Variable plots illustrating the correlation of pedal and manual digit length IV with other imprint measures

A-B, manus length vs. pedal digit length IV. C-D, pes length vs. pedal digit length IV. E-F, arithmetic mean of all other toe lengths vs. pedal digit length IV. G-H, arithmetic mean of all other toe lengths vs. manual digit length IV. Plots on the right side represent ln-ln plots of the same variable pairs depicted on the left side.

PCA results based on logarithmized length ratios

The variable combinations and samples of the six depicted PCA results correspond to diagrams depicted in the manuscript: A, Biplot (PC1 vs. 2) for a PCA of four logarithmized manual toe ratios, corresponds to Fig. 12B. B, PCA result for the same data as in A but based on the correlation matrix. C, Biplot (PC1 vs. 2) for a PCA of four logarithmized pedal toe ratios, corresponds to Fig. 12A. D, PCA result for the same data as in C but based on the correlation matrix. E, Biplot (PC1 vs. 2) for a PCA of two logarithmizedlength ratios and four angle measures, corresponds to Fig. 13A. F, Biplot (PC1 vs. 2) for a PCA of two logarithmized length ratios and four angle measures, corresponds to Fig. 14C.
