Before I get to my questions I want to apologise for mistakes and errors I might have done writing this since English is not my first language.

Currently, I am preparing for my finals ( which would be somewhat between a bachelor and a master in Political Science. One of the fields I need to know about is the field of International Relations (IR) and their respective theories. Recently, I came across an article that mentioned the Theory of Evolution on a international scale, meaning that one nation's international policy and politics is determined by "survival of the fittest".

Does anyone know about some theories that combine IR and ToE? I would be grateful for everything, from articles to monographies.

If not, it would be great if you left a comment so I can get inspired and maybe conduct some research on my own.

Thank you very much
