Among the three extant (living) genera, Asymmetron is basal and it is placed in its own family. 2016-01-01 · The shared presence of the 2 aa conserved deletion by all of the vertebrates and tunicates, but not by cephalochordates, supports the view that tunicates are more closely related to the vertebrates, and that the genetic change responsible for this CSI occurred in a common ancestor of the vertebrates and tunicates. 2006-02-23 · Tunicates or urochordates (appendicularians, salps and sea squirts), cephalochordates (lancelets) and vertebrates (including lamprey and hagfish) constitute the three extant groups of chordate The tunicates, or urochordates, constitute a large group of marine animals whose recent common ancestry with vertebrates is reflected in the tadpole-like larvae of most tunicates. Their diversity and key phylogenetic position are enhanced, from a research viewpoint, by anatomically simple and transparent embryos, compact rapidly evolving genomes, Today it is well established that tunicates along with cephalochordates and vertebrates comprise the phylum Chordata. These three groups share several morphological features that characterize them, such as the presence of the notochord, a dorsal neural tube, gill slits, and the endostyle (Malcolm 1962). Some tunicates are fouling organisms that grow on ships’ hulls. Their main interest to humans is in providing clues to the possible ancestry of vertebrates.
