Figure 1

A cladogram showing the phylogenetic relationship of phyla and subphyla in Deuterostoma and the remote relationship of the protostoma with the phylum Mollusca (dashed lines). The clades denoted with ‘*’ are the animal groups from which egg coat ZP proteins have been previously identified. The clades denoted with ‘+’ are the subphyla investigated in this study. Figure modified from Bourlat et al., 2006 [28].
