Figure 6

Most parsimonious reconstructions for the evolution of anchor cell-vulval precursor cell interactions. Depending on the relationships of the taxa, the association of the anchor cell specifically with P6.p could have been apomorphic (derived, one possibility in tree c) or ancestral (as in trees a and b). Because the relationships are not yet well known (although Fig. 4 suggests tree c), any of these scenarios is possible.
