BIO 152 EVOLUTION EXAM WITH
CORRECT ANSWERS 2025
Natural Selection is: correct answers >> a process leading to
differential reproductive successes among members of a
population
Cactus-like plants adapted for desert or dry environments are
succulent (have fleshy, juicy stems) and have spines (modified
leaves). Succulents can be found to occur around the world, but
are classified into a number of very different families of plants
based on other characteristics. That so many different kinds of
succulents exist is an example of: correct answers >>
convergent evolution
T/F: meiosis acting alone could change allele frequency correct
answers >> false
T/F: natural selection acting alone could change allele frequency
correct answers >> true
T/F: genetic drift acting alone could change allele frequency
correct answers >> true
What are the two major sources of genetic variation in a
population? correct answers >> mutation and recombination
T/F: evolution in a rapidly reproducing population can be faster
because the mutation rates per gene locus are faster in small
,populations compared to large populations correct answers
>> false
T/F: evolution in a rapidly reproducing population can be faster
because random events can have larger effects on allele
frequencies correct answers >> false
T/F: evolution in a rapidly reproducing population can be faster
because more reproductive events per unit time translates into
more possible changes per unit time correct answers >> true
T/F: the rate at which a particular kind of mutation occurs is
independent of the fitness of the resulting allele correct
answers >> true
Which condition of HW equilibrium is being violated? : In a
particular region of the coast, limpets (a type of mollusc) live on
near shore habitats that are uniformly made up of brown
sandstone rock. The principle predators of these limpets are
shorebirds. The limpets occur in two morphs, one with a light
colored shell and one with a dark colored shell. The shorebirds
hunt by sight and are able to see the light ones on the dark
sandstone easier than the dark ones. correct answers >> No
selection
Which condition of HW equilibrium is being violated? : In Chen
caerulescens (a species of goose), the white body form, the snow
goose and the blue body form, the blue goose, occasionally
coexist. In these areas of contact, white by white and blue by blue
matings are much more common than white by blue matings.
correct answers >> Random Mating
,Which condition of HW equilibrium is being violated? : Prior to the
Mongolian invasions which occurred between the 6th and 16th
centuries, the frequency of blood type B across Europe was close
to zero. The frequency of blood type B among the Mongols was
relatively high. Today, it is possible to see fairly high frequencies
of blood type B in the eastern European countries and a gradual
decrease in the frequency of blood type B as one moves from the
eastern European countries to the western Europe correct
answers >> No migration
T/F: Populations rather than individuals undergo evolution
correct answers >> true
T/F: Natural selection acts on individuals within a population
correct answers >> true
T/F: Natural selection is the only factor that can lead to evolution
correct answers >> false
T/F: Genetic drift (changes in allele frequencies due to chance
alone) should have a greater impact in small populations
correct answers >> true
Which of the following was true about Charles Darwin?
A. He believed that evolution was due to the inheritance of
acquired characteristics.
B. He supported Lamarck's explanation of how evolution occurred.
C. He observed that populations contain natural variation.
, D. None of the above. correct answers >> C
Which of the following was NOT part of Darwin's theory of
Evolution?
A. Natural Selection
B. Populations as the units of Evolution
C. Mutations as sources of genetic variation
D. Survival of those who produce more offspring correct
answers >> C
Founder of taxonomy correct answers >> Linnaeus
Believed that evolution from disuse of body parts and the
inheritance of characteristics correct answers >> Lamarck
Father of paleontology, opponent of evolution , extinctions occur -
but through many catastrophes that wipe out species correct
answers >> Cuvier
Uniformitarianism correct answers >> Earth changes
gradually, allowed time for evolution to occur
Early geologists - uniformitarianism correct answers >>
Hutton & Lyell
Believed that food supply grows linearly and population grows
exponentially correct answers >> Malthus
