Figure 4

PLS regression between the humerus shaft cortical topography block and (a) life history traits (body mass, age, bone volume) and (b) muscle ACSA blocks. Wild-caught wild boars are visualized in the filled green circles and captive-reared wild boars in the open blue circles. Black lines represent the PLS regression line. Shaft cortical topography deformations are visualized with two extreme cortical thickness maps where muscle attachment sites are encircled as visual cues. Singular vectors are shown using a barplot for life history (a) muscle ACSA and (b) blocks.
