Figure 2From: Phenotypic integration of brain size and head morphology in Lake Tanganyika CichlidsAnalysis of modularity: graph shows a histogram of the RV coefficients between 279 random partitions of the head of Lake Tanganyika cichlids. The value of the RV coefficient between our hypothetical modules (pre and post-orbital modules, RV coefficient = 0.70) is indicated with an arrow.Back to article page
