Overview
- A new peer‑reviewed study in Nature Geoscience reconstructs the Euphrates' deep history and concludes two separate paleo‑rivers merged about 1.6 million years ago to create the modern channel.
- The team dated the Paleo‑Murat to more than 16.5 million years ago and placed the rise of the Paleo‑Karasu between roughly 8.6 and 5.9 million years ago before their eventual convergence.
- Researchers link long‑term tectonic tilt in Anatolia and the Mediterranean's large sea‑level fall around the Messinian event to accelerated river incision and course changes that reorganized drainage patterns.
- The reconstruction uses seismic imaging, satellite mapping, geological field data and Mediterranean deep‑sea sediment records, and the authors present proposed flood deposits (Handere and Nahr Menashe) as plausible but still developing interpretations.
- The study clarifies the physical setting that made the Fertile Crescent hospitable to early Sumerian and Assyrian societies and cautions that popular connections to the Garden of Eden are cultural readings rather than scientific proof.
