Evolutionary trajectories of Auguritidae and Pinacitidae in the morphological space
defined by the three characters involved in the case of parallel evolution. A, Statistical evaluation of the parallel evolution by means of the trajectory approach
of [123]. Plot of the first and second principal components estimated from the correlation
matrix for auguritids and pinacitids based on the three standardized characters UWI,
Dmx, and NLb. Statistical evaluation of the parallel evolution is indicated with and
without the auguritid outlier taxon Weyeroceras angustus (dashed line). Parameters with more than minimal support are in bold. There are no
significant differences in magnitude and direction of the trajectories, but they are
different in shape. B, Statistical evaluation of the parallel evolution by means of
the regression approach of [121]. The phylogenetic trajectory of each lineage is fitted by a linear total least square
regression. The statistical evaluation is indicated without the auguritid outlier
taxon. The p-value of the test (p = 0.0197) is low, but the hypothesis of parallel trajectories could not be rejected
by the permutation test.
