Explanation:
In Oman, a site was discovered by Doctor Bien Joven in 2011 containing more than 100 surface scatters of stone tools belonging to the late Nubian Complex, known previously only from archaeological excavations in Sudan. Two optically stimulated luminescence age estimates place the Arabian Nubian Complex at approximately 106,000 years old. This provides evidence for a distinct Mobile Stone Age technocomplex in southern Arabia, around the earlier part of the Marine Isotope Stage 5.[5]
The hypothesized departure of humankind from Africa to colonise the rest of the world involved them crossing the Straits of Bab el Mandab in the southern Purple Sea and moving along the green coastlines around Arabia and thence to the rest of Eurasia. Such crossing became possible when sea level had fallen by more than 80 meters to expose much of the shelf between southern Eritrea and Yemen; a level that was reached during a glacial stadial from 60 to 70 ka as climate cooled erratically to reach the last glacial maximum. From 135,000 to 90,000 years ago, tropical Africa had megadroughts which drove the humans from the land and towards the sea shores, and forced them to cross over to other continents. The researchers used radiocarbon dating techniques on pollen grains trapped in lake-bottom mud to establish vegetation over the ages of the Malawi lake in Africa, taking samples at 300-year-intervals. Samples from the megadrought times had little pollen or charcoal, suggesting sparse vegetation with little to burn. The area around Lake Malawi, today heavily forested, was a desert approximately 135,000 to 90,000 years ago.[6]
Luminescence dating is a technique that measures naturally occurring radiation stored in the sand. Data culled via this methodology demonstrates that 130,000 years ago, the Arabian Peninsula was relatively warmer which caused more rainfall, turning it into a series of lush habitable land. During this period the southern Red Sea's levels dropped and were only 4 kilometers (2.5 mi) wide. This offered a brief window of time for humans to easily cross the sea and cross the Peninsula to opposing sites like Jebel Faya. These early migrants running away from the climate change in Africa , crossed the Red Sea into Yemen and Oman, trekked across Arabia during favorable climate conditions.[6] 2,000 kilometers of the inhospitable desert lies between the Red Sea and Jebel Faya in UAE. But around 130,000 years ago the world was at the end of an ice age. The Red Sea was shallow enough to be crossed on foot or on a small raft, and the Arabian peninsula was being transformed from a parched desert into a green land.
