Darwin suggested that populations of individual species become better adapted to their local environments through:

Correct answer: D. Natural selection

  • A. Artificial selection
  • B. Adaptation
  • C. Variation
  • D. Natural selection

Explanation

Darwin suggested that populations of individual species become better adapted to their local environments through natural selection. This process involves the differential survival and reproduction of individuals due to differences in phenotype. Over time, this leads to the accumulation of beneficial traits in the population. Other options, like artificial selection, involve human intervention, and terms like "adaptation" and "variation" describe outcomes or components of the process rather than the mechanism itself.

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.
