Figure 9. Wilson (1892) cleavage stages
Diagrams of cleavage stages of a polyclad worm (A and C), a mollusc (D) and annelid worms (B and E) from Wilson (1892). Wilson was impressed with the similarity in the formation of mesoderm by these different groups of organisms. The shaded cells are the precursors of mesoderm. Wilson interpreted studies of cell lineage as showing that development is mosaic.
