to be helpful in correcting this student's
misconception?
A) characteristics acquired during an organism's life are generally
not passed on through genes.
B) spontaneous mutations can result in the appearance of new
traits.
C) only favorable adaptations have survival value.
D) disuse of an organ may lead to its eventual disappearance.
E) if the giraffes did not have to compete with each other, longer
necks would not have been passed on to the next generation. -
correct answer ✅A
Natural selection is based on all of the following except
A) genetic variation exists within populations
B) the best-adapted individuals tend to leave the most offspring
C) individuals who survive longer tend to leave more offspring than
those who die young.
D) populations tend to produce more individuals than the
environment can support.

E) individuals adapt to their environments, and thereby evolve -
correct answer ✅E
Which of the following represents an idea that Darwin learned from
the writings of Thomas Malthus?
A) technological innovation in agricultural practices will permit
exponential growth of the human population into the foreseeable
future.
B) populations tend to increase at a faster rate than their food
supply normally allows.
C) Earth changed over the years through a series of catastrophic
upheavals.
D) the environment is responsible for natural selection.
E) Earth is more than 10,000 years old. -
correct answer ✅B
A biologist studied a population of squirrels for 15 years. During
that time, the population was never fewer than 30 squirrels and
never more than 45. Her data showed that over half of the squirrels
born did not survive to reproduce, because of both competition for
food and predation. In a single generation, 90% of the squirrels that
were born lived to reproduce, and the population increased to 80.
Which inference(s) about this population might be true?

Answers (Grade A+)
A) the amount of available food may have increased.
B) the parental generation of squirrels developed better eyesight
due to improved diet; the subsequent squirrel generation inherited
better eyesight.
C) the number of predators that prey upon squirrels may have
decreased.
D) A and C could be true.
E) A, B, and C could be true. -
correct answer ✅D
The role that humans play in artificial selection is to
A) determine who lives and who dies
B) create the genetic variants, which nature then selects
C) choose which organisms breed, and which do not
D) train organisms to breed more successfully
E) perform artificial insemination -
correct answer ✅C
In a hypothetical environment, fishes called pike-cichlids are visual
predators of algae-eating fish (in other words, they locate their prey
by sight). If a population of algae-eaters experiences predation
