In terms of tree-building, that means that, all other things being equal, the best hypothesis is the one that requires the fewest evolutionary changes. WebThe tree length is then computed for all possible topologies, and the topology that shows the smallest tree length is chosen as the final tree (maximum parsimony tree).

Equally parsimonious trees

A maximum parsimony analysis runs in a very straightforward fashion. Trees are scored according to the degree to which they imply a parsimonious distribution of the character data. The most parsimonious tree for the dataset represents the preferred hypothesis of relationships among the taxa in the analysis. Trees are scored (evaluated) by using a simple algorithm to determine how many "steps" (evolu… Webparsimony method with multiple states. Wagner parsimony allows changes among all states. The criterion is to find the tree which requires the minimum number of changes. The Wagner method was originated by Eck and Dayhoff (1966) and by Kluge and Farris (1969). Here are its assumptions: Ancestral states are unknown.
