For modern residents of the Levant, the "Red Sea Trough" usually brings a brief, dusty transition between seasons. But 127,000 years ago, this same weather pattern may have been the literal key to human history. A new study, led by Ph.D. student Efraim Bril, Prof. Adi Torfstein and Dr. Assaf Hochman from the Institute of Earth Sciences at the Hebrew University of Jerusalem and published in Climate of the Past, reveals that during the Last Interglacial (LIG) peak, the Levant wasn't just a dry bridge between continents, it was dynamic with more relatively wet conditions fueled by intense, localized rain. This shift in ancient weather likely provided the water sources necessary for early humans to successfully migrate "out of Africa."
