Distribution of the number of sites grouping preferentially Porifera+Cnidaria or Eumetazoa. Bars are drawn in purple or in blue, for Porifera+Cnidaria and Eumetazoa, respectively. Sites are counted for the complete alignment and the five subsets obtained by progressive removal of the most heteropecillous sites for the mt68 dataset.
