On the left is a diagram of a phylogenetic tree that displays the twelve different species used in the study and their relationships to one another as they have evolved through time. To the right of this tree are the 3D shapes of their arm skeletal pieces and joint types shown from two different perspectives: distal is shown on the left and proximal is shown on the right. The names of the joints are listed in grey and yellow boxes to the right of the shapes, with the grey representing the distal viewpoint and the yellow representing the proximal. The different species on the phylogenetic tree are highlighted in pink, yellow, and green depending on their lifestyle. Epizoic or living on another animal, are highlighted in pink. Endozoic or living within another animal are highlighted in yellow and epiphytic or growing on the surface of a plant are in green.
