Abstract
Here we reconstruct the evolutionary history of Micromeria in the Canary Islands using eight nuclear markers. Our results show two centers of diversification for Micromeria, one in the eastern islands Gran Canaria and Lanzarote, the other in the western islands, Tenerife, La Palma and El Hierro. Suggested directions of inter-island colonization are the following: Gran Canaria to Lanzarote and La Gomera; Tenerife to La Palma (from the paleoisland of Teno), to El Hierro (from the younger, central part), and to La Gomera and Madeira (from the paleoislands). Colonization of La Gomera probably occurred several times from Gran Canaria and Tenerife. The taxonomic implications of these results are discussed. Incongruence among the different markers was evaluated and, using next generation sequencing, we investigated if this incongruence is due to gene duplication.

The authors thank the University of La Laguna in Tenerife for facilitating a car for the collection of the plant material in Gran Canaria, Tenerife, and La Gomera during 2010–2012. Francisco Faure was an important help during field work. Victor Garzón-Machado provided the map that served as base for Fig. 4 . Saurabh Dilip helped with the de novo genome assembly and Blast analyses. Guillermo Velo-Antón helped with the BEAST run. Peter Stevens helped improve the English. The authors also thank the two anonymous reviewers who helped improve this manuscript with their helpful comments and suggestions.
