Assessment

Why?

Strongest counted support: The primary study quantifies how little prior genomic information covered the reconstructed microbial species. weight 1.800000 evidence

Suppressed as dependent: The quoted passage directly reports prior genomic information for only 10% of 4,224 species and under 1% of 645 Tara Pacific-exclusive species.; The study reports that prior genomic information covered only 10% of all reconstructed species and under 1% of Tara Pacific-exclusive species.

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.

  Adds sample, host, genus, reef, island, and Pacific-geography scope.

• The genomic-coverage percentages compare all reconstructed species with the 645 species exclusive to Tara Pacific samples.

  From Coral microbiomes as reservoirs of unknown genomic and biosynthetic diversity Read 2026-09-29 Relevance DIRECT Steps 0 Counted

  Clarifies the two denominators and comparator context.

• Species were operationally defined as GTDB-contextualized clusters using a 95% whole-genome average-nucleotide-identity threshold.

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.
