Abstract
When Brooks Parsimony Analysis (BPA) or Parsimony Analysis of Endemicity (P AE) is performed under Wagner Parsimony, some branches in the resulting res olved area cladogram(s), may be supported by reversals, interpreted as exti nctions. Such support is meaningless, so one may perform the analysis with irreversible characters. This, in turn, will increase the number of indepen dent forward character changes on the resolved area cladogram(s) which can also be problematical in BPA, but not in PAE.
