Figure 3 in Shell features and anatomy of the springsnail genus Radomaniola (Caenogastropoda: Hydrobiidae) show a different pace and mode of evolution over five million years
Figure 3. Rate, correlation and mode of evolution of 40 traits along the Radomaniola phylogeny. A, time-calibrated phylogeny and trait distribution. Traits were scaled between 0.01 and 1 to display their variation among taxa. B, diagonal showing the Brownian motion rate of trait evolution and off-diagonals the pairwise evolutionary correlation. Modularity is suggested by a higher correlation within a functional organ (black square) than between two groups. Integration is indicated by a high or low within-group correlation. C, barplots showing, for each group of traits, the support [corrected Akaike information criterion (AICc) weight] for the modes of trait evolution.
