Parsimony (Molecular Biology). Parsimony is one of the principles of phylogenetic tree reconstruction in which the phylogeny of a group of species or genes is inferred to be the branching pattern that requires the smallest number of evolutionary changes (1).he merit of using the parsimony principle is that we can infer the amino acid or nucleotide sequences of all the intermediate stages in the continuous lineage between the ancestor and the present species. The intermediate stages may be trustworthy, however, only when closely-related genes are compared.
