Parsimony methods evaluation

Bootstrapping is a resampling tree evaluation method that works with distance, parsimony, likelihood, and just about any other tree derivation method. It was invented in 1979 (Efron, 1979) and introduced as a tree evaluation method in phylogenetic analysis by Felsenstein (1985). The result of bootstrap analysis is typically a number associated with a particular branch in the phylogenetic tree that gives the proportion of bootstrap replicates that supports the monophyly of the clade. 

Sequence-based phylogenies are determined using an parsimony algorithm (Cedergren al.. 1988). Most parsimonious solutions are evaluated using a bootstrapping technique and occasionally branch points are validated by the invariants method of Cavender and Felsenstein (1987) and of Lake (1987).
