Other claims from this paper (10)
- Observation Radula subgenera overlap in lobule shape space, so shape does not always reflect relationships.
- Observation Convergent lobule shapes are commonplace among relatively unrelated Radula species.
- 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.
