They converted carbon dioxide to oxygen. The increased oxygen levels allowed for cellular respiration to occur instead of only glycolysis. The atmosphere became thinner, decreasing temperatures of the planet as well.
The answer is <span>Without genetic diversity, natural selection cannot occur.
</span>In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. In order for natural selection to occur, the genetic diversity must be present within the population. That way, natural selection will have more "choices" so it can favor those variations t<span>hat will increase the chance of survival and reproduction.</span>
