Phoronids, brachiopods and bryozoans (ectoprocts) have collectively been called lophophorates, because all use lophophores to feed. This indicates that brachiopods and phoronids together form sister groups at the base of all other lophotrochozoan phyla. By contrast, molecular data have consistently indicated that the three lophophorate lineages, Ectoprocta, Brachiopoda and Phoronida, are more closely related to trochozoans (annelids, molluscs and related groups) than to deuterostomes. lophophore, proves an affinity between Brachiopoda, Bryozoa (Ectoprocta) and Phoronida, which is implied by several authors by referring them to Lophophorate phyla. Modern lophophorates are quite diverse-some can biomineralize while others are soft-bodied, they could be The experimental insertion of a monophyletic taxon consisting of Brachiopoda and Phoronida into a widely accepted phylogenetic tree of Spiralia leads to the hypothesis that at least trimeric organization, mesosomal tentacular apparatus and heterogeneously assembled metanephridia are products of convergent evolution in Brachiopoda plus Phoronida Dec 1, 2006 · PDF | On Dec 1, 2006, Francisco Sour-Tovar published Fauna Ibérica, volumen 27.

To shed further light on this issue, we present phylogenomic analyses of 196 genes from 58 bilaterian taxa, paying particular attention to the influence of compositional heterogeneity. Feb 7, 2000 · Brachiopod–phoronid monophyly is reconciled with the most recent Linnaean classification of brachiopods by abolition of the phylum Phoronida and rediagnosis of the phylum Brachiopoda to include tubiculous, shell–less forms. They occur in abundance in a few places only, such as off southern Australia, New Zealand, and parts of Japan. The Annelida, Mollusca, Entoprocta, Phoronida, Nemertea, Brachiopoda, and Sipuncula (i.

With the help of functional morphology data we are May 1, 2011 · The reiteration of monophyly of brachiopods and phoronids could be used to resurrect an early hypothesis that argued brachiopods originated from a tubiculous phoronid-like ancestor 22,34 . We screened transcriptomes from 13 nemertean, 6 brachiopod, and 4 phoronid species for proneuropeptides and neuropeptide GPCRs. Sep 1, 2008 · By contrast, molecular data have consistently indicated that the three lophophorate lineages, Ectoprocta, Brachiopoda and Phoronida, are more closely related to trochozoans (annelids, molluscs and The experimental insertion of a monophyletic taxon consisting of Brachiopoda and Phoronida into a widely accepted phylogenetic tree of Spiralia leads to the hypothesis that at least trimeric organization, mesosomal tentacular apparatus and heterogeneously assembled metanephridia are products of convergent evolution in Brachiopoda plus Phoronida May 20, 2008 · By contrast, molecular data have consistently indicated that the three lophophorate lineages, Ectoprocta, Brachiopoda and Phoronida, are more closely related to trochozoans (annelids, molluscs and related groups) than to deuterostomes.
