The key word in these processes is selection; when we have several clearly different options to decide upon, we look at the option we believe serves according to our best interest and “cull” the others. Artificial selection is the process of humans selecting certain phenotypes in organisms to serve their purpose. An example of artificial selection can be observed in the phenotypic diversity of dogs—which are the descendants of wolves, otherwise known as Canis lupus. Homo sapiens, with the aid of artificial selection, have been able to produce the number of dog breeds we currently have. On the contrary, natural selection is the natural (absolutely no human intervention involved in the process, aside from indirect) culling of organisms’ phenotype based on their environment—which includes climate, predators, and competitors; nature is who “decides” who dies and who lives to pass on their genes to their offspring and possibly successive generations. A prominent example of natural selection was observed in the population of Manchester, England’s peppered moth which had two distinctive phenotypes: one was dark and the other was light with dark spots. The dark moth constituted about one percent of the population in 1848—fast …show more content…
This drastic change in phenotype was due to the recent industrial age at the time, which killed the lichen moss found in trees that the light peppered moths camouflaged themselves with, and uncovered the dark
