Fig. 2 in The Wettstein tesseract: A tool for conceptualising species-rank decisions and illustrating speciation trajectories

Fig. 2. The Wettstein tesseract unfolded, with vertices representing binary-coded (statistically significant) genealogical, geographical, ecological, and morphological differences between two sister-taxa under study (left) and their taxonomical counterparts (right). Colours of vertices are just for clarity of the illustration and have no semantic implication.
