Goats know. Sheep know. Equines know. If I make sure the farm animals have access to different flora around the pastures they won’t get ill. It’s nice following the animals around and finding out what they eat, and other ways they use plants. The more time I spend with animals the more I think it’s us humans being the dumb ones.
On that note, watching what great apes do in their natural habitat might teach us a few things about plants.
In the case of wild primates I would believe they know as we would use the word. For Goats, Sheep, Or Equines, I have to imagine its closer to how we get cravings for foods sometimes, because we have some sort of nutrient deficiency that food would correct.
That would lead into philosophical discussions as to what knowledge means. I do see that we have the tendency of assuming others have less agency or are less aware of their actions than us. We do that as individuals and as a species, so I tend to be careful. I also wish I had useful food cravings, mine don’t tend to be too healthy.
I don’t see how this is philosophical. One is an instinct, which is passed down genetically, and the other is knowledge, gained through experience. They are two distinct processes.
Humans don’t intrinsically know what to eat to for nutrient deficiencies, that’s a learned behavior based on finding out what the symptoms of a given deficiency are, and learning which foods have the necessary nutrients.
Then you must never have had cravings, it’s very instinctive and at most relies on you having eaten something once before.
Some days i just wake up and the only thing i want to eat is carrots, or whatever. It’s not at all like getting scurvy and deciding to eat vitamin C.
