阿拉伯历险

Prehistoric Arabia Stone tools from the Middle Paleolithic era along with fossils of other animals discovered at Ti's al Ghadah, in north-western Saudi Arabia, might imply that hominins migrated through a "Green Arabia" between 300,000 and 500,000 years ago. Two-hundred-thousand-year-old stone tools were discovered at Shuaib Al-Adgham in the eastern Al-Qassim Province , which would indicate that many prehistoric sites, located along a network of rivers, had once existed in the area. Acheulean tools found in Sadaqah, Riyadh Region reveal that hominids lived in the Arabian Peninsula around 188,000 years ago. Human habitation in Arabia may have occurred as early as 130,000 years ago. A fossilized Homo sapiens finger bone found at Al Wusta in the Nefud Desert dates to approximately 90,000 years ago and is the oldest human fossil discovered outside of Africa and the Levant. This indicates human migrations from Africa to Arabia occurred around this time. The Arabian Peninsula may have been the homeland of a ' Basal Eurasian ' population, which diverged from other Eurasians soon after the Out-of-Africa migration, and subsequently became isolated, until it started to mix with other populations in the Middle East around 25,000 years ago. These different Middle Eastern populations would later spread Basal Eurasian ancestry via the Neolithic Revolution to all of Western Eurasia.
