The unequal ability of individuals to survive and reproduce will lead to a gradual change in a population, With favorable 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
The processes of natural selection thus cause an increase of favourable alleles and a decrease of unfavourable alleles within the population, Over succeeding generations, individual members become better adapted to local conditions, thus, leading to the evolution 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.
