Fig. 11From: An integrative systematic framework helps to reconstruct skeletal evolution of glass sponges (Porifera, Hexactinellida)Simplified phylogeny of Hexactinellida (after Figs. 8, 9 and 10) showing tentative scenario of the evolution of selected characters. Blue branches represent lyssacine taxa, brown branches represent dictyonal taxa. Note that the reconstruction of some characters is sensitive to alternative topologies and/or ancestral state reconstruction model (see text for details).
