Table 1. Mitochondrial substitution rates of Castor differ significantly from those of other rodents.
Median rate at tips | Median rates averaged | |
Castor vs. rest of mouse-clade | U = 36, p-value = 0.004998 ** | U = 42, p-value = 0.002591 ** |
Castor vs. rest of rodents | U = 58, p-value = 0.01375 * | U = 60, p-value = 0.007005 * |
Castor vs. rest of glires | U = 62, p-value = 0.1075 | U = 60, p-value = 0.1457 |
Results of Mann-Whitney U-tests testing the null hypothesis that substitution rates for Castor are identical to the rates of other rodents (Wilcoxon rank sum test with continuity correction as implemented in R).
*: significant, <0.05;
**: highly significant, <0.005.
