some data: H1 mtDNA extracted from a young man 17-25 years old, inhumated with elephant's ivories (Asiatic and African!) and also sicilian amber; no Y-DNA available; he was inhumated in the megalith of Montelirio (Valencina de la Concepción, Seville); dated 3000 BCE; the authors explain that there was a 10% of non autochtonous population in the near village. I can't provide any scientific paper with details, sorry. Quite impressive the imported items...
