In biology, a phylum (/ˈfaɪləm/; pl.: phyla) is a level of classification or taxonomic rank below kingdom and above class. Traditionally, in botany the...

The Bilateria has traditionally been divided into two main lineages or superphyla. The deuterostomes traditionally include the echinoderms, hemichordates...

bilaterally symmetric body plan. The vast majority belong to two large superphyla: the protostomes, which includes organisms such as the arthropods, molluscs...

molecular data (mostly 18S rRNA sequences), divides Bilateria into four superphyla: Deuterostomia, Ecdysozoa, Lophotrochozoa, and Platyzoa (sometimes included...

phyla consistently cluster together and are referred to as supergroups or superphyla. In some instances, bacterial clades clearly consistently cluster together...

18 S rRNA gene provides information on relationships among phyla and superphyla, while the ITS2, and the 18S ribosomal RNA and 28S ribosomal RNA genes...

Ecdysozoa (/ˌɛkdɪsoʊˈzoʊə/) is a group of protostome animals, including Arthropoda (insects, chelicerata (including arachnids), crustaceans, and myriapods)...

events that occur very early in embryonic development, into two groups (superphyla) called protostomes and deuterostomes. Deuterostomes include vertebrates...

genomic analyses have supported the division of Bacteria into two major superphyla, corresponding to Terrabacteria and Hydrobacteria. The phylogenetic tree...

A seed plant or spermatophyte (lit. 'seed plant'; from Ancient Greek σπέρματος (spérmatos) 'seed' and φυτόν (phytón) 'plant'), also known as a phanerogam...

groups. Annelids are members of the protostomes, one of the two major superphyla of bilaterian animals – the other is the deuterostomes, which includes...

Asgard or Asgardarchaeota is a proposed superphylum consisting of a group of archaea that contain eukaryotic signature proteins. It appears that the eukaryotes...

Deuterostomes (from Greek: lit. 'mouth second') are bilaterian animals of the superphylum Deuterostomia (/ˌdjuːtərəˈstoʊmi.ə/), typically characterized...

These studies found the following phylogeny between phyla and superphyla. The superphyla are shown in bold. However, several recent studies have suggested...
