Extended Data Fig. 2: A power analysis confirmed the validity of Ornstein Uhlenbeck models for three key traits.

We used a Monte Carlo-based method to investigate if our phylogeny provides support for the use of the Ornstein Uhlenbeck model. This returns the distribution of likelihood ratios under each model for (a) \({x}_{\bar{{\rm{C}}}{\rm{G}}}\), (b) maximum static margin, and (c) minimum static margin. Comparing the likelihood ratio distributions produced under both a Brownian motion (BM) model (grey) and Ornstein Uhlenbeck (OU) model (yellow) to the observed likelihood ratio (dashed black line) revealed that the Ornstein Uhlenbeck model was a better fit for our three key traits (see Methods).
