Evidence for a clade of nematodes, arthropods and other moulting animals
Article Abstract:
Arthropods are a diverse animal group and have been subject to much study, but their phylogenetic links are still unclear. The relationships of arthropods to other taxa are analysed through the sequencing of entire 18S rDNAs of representative taxa, aligned with existing 18S sequences of metazoan taxa. Standard phylogenetic techniques were used, and a close link between arthropods, nematodes and other moulting phyla is indicated.

Article Abstract:
Studies were conducted to analyze flows of gene populations and reveal the complex genetic and evolutionary connections between eukaryotes and prokaryotes. Results reveal that the complexity hypothesis attributes the reduced transfer rate, seen in informational genes partly to the observation that their proteins are often deeply integrated into large complexes such as the ribosome.
