Fig. 2From: Paleozoic diversification of terrestrial chitin-degrading bacterial lineagesChronogram depicting the phylogenetic relationships between chitinase homologs, and posterior age estimates obtained under the prior. This illustrates date distributions of key fungal and bacterial clades assuming a uniform distribution with uncorrelated gamma multipliers. On the bottom of the figure, the date distributions of key nodes are interwoven with events in the evolution of the major sources of environmental chitin: fungi and marine and terrestrial arthropodsBack to article page
