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.
