Worked practice questions

Darwin's three principles behind natural selection: traits are inherited, more offspring are produced than survive, and:

  1. Offspring vary
  2. Species are fixed
  3. Traits are acquired
  4. Habitats never change
Show answer and solution

Correct answer: A. Offspring vary

1. Variations among offspring are inherited. 2. Offspring vary in their characteristics. 3. Better competitors leave more offspring. _Source: OpenStax Biology 2e, Chapter 18, Evolution and the Origin of Species (CC BY 4.0)._

  3. Adam Smith
  4. David Ricardo
Show answer and solution

Correct answer: B. Thomas Malthus

1. Malthus wrote about human populations. 2. Reproduction outstrips resources. 3. This drives competition each generation. _Source: OpenStax Biology 2e, Chapter 18, Evolution and the Origin of Species (CC BY 4.0)._
