Abstract
Mutualisms, interactions between species that are beneficial to both partners, are useful
systems for investigating how interactions may affect the evolution and diversification of lineages. Interactions between ants and plant species of the genus Cecropia are a classic example of mutualism but the origin and evolution of the mutualism is poorly understood. We examined whether the inclusion of an exon-primed intron-crossing (EPIC) marker could improve our understanding of Cecropiaeae phylogeny. We performed a Bayesian phylogenetic analysis of 15 species from which EPIC sequences were obtained (Fig. 2).
By comparing clade support from analyses with and without EPIC, we concluded that the addition of a third gene region strongly supports the hypothesis that the Afrotropical and antless genus Musanga was derived from a Cecropia ancestor and is most closely related
to the antless neotropical species C. sciadophylla (Fig. 1).
