Fig. 4. Wilcoxan Signed Ranks Randomization for Jaccard Distances. Selection of 38 symbolic and 96 functional traits was randomized 10,000 times, and the resulting Wilcoxan Signed Ranks test statistic calculated for Jaccard Distances. The actual test statistic value of -5.8734 was exceeded only 56 times in 10,000 (P = 0.0056), showing that the evolution of symbolic traits is significantly faster than that of functional traits.
