In this article, we describe how to collect data from GenBank, insert it into a text editor, import that data into MEGA, and create phylogenetic trees from the collected data Key Words: MEGA, evolutionary trees, molecular data, Neighbor-Joining, Maximum-likelihood Phylogenetics is the study of the evolutionary relatedness between different groups of organisms (Nei and Kumar 2000). There are several different options to choose from when building trees from molecular data in MEGA, but the most commonly used are Neighbor-Joining and Maximum Likelihood, both of which give good estimates on the relationship between different molecular sequences. Molecular Evolutionary Genetics Analysis (MEGA) software is a free package that lets anyone build evolutionary trees in a user-friendly setup.
