WebThe D (methods) option allows choice between the Fitch-Margoliash criterion and the Minimum Evolution method (Kidd and Sgaramella-Zonta, 1971; Rzhetsky and Nei, 1993). Minimum Evolution (not to be confused with parsimony) uses the Fitch-Margoliash criterion to fit branch lengths to each topology, but then chooses topologies based on their total ...
WebEmanuel Margoliash (February 10, 1920 – April 10, 2008) was a biochemist who spent much of his career studying the protein cytochrome c. He is best known for his work on molecular evolution ; with Walter Fitch , he devised the Fitch-Margoliash method for constructing evolutionary trees based on protein sequences .

WebFitch launched a notable research collaboration that led to the construction of phylo-genetic trees based on protein sequences. With 10 published amino acid sequences of Cytochrome c and 10 more yet unpublished sequences from Margoliash’s lab, Fitch and Margoliash assembled a phylogenetic tree of 20 species that spanned yeast, insects, fish, WebLemma 1). In fact, both the Cavalli-Sforza and Edwards criterion and the Fitch and Margoliash criterion lead to computationally intractable problems.
