A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
The NEXUS format also allows the storage of data that can facilitate analyses, such as sets of characters or taxa. Many popular phylogenetic programs, including PAUP*, [2] MrBayes, [3] Mesquite, [4] MacClade, [5] and SplitsTree, [6] use this format. Nexus file names typically have the extension .nxs or .nex.
