Visualizations in geometric morphometrics: how to
read and how to make graphs showing shape changes

Abstract
An important aspect of geometric morphometrics,
since its beginnings, was the visualization of
shape changes. A range of methods has been
developed with advances in statistical shape
analysis and new possibilities in computer
graphics. Most approaches are based either on
relative shifts of landmark positions in starting
and target shapes after superimposition or on
D’Arcy Thompson’s idea of transformation grids.
Both approaches are in wide use in current
morphometrics, and both have their distinctive
advantages and shortcomings. This paper discusses
the assumptions and some caveats of both
approaches. The paper also offers some
recommendations for authors of geometric morphometric studies.
