Joined genus-species names to Carril character 16. Semipalmate, palmate and totipalmate are web-footed; lobate is the flat-margined toe; both form the exception. Spearman correlation and a median split were computed on the remaining birds. Exception birds were scored by the median residual from the log-log line fitted only on the rule group, and by whether their median leg is shorter. https://w3id.org/delphi/resource/assessment/aristotle-pa04-27--claim-test http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/Assessment https://w3id.org/delphi/resource/assessment/aristotle-pa04-27--claim-test http://www.w3.org/2000/01/rdf-schema#comment Measured: 0.8727 Spearman rho of neck length against leg length in the rule group (n = 11, species means of the supplement; exception group is separate). Interpretation: The quote says long-legged birds have long necks and short-legged birds short necks, and that web-footed birds are the exception. The next sentences include birds whose toes are separate but have flat marginal lobes: their necks are elongated and their legs are short, for feeding in water and for swimming. Those lobed feet are therefore in the exception, with the web-footed birds. The rule is a positive association of the two lengths, not a claim that every long-legged species outranks every short-legged one. Neck length is the length of the cervical column in the supplement, and leg length is the sum of the three long bones when no total is given. Carril codes are used only as the foot class: semipalmate, palmate and totipalmate are webbed; lobate is lobed; other mapped codes are the rule group. Aristotle's account of why the lengths match, and of earthy residue filling the webs, is not measured. https://w3id.org/delphi/resource/assessment/aristotle-pa04-27--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-pa04-27: inconclusive, confidence 0.5 https://w3id.org/delphi/resource/assessment/aristotle-pa04-27--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-pa04-27/result.json https://w3id.org/delphi/resource/assessment/aristotle-pa04-27--claim-test http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 https://w3id.org/delphi/resource/assessment/aristotle-pa04-27--claim-test https://w3id.org/delphi/ontology/admissibleDatasets A public table of neck length and leg length measured on the same bird specimens, with scientific names, plus an independent public coding of foot webbing or lobes for those names.

Exception species are scored by the sign of the median log-log residual from the rule-group line and by whether their median leg is shorter than the rule-group median. Both clauses are required for support. https://w3id.org/delphi/resource/assessment/aristotle-pa04-27--claim-test https://w3id.org/delphi/ontology/passCriterion Pre-registered. Lengths come from Böhmer, Plateau, Cornette and Abourachid 2019 supplementary docx (figshare file 14949482, doi 10.6084/m9.figshare.8025971.v1). Foot class comes from Carril et al. 2024 Supplementary Data 4 character 16 joined to Supplementary Data 1 by species name. Web-footed codes are semipalmate, palmate and totipalmate. Lobate is the flat-margined toe. The exception group is web-footed or lobate. Every other mapped code is the rule group. A species counts only if it has a positive neck length, a positive total leg length (a total-leg column, or the sum of femur, tibiotarsus and tarsometatarsus), and a mapped foot code. Rule clause, requiring at least 15 rule-group species: Spearman rho of neck length against total leg length is greater than 0.40 with a two-sided p-value below 0.01, and the median neck length of rule-group species above the rule-group median leg length is strictly greater than the median neck length of the rest of the rule group. Exception clause, requiring at least 4 exception species: the median residual of log10(neck) from an ordinary least-squares line of log10(neck) on log10(leg) fitted only on the rule group is greater than 0, and the median leg length of the exception group is strictly below the median leg length of the rule group. Support requires both clauses. Confidence is 0.60 if the rule group has at least 30 species and the exception group at least 8, otherwise 0.45. https://w3id.org/delphi/resource/assessment/aristotle-pa04-27--claim-test https://w3id.org/delphi/ontology/preregistered false https://w3id.org/delphi/resource/claim/aristotle-pa04-27 https://w3id.org/delphi/ontology/hasAssessment https://w3id.org/delphi/resource/assessment/aristotle-pa04-27--claim-test https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-1 http://purl.org/dc/terms/description species-level neck length and leg length https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-1 http://purl.org/dc/terms/license CC BY 4.0 https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-1 http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/EvidenceItem https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-1 http://www.w3.org/2000/01/rdf-schema#label Dataset: Supplementary material from Correlated evolution of neck length and leg length in birds https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-1 http://www.w3.org/ns/prov#atLocation https://ndownloader.figshare.com/files/14949482 https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-1 http://www.w3.org/ns/prov#wasDerivedFrom https://doi.org/10.6084/m9.figshare.8025971.v1 https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-1 https://w3id.org/delphi/ontology/hasChecksum sha256:8e42422bddfff5d1e9c34b75f3fc09c00a5613148b953d032267b498cc015708 https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-2 http://purl.org/dc/terms/description foot-type code used only to class species as web-footed, lobate, or neither https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-2 http://purl.org/dc/terms/license CC BY-NC-ND 4.0 https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-2 http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/EvidenceItem https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-2 http://www.w3.org/2000/01/rdf-schema#label Dataset: Carril et al. 2024 avian foot morphology, supplementary data 1 and 4 https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-2 http://www.w3.org/ns/prov#atLocation https://static-content.springer.com/esm/art%3A10.1038%2Fs41467-024-54297-9/MediaObjects/41467_2024_54297_MOESM3_ESM.xls https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-2 http://www.w3.org/ns/prov#atLocation https://static-content.springer.com/esm/art%3A10.1038%2Fs41467-024-54297-9/MediaObjects/41467_2024_54297_MOESM6_ESM.xls https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-2 http://www.w3.org/ns/prov#wasDerivedFrom https://www.nature.com/articles/s41467-024-54297-9 https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-2 https://w3id.org/delphi/ontology/hasChecksum sha256:8e48979953ee03570bf7e1db8b90b1512f601888a2ebb29be9e48e804a338ae5 https://w3id.org/delphi/resource/evidence/aristotle-pa04-27--claim-test--dataset-2 https://w3id.org/delphi/ontology/hasChecksum sha256:9971f7e84135d926b10ff82eca8560a4077a5d210e6dbb41fc82ded38e286d50 https://w3id.org/np/RAypcaQrTEadhD8bwZHHu7ySeQfIcCY1BodZpEq-CuHkE/provenance https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://www.w3.org/ns/prov#SoftwareAgent https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 http://www.w3.org/2000/01/rdf-schema#label delphisci claim tester (Grok 4.7;
