Fig. 2From: Fin modules: an evolutionary perspective on appendage disparity in basal vertebratesDistribution of fin conditions on the supertree of fishes showing the interrelationships among extant and extinct orders of fishes. Some non-ordinal ranked taxa that were included in the supertree analysis have been pruned for simplification. Colored squares above terminal branches represent sampled fin character states for each order/subgroupBack to article page
