Algorithm

DNAMOVE is an interactive DNA parsimony program, inspired by Wayne Maddison and David and Wayne Maddison's marvellous program MacClade, which is written for Macintosh computers. DNAMOVE reads in a data set which is prepared in almost the same format as one for the DNA parsimony program DNAPARS. It allows the user to choose an initial tree, and displays this tree on the screen. The user can look at different sites and the way the nucleotide 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 sites are affected by changes in the tree topology.

This program uses graphic characters that show the tree to best advantage on some computer systems. Its graphic characters will work best on MSDOS systems or MSDOS windows in Windows, and to any system whose screen or terminals emulate ANSI standard terminals such as old Digital VT100 terminals, Telnet programs, or VT100-compatible windows in the X windowing system. For any other screen types, (such as Macintosh windows) there is a generic option which does not make use of screen graphics characters. The program will work well in those cases, but the tree it displays will look a bit uglier.

This program carries out unrooted parsimony (analogous to Wagner trees) (Eck and Dayhoff, 1966; Kluge and Farris, 1969) on DNA sequences. The method of Fitch (1971) is used to count the number of changes of base needed on a given tree.

The assumptions of this method are exactly analogous to those of MIX:

1. Each site evolves independently.
2. Different lineages evolve independently.
3. The probability of a base substitution at a given site is small over the lengths of time involved in a branch of the phylogeny.
4. The expected amounts of change in different branches of the phylogeny do not vary by so much that two changes in a high-rate branch are more probable than one change in a low-rate branch.
5. The expected amounts of change do not vary enough among sites that two changes in one site are more probable than one change in another.

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).

Change from an occupied site to a deletion is counted as one change. Reversion from a deletion to an occupied site is allowed and is also counted as one change.
