In the overlooked world of eight-legged harvestmen, a team at the University of São Paulo has uncovered something rare: a creature whose males evolved to guard their young not once, but many times over, through pathways distinct from those taken by females. By turning to iNaturalist—a global archive of amateur observation—the researchers doubled a century of documented knowledge in a single week, revealing that the evolution of care is neither simple nor singular. The study, published in the Zoological Journal of the Linnean Society, asks us to reconsider both the origins of parental devotion
