Dear morphometricians, I have the following problem:
I have performed a PCA of shape (relative warps analysis) on a set of mouse mandibles from animals of different geographic origins. Now in a plot of PC1 vs PC2, I can "see" that PC1 sorts specimens into broadly overlapping clusters corresponding to the respective origins of the mice, while PC2 (and the other PCs) do not. The problem is now that the overlaps of the "population" clusters are rather broad so the question is how different they actually are. Also, I have several "populations", so it looks like a continuum of overlapping clouds. Could you recommend a means to quantify and/or somehow test the actual differences between "populations" along PC1?
