e0“Morphological convergence caused by lineages repeatedly traversing shared regions of morphospace appears commonplace in Radula, and means that many pairs of relatively unrelated species have similar lobule shapes”

Other claims from this paper (10)
- Observation Radula subgenera overlap in lobule shape space, so shape does not always reflect relationships.
- Observation Adams Q-mode analysis found significant evolutionary rate variation, with the fastest subgenus evolving 23 times faster than the slowest.
- Observation Volutoradula species were apparently over-dispersed through lobule morphospace.
- Observation Metaradula species were apparently over-dispersed through lobule morphospace.
- Observation A stochastic process could explain morphometric branch lengths and hypervolumes in other subgenera.
- Observation BAMM assigned the highest posterior probability to a single evolutionary rate.
- Observation Three independent entries into auriculate lobule morphospace occurred in Cladoradula and Radula.
- Association Convergent lobule shapes were associated with convergent ontogenies, bipinnate branching and robust primary stems.
- Mechanism Auriculate lobules were hypothesized to be a spandrel of structural requirements for light interception.
- Mechanism Lobules were speculated to facilitate radiation into microsites lacking or poor in fungal endophytes.
