Hierarchical clustering of the expression of the core genes for the eight samples. The distance between the samples is 1-the Spearman correlation between the samples. Numbers on the branches represent the number of genes that were differentially expressed in each lineage with evolutionarily consistent relationships, e.g. 226 genes were differentially expressed in the S. bayanus lineage vs. each other lineage.
