Complementary Variety: When Can Cooperation in Uncertain Environments Outperform Competitive Selection?

Figure 2

Illustration of Kullback-Leibler relative entropy as a measure of strength of evolutionary selection. The left hand side illustrates a case with less variance in type fitness, less population change through selection, and smaller divergence between (0.5; 0.5) and (0.4; 0.6). The right-hand side illustrates the case with larger variance in type fitness, more population change through selection, and larger divergence between (0.5; 0.5) and (0.2; 0.8).
