In developing his scientific theory of evolution by natural selection, Charles Darwin considered four main observations: heritable variation among individuals in a population, overproduction of offspring, limits on populationgrowth, and differential reproductive success. Compare how these observations may apply to populations that tend to fit the concepts of r selection and K selection
