Arabia the First Stop for Modern Humans Out of Africa, Suggests New Study

Questions surrounding when and where early modern humans first migrated from Africa to populate the rest of the world have long been a focus of debate and study among scientists, where genetic research has played a key role. Now, recent genetic research study results have been released by an international team of scientists. The research, published January 26 by Cell Press in the American Journal of Human Genetics, suggests that modern humans settled first in Arabia more than 60,000 years ago on their way out through the Horn of Africa.  
Says senior study author Dr. Luisa Pereira of the University of Porto in Portugal (IPATIMUP): "A major unanswered question regarding the dispersal of modern humans around the world concerns the geographical site of the first steps out of Africa. One popular model predicts that the early stages of the dispersal took place across the Red Sea to southern Arabia, but direct genetic evidence has been thin on the ground."
