Phylogenetic relationships under a relaxed clock. The phylogenetic tree generated when substitution rates among lineages are allowed to vary. The tree shows H. himera nested within the H. erato radiation. Results for Bayesfactor comparison of strict and relaxed molecular clock topologies are shown in upper left corner. (PNG 109Â kb
