About MEGA, the Molecular Evolutionary Genetics Analysis Software


MEGA is an integrated tool for conducting automatic and manual sequence alignment, inferring phylogenetic trees, mining web-based databases, estimating rates of molecular evolution, and testing evolutionary hypotheses.

With its theoretical basis firmly established in molecular evolutionary and population genetics, comparative sequence analysis has become essential for reconstructing the evolutionary histories of species and multi-gene families, estimating the rates of molecular evolution, and inferring the nature and extent of selective forces shaping the evolution of genes and genomes.

From its inception, the goal of MEGA has been to make available a wide variety of statistical and computational methods for comparative sequence analysis in a user-friendly environment. A survey of research papers citing MEGA reveals that the software is used in diverse disciplines, including AIDS/HIV research, virology, bacteriology and general disease, plant biology, conservation biology, systematics, developmental evolution, and population genetics.
