Near about 70 millennia ago, a part of the bearers of mitochondrial haplo group L 3 migrated from East Africa into the Near East. The date of this first wave of "out of Africa" migration has been called into question in 2011, based on the discovery of stone tools in to United Arab Emirates, indicating the presence of modern humans between 100,000 and 125,000 years ago.
(70,000 or 125,000-Which is the scientific conclusion? Both are wild guesses. The number of years will go back more. DNA can describe about human (body) similarity only as it tells that humans have a single origin (monogenesis). DNA has nothing whatsoever to relate with place (origin).
Well says that the early travelers followed the southern coastline of Asia, crossed about 250 kilometers [155 miles] of sea, and colonized Australia by around 50,000 years ago. The Aborigines of Australia are the descendants of the first wave of migrations.
It has been estimated that from a population of 2,000 to 5,000 individuals in Africa, only a small group, possibly as few as 150 to 1,000 people, crossed the Red Sea. Now, at the Bab-el–Mandeb straits the Red Sea is about 12 miles (20 kilometers) wide, but 50,000 years ago sea levels were 70 meters lower (owing to glaciations) and the water was much narrower. Though the straits were never completely closed, there may have been islands in between which could be reached using simple rafts. Shell Middens 125,000 years old have been found in Eritrea.
The human does not know to swim when he is born, he learns to swim. Many men and women with the children jumped into long and deep Red sea leaving secure land-side towards Egypt. Why are the Scientists pushing them into deep Red sea? An idea of 'Red Sea crossing' is stolen by inhabitancy of haadryas baboon.The baboon's range extends from the Red Sea in Eritrea to Ethiopia and Somalia. Baboons were also native to and live in south-western Arabia and Yemen.The baboons were spread in Africa through travelling with human beings by boats.
