Why To Study Evolution?

in Phylogenetics by

Understanding evolution is critical for understanding biology. As the preeminent scientist Theodosius Dobzhansky stated, “Nothing in biology makes sense except in the light of evolution.” Evolution is the only scientific explanation for the diversity of life. It explains the striking similarities among vastly different forms of life, the changes that occur within populations, and the development of new life forms. Excluding evolution from the science curricula or compromising its treatment deprives students of this fundamental and unifying scientific concept to explain the natural world.

MEGA: Molecular Evolutionary Genetic Analysis
It is important to know the basic molecular relationship between two living organisms as one begins performing comparative studies for knowing the evolutionary aspects and for contributing to knowledge base. Several tools and soft ware have been introduced for meeting the task of such analysis. Each tool has different algorithm and method to perform molecular phylogeny. Examples include; ClustalW, Dendroscope, Hyphy, PAUP and Phylip etc. Among them is the most efficient tool, MEGA, Molecular evolutionary phylogenetic analysis which performs both sequence analysis and phylogenetic analysis in a very sophisticated manner.

Monogenea: An Easy Portfolio for Molecular Phylogenetics

in Phylogenetics by

Estimation of present day diversity of organism and understanding their diversity forms new cornerstones of conservation biology, evolutionary biology and ecology. Maintaining the totality of all texa from past to present and classifying into groups reflect how they have changed over the period of times. Necessarily, phylogenetics and evolutionary study of a particular group help out in knowing pattern of occurrence and relationships between two distantly related class or families and their descendents.
