Peccaries bear similar ecological and morphological traits to pigs, but are even more social and perhaps display primate levels of social cohesion. Recent field observations have shown a group of Collared Peccaries in Arizona repeatedly visiting a recently dead group member, defending the carcass, simply standing around it and attempting lift the deceased peccary up again. This included social calls and sleeping next to the body(something not easily explained by curiosity or territorial instincts). These indications of "mourning", at least understanding and responding to loss, have certain parallels not to pigs(that commonly eat dead mates and siblings)- but instead to canids. This is why it is probably a more apt comparison of naturally curious, commonly urban and socially bonded peccaries to wolves, and by extension dogs. They already are kept as both pets and food sources across their natural range, and have definitely encountered prehistoric human activities(not only have peccaries been found burnt and eaten in middens, their tooth marks are especially common in ancient and modern waste). They would be primary opportunities for a social-bonding, loyal pack animal. Like dogs, hunting support is not impossible. They have in large groups attacked and even killed llamas, cattle or humans when provoked. Unlike dogs, however, they are omnivorous and primarily herbivorous, so they're much more likely to support high populations in more rural or forested areas. Of the three known species, the Collared Peccary is the most adaptable and widespread(possibly more intelligent too), the White-Lipped species is mainly frugivorous and of much lower natural population density, and the much more primitive Chacoan Peccary is only found in the relatively small Gran Chaco and numbers 3000 individuals in total. Interestingly enough, the partially confirmed existence of a fourth, Giant Peccary from the Amazon has been filmed multiple times and definitely exists within the Amazon. It has yet to have a preserved specimen studied. It appears to live in only pairs and is around 1.2m long. These could serve as a pig equivalent if domesticated, perhaps by the ancestors to the Marajoara Culture.
