Figure 6From: Site-specific time heterogeneity of the substitution process and its impact on phylogenetic inferenceDistribution 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.Back to article page
