WebA widely accepted hypothesis, based on molecular data (mostly 18S rRNA sequences), divides Bilateria into four superphyla: Deuterostomia, Ecdysozoa, Lophotrochozoa, and Platyzoa (sometimes included in Lophotrochozoa). The last three groups are also collectively known as Protostomia. [citation needed] 魚スギレシピWebThe Lophotrochozoa are a diverse group of phyla with similar ribosomal RNA sequences.

Lophotrochozoa is a clade of protostome animals within the Spiralia. The taxon was established as a monophyletic group based on molecular evidence. The clade includes animals like annelids, molluscs, bryozoans, brachiopods, and platyhelminthes. WebEcdysozoa and Lophotrochozoa are protostomes; however, the two lineages diverged soon after the protostomes/deuterostomes split. Thus, an evolutionary perspective needs an example from the Lophotrochozoa. Mollusks are the largest group in this taxon and are also the most diverse.
