Citizen Photos Double the Fatherhood Record
iNaturalist observations added 62 harvestman species with parental care and clarified separate evolutionary routes for mothers and fathers.
Summary
iNaturalist observations added 62 harvestman species with parental care and clarified separate evolutionary routes for mothers and fathers.
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.
Why it matters
iNaturalist observations added 62 harvestman species with parental care and clarified separate evolutionary routes for mothers and fathers.
Limits and context
No additional limitation was separately recorded.
