barely significantp = 0.057
Divergence times Tests of the hypothesis of a strict, global molecular clock using likelihood ratio tests (Additional file 1 , Table S5) either rejected the clock at p < 0.05 but at barely significant p-values (PAUP clock analyses, p-values ranging from 0.021 to 0.049), or failed to reject the clock (PAML based ML analysis, p = 0.057).
