1. The TRPM family of ion channels has members throughout the metazoa . 2. Overall however, the basal relationships of Metazoa are not yet well resolved. 3. Thus Metazoa is now considered a synonym of Animalia. 4. This subunit may have an analogous function in Metazoa . 5. However, evidence of Precambrian Metazoa is gradually accumulating. 6. The protozoa were later moved to the kingdom Protista, leaving only the metazoa . 7. Animals throughout metazoa have various combinations of these. 8. It is thus paraphyletic to vertebrates, provided that you accept a monophyletic Metazoa . 9. The first three enzymes are all coded by the same gene in Metazoa ( CAD ). 10. They may have represented cnidaria, but their affinity within the Metazoa is difficult to constrain.
