There are 4 steps in the natural selection mechanism. Which statement below is incorrect?

• Within a population of one species, there is genetic diversity, which is called variation.

• Due to natural variation, some individuals will be fitter than others.

• Fitter individuals have a disadvantage and will reproduce less successfully than individuals who are less fit.

• The offspring of fitter individuals may inherit the genes that give that advantage.
