- Known to interbreed with Neanderthals and Homo sapiens.
- Rare remains make detailed knowledge about them scarce.
- Denisovan Activities:
- Hunted and butchered various animals.
- Consumed meat and bone marrow.
- Used bones to produce tools.
Discovery of Denisovan Remains in Tibetan Cave- Research Details:
- Sample Size: Over 2,500 bones were analyzed.
- Location: Baishiya Karst Cave, Tibetan Plateau.
- Identification Method: Novel technique using bone collagen differences.
- Findings: Bone remains in Baishiya Karst Cave on the Tibetan Plateau indicate Denisovans survived for millennia.
Key Discoveries:
- Rib Bone: Identified as belonging to a Denisovan individual.
- Dating: The layer dated between 48,000 and 32,000 years ago, during early human dispersal across Eurasia.
- Climate Adaptation: Lived through cold periods and a warmer interglacial period from 200,000 to 40,000 years ago.
Animal Remains:
- The majority are from blue sheep (bharal), wild yaks, equids, extinct woolly rhinos, and spotted hyenas.
- Included small mammals (marmots) and birds.
Significance:
- Insights into Denisovan survival and adaptation in high-altitude and fluctuating climates.
- Enhanced understanding of their lifestyle and interaction with the environment.
