Most of the times, it is a very tedious job to convert file formats in bioinformatics, especially when we are dealing with phylogeny. Most of the available online servers mess your file and the output format is also not supported by the other programs. Additionally, it is quite difficult to perform other customizations on the phylogeny tree. Continue reading “Most widely used tools for phylogenetic tree customization” »
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.
