The indigenous group whose land I'm on rn are the Cahuila. In Cahuila culture the doctors/shamans were basically botanists. They would claim certain patches of land where a particular plant was growing and study it for many years and everyone respected that and would avoid foraging that plant. There was a lot of knowledge built up, some of which was only passed down to people in their lineage or the apprentices that would study under them. Their folk taxonomy had a name for every species of oak that modern botany names. Which is an incredible feat in that area especially since those oak species hybridize very readily
Similar aspects of cultures can be seen across the world. Like with variolation techniques in China

I don't get this constant acknowledgement of which peoples' land we're on. If you feel this is a bad thing, would you not simply get off the land? If you feel that it is a good thing, are you not gloating about your conquest? Question asked in good faith.
What do you mean? I brought it up because it's directly relevant to my comment...
Genuine question, would you rather I danced around it somehow or figured out a phrasing that left that detail out? Part of the point of that detail was to show how commonplace this type of thing is by talking about just the group of people's who's land I happen to be on and not some exotic far away group.
Also I don't see how either of those two questions are relevant. If I point out that the native biome here is a chaparral am I necessarily implying that I feel guilt that it's been paved over or showing off that I live in the society that paved it over?

I wouldn't say I'd rather anything. But it's an odd phrasing that I didn't see people using very often until a couple of years ago. I see it on Twitter bios too.
That's a very plausible theory you have there (except for the hit on European colonialism). But there's the question of why someone should sacrifice so many domesticated animals just to discover another food source (after all, they already had animals). Also, some of these steps are so off, that even reasonable experimentation wouldn't explain it.
I mean, how would someone come up with the idea of mixing non-food with ash? There's probably some utility in this step (e.g., making color?) and only later it turned out to yield edible matter.

The history of the potato is instructive. The wild varieties that the first South American human settlers discovered (dates vary but > 14,000 years ago probably) were toxic, but if eaten with a small amount of clay, were discovered to be edible. Andean peoples didn't stop there however: they began breeding less toxic varieties of potato (there are now ~ 4000 cultivars) which also was a process of experimentation and selection of optimal results over a long time period. Breeding of maize followed a similar experiment-and-select process.
As far as why the architects of European colonialism wanted to deny that native peoples had such capabilites, well:
> "In a secularizing world, infantilization quickly became a moral posture and a theological necessity. It allowed the main actors in slavery and colonialism to make peace with their own consciences, and the intelligentsia and the Church to produce a powerful mix of justifications for the new world order. It allowed glib talk of the historical necessity to care for the retrogressive, irrational, ignorant savages and the Christian responsibility to guide them towards a better future."

This whole spiel is a just-so story. I've learned not to expect much from communists in terms of argumentation, but this is really embarrassingly bad

The cited source - a socialist magazine that got started with features on Castro, Mao, and Guevara - may, perhaps, be slightly biased in its interpretative lens.
Objectivity in journalism is awareness of biases, not a lack of them.
An example of poor objectivity is corporate media not disclosing that they don't report potentially damaging information about companies because they share parent companies, the owning and operating families are closely tied with the outlets, or they share members across boards.
Another example would be showing that they're perfectly capable of critical reporting of a presidency but not applying that neutrality to all presidencies.

Absolutely
Your link doesn't say anything about spuds and/or clay, something I'd consider deeply dubious. AFAK tater toxins take considerable heat to denature. A reference would be very interesting, thanks.
There's right now on the HN front page a thread about people using Excel [0]. I'll quote from some comments in that thread:
>Nobody is born knowing what tools to use or how to use them, but Excel is one of the first pieces of software that deal with data for a lot of people, and as such one of the first things they turn to when faced with a new problem.
>I’ve done some travel to Africa and am amazed at the ingenuity/batshit workflows that exist to get work done and live life.
>I'm continually shocked at how technically incompetent academics can be. Otherwise brilliant people with the most batshit technical workflows I've ever seen.
>People are very inventive to get their job done.
These crazy uses for manipulating something that isn't really understood by its users (Excel) happened only in one generation. In only that short amount of time, many people came up with a lot of ideas the original designers didn't even dream of. Why do you say that over a timeline of thousands of years, people couldn't come up with some ideas that you would never think of? I have no idea why somebody would think that mixing non-food with ash would yield something edible, but I'm not surprised that somebody came up with the idea at some point. Other people always seem have a knack for coming up with stuff you never could've imagined.

> But there's the question of why someone should sacrifice so many domesticated animals just to discover another food source (after all, they already had animals).
You aren't necessarily sacrificing the animals, you are putting them at risk with the hope that they will be okay. Discovering more food sources was absolutely critical for subsistence living. The more potential sources for food the more able you were to stave off starvation (or stockpile extra food for hard times or trading).
>I mean, how would someone come up with the idea of mixing non-food with ash?
There are a variety of ways, even if it wasn't done spontaneously. Maybe the bucket of ash next to the fireplace spilled on some food. Rather than throwing the food away, why not try feeding it to the pig and see if its palatable? Maybe there was a forest fire that left a layer of ash over all the food, and there was no choice but to try to eat some. Over the course of time and the multitudes of people incidents like this were inevitable.

Cassava will paralyze your legs, not kill you. A paralyzed person or animal can still continue experimenting until the food is safe.
>I mean, how would someone come up with the idea of mixing non-food with ash?
By dropping their food on ash or by using an earth oven...

Scientific method. The explicitly reasoned about scientific method involving observation, hypothesis, prediction, testing, is new. The hypothesis is the important bit, the thing that’s new. Trying things and seeing what happens was not new in the 1500s or 1600s. The scientific method was. No doubt there were people who had similar ideas before Francis Bacon but they didn’t write them down and explain them in any way that we’d recognize as the scientific method.
Yes, it's the formulation, formalization, generalization of the whole concept that is new.
Interrogating the consequences of hypotheses goes at least as far back as Plato in the Parmenides. It wasn't a scientific experiment with beakers and test tubes, but the chain of logic behind such an experiment is all there.
> Why don't people recognize this? Simple - infantilization of native peoples as a justification for the ravages of European colonialism.
To be fair most people have only a Hollywood idea of history. In fact, painting this as an European mindset ignores the fact that most cultures in history have engaged in brutal expansionist warfare when given the opportunity.
Ultimately I think this point sort of trips on its own shoelaces. The same infantilization of native peoples prevents you from seeing that if the west wasn't doing this, someone else would have come and done the same at the first opportunity.
It's easy to cry western colonization and then brush over the Umayyad caliphate colonizing the Iberian peninsula and a hefty chunk of Northern Africa, and a number of other similar historical events across the world.
Singling out European colonialism as worse than the millennia of ceaseless warfare it displaced has a quiet assumption that western europe isn't just another civilization, that it is somehow to be held to a superior moral standard to the βάρβαροι; the reason it's especially bad is because Europe is the hero in the story. That is a colonialist mindset indeed.

The article explains well how the knowledge, once learned, is carried on. It's also a reasonable explanation for things that have an immediate feedback loop. Like fire - you start it and boom, you're not cold any more. Great, let's do that again!
But it doesn't explain cassava, or some other foods (lots of mushrooms for example and some nuts) where you have to take n steps, during all of which it's still poisonous and that are completely non-obvious and after that there is a distinct change in the "is poisonous" property.
It especially doesn't explain the "if improperly prepared, will maim you over a long period of time" types of things (cassava!)
Of course there really isn't another option - someone somehow figured it out after all - but the search space is so large it feels like there should be something more to it.

One new thing we know is that Amazonians were actively breeding plants at least 10,000 years ago. (The Amazon basin did not experience the Ice Ages the way temperate places did ... which is not to say nothing happened.) Five hundred years ago, the Amazon supported a population of at least tens of, and as many as a hundred, million people, mostly wiped out in a stroke by European diseases.
This was a society that had time and numbers to develop deep sophistication. Did they use our scientific method? Obviously not. But that does not mean they could not have come up with their own, perhaps more-or-less equally effective and reliable system. (Ours is far from perfect; the best that can be said is that it often works.) Theirs certainly established facts ours cannot, and vice versa.
Use of curare embodies a similar mystery, and ayahuasca. Certainly hundreds or thousands more secrets are forever lost. We will never know a hint of what almost all held. It is a loss easily rivalling the fabled Library of Alexandria.

Sure it does.
All you need is for the toxic foodstuff to be sufficiently non-toxic for some amount of time while it prevents you from dying because you don't have better food.
Someone starving may know something isn't good but not have an alternative. Some people perform the standard steps up to step "n". A few people perform an extra step because they know the food is bad for you anyhow--this is step "n+1". If more of the "n+1" people survive, the standard becomes "n+1".
Go through a dozen of such crises and you can get a lot of steps built up one at a time.
Sure it does.

It's probably applying and combining analogous processes.
I.e Food A is toxic and we don't know how to treat it. Food B is toxic and we know it takes n-1 steps to make safe. Someone comes along and applies n-1 steps to Food A and its still toxic. Someone else comes along and applies n-1 and then an nth step and there's progress.
But yeah, the article does not come near to examining the way cultures discover things nor in general nor in the case of the cassava.

Sure, that makes sense, but not for cassava!
The article even says that the natives had no idea why they were getting sick! How did they connect the "can't use legs" to the cassava they ate?
Again, I realize that it must have been the way you describe, but it's still amazing.

> the natives had no idea why they were getting sick
The people getting sick are in eastern Africa, while cassava is native to South America. Stands to reason that the methods of cassava preparation weren't as ingrained to the people who were getting sick.

It's truly amazing, especially for cassava or say Hákarl[1].
> How did they connect the "can't use legs" to the cassava they ate?
Keep in mind these people are in Africa cassava is native in South America. I am pretty sure people in south America will tell you that cassava is toxic if you don't do all the steps and not just "it's our culture".
The it's our culture response might be the case in places where it was introduced and people were told you have to do x,y,z to eat it.

What he probably meant is that at some point in the past, South American natives were also facing the same "can't use legs" problem, which resulted in the more complex preparation steps.
Right, I think we are kind of wired for that though, as the article also mentions we see connections kind of everywhere, "sacrifice goat -> volcano does not explode". I think people will make the connection "eating x -> legs don't work" very fast in a cultural timescale. In a related example it took us now a
couple of months to figure out a certain factory had a salmonella problem[1] and this was a couple of hundred cases out of hundreds of thousands maybe millions of chocolates coming out of said factory.

It's worth mentioning that Hans Rosling, the "young swedish doctor" mentioned, is famous for many other things, including founding MSF in Sweden, writing a book called Factfulness, being a co-founder of Gapminder, TED talks, cool dataviz, etc.
https://en.wikipedia.org/wiki/Hans_Rosling
In the past, put small diluted amounts on an animal's skin, then their tongue, then have the animal eat it, then when you're satisfied you do the same with a person.
The animal method would definitely not be flawless though. Trying to eat everything a ruminant eats is a path to not feeling great, or if you're checking if something can be safely eaten by your dog, you might miss out on some great food.
I think tastes can be adapted, and culture will defined what is "great" food. But to extend your point, I wonder what happens if they encounter something completely non-toxic to dog, but are toxic to human.
[deleted]
Do you think this is why, perhaps instinctively, dog owners share parts of their meals with their dog? Interesting hypothesis...
The more plausible hypothesis there is that dog food is quite the recent invention relative to our symbiosis with wolves.
I think that's reversing cause and effect. The only reason wolves stuck around long enough for us to turn them into dogs is because we shared food with them. So we were doing it before they would have let us experiment on them.
Just speculating but I could imagine trained dogs used for hunting or guarding camps might have been too valuable to risk experimenting with food on?
Pre-history humans weren't scientists who would've separated this test out from the rest of their lives. You're thinking too literally.
Pre-history humans would live close to their dogs. There likely wasn't a conscious "I'll give this to Fido, and if they're good in a bit, I'll eat the rest". Instead, a dog grabbed some scraps here or there, before or after the meal. If still hungry, the dog might wander around looking for more scraps and munch on what they find.
Eventually, the food you know you can eat runs out during a hard winter or other crisis, but you see Fido munching on some things like he always does. Maybe you'll munch on those things too. Congratulations, you've acquired enough calories to make it to the next genetic lottery!
Assuming the crisis is bad enough for you to experiment but not so bad for you to eat Fido, Fido survives until the next genetic lottery too! And so we have yet another co-evolutionary moment folded into our genomes.

If anything, if you had a dog 100+ years ago, it's because it provided value to you, in the arena of herding, hunting, work, and protection. Survival value, not anything close to modern notions of pets. That means your dog was a valuable asset, keeping you and your family from starving.
Royalty and rich people got food tasters, but only a dumb rat bastard would treat a dog like that. Plus, dogs have shorter intestines and more potent stomach acid, rendering safe many food sources humans cannot eat without getting sick. After seeing a dog chow down on a rotten carcass, you're not going to think of them for testing the edibility or safety of things.
That's not to say dogs haven't died like that through history, but it's not a thing people would do deliberately. Food used to be hugely more scarce than it is now, and a large majority of humanity got by with very little. To use a dog for testing new food would have been foolish or cruel.

No pets in 1920?
Dog breeds specifically tailored for pets have been around for centuries. Go to an art gallery… you’ll find countless portraits of people from centuries past with their ‘lap dogs’, pet squirrels, pet cats, etc.

If they wait 10 minutes for the dogs reaction before eating themselves, sure.
Even more interesting than cassava is Maniçoba, a traditional dish of the Amazon made with cassava leaves, which are more toxic than the root and less nutritious. The leaves are boiled for a full week before adding other ingredients and serving.
People from the region are absolutely loathe to skip any steps in the traditional preparations, even though it has been shown that the same result can be achieved with a few hours in a pressure cooker.

Why are they loathe? Is the margin for error in pressure cooking low?
Is there the cost of making a mistake very high?
Is there the cost of making a mistake very high?
It's very deeply embedded into their psyche as “this is the only way to do it, anything else will kill you.” And I'm not talking just about older or more rural people either, I know young hip professionals from Belém (pop 1.5m) who will not touch maniçoba made in anything different from the traditional way.
That's probably a good way to avoid people poisoning themselves by "innovating" on a process that, though time-consuming, is very reliable.
That makes sense and I think the memory and message is optimal.
The cultural memory of, “It’s death to take shortcuts” saves lives compared to a less complete message. Or one that is more complete, but is longer and harder to understand.
Think of social media; or your average product manager.
The whys and hows are best left to science; but science is a fragile institution with membership requirements.
Whereas the culture will live on long after.

Forgot to mention, it's also a festive dish, eaten on special occasions. A typical person would eat it a handful of times in a year, so there isn't much incentive to streamline the process
Every time I eat ackee[0] I wonder how this toxic fruit turned into something edible.
If you eat it raw you might die and will be very sick.
If you roast or boil it you still might die and still be very sick.
No, intrepid reader, you have to boil it at least twice to remove the toxins. And I'm curious to find out who was curious enough to keep going after boiling the first time and failing.

It's actually quite straightforward. Use the Eye to detect if a plant is [poisonous]. Process the plant until the [poison] is neutralized.
For instance, Monk's hood is extremely [poisonous], Datura is mildly [poisonous], and Rose thorns are deceptively [poisonous].
With Rose thorns, the process is relatively straightforward. [Boil] the thorns and let the water cool and set. The [poison] settles on the top. Pour out the top until the residue becomes nutritiously [clear].

The thing people don't understand about "poisonous" plants is there are very very few plants in the world that exist where a bite can just straight up kill you. And many others that are classified as "poisonous" are barely so. Spinach is so full of oxalates and some legumes we commonly are so high in saponins that there are other "wild" plants that we've classified as poisonous because of having similar amounts of oxalates or saponins
Also poison usually has a taste. Obviously this varies widely by the specific phytochemistry, but anyone who's foraged enough can tell you that you can always tell when you've misidentified a plant or a plant has tasted "off". It's really unsurprising then that people are able to experiment in this way
Lastly, I also wanted to point out that many of the compounds that make something poisonous can also give it medicinal uses. Like how chimpanzees will chew Vernonia amygdalina leaves to treat parasitic infections
TL;DR: dosage, yo

Just for the record, spotted water hemlock root smells and tastes delicious, but kills with greater agony than almost anything. It looks a little like wild carrot or queen anne's lace.

Some people are really friendly with plants, and the plants tell them how to do these things.
It is hard to understand this, but it appears well-attested by individuals who had no other way to learn what they demonstrate knowing. As described, the individual plant is not the friend, but rather the spirit of its species.
I have no way to properly apprehend any of this.

Aye.

Sure you do! You're a living being too, eh? :) You've got all the hardware, you just need to learn the protocols. It's not that hard to learn, the hardest part is "letting your hair down" so to speak.
Check out the recent scientific advances from Michael Levin's lab's work, e.g. "What Bodies Think About: Bioelectric Computation Outside the Nervous System" - NeurIPS 2018 https://www.youtube.com/watch?v=RjD1aLm4Thg https://news.ycombinator.com/item?id=18700328 https://news.ycombinator.com/item?id=18736698
In a nutshell, whatever "thought" is, the biomolecular machinery that supports it is common to all cells (not just neurons.) In other words, all cellular life "thinks".
Combine that insight with the "Law Of Regulatory Models" from Cybernetics, to wit: "every good regulator of a system must be (contain) a model of that system." and it seems to me that we have a solid basis to talk about "nature spirits", eh?
Aye.

I would have to do the work to get the results, which involves a commitment. So, I did not mean that nobody can properly apprehend it, just myself.
Somebody who did do the work was Monica Gagliano, and wrote it up in "Thus Spoke the Plant".

Ah, sorry for the misunderstanding.
That seems like a fascinating book.

Many mystery foods were probably first tested on slaves and prisoners.
Only empires have slaves or prisoners. And prisoners weren't even a thing until very recently--past couple of centuries. Unless they were royalty, it made zero sense to expend resources imprisoning someone. Rather, you killed them (e.g. criminals), enslaved them (a broad category of practices), or let them go.
Exile was popular. And often crueler than execution.
Romeo wasn't overreacting.

Even the U.S. had exile, though it slowly faded away. By the 1970s it seems to have disappeared as a formal punishment, though people might sometimes get suspended sentences on the condition they leave the state. This happened to a family member of mine--given a suspended sentence (enough for prison, not jail) and admonished by the judge that if he ever returned to the state he'd have to do the time. (Said family member never did return. They weren't a resident there, anyhow, but a resident of an adjacent state.) Today it would be considered unconstitutional, which is a real shame as forcing someone to leave what might be an enabling environment (e.g. running with a bad crowd) is often the best remedy for all involved, particularly the person misbehaving.
It is still used for bad cops. Instead of being prosecuted, they are let go, and hired into the next jurisdiction over.
For example, consider pottery, and the invention of glazes. It's generally thought that the invention of the ore -> metal process involved potters experimenting with different glazes and finding lumps of metal after the firing process was complete.
With toxic plants, well, most peoples kept domesticated animals and would probably use them to test the toxicity of potential food sources. Feed it to the chickens, pigs, llamas, etc. and see what happens. Soak the potential food source in water, see what happens. Try adding other substances, like charcoal or clay, and see what happens.
Why don't people recognize this? Simple - infantilization of native peoples as a justification for the ravages of European colonialism.
