Answer

Brief Explanations:

Random evolutionary processes are driven by chance events, not traits that improve survival/reproduction.

  • Option A: Earthquake is a random geographic barrier.
  • Option B: Mutations are random genetic changes.
  • Option C: Long winter is a random environmental event.
  • Option D: The mutation gives a reproductive advantage (wider seed spread) leading to population growth, which is natural selection—a non-random process favoring beneficial traits.

Answer:

D. a mutation results in a population of trees that spread their seeds more widely than their peers, causing their population to grow.
