I. Population evolve to maximise their reproductive fitness, also called Darwinian fitness (higher 'r' value) in the habitat in which they live II. The population growth rate r is inversely related to generation time III. The housefly , which has a short life span and produces a large number of eggs, could be considered as a K selected species IV. under a particular set of selection pressures, organisms evolve towards the most efficient reproductive strategies V. life history traits of organisms have evolved in relation to the constrains imposed by biotic and abitioc factors in their habitat.
