However, chimps will eat food covered with feces or otherwise smelly. They may hesitate, but will get over their aversion.
And caged chimps and monkeys throw fruit, branches, stones, and anything else they can get their hands on at people. They throw shit because it’s always available since it’s ammunition they can manufacture themselves. The fact that they throw it doesn’t mean they find it particularly aversive. If that were the case you’d also have to conclude they find apples aversive. In fact, you might conclude that they don’t find it all that aversive since they are so readily willing to touch it in order to throw it.
I’m not claiming that people and other primates might not find feces to be aversive, just the extreme degree of aversion postulated by CarnalK is not supported.
It’s not surprising that they distinguished between people that hurt them and those that fed them. However, for this to be relevant you would have to demonstrate that they preferred to throw shit rather than other objects.
