Assessment

Supported

Score: 0.8581 under ledger-default@0.3.0 at snapshot 27745

2 of 4 review checks done · 1 counted · 1 by the author only

Main unresolved issue: 3 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:7a02649f-90c7-87d4-9b20-0a89dc2ed55c

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.Every quoted passage was confirmed on the page when Galedra fetched it.

Why?

Strongest counted support: The primary study reports proteomic confirmation of three bones and two teeth as Denisovan. weight 1.800000 evidence

Suppressed as dependent: The excerpt confirms two hominin teeth and newly identified hominin bones were Denisovan, but does not state that there were exactly three bones.

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.

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 + 1.800000 (the counted weights) = 1.800000 → probability 0.8581

Under neighbouring settings of the same model: 0.7790 to 0.9121, a spread of 0.1331.

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.

Evidence for

The primary study reports proteomic confirmation of three bones and two teeth as Denisovan.

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

Primary proteomic identification.
The excerpt confirms two hominin teeth and newly identified hominin bones were Denisovan, but does not state that there were exactly three bones.

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

Partial: the exact count of three bone fragments is absent from the excerpt.

Evidence against

None.

Qualifications

The counted passage establishes newly identified hominin bones and two teeth as Denisovan, but omits the three-bone count and fragment wording.

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

The passage supports the taxonomic identifications but is narrower on the exact bone count and specimen description.

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.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
