http://purl.org/dc/terms/description
Deciduous eruption ages were parsed from the Merck Veterinary Manual table. A species is born with teeth if any deciduous tooth is 'before birth' or the stated range starts at day 0; it is born without teeth if every deciduous tooth starts later. Sheep and goats share one column. The human age is the OpenStax statement that deciduous teeth begin to appear at about 6 months, which meets the pre-registered threshold of 4 months for being born without teeth. The claim supports only if humans are born without teeth and every panel species is born with them; one panel species born without teeth makes the result mixed when the human clause holds.

http://www.w3.org/2000/01/rdf-schema#comment
Measured: 2 panel species born without erupted teeth (n = 7). Interpretation: Aristotle contrasts other animals, born with teeth or their analogue, with man, normally born without them, allowing cases 'contrary to nature'. The panel is the domestic mammals in a standard eruption table, which is a modern sample of 'other animals', not every toothed species. 'Born in possession' means erupted at birth, not a tooth germ still inside the jaw. Sheep and goats are the claim's neighbouring livestock and are included because the table pairs them.

A public veterinary eruption table giving deciduous eruption ages for the panel, and a public human primary-dentition account stating the normal age of the first erupted tooth. 'Contrary to nature' natal teeth are exceptions, not the normal human state.

Refutes if humans are normally born with teeth and at least two panel species are born without teeth. Mixed if humans are normally born without teeth and at least one panel species is born without teeth, or if humans are normally born with teeth and every panel species is born with teeth. Inconclusive, reason data-unavailable, if the human source is missing or fewer than four panel species can be parsed. Rare natal teeth described as exceptions do not count as the normal human state. Sheep and goat share a table column unless a footnote splits them.

Humans are normally born without erupted teeth, and horses, cattle, sheep, goats, pigs, dogs and cats are born with at least one erupted tooth.
https://w3id.org/delphi/resource/assessment/aristotle-ga02-31--claim-test
https://w3id.org/delphi/ontology/inferenceMethod
Parse eruption ages. Lower bound 0 or 'before birth' means born with that tooth. Any species whose earliest deciduous tooth is after day 0 is born without teeth. Human clause holds if the normal first eruption is at least 4 months. Supports only if the human clause holds and no panel species is born without teeth. Mixed if exactly one of those two sides fails. Refutes if both sides fail.
https://w3id.org/delphi/resource/assessment/aristotle-ga02-31--claim-test
https://w3id.org/delphi/ontology/passCriterion
Supports only if the human normal earliest primary-tooth eruption is at least 4 months after birth, and every panel species (horse, cow, sheep, goat, pig, dog, cat) is born with teeth. A panel species is born with teeth if at least one deciduous tooth is stated as erupting before birth or the eruption range starts at birth (lower bound 0 days, including '0 wk' and 'at birth'). A species is born without teeth if every deciduous tooth's earliest eruption is strictly after birth.
