Milestones of Vertebrate Evolution Chart
Introduces the Cladistics System

Designed as an Evolution Tree, this stylized cladogram uses the new cladistics system to group similar animals into clades. The tree design shows how each branched off from earlier ones and other relationships. Noted as Milestones of Vertebrate Evolution, the most important evolved characteristics are shown and explained. Each of the milestones is predominately marked on the tree as they are the basis for the most important clades. This Evolution Tree is superimposed over a geological time chart with the branches illustrating how milestones resulted in new groups of animals and the position of the branches shows how animals are related. The beginning, end and length of each branch shows when they lived, and, the thickness of branches provides a symbolic representation of the relative abundance or scarcity of those animals during each period of geological time. Laminated. Size: 24" x 36".
