With age, all animals of any kind (or a large majority of individuals of most species), a period when the efficiency of distribution of their own genes decreased significantly - at times (the coefficient K is reduced to 2 or more times). Individual ceases to be the most efficient distributor of their own genes. Consequently, the selection can not shape the adaptive features that improve the spread of identical genes, ie, decreasing the fitness of an individual in favor of inclusive fitness. Natural selection would be most conducive to these signs, which action would be most correlated with the specific information coming to his senses. Scheme of the reaction of self-restraint in principle coincides with the scheme of the reactions of distress. Probably more correct to assume that the last stage of stress - distress for which there is a sharp reduction in body resistance, not the stage of exhaustion, and the stage of self-restraint. In favor of the fact that the reaction of distress (or one of its components) is a reaction of self-restraint, show all those ever conducted research and experiments, which showed that the reaction of distress, even leading to complete loss of viability depended on the coming to consciousness of information . This is also the experiments, which showed that there are some mechanisms of consciousness that can block or unblock the body's internal reserves. It's all those experiments, which showed that, other things being equal, that of the individuals has a better chance of survival, which has received information (real or false), that her chances of survival above - that is, which is more faith in the success of . What is meant here by distress? Definition, in principle no different from "classic": a distress implied response of the body, which, against the backdrop of a significant, repeated reduction of fitness of the organism (as noted above - not necessarily with a proportional decrease in viability) even more significantly, dramatically reduces fitness (including , viability). As you can see, the reaction of self-restraint of the body in a state of "selective unprofitable, will not differ from the reaction of distress. In the process of evolution on formirovaenie reactions of self-restraint will influence selection for reciprocal (mutually) altruistic traits. The problem of altruism in favor of unrelated individuals in evolutionary biology known as the problem of group (social group) otbora.Po this issue there is no consensus (lit. № 1,3,4,6,8,9,10,11,13). This problem was studied by means of mathematical M. Smith (literature number 9, and TZ № 10,11.) It was found that "selection for social behaviors can take place only under severe restrictions on the isolation of subpopulations, and impossible with any degree of population benefits, with a completely random mating.
