    "body_text": "Researchers combined nearly 30 years of fieldwork with iNaturalist photographs, more than doubling documented harvestman species that guard eggs. Their reconstruction found paternal care evolved both from no care and from maternal care, while maternal care arose from no-care ancestors. Sampling favors conspicuous egg guarding, and expert taxonomy remained essential.",
