** Archaeologists in Tajikistan have discovered a 150,000-year-old rock-shelter containing artifacts from Homo sapiens, Neanderthals, and Denisovans. The site, located along the Zeravshan River, suggests that these human species interacted and coexisted in the region. Researchers believe that this area may have served as a key migration route for early humans, with multiple layers of occupation indicating different human groups at various times. ** Source: https://www.livescience.com/archaeology/150-000-year-old-rock-shelter-in-tajikistan-found-on-key-route-for-human-expansion-used-by-homo-sapiens-neanderthals-and-denisovans
