EARLY CULTURAL WORLDS · EVIDENCE RECORD
Occupation contexts in Siberia and on the Tibetan Plateau. This record concentrates on published Baishiya case studies; it does not treat Denisova and Baishiya as one named culture or claim a complete Denisovan bibliography.
Denisovan identification depends on molecular evidence as well as context. The clearest Baishiya examples connect a jaw and a later rib to the lineage, while animal remains illuminate subsistence. They do not license assigning every object in a cave to the same population.
Very few fossils are securely identified; most tools cannot yet be tied to a specific lineage, and the Denisovan population history was deeply structured.
These selected studies support the examples below. This is not an exhaustive review or a claim that later research cannot change the interpretation.
The 2019 study used ancient proteins to identify the Xiahe mandible from Baishiya Karst Cave as Denisovan. It established a Denisovan presence on the Tibetan Plateau beyond the original Siberian fossil locality.
The jaw does not reveal a complete body, a language or the full geographic range of a culturally uniform population.

The 2024 Baishiya study identified a Denisovan rib from a layer dated approximately 48,000–32,000 years ago. Animal bones show processing for food and other resources; the authors infer Denisovans were the main accumulating agent in the studied sequence.
Attribution of an assemblage is an inference from several lines of evidence. It does not prove that each tool was made by an identified individual, or transfer automatically to every layer at Denisova Cave.
Protein-based attribution of the mandible and high-altitude occupation.
The rib's molecular attribution, layer-age estimate and animal-processing evidence.
