Fig 5. Hypothesis for the origins and introgression of the dennis and ray regions inferred from dated trees.

Fig 5

Key events indicated on the x-axis are (A) introgression of dennis from H. elevatus into H. melpomene, inferred from the coalescence time of alleles sampled from these two species; (B) the origin of ray alleles within H. melpomene, inferred from the coalescence of dennis and non-dennis alleles within H. melpomene; (C) introgression of ray into H. timareta; (D) introgression of ray into H. elevatus, and (E) introgression of dennis into H. timareta. Dating of phylogenies was carried out using BEAST, and full dated trees with support limits are provided in S3 Fig. The species tree is derived from [14].
