Secondary gene flow in the Müllerian mimicry ring of a poisonous Papuan songbird clade (Pitohui; Aves)

Müllerian mimicry rings are remarkable symbiotic assemblages of species which have evolutionary converged on a similar phenotype that becomes advantageous only when exhibited by a critical mass of individuals. However, the evolutionary origin of most Müllerian mimicry rings remains poorly understood. In this study, we investigated the evolutionary history of multiple members of a passerine mimicry ring in the poisonous Papuan pitohuis.
