Evolution in International Relations

Scholars of international relations (IR) and evolution pay little attention to each other's fields. However there is a need to examine evolution's impacts in IR. International actors such as nations are made up of people so evolved human nature has an impact on relations within and between states. Accordingly this pathbreaking Element will attempt to apply insights from evolutionary biology evolutionary psychology neuroscience and archaeogenetics to IR. Among such insights are the evolved role of emotions in decision-making intergroup competition as a driver of in-group cooperation and culture morality and language as group-binding mechanisms. Homo sapiens is a primate so comparison with the behaviours of other great apes reveals some commonalities in terms of group dynamics status and hierarchies as well as the enduring human capacity for both in-group cooperation and organised violence against other groups. These have an evolutionary basis that is relevant to IR theory and practice.
