The Utility of Geometric Morphometrics to Elucidate Pathways of Cichlid Fish Evolution
Figure 2
Illustration of the Procrustes superimposition of the (a) original configuration (raw coordinates). (b) First, the centroid of each configuration is translated to the origin. (c) After that, configurations are scaled to a common unit size and (d) optimally rotated to minimize the squared differences between corresponding landmarks.
