How may patterns of behavior change over an organism's lifetime? The answer is that they evolve (behavioral evolution) as species evolve over generations (biological evolution). In biological evolution, under certain conditions, groups of cooperative organisms would be selected over groups of non-cooperative organisms, even when cooperation imposes a cost to individuals. Analogously, in behavioral evolution, patterns of acts may be selected even when each individual act in the pattern is costly… Expand

A multi-armed bandit algorithm speeds up the evolution of cooperation
It is shown that a multi-armed bandit (MAB) model, a classic problem in decision sciences, is naturally employed by individuals to opt for the best choice most of the time, accelerating the evolution of the altruistic behavior and solving the abovementioned problems. Expand
An evolutionary model of reinforcer value
A formal model of reinforcer value is presented that is consistent with existing work on the nature of reinforcement and provides an explicit link between behavioral psychology and evolutionary biology and it is demonstrated how the established link between reinforcement value and evolutionary fitness can be used to derive new hypotheses.

Dugnad: A Fact and a Narrative of Norwegian Prosocial Behavior.
It is proposed that learning prosocial and cooperative behavior, which is central in a particular Norwegian cultural practice, dugnad, plays a role in the country's success story. Expand
Reciprocity With Unequal Payoffs: Cooperative and Uncooperative Interactions Affect Disadvantageous Inequity Aversion
Results confirmed the first hypothesis that uncooperative interactions would produce aversion to disadvantageous inequity and indicated that information about monetary outcomes did not affect aversion to inequity, contradicting the second hypothesis. Expand

En effet, un cadre theorique nomme "Vortex d'extinction du aux males diploides" predit une correlation negative entre isolations des populations, diversite genetique et production of males diPLoides pouvant amener a l' Extinction de populations d'Hymenopteres. Expand
Clinical psychology is an applied evolutionary science.
The time seems ripe to view clinical psychology as an applied evolutionary science, especially as it focuses more on processes of change. Expand


Can Group-Functional Behaviors Evolve by Cultural Group Selection?: An Empirical Test
Functionalists believe that social and cultural variation results from adaptation at the group level. Such explanations are controversial for two reasons: (i) Extensive analysis of mathematicalExpand
The genetical evolution of social behaviour. I.

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”. Expand
The evolution of altruistic punishment
It is shown that an important asymmetry between altruistic cooperation and altruistic punishment allows altruistic punished to evolve in populations engaged in one-time, anonymous interactions, and this process allows both altruism punishment and altruism cooperation to be maintained even when groups are large.

The cultural evolution of emergent group-level traits

  • Behavioral and Brain Sciences
  • 2014
The emergence and evolution of group-level traits and the implications for the theory of cultural evolution are discussed, including ramifications for the evolution of human cooperation, technology, and cultural institutions, and for the equivalency of multilevel selection and inclusive fitness approaches. Expand
Five Rules for the Evolution of Cooperation
Five mechanisms for the evolution of cooperation are discussed: kin selection, direct reciprocity, indirect reciprocities, network reciprocation, group selection, and group selection. Expand
Evolution "for the Good of the Group The process known as group selection was once accepted unthinkingly, then was widely discredited; it's time for a more discriminating assessment
Is evolution a team sport, or is the contest f r survival played out strictly between individuals? There's no question that natural selection acts on individual organisms: Those with favorable traitsExpand
The nature of human altruism
Current gene-based evolutionary theories cannot explain important patterns of human altruism, pointing towards the importance of both theories of cultural evolution as well as gene–culture co-evolution. Expand
The foundress’s dilemma: group selection for cooperation among queens of the harvester ant, Pogonomyrmex californicus
It is shown that group selection can explain the evolution of cooperative nest founding in the harvester ant Pogonomyrmex californicus, and it is found that aggressive individuals had a survival advantage within their nest, but foundress groups with such non-cooperators died out more often than those with only cooperative members. Expand
Altruism among relatives and non-relatives
The present experiment determined the amount of their own monetary reward undergraduates were willing to forgo in order to give $75 to other people at various social distances and found that genetic relationship and altruism varied inversely with social distance, implying that altruism is determined by factors in addition to social distance.

Selection by consequences.
Natural selection has now made its case, but similar delays in recognizing the role of selection in the other fields could deprive us of valuable help in solving the problems which confront us. Expand
