What is one of the major lines of evidence indicating that there were multiple transitions to land in the Lophotrochozoa?

Like plants, all terrestrial protostomes descended from a single aquatic ancestor.

The outgroup of protostomes is aquatic. However, all terrestrial lophotrochozoans descended from the same aquatic ancestor.

Molecular phylogenies of the Ecdysozoa show multiple water-to-land transitions, so it is likely that it occurred in the Lophotrochozoa as well.

The outgroup to protostomes is aquatic, and the annelid and mollusc lineages have both aquatic and terrestrial members.
