Maximum clade probability tree displayed as a chronogram from the BEAST analysis of the GS amino acid sequence alignment. All lineages evolved according to a relaxed molecular clock and WAG + Inv. + Gamma model. Node bars indicate the width of the 95% highest posterior density with minimum and maximum values in parentheses. Bold numbers near the nodes indicate node ages. Major lineages are depicted as collapsed triangles. Nodes for which fossil dates were used are marked as A = Acsomycota, 400MYA, B = Bilateria 550MYA and C = Streptophytes 475 MYA. P = Paleozoic; M = Mesozoic; C = Cenozoic; Camb. = Cambrian.
