| | Fisher's fundamental theorem of natural selection |
 | | From this formulation there grew the misinterpretation that the fundamental theorem deals with an overall increase in the average Malthusian parameter of a population (e.g., Wright, 1930, 1955; Li, 1955; Kempthorne, 1957; Crow and Kimura, 1956; Kimura, 1958, 1965; Kojima and Kelleher, 1960; Ewens, 1969). |
 | | It is only when the organism lives in a density independent environment that the fundamental theorem seems to hold as a general principle. |
 | | At this limit the theorem defines a law of hyper-exponential increase in the population abundance (Witting, 2000b); a law that includes the Malthusian law of exponential increase (Malthus, 1798) as the special case with no evolutionary potential. |
