Of the following examples of ecological effect leading to an evolutionary effect (→), which is most correct?
A)When seeds are not plentiful → trees produce more seeds.
B)A few organisms of a larger population survive a drought → these survivors then emigrate to less arid environments.
C)A few individuals with denser fur survive the coldest days of an ice age → the reproducing survivors all have long fur.
D)Fish that swim the fastest in running water → catch the most prey and more easily escape predation.
E)The insects that spend the most time exposed to sunlight → have the most mutations.

This example shows natural selection in action. Individuals with denser fur were better able to survive and reproduce during the ice age, passing on their advantageous trait to their offspring. Over time, the population evolved to have longer fur overall. The other examples do not necessarily involve genetic changes or selection pressures on a population.
