Extended Data Fig. 7. Heterogeneity of habitat transition rates within clades.

Posterior probability distributions of the global habitat evolution rates of selected eukaryotic classes. In purple, are the global transition rates of three major eukaryotic lineages (Cercozoans, Ciliates, Gyristans) as shown in Fig. 2, and in green, are the global transition rates for selected clades within these lineages. From this analysis, we can see that Thecofilosea+Imbricatea tend to transition across the salt barrier faster than Cercozoans on the whole. Spirotrich ciliates have higher transition rates than ciliates on average, and chrysophtes (golden algae) and diatoms seem to have the highest transition rates across protists.
