What is evolution?
a.
b.
c.
d.
An inherited characteristic
harmful change in genetic information
when an animal or plant changes
When populations of organisms change over
time
• Darwin’s theory has 2 parts: (1) The ability of
an organism to survive and reproduce in its
natural environment is called
A.
B.
C.
D.
evolution
fitness
natural selection
use and disuse
• Part (2) of his theory, Common Descent with
modification, is when
A. Each living species has descended, with changes,
from other species over time
B. Individuals at the upper and lower ends of a
curve have the highest fitness
C. Small groups migrate to isolated new places
D. Two populations are separated by geographic
barriers
• The diagrams below show changes in a desert
lizard population.
Which biological concept is illustrated (in the lizard picture on the last
page)?
A. polygenic traits
B. natural selection
C. sex-linked inheritance
D. silent mutations
A group of squirrels were living together in the same forest. Because of an
earthquake the forest was split into two separate forests divided by a large,
rapid river. Squirrels were separated equally between the two different
forests. Millennia later these two populations of squirrels were two different
species. Which of the following would be the most plausible explanation?
A. Artificial selection has occurred because the environmental pressures for
the first group of squirrels was different than those for the second
B. Evolution has occurred because squirrel populations diverged over time
C. Evolution has occurred because the squirrels became more complex over
time
D. Ionizing radiation from the sun has caused mutations in one group of
squirrels
E. Random mating has occurred because there were half as many squirrels
to mate with
• The pictures below show bone structures in three animals.
What does the similarity in structure of the bones of these animals suggest?
A. the chemical make-up of these animals is exactly the same.
B. the size of these bones is the same.
C. these species developed at the same time and location.
D. these species share common ancestors.
• The drawings below show a turtle embryo and a
chicken embryo.
• Which of the following statements is supported
by the similarities between these embryos?
• A. The turtle is more advanced than the chicken.
B. The chicken has more offspring than the
turtle.
C. The turtle and the chicken are similar as
adults.
D. The chicken and the turtle share a common
ancestor.
• Porcupine quills, plant photosynthesis, and
wolves hunting in packs are all examples of
A.
B.
C.
D.
E.
Adaptations
Fitness
Genetic mutations
Natural selection
Survival of the fittest
• What didn’t Darwin know about that could
have helped him understand his theory
better?
A.
B.
C.
D.
E.
Genetics
Geology
Oceanography
Plant science
World geography
• What is the best description of a population?
A. A group of a single species that can have
offspring
B. A group of a single species that can interbreed
and produce fertile offspring
C. All the living and non-living factors in the
environment
D. Several species in a geographic area
