If an individual does not reproduce, then its degree of fitness is:
Correct answer: D. 0
- A. High
- B. Moderate
- C. Average
- D. 0
Explanation
Fitness in evolutionary terms is measured by the number of offspring that an individual produces that survive and reproduce themselves. If an individual does not reproduce, then it does not contribute to the next generation and therefore has a fitness of 0. This is true even if the individual is very well-adapted to its environment. If an individual cannot reproduce, then its adaptations are useless, and it will eventually die out of the population.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
