RESUMO:

Cooperative and altruistic behaviors have, for a long time, intrigued biologists around the world due to their apparent evolutionary countersense. After all, it is a behavior that generates a benefit to another organism at the expense of its performer. Although it has already been investigated by many researchers, little emphasis has been given to the biological elements necessary for the evolution of such traits, and only recently this issue was been approached by microbiology when considering bacteria, fungi and protozoa; groups of great importance that play relevant role in public health, economics and philosophy of science. We propose to carry out a review of the main biological factors that allow the evolution and maintenance of this behavior in microorganisms. The literature analysis allowed to classify the models in six main categories: Environmental conditions; Conditional Gene Expression; Partial Privatization of Public Goods; Enforcement mechanisms; Cooperative Hitchhiking; and Dispersion & Growth Trade-offs. Many of these models become intertwined with others, and can act together to establish cooperative behavior. Among the factors found, the spatial structuring between cooperating and selfish organisms seemed to be particularly important, since it was observed in several different models. This research allowed a comprehensive and quite deep appreciation of cooperative behavior and its evolution among microorganisms, enabling new and more directed studies that seek to elucidate in what ways this behavior is maintained in natural microbial populations.
