Mark Wilkinson's Phylogenetics Programs

You can download the latest versions of my phylogenetic software by clicking on the name of the software package below. Each package includes DOS executables that can be run under DOS or in a DOS box under Windows, example input files, and a manual in PDF format. The packages are compressed with WINZIP and files will need to be extracted using this or a similar utility once downloaded.
