The best definition of natural selection is:
Correct answer: B. The most fit individuals adapt to their environment better than less fit individuals
- A. Survival of the fittest
- B. The most fit individuals adapt to their environment better than less fit individuals
- C. Those who eat better, arc healthier, and live longer are the most fit within a population
- D. Preservation of traits that lead to increased survival and reproduction
Explanation
Natural selection is the process by which organisms with traits that are better suited to their environment are more likely to survive and reproduce. This leads to the accumulation of adaptations over time and eventually to the formation of new species.

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.
