This learning material is a series of phylogenies (evolutionary branching diagrams) that shows the extant lineages of the chordates, bony vertebrates, and mammals. The diagrams are printable on letter-size paper. The whole series can be joined with yarn to show the branching of mammals to orders and the further branches of four orders, including primates. The set includes lessons for introducing the branches and research cards for children that include the derived features and the sister branch or branches. The set is available as a print-it-yourself file.
