ML trees and test statistics for model tests performed on the supermatrix dataset.

ML trees and test statistics for model tests performed on the supermatrix dataset. Models used are as in Figure 1. LRTs were performed between the model considered and the next-smallest nested model. Models with Mgene option G were tested against both G and G models. AIC is the difference in between a model and the best-fitting model. Partitioned models were also tested against their concatenated version (in brackets). Significant P-values (0.001) are indicated by a star. Trees A and B are shown in Supplementary Figure S4.
