Table 1. Values of the key parameters used during the simulations.

	Baseline values	Range explored
Group size (n)	20	5–30
Migration rate (m)	0.15	0.05–0.25
Probability of conflict (k)	0.20	0.05–0.30
Baseline fitness (w0)	0	0–5

According to⁵⁷, these values might properly reflect early human environments.
