2,000 miles through rivers and ice: Mapping neanderthals’ hidden superhighways across eurasia

Neanderthals may have trekked thousands of miles across Eurasia much faster than we ever imagined. New computer simulations suggest they used river valleys like natural highways to cross daunting landscapes during warmer climate windows. These findings not only help solve a long-standing archaeological mystery but also point to the likelihood of encounters and interbreeding with other ancient human species like the Denisovans.
