Developmental Changes in Morphology of the Middle and Posterior External Cranial Base in Modern Homo sapiens

Figure 3

Plot of the first four principal components of the basicranial landmark configuration that were significantly correlated with developmental age and centroid size: (a) PC1 versus PC2 (representing 14.83% and 9.31% of the variance, resp.); (b) PC3 versus PC4 (7.57% and 6.53% variance, resp.). Each quadrant of the plot contains a wireframe indicating the morphology typical for the specimens in that quadrant.
