The unequal ability of individuals to survive and reproduce will lead to a gradual change in a population, with favourable characteristics accumulating over the generations, thus leading to the?
Correct answer: B. Evolution of new species.
- A. Struggle for existence.
- B. Evolution of new species.
- C. Overpopulation
- D. Persistence of species.
Explanation
Natural selection results in the accumulation of favourable traits in a population. Over generations, these adaptations can lead to significant changes in the population, ultimately resulting in the evolution of new species. The incorrect options either misinterpret the process or outcome of natural selection. The 'struggle for existence' is a mechanism in the process, not an outcome; 'overpopulation' is unrelated to trait accumulation; and 'persistence of species' does not specifically address 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.
