Natural selection can only select; the evolutionary force that creates novel traits is:

  1. Mutation
  2. Migration
  3. Drifting
  4. Breeding
Show answer and solution

Correct answer: A. Mutation

1. Selection cannot create. 2. Mutation supplies new traits. 3. Selection then acts on them. _Source: OpenStax Biology 2e, Chapter 19, The Evolution of Populations (CC BY 4.0)._
