Which of the following examples demonstrate an ecological effect leading to an evolutionary effect?
A) When seeds are not plentiful, trees produce more seeds.
B) A few individuals with denser fur survive the coldest years of an ice age, and the offspring of the reproducing survivors of the ice age will likely have more dense fur.
C) Fish that swim the fastest in running water catch the most prey and more easily escape predation.
D) The insects that spend the most time exposed to sunlight have the most mutations from UV light, and thus evolve the fastest

Quizplus · Accepted Answer

The survival of individuals with denser fur leads to a higher frequency of that trait in the population over time, which is an evolutionary effect resulting from an ecological effect (the ice age conditions selecting for denser fur). The other options describe ecological effects on survival or behavior, but not necessarily leading to evolutionary changes in the population over time.
