We just mentioned that the principle of parsimony is often useful in reconstructing evolutionary trees.ypothesis 1 requires six evolutionary changes and Hypothesis 2 requires seven evolutionary changes, with a bony skeleton evolving independently, twice. Although both fit the available data, the parsimony principle says that Hypothesis 1 is better  since it does not hypothesize unnecessarily complicated changes.
