Phylogenetic signal calculated from 91,859 CHR2 insertions in baleen whales. a Neighbor-Joining tree based on CHR2 insertions. All nodes received bootstrap values of 95% or higher (100% shown as asterisk). b Percentage of variation explained by principal components 1–10 in the PCA. c Scatterplot of the first two principal components (PC1 and PC2) among baleen whale genomes
