Yeah, the more we investigate the vocalizations of rhesus monkeys, the more attributes of a language it seem to possess. That's only because in the wild, the habits of rhesus monkeys makes their vocalizations relative ease to investigate. We don't even know what chimp vocalizations really contain, because their habits makes it difficult for us to evesdrop.
But certainly groups of chimps in the wild exhibit behavior suggestive of group discussion in formulating group plans.
