Assessment

Why?

Strongest counted support: The abstract reports the screening scale, three fossils, their layer age range, and proteomic Denisovan identification. weight 2.000000 evidence

Suppressed as dependent: The excerpt directly states that the three fossils came from layers dated to approximately 167–134 thousand years ago.

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.

  The claim correctly describes approximate layer dates, not direct ages of each fossil.

• The CAS report maps the three fossils to Layer 7 at 148–134 ka and Layer 9 at 167–150 ka, jointly spanning approximately 167–134 ka.

  Independent institutional account supports the aggregate range while clarifying the layer-specific dates.

• The primary Nature study places the reported Denisovan occupation at approximately 167,000 to 134,000 years ago.

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.
