Adaptive genetic markers identify the origins and dispersal of invasive species

The western area of the Iberian Peninsula could be determinant in the origin of the ancestral population of Drosophila subobscura, an invasive species widely spread across multiple latitudes. This is the conclusion of a study of adaptive genetic markers now published in the journal Proceedings of the Royal Society B, which was led by Marta Pascual from the Faculty of Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona.
