Longevity: “Replicators of high longevity would therefore tend to become more numerous and, other things being equal, there would have been an ‘evolutionary trend’ towards greater longevity in the population of molecules.” (Pg. 17 The Selfish GeneDefinition: Noun. Length or duration of life



   Evolution: “Evolution is something that happens, willy-nilly, in spite of all the efforts of the replicators (and nowadays of the genes) to prevent it happening.” (Pg. 18 The Selfish GeneDefinition: noun. Change in the gene pool of a population from generation to generation by processes such as mutation, natural selection and genetic drift





Competition:  “We can now see the less that less-favored varieties must actually become less numerous because of competition, and ultimately many of their lines must have gone extinct” (pg.19 The Selfish GeneDefinition: noun. The act of competing, rivalry for supremacy, survival.
