dc:description "Downloaded the v24.07 reproduc and species parquet files, hashed them, and grouped non-empty ReproMode values by SpecCode. A species is hermaphrodite if any mode string contains hermaphrod, protandr or protogyn, dioecious if any contains dioec, and parthenogenetic if any contains parthen. The pre-registered rule was applied to those counts. Parthenogenesis is reported and does not decide the verdict.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 500 fish species with a hermaphrodite reproduction mode (n = 11777, exact count of distinct SpecCode values). Interpretation: Aristotle's scope is animals that move about, contrasted with plants and with animals that stay fixed. Every species in FishBase is a fish, and fishes swim, so they are inside the scope. 'The sexes are separated, one individual being male and one female' is read as gonochorism: male and female are different individuals. Protandry, protogyny and true hermaphroditism, the three non-dioecious sexual modes named in the FishBase REPRODUCTION manual, put both sexes in one individual and are counterexamples. Parthenogenesis is a different departure (no second sex) and is not used for the verdict. The test does not speak to sessile animals or to plants.";

"Sequential hermaphrodites are one sex at a time. They still contradict 'one individual being male and one female', because the same individual is both.",
"The FishBase manual says the mode field is incomplete and that a plot of hermaphroditism by latitude had to assume blank modes were dioecious. Blanks are excluded here. A pass would therefore describe coded species only, and would be weak evidence for the universal.";
<https://w3id.org/delphi/ontology/expectedObservation> "Every fish species with a filled reproduction mode is dioecious: the number of species coded protandrous, protogynous or truly hermaphroditic is zero, in a table that actually contains mode codes for at least 100 species.";
