Unformatted text preview: aspects of the fish’s physiology or habitat can be labeled as the vehicles during the natural selection process. The nests, vibrant colors, and elaborate mating rituals are all “built” in some way by the DNA of the fish, which represents the replicator that is attempting to copy itself and ensure its survival. Overall, I think that the behavior and physiology of the fishes in Lorenz’s extract are actually used as vehicles by the DNA (which acts as the replicator in this case) to enhance the survival and reproduction of the genes within the fish. I find it hard to understand this theory of genes as replicators and the organisms as vehicles , but I think that reading these two articles have allowed me to better connect a real life example to what I am studying....
