New and comprehensive molecular research confirms a deep evolutionary division among animals. This new tree of life divides all so-called "lower" metazoans (Placozoa, corals, sponges, and jellyfish) from "higher" animals (all other metazoans, from flatworms to chordates). Placozoans have also passed over comb jellies and other organisms as an animal that most closely mirrors the root of this tree of life.
