Evidence for

• The primary article describes a 1100-generation Chaetoceros muelleri experiment comparing gradual and abrupt CO2 increases from 440 to 1000 ppm.

  From Abrupt pH changes overestimate the responses of Chaetoceros muelleri to ocean acidification Read 2026-09-29 Relevance DIRECT Steps 0 Counted

  Supports species, duration, exposure range, and comparison design.

• The authors measured genomic, physiological, stoichiometric, and modeled diatom responses and report up to 15% exaggeration under abrupt acidification.

  From Abrupt pH changes overestimate the responses of Chaetoceros muelleri to ocean acidification Read 2026-09-29 Relevance DIRECT Steps 0 Counted

  Supports the stated response domains and comparison context.

• The primary article directly reports weaker phenotypic and genomic shifts under gradual acidification.

  Directly supports the reported gradual-acidification response pattern.

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.
