Modern day Ethiopians show great cultural, linguistic and historical diversity
According to fossil evidence, human history goes back longer in Ethiopia than anywhere else in the world. But little has been known until now about the human genetics of Ethiopians.
Professor Chris Tyler-Smith of the Wellcome Trust Sanger Institute in Cambridge, UK, a researcher on the study, told BBC News: "Genetics can tell us about historical events.
"By analysing the genetics of Ethiopia and several other regions we can see that there was gene flow into Ethiopia, probably from the Levant, around 3,000 years ago, and this fits perfectly with the story of the Queen of Sheba."

Lead researcher Luca Pagani of the University of Cambridge and the Wellcome Trust Sanger Institute added: "The genetic evidence is in support of the legend of the Queen of Sheba."
