Proponents of the standard evolutionary biology paradigm explain human “altruism” in terms of either nepotism or strict reciprocity. On that basis our underlying nature is reduced to a function of inclusive fitness: human nature has to be totally selfish or nepotistic. Proposed here are three possible paths to giving costly aid to nonrelatives, paths that are controversial because they involve assumed pleiotropic effects or group selection. One path is pleiotropic subsidies that help to extend… 
Group Selection and the Limits to Altruism
The level of human altruism that could exist if group selection were an engine of human evolution is examined, and altruistic behavior that would lead to faster growth is called ‘efficient altruism’.

It is suggested that four evolutionary developments combined to provide a genetic basis for psychological altruism: the evolution in mammals of parental nurturance, the ability to see others as sentient, intentional agents, cognitive capacities that make it possible to generalize tender, empathic feelings and, thereby, altruism beyond offspring.
Evolutionary accounts of belief in supernatural punishment: a critical review
This work distinguishes two divergent and often conflated approaches to supernatural punishment theory which hypothesize the adaptive character of such beliefs arise from the fact that they increase cooperation or decrease the cost of incurring punishment for norm violations.
Identity, Kinship, and the Evolution of Cooperation
It is proposed that the evolution of human cooperative behavior required a capacity for self-sustained, self-referential thought manifested as an integrated worldview, including a sense of identity and point of view, and the cultural formation of kinship-based social organizational systems within which social identities can be established and transmitted through enculturation.
Financial Altruism or Unilateral Resource Exchanges? Toward a Pure Sociology of Welfare*
Questions concerning the essential nature of altruism, the existence of an altruistic personality, and the genetic, biosocial, and social psychological bases of altruistic behavior have dominated

Current evidence supports the hypothesis that selection has favored a hunt-and-kill propensity in chimpanzees and humans, and that coalitional killing has a long history in the evolution of both species.
New Evolutionary Perspectives on Altruism: Multilevel-Selection and Costly-Signaling Theories
New perspectives offered by multilevel-selection theory and costly-signaling theory may help to shed light on some of the more problematic issues in the study of altruism.

Conflict and the evolution of social control.
With an interest in origins, it is proposed that conflict within the group can be taken as a natural focus for exploring the evolutionary development of human moral communities. Morality today


Impact of the Human Egalitarian Syndrome on Darwinian Selection Mechanics

During the authors' prehistoric foraging phase, a highly stable egalitarian syndrome arose that had profound effects on Darwinian selection mechanics and is reflected in an ambivalent human nature that exhibits substantial altruism in addition to selfishness and nepotism.
A mechanism for social selection and successful altruism.
A simple and robust mechanism, based on human docility and bounded rationality, is proposed that can account for the evolutionary success of genuinely altruistic behavior.
The Evolution of Reciprocal Altruism

A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. The model shows how selection can operate against the cheater (non-reciprocator) in the
The Evolution of Strong Reciprocity
Where genetically unrelated members of a group benefit from mutual adherence to a social norm, agents may obey the norm and punish its violators, even when this behavior cannot be justified in terms
The biology of moral systems
The author argues that the ultimate interests of humans are reproductive, and that the concept of morality has arisen within groups because of its contribution to unity in the context, ultimately, of success in intergroup competition.
The origins of virtue : human instincts and the evolution of cooperation
The Origins of Virtue shows that recent research in a number of fields has suggested a resolution of the apparent contradiction between self-interest and mutual aid, and re-examines the everyday assumptions upon which the authors base their actions towards others.
The evolution of social behavior
For several years the study of social behavior has been undergoing a revolution with far-reaching consequences for the social and biological sciences, partly due to growing acceptance of the evidence that the potency of natural selection is overwhelmingly concentrated at levels no higher than that of the individual.
On the Genetics of Altruism and the Counter-Hedonic Components in Human Culture1
Man is more similar to the social insects than to the wolf and chimpanzee in complex social coordination, division of labor, and self-sacrificial altruism, but is profoundly ambivalent in his social role.
