Figure 4From: The coevolution of cooperation and dispersal in social groups and its implications for the emergence of multicellularityLocally optimal associations between dispersal and exploitation strategy. The frequency of dispersal in cooperators (y) and cheaters (z) evolves, and the frequency of cooperators (n) and cheaters (1-n) evolves. Initial frequencies in numerical studies: y = z = n = 0.5. As for Figure 1 except caption a: k = 1.2, c = 0.1; caption b: k = 10, c = 0.1; caption c: k = 1.2, c = 0.3; caption d: k = 10, c = 0.3.Back to article page
