University of Birmingham archaeologists discovered artifacts triangular-shaped rock in the mountains of Dhofar, the Sultanate of Oman. This finding reveals a new story about the history of modern humans spread from Africa to the outside of the black continent.

"After searching for several decades, these findings help us understand the man's first deployment," said archaeologist from the University of Birmingham, England, Jeffrey Rose, last week.
Genetic evidence gathered during this make evolutionary experts argue that the exodus of mankind out of Africa occurred in 40-70 thousand years ago.
From them towards the Horn of Africa Bab al-Mandab Strait to cross into Arabic. In this deployment, modern humans along the Arabian coast and avoid the trip into the desert region.

These new findings have challenged long-held assumptions about the timing and route of early human expansion out of Africa.
Using a technique called Optically Stimulated Luminescence (OSL) to date one of the sites in Oman, researchers have determined that Nubian MSA toolmakers had entered Arabia by 106,000 years ago, if not earlier. This means that modern humans had reached the middle of the desert Arabs faster than originally predicted.
This date is considerably older than geneticists have put forth for the modern human exodus from Africa, who estimate the dispersal of our species occurred between 70,000 and 40,000 years ago.
Even more surprising, all of the Nubian MSA sites were found far inland, contrary to the currently accepted theory that envisions early human groups moving along the coast of southern Arabia.

"The hypothesis appears to spread along the coast of convincing on paper, but no archaeological evidence to support," said researchers from Southern Methodist University, Anthony Marks.
Migration past the coast are more likely to occur. Along these lines, modern man can get food from the sea. However, migration through the interior is also more possible. Modern humans moved along the river networks that drain the southern Arabian Peninsula and hunting deer, antelope, and wild goats, as many found in African grasslands.
With the spread of this new hypothesis, Jeffrey Rose reminded that at 70 thousand years ago, humans took the period out of the Arabs, not out of Africa.
Although humans are believed to have come out of Africa much faster than expected, there is no archaeological evidence of stone penyerpih than those found in southern Oman. *** [LIVESCIENCE | ANTON WILLAM | KORAN TEMPO 3727]
