WebThis program carries out the Fitch-Margoliash and Least Squares methods, plus a variety of others of the same family, with the assumption that all tip species are contemporaneous, and that there is an evolutionary clock (in effect, a molecular clock). WebFitch-Margoliash Neighbor joining 34 Phylogenetics-DistanceMethods - March 28, 2024.
