Figure 2. Deuterostomic development of the brachiopod, L. anatina, and its close relationship to molluscs. (a) Adult (shell length ~4–5 cm). (b–i) Embryogenesis: egg (b), embryos at 4-cell (c), 16-cell (d), 32-cell (e) and 128-cell stages (f), blastula (g), late gastrula (h) and 2-pair cirri larva (i). Scale bar, 50 μm. bp, blastopore; cr, cirri; ct, chaeta; gt, gut; ml, mantle lobe; mo, mouth; pd, pedicle; sh, shell; st, stone. (j) Phylogenetic position of Lingula among lophotrochozoans (orange box; molluscs are blue; annelids are green). The tree was constructed using the maximum likelihood method with 150 one-to-one orthologues (46,845 amino-acid positions) with LG+Γ4 model. Circles at all nodes indicate 100% bootstrap support.
