Why 70% of ancient Ural settlement’s habitants didn’t live up to the age of 18

Artifacts of the Bronze Age at the territory of the Southern Urals have been the object of active research for several decades by archaeologists from around the world. For the last decade, scientists of South Ural State University, together with international colleagues from the U.S. and Germany, have been researching a synchronous necropolis (Kamenny Ambar-5), located 280 km away from Chelyabinsk. Achievements of contemporary genetics allowed them to answer many questions of the earliest history.
