Unlike the charts in this exhibition that illustrate a single species or detail a particular anatomical structure, this one summarizes a broad topic: evolution in the animal world. Despite the complexity of the subject, the chart is clearly organized. Related organisms are connected by colored lines, missing information is indicated by question marks, extinct species are illustrated in black-and-white, and a scalloped blue line marks the division between water- and land-dwellers.
