Abstract We study the networking effects on the population divergence and the increased level of cooperation in the continuous snowdrift game (CSG). In the regular world, limited interaction inhibits the occurrence of evolutionary branching. The formation of clusters defends the intermediate-investors from
intruding by high- or low-investors. In a rewired network, the collective behaviour is related to the rewiring rules. A linear relationship I=a\σa +b between the average investment and the standard deviation of the degree distribution is found.
