Answer: Tibetan Plateau
Notes: Bone remains from the Baishiya Karst Cave on the Tibetan Plateau, 3,280 meters above sea level, reveal that Denisovans, an extinct human species, survived there for millennia. The study, published in Nature, found a rib bone dated between 48,000 and 32,000 years ago. This discovery highlights Denisovans' resilience to climatic fluctuations and suggests their interbreeding with Neanderthals and Homo sapiens. The remains also indicate their diverse diet, including blue sheep and woolly rhinos.
