Parochialism in a bird species: playbacks of distress calls induce hierarchical patterns of helping, the bird being more prone to cooperate with close members of their group. Remarkably, this pattern is independent of kinship.

I read a really interesting #anthropology paper Jones (2000) and worked through a group #nepotism #model it describes,
which combines #GameTheory and #KinSelection, to explain key features of #cooperation within culturally-defined #kin groups.

The #evolution of #cooperation in still a major topic in behavioural #ecology. Here is a nice experimental and theoretical study in #meerkat showing that indiscriminate #altruism possibly evolved when kin discrimination is prone to error, mean #relatedness among social partners is high, and the relative benefits of helping are large. #Science #kinselection
