The ways in which natural selection can allow the proliferation of cooperative behavior have long been seen as a central problem in evolutionary biology. Most of the literature has focused on interactions between pairs of individuals and on linear public goods games. This emphasis has led to the conclusion that even modest levels of migration would pose a serious problem to the spread of altruism through population viscosity in group structured populations. Here we challenge this conclusion, by…

Invasion, polymorphic equilibria and fixation of a mutant social allele in group structured populations
TLDR
Social evolution in a large class of group structured populations, with arbitrary multi-individual interactions among group members and random migration among groups, is studied, showing that three regimes occur, depending on the migration rate among groups.
The evolution of cooperation under local regulation and non-additive gene action: building on Hamilton’s ideas
TLDR
This work studies evolution of cooperation in a population structured in a large number of groups of variable size, connected by random migration at rate m, and obtains the following contrasting conclusions.
A simple rule for the evolution of contingent cooperation in large groups
  • R. Schonmann, R. Boyd
  • Biology
    Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2016
TLDR
A simple formula is derived that gives the relatedness necessary for contingent cooperation in n-person iterated games to increase when rare and suggests that modest levels of relatedness are sufficient for invasion by strategies that make cooperation contingent on previous cooperation by a small fraction of group members.
How to make a kin selection model when marginal fitness is non-linear?
We observe that the Taylor-Frank method for making kin selection models when fitness w is a nonlinear function of a continuous actor’s phenotype y and the average phenotype z in its social
Human large-scale cooperation as a product of competition between cultural groups
TLDR
It is shown that readiness to cooperate between individuals from different groups corresponds to the degree of cultural similarity between those groups, consistent with the theory of Cultural Group Selection as an explanation for the rise of human large-scale cooperation.
Value homophily benefits cooperation but motivates employing incorrect social information.
The evolution of extreme cooperation via shared dysphoric experiences
TLDR
A mathematical model shows how conditioning cooperation on previous shared experience can allow individually costly pro-group behavior to evolve, and empirical results show that sharing painful experiences produces “identity fusion” – a visceral sense of oneness – which in turn can motivate self-sacrifice, including willingness to fight and die for the group.
Modelos matemáticos para evolução social: de cooperação à diversidade linguística
TLDR
The Two-Level Fisher-Wright framework is applied to the problem of the evolution of altruism in populations of hunter-gatherers, considering a situation in which group conflict drives selection.
Collective action and the collaborative brain

TLDR
This work theoretically study the evolution of social-cognitive competencies as driven by selection emerging from the need to produce public goods in games against nature or in direct competition with other groups.

Conditions for the evolution of altruism under Darwinian selection.
Demography, altruism, and the benefits of budding
TLDR
This work model the effects of individual dispersal, budding disperseal, soft selection and hard selection to examine the conditions under which altruism is favoured and examines how these various demographic details feed into relatedness and scale of competition parameters that can be included into Hamilton's rule.
The Effect of Stochastic Variation on Kin Selection in a Budding-Viscous Population
TLDR
Computer simulations confirm that in populations with a viscous, permanent group structure, an altruist allele always fails in the absence of stochastic variation but follows Hamilton's rule if realistic levels of random variation are maintained.
Two-level Fisher-Wright framework with selection and migration: An approach to studying evolution in group structured populations
TLDR
The early stages of the evolution, during which the number of altruists is small compared to the size of the population, are analyzed, and it is shown that during this stage the evolution is well described by a multitype branching process.

TLDR
The group selection analogue of Hamilton's inequality, c/b less than r, where r is the coefficient of relationship, is obtained and the effect of isolation is enhanced if migration is mainly between adjacent groups and if group splitting is along family lines, as data on population structure of primates seem to indicate.
The evolution of cooperation and altruism – a general framework and a classification of models
TLDR
A synthetic conceptual framework is developed that delineates the conditions necessary for the evolution of altruism and cooperation and classifies them into four general categories.

  • L. Avilés
  • Biology
    Proceedings of the National Academy of Sciences of the United States of America
  • 2002
TLDR
It is shown that freeloaders, whose presence is reflected in the development of linkage disequilibrium between grouping and cooperation, increase in frequency when rare, but are selected against when common due to the reduced productivity of the groups they overburden with their presence.
A CONDITION FOR GROUP SELECTION TO PREVAIL OVER COUNTERACTING INDIVIDUAL SELECTION

  • 1982
TLDR
A haploid one-locus two-allele no mutation model is analyzed, where genetic differentiation of groups is generated in most part by random genetic drift and reduced partly by migration, and whether group selection can prevail over individual selection to bring about the evolution of an altruistic trait is addressed.

TLDR
It is shown that with an inclusive fitness model, that the same result holds in a patchstructured population, thus opposing the evolution of local altruistic behaviour.
