Fig. 4 — Divergence times and distribution of different types of orthologues in representative species. (a)Estimated divergence times of representative species based on the phylogenomic analysis. The blue bars in the ancestral nodes indicate the 95% confidence intervals of the estimated divergence time (MYA, million years). Different background colours represent the corresponding geological age. (b) Distribution of different types of orthologues in the selected representative species.
