Recent developments using DNA data from Drosophila melanogaster show that natural selection is pervasive to an This document discusses different types of symbiotic relationships between microorganisms such as mutualism, commensalism, neutralism, and parasitism. the theory that some changes in evolution are governed by random mutations that become fixed in populations by chance rather than by natural selection. It is one of the symbiotic relationships occurring in nature. The strong programme adopts a position of relativism or neutralism regarding the arguments that social actors put forward for the acceptance/rejection of any technology. It then provides numerous examples of mutualistic relationships between species, including pollination mutualisms between plants and animals, seed dispersal mutualisms, protection mutualisms, and nutrient acquisition mutualisms.
