Simulation of an agent-based model of multi-level group selection under a controlled environment.
This simulation shows two outcomes:
1. Without group selection pressures (without war/without group conflict),
Non-Altruistic populations will increase over time.
2. Under the pressures of group selection (with war/with groups conflict),
The altruistic population will increase over time.
I'd like you to please read the term paper for a more technical view and outcome.
