Supplementary Information
Supplementary Methods and Discussion.
Supplementary Table 1
Predicted values with 95% CIs estimated for n = 500 randomized sets that resulted from reshuffling the observed values of the B vitamin thiamine across the species with known value of the vitamin. The predictions were conducted following the approach of Cantwell-Jones et al.1.
Supplementary Table 2
Predicted values with 95% CIs estimated for n = 500 randomized sets that resulted from reshuffling the observed values of the B vitamin riboflavin across the species with known value of the vitamin. The predictions were conducted following the approach of Cantwell-Jones et al.1.
Supplementary Table 3
Predicted values with 95% CIs estimated for n = 500 randomized sets that resulted from reshuffling the observed values of the B vitamin niacin across the species with known value of the vitamin. The predictions were conducted following the approach of Cantwell-Jones et al.1.
Supplementary Table 4
Predicted values with 95% CIs estimated for n = 500 randomized sets that resulted from reshuffling the observed values of the B vitamin pantothenic acid across the species with known value of the vitamin. The predictions were conducted following the approach of Cantwell-Jones et al.1.
Supplementary Table 5
Predicted values with 95% CIs estimated for n = 500 randomized sets that resulted from reshuffling the observed values of the B vitamin folate across the species with known value of the vitamin. The predictions were conducted following the approach of Cantwell-Jones et al.1.
Supplementary Table 6
Exact and adjusted P values (Bonferroni correction) of two-sample Wilcoxon tests between P2sim and P2sim-null scores (one test for each B vitamin and candidate species, totalling 1,616 tests).
Supplementary Table 7
P2sim and P2sim-null scores obtained for each B vitamin and candidate species.
Supplementary Software 1
R script for reshuffling the observed values of the B vitamins analysed in the study.
Supplementary Software 2
R script for conducting predictions with 95% CIs for the randomized sets following the approach of Cantwell-Jones et al.1.
Supplementary Software 4
R script for applying the method described in Molina-Venegas et al.4 to evaluate the expected accuracy of predictions conducted under a white-noise model of evolution.
