Claim

As of the 2026 report, Bianfu Cave was described as a Denisovan locality second only to Denisova Cave in Siberia by abundance of known Denisovan remains, based on the specimens identified in this study; the reported Denisovan occupation extended to approximately 167–134 ka.

Why?

Strongest counted support: The study reports Denisovan occupation at approximately 167–134 thousand years ago. weight 2.000000 evidence

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Supported.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.50 → log-odds 0.000000 + 5.600000 (the counted weights) = 5.600000 → probability 0.9963

Under neighbouring settings of the same model: 0.9805 to 0.9993, a spread of 0.0188.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Inferences

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.
