متن کاملA cladistic analysis of the Trichostrongyloidea (Nematoda).
A morphologically based cladistic analysis of 40 genera included within the Trichostrongyloidea (Amidostomatidae, Dromaeostrongylidae and Trichostrongylidae) is proposed. Two genera were used as outgroups, one from the Strongylina and the other from the Ancylostomatina. Seven genera do not appear in the matrix because some significant morphological characters remain unknown for these genera. No...
متن کاملCladistic analysis reveals brainless urbilateria.
sister groups by any stretch of the imagination. In a very elegant paper, Moroz [2009] reviews the literature, subjects the data to a correct cladistic analysis, and concludes that centralized nervous systems have evolved independently, perhaps as many as seven times. In a particularly striking example, he demonstrates that complex brains have evolved at least three times in molluscans alone. H...
متن کاملCladistic analysis of Medusozoa and cnidarian evolution
A cladistic analysis of 87 morphological and life history characters of medusozoan cnidarians, rooted with Anthozoa, results in the phylogenetic hypothesis (Anthozoa (Hydrozoa (Scyphozoa (Staurozoa, Cubozoa)))). Staurozoa is a new class of Cnidaria consisting of Stauromedusae and the fossil group Conulatae. Scyphozoa is redefined as including those medusozoans characterized by strobilation and ...
متن کاملCladistic Analysis of Olfactory and Vomeronasal Systems
Most tetrapods possess two nasal organs for detecting chemicals in their environment, which are the sensory detectors of the olfactory and vomeronasal systems. The seventies' view that the olfactory system was only devoted to sense volatiles, whereas the vomeronasal system was exclusively specialized for pheromone detection was challenged by accumulating data showing deep anatomical and functio...
