These organisms that survive and reproduce, pass these beneficial traits onto their offspring. In other words: Natural selection is differential success in reproduction ( unequal ability of individuals to survive and reproduce). This unequal ability of individuals to survive and reproduce will lead to a gradual change in a population, with the inheritance of favorable characteristics accumulating over the generations. Those individuals whose inherited characteristics best fit them to their environment are likely to leave more offspring than less-fit individuals (= natural selection). Survival in the struggle for existence is not random, but depends in part on the hereditary constitution of the surviving individuals.
