Chordates consist of three distinct animal groups: cephalochordates, urochordates (tunicates) and vertebrates. This review starts with a brief description of how the Phylum Chordata and its three subphyla were originally defined, and then discusses how we should reclassify the major chordate groups. 2.

7 paź 2008 · Introduction. Chordata, a taxon consisting of about 50 000 animals, includes Homo sapiens, our own species, and it might be for this latter reason that the interest in understanding the evolution of chordates never ceased.
chordates have established themselves as one of the major animal phyla, with dominance of the water, land, and air. They cannot rival arthropods in terms of numbers of either species or individuals, but outstrip them in terms of total biomass and ecological dominance. Chordates are coelomates, and as such are another
The Chordata is a monophyletic group consisting of three living phyla: Cephalochordata, Urochordata, and Vertebrata. Morphology-based studies on the origin and evolution of the chordates suggested that the segmented and unsegmented urochordates were sister groups.
