Altruism Among Female Macaca Radiata: Explanations and Analysis of Patterns of Grooming and Coalition Formation
TLDR
Analysis of the observed patterns of two forms of putative altruism among adult female members of a group of captive bonnet macaques (Macaca radiata) indicates that both kinship and dominance rank influence the distribution and rate of these behaviors.Abstract:
Analysis of the observed patterns of two forms of putative altruism (grooming and coalition formation) among adult female members of a group of captive bonnet macaques (Macaca radiata) indicates that both kinship and dominance rank influence the distribution and rate of these behaviors. Females groom their adult relatives more often and more reciprocally than they groom unrelated females of similar ranks. In addition, females are more likely to support their relatives than nonrelatives and are likely to incur greater risks when they do so. Grooming and coalition formation do not occur exclusively among kin. Females primarily groom higher ranking females and support unrelated females against females lower ranking than themselves. Although females do not preferentially support unrelated females that groom or support them most, they do refrain from harassing lower ranking females that are currently grooming them or a female higher ranking than themselves. Thus, by grooming a higher ranking female a female reduces the probability that she will be harassed by other females. The relationship of these results to predictions derived from several different sociobiological hypotheses is discussed.read more

Social relationships among adult female baboons (papio cynocephalus) I. Variation in the strength of social bonds
TL;DR: Testing a number of predictions derived from kin selection theory about the strength of social bonds among adult female baboons suggests that social bonds play a vital role in females’ lives, and the ability to establish and maintain strong social bonds may have important fitness consequences for females.

TL;DR: For example, the authors found that individuals who were reluctant to share (i.e., showed a low rate of food distribution) had a higher probability of encountering aggression when they themselves approached food possessors.

TL;DR: Empirical evidence from phylogenetically controlled analyses is presented indicating that evolutionary increases in the size of the vocal repertoire among non-human primate species were associated with increases in both group size and time spent grooming.

The Evolution of Cooperation
TL;DR: In this paper, a model based on the concept of an evolutionarily stable strategy in the context of the Prisoner's Dilemma game was developed for cooperation in organisms, and the results of a computer tournament showed how cooperation based on reciprocity can get started in an asocial world, can thrive while interacting with a wide range of other strategies, and can resist invasion once fully established.

TL;DR: A genetical mathematical model is described which allows for interactions between relatives on one another's fitness and a quantity is found which incorporates the maximizing property of Darwinian fitness, named “inclusive fitness”.

The Evolution of Reciprocal Altruism
TL;DR: In this paper, a model is presented to account for the natural selection of what is termed reciprocally altruistic behavior, and the model shows how selection can operate against the cheater (non-reciprocator) in the system.
