The Myriochelata is a clade consisting of the Myriapoda (millipedes, and centipedes) and Chelicerata (spiders and scorpians). A clade is a taxonomic group comprising a single Common ancestor and all the descendants of that ancestor Myriapoda is a Subphylum of Arthropods containing Millipedes Centipedes and others Millipedes (Class Diplopoda, previously also known as Chilognatha are Arthropods that have two pairs of legs per segment (except for the first segment behind Centipedes (from Latin prefix centi-, "hundred" and Greek ποδός podos, " Foot " are The subphylum Chelicerata constitutes one of the major subdivisions of the phylum Arthropoda including the Arachnids Horseshoe crabs and related forms Spiders are Predatory Invertebrate Animals that have two body segments, eight legs no chewing mouth parts and no wings Scorpions are eight-legged Carnivorous Arthropods They are members of the order Scorpiones within the class Arachnida. It is the sister clade to the Tetraconata. The Tetraconata is a Clade consisting of the Crustacea ( crabs, Lobsters, and Shrimp) and Hexapoda ( Insects) Another name for Myriochelata is Paradoxopoda.
The evidence for this clade derives from molecular data and morphological characteristics. The molecular data consists of comparisons of nuclear ribosomal RNA genes, mitocondrial ribosomal RNA genes, and protein coding genes. In Cell biology, the nucleus (pl nuclei; from Latin la ''nucleus'' or la ''nuculeus'' "little nut" or kernel is a membrane-enclosed Ribosomal RNA ( rRNA) is the central component of the Ribosome, the protein manufacturing machinery of all living cells. History See also History of genetics The existence of genes was first suggested by Gregor Mendel (1822-1884 who in the 1860s studied inheritance In Cell biology, a mitochondrion (plural mitochondria) is a membrane-enclosed Organelle found in most eukaryotic cells. Proteins are large Organic compounds made of Amino acids arranged in a linear chain and joined together by Peptide bonds between the Carboxyl
