Therefore the selection will go ...

Therefore the selection will go on the most effective ways (mechanisms) identification of "gene selfishness" and "altruism gene" - this will increase the fitness of the genotype. In the scheme selection for reciprocal altruism, given in the book of R. Dawkins, considered the only way such an identification (recognition of "selfish genes" and "altruism gene"): individual donor donates a resource in the amount of X, and later remembers those who responded the feeling, those who gave her the resource X, which for this individual, as a recipient already has risen to a value of NX. Minimum critical size at which genes are reciprocal altruism will spread, calculated on the basis of the amount of potential losses (the sum of x's) in favor of selfish, and possibly winning NX, as a recipient. But there may be other ways of determining the level of true altruism in individuals, minimizing the loss in favor of "egoist" (or in favor of an egotist that mimic altruism). One such method - is determining the level of true altruism in individuals largest N, which is capable of this specimen, as a donor. If the individual perceives another individual as the bearer of the coefficient of relatedness r, equal to, for example 1 / 8 (ie, as a cousin), then any service (a victim of X) it will be ready to provide it free of charge if this service will have to relative value of the recipient, more than 8 times greater than the value of X, (t.e.esli N> 8). The value of X (the value of the victim) will not matter if it will help in the removal of insects or rescuing a drowning man. This will be expressed in the degree of love for a possible relative (recipient). Feelings such as adaptive behavioral traits, according to the theory of kin-selection should be formed in the selection process. When the apparent complexity, this method of determining the level of altruism distributed not only in human society, but also in various animal species. This method of determining the degree of kindness, a good degree of relationship of one individual to another. If an individual, as a recipient, not provided the minimum donation service, although for the recipient, this service would be, for example, more than 300 times more valuable than the cost of potential donors to provide this service, it is clear that the degree of love (the level of altruism) to this individual (the recipient) is lower than, for example to chetveroyurodnomu nephew (r = 1 / 256). And in any other, more serious situation if, for example life threatening individual, the attitude to it is the same. The value of N, which can count this individual as the recipient, will remain unchanged. Altruist able to recognize this dependence will increase their ability to recognize "altruism gene" and "selfish genes". The ability to share information can also improve the efficiency of recognition. Sheet 6 Thus, although selection for reciprocal altruism - a selection for a mutually beneficial adaptive features, but such selection would favor the true altruists, as the most profitable reciprocal partner, perceiving close and distant relatives, as the carrier-degree relatives, greater than that caused by a genetic factor relatedness r.
