A Combination Study in Some Members of Monocotylidae (Monogenea) in Molecular Phylogeny Employing 28SrRNA along with Geographical Distribution

Evolution and interrelatedness among the same group of organism have been explored and debated in many ways. Traditional tools of phylogenetic investigation presented preferred scene for a considerable time. The stage was taken by the incorporation of molecular tools in later stages. Considering a combination of host specific parasite may be more informative in terms of investigating evolutionary lineage of an organism. Recently attempts have been made to incorporate secondary rRNA structure for consideration of phylogenetic studies. Present investigation is an attempt to investigate a family i. e. , Monocotylidae (Class Monogenea) for the same. Cues from geographical distribution and molecular tools have been employed in the study. The finding supports that host play substantial role in the formation of new species. Species distribution strengthened intra genus relationship, divergence and migration over period of times.
