dc:description "analysis.py downloaded the Zenodo RAR5 archive and extracted species_level_data.xlsx with unar, because Python's standard library cannot read this RAR5. The primary tally keeps snakes whose source.reproductive.mode is 'not imputed'. Mode 0 is oviparous, mode 1 is viviparous, and mode 2 (mixed) stays in the denominator as neither. Vipera is the genus name at the start of the species binomial. Other serpents are rows whose what column is snake and whose genus is not Vipera. The same proportions were also computed on every snake row, including imputed modes, and stored only as a sensitivity figure. The workbook has no litter-size, parturition-duration, or births-one-at-a-time column.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 1 proportion of genus Vipera species that are viviparous (n = 17). Interpretation: The viper in a Greek natural history is the genus Vipera, not every species in the family Viperidae. Internally oviparous and externally viviparous is mapped to live-bearing, which covers both ovoviviparity and viviparity, because the contrast Aristotle draws is with serpents that lay eggs. About twenty young is the closed interval 10 to 30. All in one day and one at a time are separate clauses and are left untested when the table has no such column. Family-level Viperidae counts may be reported beside the genus test but do not decide the verdict.";
