Dataset and script to: Morphometric variance, evolutionary constraints and their change through time in Late Devonian Palmatolepis conodonts

Sabrina Renaud, Catherine Girard & Anne-Béatrice Dufour
Phenotypic variation is the raw material of evolution. Standing variation can facilitate response to selection along “lines of least evolutionary resistance”, but selection itself might alter the structure of the variance. Shape was quantified using 2D geometric morphometrics in Palmatolepis conodonts through the Late Devonian period. Patterns of variance were characterized along the record by the variance-covariance matrix (P-matrix) and its first axis (Pmax). The Late Frasnian was marked by environmental oscillations culminating with the...
