Which of the following are postulates of Darwinism?

  1. Overproduction
  2. Struggle for existence
  3. Inherited variation
  4. All of the above

hintHint:

Darwin explained concepts like individuals who are competent can survive, more offspring are born than can survive and that no two individuals are identical.

The correct answer is: All of the above


    Charles Darwin explained mainly the following concepts:
    • Struggle for survival: Also called survival of fittest. Only those individuals that are competent can live in the environment.
    • Over production: More offspring are born than those can survive
    • Inherited variation: The variation is the difference in genetic makeup between individuals of the same species. Hence, no two individuals are similar, even the identical twins.
