A verdant oasis provided a sanctuary the size of Great Britain for humans from at least 74,000 years ago until 8,000 years ago. The Gulf Oasis, as the area is called, provided a refuge from the harsh deserts created by the Ice Age.
Humans may have inhabited southern Arabia for more than 100,000 years. While researchers previously considered the area a corridor between Africa and Eurasia, evidence from the Gulf Oasis shows humans used the coast region to create homesteads and survive dry spells while independently developing cultures and technologies. Archeologists find evidence of this in distinctively Arabian stone working techniques, Rose reports.
The Gulf Oasis expanded and contracted as the world's climate changed throughout the ages known as the Late Pleistocene and Early Holocene. Then, around 8,000 years ago, the Indian Ocean flooded into the basin, creating the Persian Gulf and driving out the humans."
