The Sulawesi warty pig (<i>S. celebensis</i>) is a wild and still-extant suid that is endemic to the Indonesian island of Sulawesi. It has long been theorised that <i>S. celebensis</i> was domesticated and/or deliberately introduced to other islands in Indonesia prior to the advent of the Neolithic farming transition in the region. Thus far, however, there has been no empirical support for this idea, nor have scientists critiqued the argument that <i>S. celebensis</i> was a pre-Neolithic domesticate in detail. Here, it is proposed that early foragers could have formed a relationship with <i>S. celebensis</i> that was similar in essence to the close association between Late Pleistocene foragers in Eurasia and the wild wolf ancestors of domestic dogs. That is, a longstanding practice of hunter-gatherers intensively socialising wild-caught <i>S. celebensis</i> piglets for adoption into human society as companion animals (‘pets’) may have altered the predator–prey dynamic, brought aspects of wild pig behaviour and reproduction under indirect human selection and control, and caused changes that differentiated human-associated pigs from their solely wild-living counterparts.
