Taxonomy - Taxonomy - A classification of living organisms: Recent advances in biochemical and electron microscopic techniques, as well as in testing that investigates the genetic relatedness among species, have redefined previously established taxonomic relationships and have fortified support for a five-kingdom classification of living organisms. This alternative scheme is presented below.

Mitochondrial genome of Trichoplax adhaerens supports placozoa as the basal lower metazoan phylum. Proceedings of the National Academy of Sciences (U.S.A.) 103(23):8751-8756. Ender, A. and B. Schierwater. 2003. Placozoa are not derived cnidarians: Evidence from molecular morphology. Molecular Biology and Evolution 20(1):130-134. Grell, K. G.

The enigmatic animal phylum Placozoa holds a key position in the metazoan Tree of Life. A simple bauplan makes it appear to be the most basal metazoan known and genetic evidence also points to a position close to the last common metazoan ancestor. Trichoplax adhaerens is the only formally described species in the phylum to date, making the Placozoa the only monotypic phylum in the animal.

There is no convincing fossil record of the placozoa, although the Ediacaran biota (Precambrian, 550 million years ago) organism Dickinsonia appears to be closely allied with this phylum. (5)Traditionally, classification has been based on their level of organization: i.e. they possess no tissues or organs.

Placozoa Balloon -like marine animals, the placozoans, believed to be the simplest organism in Animalia. A taxonomic phylum within the subkingdom Agnotozoa.

There is no convincing fossil record of the placozoa, although the Ediacaran biota (Precambrian, 550 million years ago) organism Dickinsonia may be allied with this phylum. Traditionally, classification was based on their level of organization: i.e. they possess no tissues or organs.

History of classification. The scientific validity of the term coelenterate is currently disputed, as the Cnidaria and Ctenophora have less in common than previously assumed. Coelentera may only be monophyletic if both Placozoa and Bilateria are included. In particular, the phylogenetic position of Ctenophora is controversial; it was first considered a sub-group of coelenterata but Hyman.

Animal testing is already controlled to a great extent. Many cats and dogs are killed annually by shelters and pounds. Animal testing is not as cruel as it is portrayed and is an essential to reaching medical breakthroughs. Special controls on laboratory animals have been in place since 1876. These have been revised in 1986. These laws are now.
