In “The Theory of Natural Selection,” in The Theory of Evolution by John Maynard Smith, the idea of natural selection is that larger organisms come from simpler organisms. In this Darwin says that we all come from the same type of organisms by saying, “descended from a common ancestor: the birds and the bananas, the fishes and the flowers -- all related” (38). Creatures evolve from the simplistic ancestors naturally over a long period of time. So basically, random genetic mutations happen with an organism’s genetic code. This happens for natural selection, a survival aid for the organism. Over time this nation selection process turns into a new generation, and then eventually into an entirely different organism.
In my opinion, I believe that natural selection is real, Darwin explains how the larger things in life come from a lot of smaller things. For example, a family tree, its starts at the bottom with the two people, then gets bigger as it goes up as people reproduce. This is exactly what Darwin is saying about the organisms in natural selection. The same is true for the survival aid, as the generations go up the organisms get more and more adapted to their environment. So those are some examples why I believe that the natural selection theory is true.
