MEGA, which stands for Molecular Evolutionary Genetics Analysis, is an intuitive and highly capable software suite tailored for examining DNA and protein sequence information from various species and populations. It allows for both automated and manual alignment of sequences, the construction of phylogenetic trees, and the testing of evolutionary theories. The software employs an array of statistical approaches such as maximum likelihood, Bayesian inference, and ordinary least squares, making it indispensable for comparative sequence analysis and insights into molecular evolution. Additionally, MEGA includes sophisticated functionalities like real-time caption generation to clarify the findings and methodologies applied during analysis, alongside the maximum composite likelihood method for calculating evolutionary distances. The program is enhanced with powerful visual aids, including an alignment/trace editor and a tree explorer, while also supporting multi-threading to optimize processing efficiency. Furthermore, MEGA is compatible with several operating systems, such as Windows, Linux, and macOS, ensuring accessibility for a diverse user base. In summary, MEGA stands out as a comprehensive tool for researchers delving into the intricacies of molecular genetics.
