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:

Punishment and spite, the dark side of cooperation
TL;DR: Although punitive sentiments might be the psychological force behind punitive behaviours, spiteful motives might also play an important role and functionally spiteful acts might not be maladaptive; reckoning gains relative to others rather than in absolute terms can lead to hyper-competitiveness, which might be an important part of human cooperation, rather than just an ugly by-product.

Strong Reciprocity and the Roots of Human Morality
TL;DR: It is argued that ethical behavior was fitness-enhancing in the years marking the emergence of Homo sapiens because human groups with many altruists fared better than groups of selfish individuals, and the fitness losses sustained by altruists were more than compensated by the superior performance of the groups in which they congregated.

Bionomics of the Large Carpenter Bees of the Genus Xylocopa
TL;DR: The large carpenter bees of the genus Xylocopa include more than 730 species, which are grouped into 48 subgenera, and include some of the largest bees, often exceeding 3 cm in length.

Brain and cognitive evolution: forms of modularity and functions of mind.
David C. Geary,Kelly J. Huffman +1 more
TL;DR: The authors argue that 4 forms of modularity and 3 forms of neural and cognitive plasticity define the relation between genetic constraint and the influence of developmental experience, which leads to the ontogenetic emergence of functional modules in the domains of folk psychology, folk biology, and folk physics.

Parasites and the Advantage of Genetic Variability within Social Insect Colonies
TL;DR: Using the natural system, bumble bees, Bombus terrestris, and their trypanosome parasites, Crithidia bombi, it is found that hosts vary in susceptibility or parasites in infectiousness, and that parasite transmission in social groups correlates with genetic relatedness among hosts.

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.
