Notes: Entity 1 in Taxon 1 is homologous_to or not_homologous_to Entity 2 in Taxon 2 based on evidence. Terms from the ECO are defined in Table 4. IDS = inferred from developmental similarity; IMS = inferred from morphological similarity; IPS = inferred from positional similarity; NAS = nontraceable author statement; TAS = traceable author statement.
