Maximum parsimony

In evolutionary biology, maximum parsimony is a method used to build phylogenetic trees based on the principle of simplicity. Under the maximum-parsimony criterion, the best tree will minimize the amount of homoplasy (i.e., convergent evolution, parallel evolution, and evolutionary reversals). In other words, under this criterion, the optimal tree has…
