One reliable method of building and evaluating trees, called parsimony, involves grouping taxa together in ways that minimize the number of evolutionary changes that had to have occurred in the characters.The idea here is that, all other things being equal, a simple hypothesis (e.g., just four evolutionary changes) is more likely to be true than a more …els of sequence divergence are as low as 10%; parsimony incorrectly infers an excess of common to rare changes.
