A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. [] Key Result Specifically, friendship, dislike, moralistic aggression, gratitude, sympathy, trust, suspicion, trustworthiness, aspects of guilt, and some forms of dishonesty and hypocrisy can be explained as important adaptations to regulate the altruistic system. Each individual human is seen as possessing altruistic and cheating tendencies, the expression of which is sensitive to developmental…

Human altruism as a courtship display

It is suggested that altruism can be viewed as a courtship display designed as an honest advertisement of the capacity and the intention of the altruist to be a reliable mate.

Explaining human altruism

It is defended the claim that human altruistic dispositions evolved through cultural group selection and gene-culture coevolution and offered empirical evidence in support and it is argued that actual altruistic behavior often goes beyond the kind of behavior humans have evolved to display.

How Culture Induces Altruistic Behavior

Sociobiologists have explained altruistic behavior by way of kinship theory and reciprocity theory. Nevertheless, there appears to be a considerable amount of human altruistic behavior that cannot be

The Evolution of Morality and Religion: Cooperation, altruism, reciprocal altruism

The system controlling any behaviour develops in the individual as a consequence of interactions between the genotype and its environment and to consider how genes might influence behaviour and how a gene which does so might have spread in the population is of value.

Altruism as a Handicap: The Limitations of Kin Selection and Reciprocity

Trivers (1971) suggested an additional model "reciprocal altruism" (RA) to interpret altruistic adaptations among non-relatives, but data from several field studies have indicated that in many cases the act of the non-related altruist was not reciprocated.

C Costly Signaling Theory

The existence of altruism was something of an obstacle for early evolutionary theorists, since an organism that engaged in behavior that came at a great personal cost and seemed to solely benefit

The survival of the kindest: a theoretical review and empirical investigation of explanations to the evolution of human altruism

Charles Darwin was concerned that his entire theory of evolution by natural selection might be negated by a phenomenon prevalent in a variety of species including humans; namely altruism. If natural

The Evolution of Altruism via Social Addiction

It is argued below that the standard natural selection approach does not do an adequate job of explaining the origins of altruistic behavioural adaptations and instead explains how they might be stabilized or modified with respect to alternatives in a given environment.

Both measures show that three college groups all differentiate among friend, stranger, and antagonist, and YMCA college students are generally more positively oriented toward the other's welfare-friend, Stranger, or antagonist.


The manner in which the concept of reciprocity is implicated in functional theory is explored, enabling a reanalysis of the concepts of "survival" and "exploitation." The need to distinguish between

The Descent of Man, and Selection in relation to Sex

It is shown that secondary sexual characters are eminently variable, and that males vary more than females from the standard of the species, a standard determined by the young, by allied forms, and sometimes by the character of the male himself when his peculiar functions are only periodical, or when they have been artificially prevented.

Trust and suspicion

Whenever philosophers, poets, statesmen, or theologians have written about man's relationship to his fellow man, to nature, or to animals, the phenomena of trust and betrayal, faith and suspicion,

The Genetical Theory of Natural Selection

Although it is true that most text-books of genetics open with a chapter on biometry, closer inspection will reveal that this has little connexion with the body of the work, and that more often than not it is merely belated homage to a once fashionable study.
