Fig. 4. ILS analyses.

Fig. 4

a Estimated theta value for each internal branch of the 14 species. b Estimated theta value for each internal branch of the 41 species. Warmer colors indicate higher theta and thus higher ILS level. Terminal branches are colored gray due to lack of data to infer theta. cf represent the correlation analyses of topology frequency of each quartet species combination in the different dataset: the simulation without ILS by Phybase and empirical observation (c), the simulation with ILS by Phybase and empirical observation (d), the simulation with ILS by DendroPy and empirical observation (e), the simulation with ILS by Phybase and DendroPy (f). The “lm()” function in R was used to perform all the correlation analyses, and the p values were both less than 0.01. Source data are provided as a Source Data file.
