The Milestones of Evolution Poster showcases vertebrate species throughout the Paleozoic, Mesozoic, and Cenozoic eras. This poster provides a comprehensive overview of vertebrate evolution in accordance with the new cladistics system, which it introduces. The most important evolved characteristics are shown and explained as the "Milestones of Vertebrate Evolution." These provide the foundation for grouping similar animals together into "clades."
Along the left edge, the major milestones (physical developments) of vertebrate evolution are shown and described. The main design is an “Evolution Tree” superimposed over the geological time scale. It shows and identifies all of the major clades. The "tree" design shows how each branched off from earlier ones and other relationships. Each of the milestones is predominately marked on the tree as they are the basis for the most important clades. The beginning and end of each branch shows when they lived; the thickness of the branch indicates their relative abundance or scarcity during each geological period. 119 species are shown, all in the proper geological period. This makes it easy to see which animals lived at the same time.
