Understanding and predicting human cooperative behavior and beliefs dynamics remain a major challenge both from the scientific and practical perspectives. Because of the complexity and multiplicity of material, social and cognitive factors involved both empirical and theoretical work tend to focus only on some snippets of the puzzle. Recently, a mathematical theory has been proposed [...]

In primates and other mammals, male care for immatures is generally restricted to species that form enduring pair bonds or breed cooperatively.

Natural selection has favored the evolution of some forms of male [...]
