Extraordinary siblings: Mole rats, marmosets, and Radcliffe-Brown. [PDF]
According to the theory of kin selection, an organism that shows some level of altruism toward her kin - lowering her own fitness, raising that of a close genetic relative - may enjoy an evolutionary advantage.

Gut microbiota alterations in golden snub-nosed monkeys during food shortage and parturition-nursing periods [PDF]
Adopting unique survival strategies during spring food shortages and simultaneous parturition and nursing is crucial for golden snub-nosed monkeys. Social behaviors, such as altruism within one-male units (OMUs), are decisive for family health, but the ...

What, If Anything, Is Biological Altruism?
The study of biological altruism is a cornerstone of modern evolutionary biology. Associated with foundational issues about natural selection, it is often supposed that explaining altruism is key to understanding social behaviour more generally ...

Coevolution of cooperation, causal cognition and mindreading
The evolution of cooperation between unrelated individuals has long been a puzzle in evolutionary biology. Formal models show that reciprocal altruism is approximately as stable as kin-based altruism when cooperators can assort.
