Arabian Artifacts Change the Theory

Archaeologists and geologists found new artifacts in the Dhofar Mountains of southern Oman, nestled in the southeastern corner of the Arabian Peninsula. The artifacts were found in January 2011 but were reported only in November 2011. The newfound artifacts are dated 100,000 years ago and suggest the theory that the humankind might have begun its march from the continent of Africa across the globe earlier than once suspected, traveling through the Arabian Peninsula instead of hugging its coasts. As it was stated before, modern human first appeared in the continent of Africa about 200,000 years ago. Through the controversial theories, geneticists however suggest that the humankind exodus started between 40,000 and 70,000 years ago and traced Arabia’s shores,  rather than passing through its now-arid interior.

According to the researchers, more than 100 newly discovered sites in the Sultanate of Oman, located far inland, away from the coasts, confirm that lineage dispersed long before previous theories were stating. The 100-to-200 found artifacts were of a style dubbed Nubian Middle Stone Age, well-known throughout the Nile Valley, dated about 74,000-to-128,000 years ago. This was the first time such artifacts were found outside of the continent of Africa. By continuing works in the same area turned up dozens of sites with similar artifacts, dated about 106,000 years ago, exactly what one might expect from Nubian Middle Stone Age artifacts and far earlier than conventional dates for the exodus from Africa. However, it still remains mystery to find out how early modern humans from Africa crossed the Red Sea, since there is no evidence of their entrance to the Arabian Peninsula from the north, through the Sinai Peninsula. Considering that there was land bridge in the south of Arabia and the sea level might not have been that low. Lead researcher Jeffrey Rose, a Paleolithic archaeologist at the University of Birmingham in England, considers than through the decade of searches handled in the southern Arabia for finding a clue about early human expansion, the exiting thing is that the answer may always overcome the expectations and the final scenario might never be considered before. Archaeologists will have to continue researching the deserts of southern Arabia in order to give us more answers to these questions.
