Argument For Evolution
Test Description: Practice your understanding of natural selection and other evolution topics.
Instructions: Answer all questions to get your test result.
1) What is natural selection?
A
The mechanism that increases the chance of certain individuals reproducing.
B
The mechanism that leads to increasing variation within a population.
C
The cumulative change in the heritable characteristics of a population.
D
The mechanism that explains why populations produce more offspring than the environment can support.
2) What is natural selection?
A
Variation due to mutations in a population
B
Making a random choice of partner for reproduction
C
Increased reproductive success by those with favourable variation
D
The survival of the largest organisms in a population
3) Why has evolution resulted in antibiotic resistance in bacteria?
A
Bacteria resistant to the antibiotic survive to pass on this characteristic to their offspring
B
Bacteria change their metabolism to cope with the presence of antibiotics.
C
Not completing a course of antibiotics allows resistant bacteria to develop.
D
Bacteria have learnt how to neutralize the effects of the antibiotic and they pass this onto their offspring.
4) According to Darwin’s theory of evolution, what causes the struggle for survival in populations?
A
Overproduction of offspring
B
Favourable heritable variations
C
Natural selection
D
Competition between the fittest individuals in the population
5) Which process has the greatest effect in determining which members of a population are most likely to survive until reproductive age?
A
Meiosis
B
Hybridization
C
Natural selection
D
Evolution
6) During his voyage on the Beagle, Charles Darwin made many observations
A
on the Galápagos Islands.
B
in Asia.
C
in North America.
D
in England.
7) On the Galápagos Islands, Charles Darwin observed
A
species completely unrelated to those found in South America.
B
completely unrelated species on each of the islands.
C
species exactly like those found in South America.
D
somewhat similar species, with traits that suited their particular environments.
8) The species of finches that Charles Darwin found on the Galápagos Islands displayed different structural adaptations. One of the adaptations that Darwin noted was the
A
birds’ different-shaped beaks.
B
length of the birds’ necks.
C
number of eggs in each bird’s nest.
D
similarities of the birds’ embryos.
9) James Hutton’s and Charles Lyell’s work suggests that
A
all fossils were formed in the last 1000 years.
B
Earth is several thousand years old.
C
Earth is many millions of years old.
D
all rocks on Earth contain fossils.
10) Jean-Baptiste Lamarck proposed that organisms
A
inherit all of the adaptations they display.
B
have an innate tendency toward complexity and perfection.
C
belong to species that never change.
D
have an innate tendency to become simpler as time passes.
11) Which is a major concept included in Lamarck’s theory of evolution?
A
Change is the result of survival of the fittest.
B
Body structure can change according to the actions of the organism.
C
Population size decreases the rate of evolution.
D
Artificial selection is the basis for evolution.
12) In each generation, the wings of experimental fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. This observation would tend to disprove the idea that evolution is based on
A
natural selection.
B
inheritance of acquired characteristics.
C
inheritance of natural variations.
D
survival of the fittest.
13) In 1859, Charles Darwin published his revolutionary scientific ideas in a work titled
A
On the Origin of Species.
B
Principles of Geology.
C
Evolution in Malaysia.
D
Essay on the Principle of Population.
14) When farmers select animals or plants to use for breeding, they look for
A
natural variations that are present in a species.
B
traits that are produced artificially.
C
species that are perfect and unchanging.
D
homologous structures.
15) When a farmer breeds only his or her best livestock, the process involved is
A
natural selection.
B
survival of the fittest.
C
artificial selection.
D
artificial variation.
16) Which statement about the members of a population that live long enough to reproduce is consistent with the theory of natural selection?
A
They transmit characteristics acquired by use and disuse to their offspring.
B
They are the ones that are best adapted to survive in their environment.
C
They tend to produce fewer offspring than others in the population.
D
They will perpetuate unfavorable changes in the species.
17) In humans, the pelvis and femur, or thigh bone, are involved in walking. In whales, the pelvis and femur are....?
A
vestigial structures.
B
acquired traits.
C
examples of natural variation.
D
examples of fossils.
18) Modern sea star larvae resemble some primitive vertebrate larvae. This similarity may suggest that primitive vertebrates
A
evolved from sea stars.
B
belong to the same species as sea stars.
C
evolved before sea stars.
D
share a common ancestor with sea stars.

A
homologous structures such as wings and arms.
B
natural variations in a population.
C
descent with modification.
D
the same kind of embryos.
20) Which concept is NOT included in the modern theory of evolution?
A
natural selection
B
descent with modification
C
transmission of acquired characteristics
D
competition among the members of a population
