Which of the following examples of an ecological effect leading to an evolutionary effect is most correct?
A) When seeds are not plentiful, trees produce more seeds.
B) A few organisms of a larger population survive a drought and then these survivors emigrate to less arid environments.
C) A few individuals with denser fur survive the coldest days of an ice age, and the reproducing survivors of the ice age all have long fur.

This example shows that an ecological factor (the cold temperature during an ice age) led to an evolutionary change (the development of long fur in the survivors). The individuals with denser fur survived the cold environment and passed on their traits to their offspring, resulting in a new trait becoming more prevalent in the population.
