Vandenabeele et al. show that the numerous phylogenetic incongruences among gene tree topologies in orchids result from pervasive ILS, over which stand out several well-supported, ancient and potentially adaptive gene flow events between lineages.

Phylotranscriptomics Allows Distinguishing Major Gene Flow Events from Incomplete Lineage Sorting in Rapidly Diversifying Mimetic Orchids (Genus Ophrys)
Abstract. Ophrys orchids (or bee orchids) provide an outstanding example of a plant adaptive radiation. Over the last 5 million years, this genus has diver
