Community complexity drives patterns of natural selection on a chemical defense of Brassica nigra.
TL;DR: The results show that the selective value of ecologically important traits depends on the complicated web of interactions present in diverse natural communities and that fluctuations in community composition may maintain genetic variation in such traits.
Diminishing returns in social evolution: the not-so-tragic commons
TL;DR: This paper examined how varying the fitness returns from reproductive competition or cooperation affects the negative impact of competition on a social group and showed that diminishing returns are common in many systems, including social vertebrates, microbes, social insects and mutualisms among species.

Voting with your feet: Payoff biased migration and the evolution of group beneficial behavior.
Robert Boyd,Peter J. Richerson +1 more
TL;DR: This model suggests that long run outcomes depend on the relative strength of migration and local adaptation and when local adaption is strong enough to preserve cultural variation among groups, cultural variants that make societies attractive always predominate, but never drive alternative variants to extinction.

Natural selection. IV. The Price equation.
TL;DR: The Price equation as discussed by the authors partitions total evolutionary change into two components: the first component provides an abstract expression of natural selection and the second component subsumes all other evolutionary processes, including changes during transmission.

Contingent movement and cooperation evolve under generalized reciprocity
Ian M. Hamilton,Michael Taborsky +1 more
TL;DR: It is shown that cooperation may be evolutionarily stable if decisions taken to cooperate and to change group membership are both dependent on anonymous social experience (generalized reciprocity), and that mechanisms of assortment within populations are often behavioural decisions and should not be considered independently of the evolution of cooperation.
