1. Compared to other developed countries, where did the United States rank when it’s citizens were asked if they thought that humans evolved from other species of animals?
at the top (majority accept that humans evolved from other animals)
in the middle (about 50% accept that humans evolved from other animals
at the bottom (a minority accept that humans evolved from other animals

at the bottom (a minority accept that humans evolved from other animals

2. Natural selection is the process component of the theory of evolution and descent with modification is the pattern component
true
false

True

3

3. The evolution of lactose tolerance in two different human groups is an example of:
unequal crossing over
gene duplication
non-disjunction
convergent evolution

convergent evolution

4

4. Which of the following pairs of structures are homologous with one another?
a bird wing and an insect wing
a bat wing and a human arm
a dolphin dorsal fin and a dorsal fin of a shark

a bat wing and a human arm

5

5. The DNA sequence of the human cytochrome c oxidase gene is more similar to the DNA sequence in a pig compared to the cytochrome c oxidase gene in a fish. This is because:
mammals require a similar cytochrome c oxidase gene relative to fish
humans and pigs share a more recent common ancestor than either does with a fish
the similarity between human and pig cytochrome c oxidase genes is due to chance
the similarity between human and pig cytochrome c oxidase genes is due to convergent evolution

humans and pigs share a more recent common ancestor than either does with a fish

6. Which of the following statements about the meaning and implications of the “great chain of being” is NOT correct?
a ladder-like hierarchy of non-living and living things
species were capable of changing
species were created by God

species were capable of changing

7. According to Darwin, the plants and animals found on the Galapagos islands were most similar to those:
found on other tropical island archipelagos he had visited
found in Africa
found in South America
found in Europe

found in South America

8. Natural selection acts on ________________, but _______________ evolve
genotypes, phenotypes
phenotypes, individuals
populations, individuals
individuals, populations

individuals, populations

9

9. The ability of an individual to pass on its alleles to offspring relative to other individuals in the population is referred to as:
adaptation
natural selection
fitness
convergent evolution

fitness

10

10. Two scientific criticisms of Darwin’s theory of evolution were put forth shortly after Darwin’s proposed descent with modification as a result of natural selection to explain how life evolved. One criticism had to do with blending inheritance, and the other involved?
how genes passed on genetic information
the age of the Earth
Biblical accounts of the creation
difficulties observing speciation

the age of the Earth

11. How would it be possible to have a daughter with a X-linked trait?
the father had the trait and the mother did not
the mother had the trait and the father did not
the father had the trait and the mother was heterozygous for the trait

the father had the trait and the mother was heterozygous for the trait

12

12. In terms of possible phenotypes, multi-genic traits typically approximate:
a 9:3:3:1 ratio
a 2:1 ratio as in blending inheritance
a 3:1 ratio
a 9:16:3:3:1 ratio
a bell-shaped curve

a bell-shaped curve

13

13. Suppose a man with type A blood marries a woman with type B blood. The first child they have has blood type AB. If they were to have more children what other blood types are possible?
only blood type AB is possible
A or B
A, B or O
O

A, B or O

14

14. Why were fossils problematic for those who believed that God specially created every living species found on Earth?
Fossil organisms represent life forms that have gone extinct, but God was supposed to create perfection
Fossils typically do not represent extinct organisms, so there is no problem
The presence of fossils meant that the Earth was much older than Lord Kelvin estimated

Fossil organisms represent life forms that have gone extinct, but God was supposed to create perfection

15. When Geologists examine strata (layers of rock), the deeper strata are:
less complex
older
more complex
younger

older
