How would you describe the four key principles of natural selection?

Answer:
Four observations can be made to describe natural selection;

  1. Members of a population vary greatly in their traits.
  2. Traits are inherited from parents to their offspring.
  3. All species can produce more offspring than the environment can support.
  4. Not all offspring survive, due to limiting resources.

From those observations, two inferences can be made;

  1. Individuals with inherited characteristics that increase their probability of survival and reproduction will have more offspring.
  2. Favourable traits accumulate in the population as individuals have an unequal ability to reproduce.
