The rise and fall of cooperation in populations with multiple groups

作者：

Highlights：

• A group-level selection dynamic induced by the implementation of an individual-level selection is proposed.

• The existence of an independent cooperator group is beneficial to the rise of cooperation in the population with multiple groups.

• Mutation and migration will inhibit the prevalence of cooperation by destroying the independence and purity of cooperator groups.

• A special kind of multi-person migration, group division, will inhibit the anti-cooperation effect of the mutation.
