“Ibiza is different.” That is what the hundreds of standard-bearers of the “hippie” movement who visited the Pitiusan Island during the 60s thought, fascinated by its climate and its unexplored nature. What they did not imagine was that the most unique feature of the island was in its inhabitants. Now a study led by Francesc Calafell, principal investigator of the Institute of Evolutionary Biology (IBE) – a mixed center of the UPF and the Consejo Superior de Investigaciones CientÃficas (CSIC) reveals that the genes of Ibiza natives are really different. Yes indeed, the island is unique.
