TLDR
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”.About:

Surveying the Moral Landscape Moral Motives and Group-Based Moralities
TL;DR: This model challenges the conclusions of Haidt and colleagues that only conservatives (not liberals) are group oriented and embrace a binding morality and explores the implications of this new model for politics in particular and for the self-regulation versus social regulation of morality more generally.

Flexible helper structure as an ecological adaptation in the pied kingfisher (Ceryle rudis rudis L.)
TL;DR: It is argued that-originating from a skewed sex ratio and breeding in colonies-this adaptation evolved through the combined effects of individual and kin selection.
Journal ArticleDOI
Evolution of colony characteristics in social insects. i. sex allocation
TL;DR: The inclusive-fitness model elaborated in this article can be applied to derive the expected allocation patterns of social insects, both as a function of the type of colony and of the amount of resources the colony can use in sexual production.

Spatial self-organization favors heterotypic cooperation over cheating.
TL;DR: Self-organization, driven by asymmetric fitness effects of cooperators and cheaters on partners during cell growth into open space, achieves assortment.

Mothers matter! Maternal support, dominance status and mating success in male bonobos (Pan paniscus)
TL;DR: Mating success determinants in male bonobos are evaluated using data from nine male individuals from a wild population and results reveal a steep, linear male dominance hierarchy and a positive correlation between dominance status and mating success.

Animal dispersion in relation to social behaviour
TL;DR: Wynne-Edwards has written this interesting and important book as a sequel to his earlier (1962) Animal Dispersion in Relation to Social Behaviour, and reviewing it has proven to be a valuable task for one who normally is only at the periphery of the group selection controversy.
