Answer

Brief Explanations:

Random evolutionary processes are driven by chance events, not traits that improve fitness.

  • Option A: Earthquake splitting populations is random genetic drift.
  • Option B: Mutation is a random genetic change.
  • Option C: Winter shifting range is a random environmental event.
  • Option D: The tree mutation improves seed dispersal, increasing fitness and leading to non-random (adaptive) population growth, not a random process.

Answer:

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