Ancestral state reconstruction of log10 baculum complexity across Carnivora. Consensus phylogeny sourced from 10kTrees project (https://10ktrees.nunn-lab.org/index.html). Trait evolution was reconstructed using the ‘phytools' function ‘fastAnc' and plotted using ‘contMap'. Cool colours = low alpha shape complexity; hot colours = high alpha shape complexity. Dorsal surface of three-dimensional models faces outwards from the tree root, distal tips point in an anti-clockwise direction. Clockwise from top: Mustela lutreola, Pteronura brasiliensis, Ursus maritimus, Mungos mungos, Panthera leo, Felis silvestris, Speothus venaticus, Canis lupus, Mirounga leonina, Mellivora capensis, Eira barbara. Example species for three-dimensional surfaces were selected as being representative of their closely related taxa. (Online version in colour.)
