  • Permulation P-values represent the proportion of 100,000 permulations that produced a stronger correlation with the change in carnivory score than the observed value for each gene. Multiple hypothesis testing corrections were performed by generating Q-values using Storey's correction method (Storey et al. 2020) (FDR = 0.05). A negative correlation (Rho) signifies the following pattern: the greater the decrease in carnivory, the higher the rate of evolution of the gene.

  • aAfter generating 100,000 null statistics, none produced a stronger correlation with diet than the observed values for SLC13A2 and SLC14A2. However, if the P-values are adjusted to the smallest observed nonzero P-value (1.00 × 10−5), they would produce a significant empirical Q-value (FDR = 0.05).
