All of the choices are required for natural selection to occur in a population. Without variation in the population, there is no basis for selection. Without inheritance of variation through genetic differences, any selected traits could not be passed on to the next generation. Without differential reproduction, the adaptive traits would not be favored and would not increase in the population. And without the accumulation of adaptive traits, there would be no overall shift in the genetic makeup of the population over time.
