From: Paleozoic diversification of terrestrial chitin-degrading bacterial lineages
Posterior date distributions for aquatic (blue) and terrestrial (brown) bacterial chitinases. Posterior date distributions correspond to the uniform prior and uncorrelated gamma relaxed clock model with calibration 4 (Model 6). Aquatic nodes represent ancestors of groups within Vibrionales (165), Gammaproteobacteria (214), and Bacteroidetes (174). Terrestrial nodes represent ancestors of groups within Betaproteobacteria (149), Deinococcus (212), Actinobacteria (215) and Firmicutes (181)
