Character Matrix Methods
1.Parsimony is the most popular method for reconstructing ancestral
relationships.
2.Parsimony allows the use of all known evolutionary information in tree.
3.The phylogenetic topology tree is constructed by using a cluster analysis method (like MP or ML methods).
4.Approaches involve  two components:
•A search through space of trees.
•A procedure to find the minimum number of changes needed to explain the data – used for scoring each tree.
