(2004) tested whether the pattern of dispersal, and hence relatedness mattered with an experimental evolution approach. They initiated populations of the bacteria Pseudomonas aeruginosa with a mixture of the cooperator and the free rider, and then maintained them under conditions that would lead to either a high or low average relatedness. They did this by splitting the population into subpopulations, and then initiating each subpopulation, in each round of growth, with either a single bacterial clone (relatively high relatedness) or two bacterial clones (lower relatedness). What did their results in the figure show and is it consistent with kin selection theory? O The wild-type cooperator did much better when relatedness was higher, yes The wild-type cooperator did much better when relatedness was higher, no O The wild-type cooperator did much better when relatedness was
