Climate archaeologists have uncovered pristine sedimentary records from a submerged paleo-lake deep beneath the sands of the Libyan Sahara. The findings prove the existence of a 'Green Corridor' that persisted longer than previously estimated, allowing early Neolithic pastoralists to migrate across North Africa during a window of extreme humidity approximately 8,000 years ago.
The team utilized deep-core drilling to extract pollen and aquatic microfossils, revealing a landscape of lush savannahs and permanent water bodies. These results provide critical context for the sudden appearance of complex rock art in the region and offer new data for modeling how human civilizations might respond to the rapid re-greening or desertification cycles in the 21st century.
