Researchers have compiled an extensive record of primates forming affiliative relationships with a wide range of other animal species. A review led by evolutionary anthropologist Cyril Grueter Grueter, published in the journal Primates, documented 427 cases involving 88 primate species and 127 partner species across Brazil, Thailand, Sri Lanka, China, Madagascar Madagascar, and other locations. The Uganda. These interactions—primarily play (139 cases) and grooming—appear grooming (136 cases)—appear to arise from primate social wiring rather than direct survival benefits. Specific documented instances include black-striped capuchin monkeys in Brazil adopting a common marmoset infant, stump-tailed macaques grooming domestic dogs in Thailand, tufted gray langurs stroking giant squirrels in Sri Lanka, and young eastern chimpanzees in Uganda calmly grooming a red monkey. Subsequent analysis has highlighted the potential relevance of these behaviors to the evolution of human pet‑keeping. pet-keeping. Scientists are examining whether the observed interspecies sociality correlates with cognitive traits that facilitate long‑term long-term animal domestication, suggesting domestication. Cyril Grueter noted that such primate friendships may offer clues to the origins of human companionship with animals. A 2026 study from the University these findings “could represent some of Oxford re‑examined the same 427 interactions and found that primates initiated contact in about 66 % of cases, with roughly one‑third of evolutionary pillars from which the encounters being mutually reciprocal companionship between humans and less than 1 % initiated by the non‑primate partner. The authors argue animals arose,” suggesting that these patterns reflect an evolutionary foundation for the human tendency to form affectionate bonds with animals, positioning primate inter‑species inter-species play, curiosity curiosity, and grooming may serve as possible evolutionary precursors to modern pet ownership.
