Function
Interactive mixed method parsimonyDescription
Interactive construction of phylogenies from discrete character data with two states (0 and 1). Evaluates parsimony and compatibility criteria for those phylogenies and displays reconstructed states throughout the tree. This can be used to find parsimony or compatibility estimates by hand.Algorithm
MOVE is an interactive parsimony program, inspired by Wayne Maddison and David Maddison's marvellous program MacClade, which is written for Apple Macintosh computers. MOVE reads in a data set which is prepared in almost the same format as one for the mixed method parsimony program MIX. It allows the user to choose an initial tree, and displays this tree on the screen. The user can look at different characters and the way their states are distributed on that tree, given the most parsimonious reconstruction of state changes for that particular tree. The user then can specify how the tree is to be rearraranged, rerooted or written out to a file. By looking at different rearrangements of the tree the user can manually search for the most parsimonious tree, and can get a feel for how different characters are affected by changes in the tree topology.This program is compatible with fewer computer systems than the other programs in PHYLIP. It can be adapted to MSDOS systems or to any system whose screen or terminals emulate DEC VT100 terminals (such as Telnet programs for logging in to remote computers over a TCP/IP network, VT100-compatible windows in the X windowing system, and any terminal compatible with ANSI standard terminals). For any other screen types, there is a generic option which does not make use of screen graphics characters to display the character states. This will be less effective, as the states will be less easy to see when displayed.
MOVE uses as its numerical criterion the Wagner and Camin-Sokal parsimony methods in mixture, where each character can have its method specified separately. The program defaults to carrying out Wagner parsimony.
The Camin-Sokal parsimony method explains the data by assuming that changes 0 --> 1 are allowed but not changes 1 --> 0. Wagner parsimony allows both kinds of changes. (This under the assumption that 0 is the ancestral state, though the program allows reassignment of the ancestral state, in which case we must reverse the state numbers 0 and 1 throughout this discussion). The criterion is to find the tree which requires the minimum number of changes. The Camin- Sokal method is due to Camin and Sokal (1965) and the Wagner method to Eck and Dayhoff (1966) and to Kluge and Farris (1969).
Here are the assumptions of these two methods:
- Ancestral states are known (Camin-Sokal) or unknown (Wagner).
- Different characters evolve independently.
- Different lineages evolve independently.
- Changes 0 --> 1 are much more probable than changes 1 --> 0 (Camin-Sokal) or equally probable (Wagner).
- Both of these kinds of changes are a priori improbable over the evolutionary time spans involved in the differentiation of the group in question.
- Other kinds of evolutionary event such as retention of polymorphism are far less probable than 0 --> 1 changes.
- Rates of evolution in different lineages are sufficiently low that two changes in a long segment of the tree are far less probable than one change in a short segment.
That these are the assumptions of parsimony methods has been documented in a series of papers of mine: (1973a, 1978b, 1979, 1981b, 1983b, 1988b). For an opposing view arguing that the parsimony methods make no substantive assumptions such as these, see the papers by Farris (1983) and Sober (1983a, 1983b), but also read the exchange between Felsenstein and Sober (1986).
