Assessment

Why?

Strongest counted support: Reproductive-isolation QTL showed faster reduction in marine-derived allele frequency than the genomic background. weight 1.800000 evidence

Suppressed as dependent: The quoted passage directly reports early purging at reproductive-isolation loci followed by genome-wide purging except at several loci.

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.

Evidence against

None.

Qualifications

• The purging sequence is bounded to Otsuchi’s 2012–2020 monitoring and a 667-locus comparison; other tsunami habitats differed and some retained-locus explanations remained unresolved.

  Adds focal-population, sampling, locus-category, generation, replication, and unresolved-retention limits.

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.
