The classification system introduced by Carl Linnaeus in 1735, which grouped species by phyla, orders and families has become obsolete due to the widespread adoption of the new Cladistics classification system, which is based on the development of physical characteristics and arranges organisms by their order of branching in an evolutionary tree. It has been used in most universities and colleges since the late 1990s and is now finding it ways into the grade schools. This new poster shows this new system.  Simultaneous with this revolutionary change in classification systems, many new species have been discovered. Some have been so unique, that they have been given their own phylum / clade.  This poster includes living species and the extinct ones. The result is a comprehensive overview of all life that has lived on Earth. The number of phyla / clades has jumped from 27 to 41.   Animal Kingdom 2 has been closely coordinated with our new Animal Development Poster. The latter shows the physical changes that have taken place in animals and the resulting cladistic family tree. Animal Kingdom then provides the details of each phylum.  These changes and improvements result in a quantum leap presentation. These posters are sure to become indispensable references for both students and professionals. They will be useful for the botanists and zoologists, but also the various paleo scientists.


Animal Development, Milestones of Evolution and our Animal Kingdom 2 are designed to be used both individually and together. Animal Development focuses on the invertebrates and Milestones of Vertebrate Evolution picks up where it leaves off. Both show how the various clades evolved; Animal Kingdom show the results. Teachers, students and professionals will find them to be an invaluable reference.
