From: The implications of thumb movements for Neanderthal and modern human manipulation
2B-PLS of shape covariation between the proximal joint of Mc1 and all joints of the trapezium across taxa. (A) 1st PLS axis; (B) 2nd PLS axis; (C) 3rd PLS axis. Neanderthals (green), early modern humans (black) and modern humans (red). The figures on the right represent the shapes associated with each minimum and maximum of the shape covariation axes (in blue and purple, respectively) in different anatomical views (the full bone of a random H. sapiens individual is depicted with each surface to aid interpretation). All shapes are scaled to approximately the same length. A anterior, P posterior, D distal, Px proximal, R radial, U ulnar.
