What is coevolution? - CORRECT ANSWER-the influence of
closely associated species on each other in their evolution.each
species adapts to the presence of the other
True or False? A pair of species engaged in commensalism can
coevolve. - CORRECT ANSWER-False; only one member
receives a benefit.
T/F: Coevolution is the reciprocal evolution of two or more
species. - CORRECT ANSWER-true
T/F: Diffuse coevolution occurs when one species of plant
coevolves with one species of pollinator. - CORRECT
ANSWER-false

Which of the following observations most strongly supports the
hypothesis that ants and Acacia trees have experienced one-onone coevolution? - CORRECT ANSWER-The removal of either
trees or ants from the environment causes the extinction of the
remaining species.
T/F: Coevolution has important consequences for medicine
because pathogens coevolve with their hosts. - CORRECT
ANSWER-true
How can several species of dung beetles coexist? - CORRECT
ANSWER-There has to be something about their niches that
differ; if they both eat dung, it can't be what they eat, but there
has to be something else that keeps them from out-competing
one another; there has
to be some other resource that's limiting the one species from
getting all the dung.
True or False? If species of beetles have the same niche,
eventually all but one species will become extinct. - CORRECT
ANSWER-true
True or False? If species compete for many generations, natural
selection would cause their niches to diverge. - CORRECT
ANSWER-true

T/F: While spreading through the human population, the viral
population experiences one-on-one coevolution with the
population of humans. - CORRECT ANSWER-true,Coevolution
the hypothesis that when the virus and the host reciprocally
affect each other's evolution
T/F:When humans and viruses interact as host and pathogen,
respectively, an evolutionary change in one population will
result in selective pressure on the other population. - CORRECT
ANSWER-true
T/F: Viruses can become less harmful to humans through natural
selection in the human population or natural selection in the
viral population. - CORRECT ANSWER-true
T/F: If the immune system of humans evolves to reduce the
reproduction of viruses, the viral population would likely
experience the natural selection of viruses that are less harmful
to humans. - CORRECT ANSWER-false
T/F: The deadliest viruses for humans are likely to be ones that
have spent little time infecting the human population. -
CORRECT ANSWER-true
