Explanation
Genetic drift is the change in frequency of an existing gene variant in the population due to random chance. the condition of having or being composed of differing elements is called diversity.

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.
