First, natural selection explains life’s amazing ability to adapt to different conditions. When observing different plants and animals, it is easy to become overwhelmed with their utter complexity. One can’t help but wonder why every detail is there. I always think about that species in the context of natural selection, and I reason how this certain trait helped the …show more content…
Diversity within the gene pool is critical to creating new combinations of alleles, each with the possibility to create a genetic advantage during certain conditions. Right now, natural selection within humans seems slow-moving. However, the real threats of a worldwide natural disaster or nuclear war would cause the process of natural selection will occur much more rapidly. To illustrate, if there is a worldwide outbreak of drug-resistant malaria, those who have sickle-cell anemia would be more likely to survive because of their level of resistance to the disease. Through natural selection, humans would evolve to have high rates of sickle-cell anemia as the species rebounded. The process of natural selection works such that continued existence of the species is the driving force, and genetic diversity is what allows this existence. Because of this, natural selection has taught be to appreciate diversity on both a human and genetic
