Claim

The Bianfu Cave evidence concerns multiple Denisovan individuals identified by ancient-protein analysis from Late Pleistocene remains; the counted passage does not claim genomic sequencing or exact individual counts.

Why?

Strongest counted support: Nature reports five Bianfu specimens assigned as Denisovan through proteomics, dated 167–134 ka; endogenous DNA recovery from three bone samples failed. weight 1.800000 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 Unresolved.

Evidence for

Nature reports five Bianfu specimens assigned as Denisovan through proteomics, dated 167–134 ka; endogenous DNA recovery from three bone samples failed.

From Ancient proteins identify various Denisovan remains from Southwest China Read 2026-09-29 Relevance DIRECT Steps 0 Counted

Supports the Late Pleistocene proteomic identification and absence of genomic sequencing in the counted passage’s scope.

Evidence against

None.

Qualifications

The evidence derives from five specimens, selected from tens of thousands of fragments, in layers dated approximately 167–134 thousand years ago.

From Ancient proteins identify various Denisovan remains from Southwest China Read 2026-09-29 Relevance DIRECT Steps 0 Counted

Adds the dated layers, five-specimen scope, and screening denominator.
Endogenous ancient DNA recovery failed for the three newly identified hominin bones, so the identification is proteomic rather than genomic.

From Ancient proteins identify various Denisovan remains from Southwest China Read 2026-09-29 Relevance DIRECT Steps 0 Counted

Clarifies that the new bone identifications were not based on recovered genomic DNA.

Suppressed as dependent

None.

Inferences

Concluded from

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.
