WEBVTT - From the Vault: Mushroom Foraging, Part 2

0:00:05.720 --> 0:00:08.239
<v Speaker 1>Hey, welcome to Stuff to Blow your Mind. My name

0:00:08.280 --> 0:00:11.440
<v Speaker 1>is Robert Lamb and I'm Joe McCormick, and it's Saturday.

0:00:11.480 --> 0:00:13.640
<v Speaker 1>Time to go into the vault for an older episode.

0:00:13.800 --> 0:00:17.840
<v Speaker 1>This is Mushroom Foraging Part two. Part one was last Saturday.

0:00:17.880 --> 0:00:26.200
<v Speaker 1>This episode originally published September. Here you go, Welcome to

0:00:26.239 --> 0:00:35.800
<v Speaker 1>Stuff to Blow your Mind, production of My Heart Radio. Hey,

0:00:35.960 --> 0:00:37.879
<v Speaker 1>welcome to Stuff to Blow your Mind. My name is

0:00:37.960 --> 0:00:40.640
<v Speaker 1>Robert Lamb and I'm Joe McCormick, and it's part two

0:00:40.680 --> 0:00:44.240
<v Speaker 1>of Mushroom Foraging. We we started going into the woods

0:00:44.280 --> 0:00:47.199
<v Speaker 1>and we got lost, and uh so we had to

0:00:47.400 --> 0:00:49.120
<v Speaker 1>we had to say, you know what, this is actually

0:00:49.159 --> 0:00:51.919
<v Speaker 1>two episodes. Here we are again with part two. All right,

0:00:52.000 --> 0:00:54.720
<v Speaker 1>let's jump right in. So we already talked about how

0:00:54.840 --> 0:00:58.440
<v Speaker 1>mushroom hunting appears to be this really popular activity in Russia,

0:00:58.480 --> 0:01:01.520
<v Speaker 1>and this goes way back and so popular that there

0:01:01.520 --> 0:01:04.160
<v Speaker 1>are these common media stories about people getting lost in

0:01:04.200 --> 0:01:07.000
<v Speaker 1>the wilderness because they went into a trance while mushroom

0:01:07.040 --> 0:01:09.679
<v Speaker 1>hunting and then they couldn't find their way home. But

0:01:09.720 --> 0:01:13.600
<v Speaker 1>apparently things are very similar in Poland. It's also a

0:01:13.680 --> 0:01:18.080
<v Speaker 1>very common activity to go mushroom hunting in Poland. And Uh.

0:01:18.120 --> 0:01:22.160
<v Speaker 1>The Polish romantic poet Adam mits Kevitch, who lived from

0:01:23.520 --> 0:01:28.000
<v Speaker 1>eighteen fifty five, wrote famously about mushroom foraging in his

0:01:28.120 --> 0:01:32.399
<v Speaker 1>epic poem pan Tadash. And so I was looking at

0:01:32.400 --> 0:01:35.200
<v Speaker 1>this in a few different translations. I think the clearest one,

0:01:35.720 --> 0:01:39.040
<v Speaker 1>unfortunately doesn't go for the whole poetry and meter of it.

0:01:39.040 --> 0:01:42.920
<v Speaker 1>It's a prose translation by George Rapaul Noyus. But I

0:01:42.920 --> 0:01:45.679
<v Speaker 1>think this will give the best sense of the passage,

0:01:45.760 --> 0:01:47.840
<v Speaker 1>maybe losing a bit of the music. Are you ready,

0:01:47.920 --> 0:01:52.400
<v Speaker 1>Robert Okay? So there are these characters who are The

0:01:52.440 --> 0:01:56.880
<v Speaker 1>basic drama of Pantadash is about this conflict between these

0:01:56.920 --> 0:01:59.520
<v Speaker 1>clans over some kind of real estate dispute. I've never

0:01:59.600 --> 0:02:01.600
<v Speaker 1>read the whole thing, but I like the parts I

0:02:01.640 --> 0:02:03.520
<v Speaker 1>have read. And and so it's got all these, uh,

0:02:03.560 --> 0:02:07.560
<v Speaker 1>these fancy ladies and lads going out to hunt for

0:02:07.640 --> 0:02:10.400
<v Speaker 1>mushrooms in the forest, and they've announced that, you know,

0:02:10.400 --> 0:02:13.799
<v Speaker 1>whichever lad finds the fanciest mushroom will get to sit

0:02:13.880 --> 0:02:16.280
<v Speaker 1>next to the prettiest girl in the castle. And it's

0:02:16.320 --> 0:02:19.600
<v Speaker 1>that kind of thing. Uh. And so it goes into

0:02:19.600 --> 0:02:23.679
<v Speaker 1>the section on mushrooms, quote of mushrooms, there were plenty.

0:02:23.800 --> 0:02:28.000
<v Speaker 1>The lads gathered the fair cheeked fox mushrooms, so famous

0:02:28.000 --> 0:02:31.560
<v Speaker 1>in the Lithuanian songs as the emblem of maidenhood. For

0:02:31.639 --> 0:02:35.480
<v Speaker 1>the worms do not eat them, and marvelous to say

0:02:35.520 --> 0:02:39.280
<v Speaker 1>no insect alights on them. The young ladies hunted for

0:02:39.360 --> 0:02:42.960
<v Speaker 1>the slender pine lover, which the song calls the kernel

0:02:43.240 --> 0:02:45.880
<v Speaker 1>of the mushrooms. And that's colonel like the military rank,

0:02:45.960 --> 0:02:49.160
<v Speaker 1>not like popcorn. I don't know why it wouldn't be

0:02:49.160 --> 0:02:53.680
<v Speaker 1>the general of mushrooms. But moving on, all were eager

0:02:53.760 --> 0:02:57.840
<v Speaker 1>for the orange agaric. This, though of more modest stature

0:02:57.919 --> 0:03:01.239
<v Speaker 1>and less famous in song, is still the most delicious,

0:03:01.520 --> 0:03:04.760
<v Speaker 1>whether fresh or salted, whether in autumn or in winter.

0:03:05.240 --> 0:03:09.680
<v Speaker 1>But the snochal gathered the toadstool flybain. The remainder of

0:03:09.680 --> 0:03:13.720
<v Speaker 1>the mushroom family, are despised because they are injurious or

0:03:13.720 --> 0:03:17.560
<v Speaker 1>of poor flavor, But they are not useless. They give

0:03:17.600 --> 0:03:20.720
<v Speaker 1>food to beasts and shelter to insects, and are an

0:03:20.840 --> 0:03:24.720
<v Speaker 1>ornament to the groves. On the green cloth of the meadows,

0:03:24.720 --> 0:03:28.560
<v Speaker 1>they rise up like lines of table dishes. Here are

0:03:28.600 --> 0:03:32.760
<v Speaker 1>the leaf mushrooms with their rounded borders, silver, yellow, and

0:03:32.880 --> 0:03:36.760
<v Speaker 1>red like little glasses filled with various sorts of wine,

0:03:37.280 --> 0:03:40.960
<v Speaker 1>the coslac like the bulging bottom of an upturned cup,

0:03:41.440 --> 0:03:46.880
<v Speaker 1>the funnels like slender champagne glasses, the round white, broad

0:03:47.120 --> 0:03:51.160
<v Speaker 1>flat white ease like china coffee cups filled with milk,

0:03:51.600 --> 0:03:54.760
<v Speaker 1>and the round puff ball filled with a blackish dust

0:03:55.040 --> 0:03:58.120
<v Speaker 1>like a pepper shaker. The names of the others are

0:03:58.160 --> 0:04:01.680
<v Speaker 1>known only in the language of hay errors or wolves

0:04:01.720 --> 0:04:05.240
<v Speaker 1>by men. They have not been christened, but they are innumerable.

0:04:05.800 --> 0:04:09.120
<v Speaker 1>No one deigns to touch the wolf for hair varieties,

0:04:09.360 --> 0:04:12.600
<v Speaker 1>but whenever a person bends down to them, he straightaway

0:04:12.800 --> 0:04:16.640
<v Speaker 1>perceives his mistake, grows angry, and breaks the mushroom or

0:04:16.720 --> 0:04:20.280
<v Speaker 1>kicks it with his foot, in thus defiling the grass.

0:04:20.279 --> 0:04:24.720
<v Speaker 1>He acts with great indiscretion. I like at the end

0:04:24.760 --> 0:04:26.800
<v Speaker 1>there he gets a little bit offended on behalf of

0:04:26.800 --> 0:04:29.120
<v Speaker 1>the grass. I guess I'm not sure I fully understand

0:04:29.160 --> 0:04:31.960
<v Speaker 1>the meaning of that last statement, but I wanted to

0:04:31.960 --> 0:04:34.200
<v Speaker 1>look at a couple of things about this passage. Um.

0:04:34.279 --> 0:04:37.320
<v Speaker 1>So one is that first, while while Russian and Polish

0:04:37.360 --> 0:04:41.760
<v Speaker 1>cultures are considered to have a great affinity for mushrooms,

0:04:41.800 --> 0:04:45.080
<v Speaker 1>making them generally Mico philick in some terminology that will

0:04:45.120 --> 0:04:48.880
<v Speaker 1>address a little bit later in the episode. Uh, this doesn't,

0:04:48.880 --> 0:04:54.679
<v Speaker 1>of course, manifest as a love for all mushrooms unqualified. Instead,

0:04:54.720 --> 0:04:58.560
<v Speaker 1>it seems to me that the mushroom loving culture actually

0:04:58.560 --> 0:05:02.440
<v Speaker 1>has a highly discriminated eating I from mushrooms, noticing much

0:05:02.480 --> 0:05:06.680
<v Speaker 1>more the important and perhaps life saving differences between varieties.

0:05:06.720 --> 0:05:10.800
<v Speaker 1>So like a mushroom culture doesn't just love mushrooms. It's

0:05:10.839 --> 0:05:13.719
<v Speaker 1>more like they really love the good ones and really

0:05:13.920 --> 0:05:17.919
<v Speaker 1>hate the bad ones. But of course plenty of mushroom

0:05:18.000 --> 0:05:21.880
<v Speaker 1>hunting and accidental mushroom poisoning happens even in the modern era.

0:05:21.920 --> 0:05:25.320
<v Speaker 1>In Poland, I was looking at a scientific report compiling

0:05:25.360 --> 0:05:28.440
<v Speaker 1>cases of mushroom poisoning in Poland from the year's nineteen

0:05:28.480 --> 0:05:32.000
<v Speaker 1>sixty two to nineteen sixty seven by an author named

0:05:32.040 --> 0:05:37.000
<v Speaker 1>Eliza Lewandowska, and this was called Mushroom Poisoning in Poland

0:05:37.000 --> 0:05:39.919
<v Speaker 1>in the years nineteen sixty two to sixty seven. Species

0:05:39.920 --> 0:05:43.560
<v Speaker 1>of poisonous fungi. Now there's no surprise at all here

0:05:43.680 --> 0:05:47.760
<v Speaker 1>that the species representing the most danger was our old

0:05:47.839 --> 0:05:52.120
<v Speaker 1>friend Amanita feloides or the deathcap mushroom. We we've talked

0:05:52.120 --> 0:05:56.040
<v Speaker 1>about this already, right, yes, now, this one was responsible

0:05:56.320 --> 0:05:58.720
<v Speaker 1>for at least four hundred and sixty one cases of

0:05:58.720 --> 0:06:01.800
<v Speaker 1>poisoning and a hundred and twenty six deaths by this survey.

0:06:02.440 --> 0:06:04.800
<v Speaker 1>A commonly cited figure that I've seen elsewhere is that

0:06:04.960 --> 0:06:10.640
<v Speaker 1>death caps today represent more than of fatal mushroom poisonings worldwide.

0:06:10.640 --> 0:06:13.120
<v Speaker 1>So so they're the real bad boy in terms of

0:06:13.240 --> 0:06:17.400
<v Speaker 1>accidental accidental mushroom poisoning. Um. But I was also reading

0:06:17.400 --> 0:06:23.360
<v Speaker 1>about how the specific way that Amanda filoids kills is deceptive,

0:06:23.440 --> 0:06:27.920
<v Speaker 1>lee devious. So when somebody eats this mushroom, it's not

0:06:27.960 --> 0:06:30.040
<v Speaker 1>necessarily what you would picture where you eat it and

0:06:30.080 --> 0:06:33.000
<v Speaker 1>then you're immediately doubled over in pain and you know,

0:06:33.040 --> 0:06:37.040
<v Speaker 1>and hallucinating and sweating with a fever and screaming. Instead,

0:06:37.120 --> 0:06:41.680
<v Speaker 1>when somebody eats the Amanda floids, it doesn't necessarily cause

0:06:41.720 --> 0:06:45.400
<v Speaker 1>any immediate pain or discomfort. In fact, people often don't

0:06:45.440 --> 0:06:48.320
<v Speaker 1>have any symptoms at all for many hours I've read,

0:06:48.360 --> 0:06:51.479
<v Speaker 1>sometimes maybe six hours later, sometimes even not until like

0:06:51.520 --> 0:06:55.640
<v Speaker 1>a full day later. And then the cramps and the

0:06:55.720 --> 0:06:59.240
<v Speaker 1>nausea and the vomiting and the diarrhea. Set in, and

0:06:59.440 --> 0:07:01.840
<v Speaker 1>I've read that this can make it easy to mistake

0:07:01.920 --> 0:07:04.920
<v Speaker 1>the poisoning for something else. You might think you've got

0:07:04.920 --> 0:07:07.520
<v Speaker 1>a stomach bug or whatever because of the length of

0:07:07.560 --> 0:07:10.440
<v Speaker 1>time between eating the mushroom and the onset of symptoms.

0:07:11.000 --> 0:07:13.680
<v Speaker 1>And uh. And at this point, after the symptoms set in,

0:07:14.120 --> 0:07:17.800
<v Speaker 1>they can sometimes even retreat, they can grow milder if

0:07:17.840 --> 0:07:21.000
<v Speaker 1>the patient is properly cared for, properly hydrated, and all that.

0:07:21.920 --> 0:07:24.920
<v Speaker 1>The entire time the amanita toxins are in the background,

0:07:25.000 --> 0:07:28.960
<v Speaker 1>just massacring cells in the liver and harming the kidneys,

0:07:29.000 --> 0:07:33.440
<v Speaker 1>eventually leading to organ failure and eventually to death. And

0:07:33.800 --> 0:07:37.640
<v Speaker 1>I don't know that there's there's something kind of especially

0:07:37.760 --> 0:07:41.200
<v Speaker 1>terrifying about that that there's this You can have this

0:07:41.360 --> 0:07:44.080
<v Speaker 1>false sense that things are getting better and that, oh,

0:07:44.120 --> 0:07:46.400
<v Speaker 1>I'm actually feeling a little bit better than I was earlier,

0:07:46.480 --> 0:07:48.760
<v Speaker 1>or maybe I'm not even feeling bad at all, while

0:07:48.840 --> 0:07:52.840
<v Speaker 1>the mushroom is actively killing your vital organs. I think

0:07:52.840 --> 0:07:56.600
<v Speaker 1>it also underlines just the sort of precision that had

0:07:56.640 --> 0:08:00.280
<v Speaker 1>to take place in figuring out the properties of theirs

0:08:00.440 --> 0:08:04.320
<v Speaker 1>mushrooms and and other organisms in one's environment, you know,

0:08:04.760 --> 0:08:08.040
<v Speaker 1>because this is clearly something where you you would have

0:08:08.080 --> 0:08:11.440
<v Speaker 1>to do a little detective work to figure out it. Yeah,

0:08:11.440 --> 0:08:16.600
<v Speaker 1>exactly what had caused this awful illness in the individual. Exactly.

0:08:16.880 --> 0:08:19.960
<v Speaker 1>But in in second place for poisonings was a species

0:08:20.040 --> 0:08:23.240
<v Speaker 1>that is also interesting and and requires a similar kind

0:08:23.280 --> 0:08:26.920
<v Speaker 1>of precision, but with a different difficulty. I don't think

0:08:26.920 --> 0:08:29.360
<v Speaker 1>we've talked about this one yet. The second place in

0:08:29.400 --> 0:08:32.640
<v Speaker 1>the Polish survey for for most poisoning and death was

0:08:32.800 --> 0:08:38.200
<v Speaker 1>gyrometra esculenta, or the false moral. Mushroom. Uh, that's moral

0:08:38.320 --> 0:08:42.040
<v Speaker 1>like m O R E L moral mushrooms dot morals

0:08:42.080 --> 0:08:46.560
<v Speaker 1>you know, doing good h Yeah, And so in this survey,

0:08:46.760 --> 0:08:49.880
<v Speaker 1>the false moral was responsible for a hundred and sixty

0:08:49.960 --> 0:08:53.360
<v Speaker 1>four cases of poisoning and ten deaths in this time,

0:08:53.400 --> 0:08:56.800
<v Speaker 1>in the sixties. Now, the false moral is a very

0:08:56.840 --> 0:09:00.280
<v Speaker 1>strange and interesting case study in fungal toxicity because, first

0:09:00.280 --> 0:09:03.720
<v Speaker 1>of all, it looks crazy. It looks like a brain

0:09:03.880 --> 0:09:05.720
<v Speaker 1>on a stick, or not even a normal brain. It

0:09:05.760 --> 0:09:08.880
<v Speaker 1>looks like if you tried to make a raisin out

0:09:08.920 --> 0:09:12.680
<v Speaker 1>of a brain. Yeah, it kind of looks like what

0:09:12.760 --> 0:09:18.120
<v Speaker 1>you have, mushroom but ground chuck, you know. Yeah, it's

0:09:18.120 --> 0:09:22.240
<v Speaker 1>got the little grinder extrusion patterns. Yeah, it does. It

0:09:22.480 --> 0:09:24.240
<v Speaker 1>looks kind of like it's come out of a machine

0:09:24.280 --> 0:09:26.760
<v Speaker 1>in a way. I agree, had an extruded kind of

0:09:26.840 --> 0:09:29.719
<v Speaker 1>appearance to it. But a lot of delicious mushrooms look

0:09:29.840 --> 0:09:32.640
<v Speaker 1>very strange and very unlike other foods we eat. So

0:09:32.840 --> 0:09:37.000
<v Speaker 1>you know, that's fine. Um. But but gyrometra is an

0:09:37.040 --> 0:09:40.400
<v Speaker 1>interesting case because the toxicity seems to vary a lot.

0:09:40.880 --> 0:09:43.640
<v Speaker 1>Just one example I was reading in a stat pearls

0:09:43.760 --> 0:09:48.120
<v Speaker 1>entry by Horowitz, Kong and Horowitz and the author's report quote,

0:09:48.480 --> 0:09:52.760
<v Speaker 1>most poisonings occur in Eastern Europe, particularly in the conifer

0:09:52.840 --> 0:09:57.439
<v Speaker 1>forests of Germany, Poland, and Finland. In North America, most

0:09:57.480 --> 0:10:01.720
<v Speaker 1>exposures occur in Michigan, although I less toxic variety grows

0:10:01.800 --> 0:10:04.760
<v Speaker 1>west of the Rockies and has been clustered in Idaho

0:10:04.840 --> 0:10:08.920
<v Speaker 1>and Western Canada. Exposures occur mostly in the spring, unlike

0:10:08.920 --> 0:10:13.400
<v Speaker 1>other serious mushroom poisonings such as Amanita filoids, which occur

0:10:13.600 --> 0:10:18.080
<v Speaker 1>more commonly in the fall. So there's this geographical distribution

0:10:18.120 --> 0:10:21.200
<v Speaker 1>I've read about how there are different rates of poisoning

0:10:21.320 --> 0:10:25.200
<v Speaker 1>from the false morale depending on where the mushroom was grown.

0:10:25.440 --> 0:10:28.480
<v Speaker 1>You know, in in different countries and at different altitudes

0:10:28.600 --> 0:10:30.720
<v Speaker 1>and things like that. It seems to vary a lot

0:10:31.400 --> 0:10:34.160
<v Speaker 1>depending on you know, what local strain you're getting, and

0:10:34.240 --> 0:10:38.600
<v Speaker 1>possibly due to interactions with you know, with the body

0:10:38.679 --> 0:10:41.400
<v Speaker 1>of the person who eats it. Another thing I've read

0:10:41.480 --> 0:10:44.079
<v Speaker 1>is that poisoning is here are much more common when

0:10:44.080 --> 0:10:47.600
<v Speaker 1>these mushrooms are eaten raw. Now, there's one thing that

0:10:47.679 --> 0:10:51.520
<v Speaker 1>poison control authorities often emphasize, which is that you should

0:10:51.559 --> 0:10:55.840
<v Speaker 1>not use intuitive smell and taste senses to figure out

0:10:55.920 --> 0:10:58.959
<v Speaker 1>what is poisonous in the mushroom world, because even though

0:10:58.960 --> 0:11:02.720
<v Speaker 1>our senses of smell and taste are certainly evolved to

0:11:02.800 --> 0:11:05.400
<v Speaker 1>help us figure out what's good to eat, they are

0:11:05.520 --> 0:11:09.400
<v Speaker 1>not an infallible guide. And a great example of this

0:11:09.559 --> 0:11:12.280
<v Speaker 1>is once again the deathcap mushroom, one of the most

0:11:12.360 --> 0:11:16.000
<v Speaker 1>dangerous mushrooms to humans and the most deadly one in Poland.

0:11:16.080 --> 0:11:18.560
<v Speaker 1>During that survey we were just talking about the deathcap

0:11:18.679 --> 0:11:22.400
<v Speaker 1>mushroom does not taste like poison. It reportedly does not

0:11:22.440 --> 0:11:26.000
<v Speaker 1>taste bitter, does not taste sour, does not you know,

0:11:26.160 --> 0:11:28.920
<v Speaker 1>set your mouth on fire with needles going into your tongue.

0:11:29.280 --> 0:11:33.360
<v Speaker 1>In fact, it is widely said to be absolutely delicious.

0:11:33.840 --> 0:11:37.520
<v Speaker 1>There are people who have had these hepatotoxic mushrooms absolutely

0:11:37.640 --> 0:11:41.360
<v Speaker 1>destroy their liver. But they report that, you know, before

0:11:41.440 --> 0:11:43.679
<v Speaker 1>the pain and the nausea set in, six hours later,

0:11:43.760 --> 0:11:46.560
<v Speaker 1>twenty four hours later, when whenever it is while they're

0:11:46.559 --> 0:11:49.600
<v Speaker 1>eating these mushrooms, they are some of the best tasting

0:11:49.679 --> 0:11:53.199
<v Speaker 1>mushrooms that they've ever had. They're said to smell sweet

0:11:53.320 --> 0:11:58.120
<v Speaker 1>like honey and taste absolutely delightful, sauteed and butter. Don't

0:11:58.240 --> 0:12:00.880
<v Speaker 1>do this, don't It's not worth it. It will kill you.

0:12:01.320 --> 0:12:04.520
<v Speaker 1>Do not take the death cap challenge something like that

0:12:04.559 --> 0:12:07.840
<v Speaker 1>on YouTube. No, not at all. But but this does

0:12:07.880 --> 0:12:11.839
<v Speaker 1>bring me back to an interesting observation from Miskovich, which

0:12:12.000 --> 0:12:14.880
<v Speaker 1>is that some of the species of mushroom that are

0:12:15.000 --> 0:12:17.960
<v Speaker 1>detestable to humankind, and I'm sure the death cap is

0:12:18.000 --> 0:12:21.720
<v Speaker 1>one of these in in his survey, they're known in

0:12:21.760 --> 0:12:24.680
<v Speaker 1>the cultures of what he calls the wolves or the hairs,

0:12:24.800 --> 0:12:27.920
<v Speaker 1>you know, the language of wolves or rabbits. Now, you

0:12:28.000 --> 0:12:30.280
<v Speaker 1>might think that this is just another folk tale about

0:12:30.280 --> 0:12:32.520
<v Speaker 1>the animals of the forest, but I think that this

0:12:32.600 --> 0:12:36.920
<v Speaker 1>could actually be based on real observation, because despite being

0:12:37.000 --> 0:12:39.560
<v Speaker 1>one of the most deadly fungui to humans. It is

0:12:39.600 --> 0:12:43.120
<v Speaker 1>not necessarily deadly to everything in the forest all of

0:12:43.160 --> 0:12:46.920
<v Speaker 1>the time. It came across one statement about this when

0:12:46.920 --> 0:12:49.640
<v Speaker 1>I was reading an article about the spread of the

0:12:49.679 --> 0:12:52.839
<v Speaker 1>death cap mushroom throughout North America, and this was by

0:12:52.840 --> 0:12:56.520
<v Speaker 1>Craig Child's in The Atlantic. It's a very interesting article.

0:12:56.600 --> 0:13:00.800
<v Speaker 1>It's worth reading. A Child's talks about how death mushrooms

0:13:01.240 --> 0:13:05.160
<v Speaker 1>naturally live in a symbiotic relationship with host trees. And

0:13:05.200 --> 0:13:07.640
<v Speaker 1>we've talked about how several mushroom species are like this.

0:13:07.800 --> 0:13:10.760
<v Speaker 1>They attached themselves to the roots of trees, and they

0:13:10.760 --> 0:13:14.240
<v Speaker 1>sort of trade resources between them, uh and so that

0:13:14.320 --> 0:13:16.920
<v Speaker 1>they're able to get some nutrition from from tree roots.

0:13:17.240 --> 0:13:19.200
<v Speaker 1>And this is the reason that you will often find

0:13:19.240 --> 0:13:22.040
<v Speaker 1>them sort of in a ring of deadly fruiting bodies

0:13:22.080 --> 0:13:25.760
<v Speaker 1>around the roots of a central tree trunk. But their

0:13:25.800 --> 0:13:28.840
<v Speaker 1>spores don't naturally tend to spread very far, at least

0:13:28.880 --> 0:13:33.480
<v Speaker 1>under normal circumstances, and it has taken human intervention to

0:13:33.720 --> 0:13:37.760
<v Speaker 1>really set them spreading far and wide. Specifically, what's named

0:13:37.800 --> 0:13:41.320
<v Speaker 1>by Craig Child's in this article is that deathcap mushrooms

0:13:41.320 --> 0:13:46.800
<v Speaker 1>have been spreaded spreading rapidly throughout northwest North America, riding

0:13:46.840 --> 0:13:51.040
<v Speaker 1>along on the roots of imported European trees, like imported

0:13:51.080 --> 0:13:53.560
<v Speaker 1>sweet chestnut trees and beech trees. So you get this

0:13:53.600 --> 0:13:56.920
<v Speaker 1>fancy tree from Europe, it's got deathcap mushrooms in a

0:13:56.960 --> 0:13:59.600
<v Speaker 1>relationship with it. You bring the tree over here planted,

0:13:59.679 --> 0:14:03.640
<v Speaker 1>and it brings the poisonous mushrooms with it. But anyway,

0:14:04.200 --> 0:14:07.040
<v Speaker 1>the reason I brought this article up was that there's

0:14:07.120 --> 0:14:11.760
<v Speaker 1>this quick side note where Child's mentions that that squirrels

0:14:11.760 --> 0:14:15.760
<v Speaker 1>and rabbits have sometimes been observed to eat deathcap mushrooms

0:14:15.800 --> 0:14:19.080
<v Speaker 1>without being harmed at all, which sounds again like like

0:14:19.200 --> 0:14:22.520
<v Speaker 1>mits Kevich, like that, you know, the hairs don't really

0:14:22.560 --> 0:14:26.680
<v Speaker 1>mind the mushrooms that the humans find absolutely detestable. And

0:14:26.720 --> 0:14:29.000
<v Speaker 1>so I think that's interesting. It's another indication of what

0:14:29.040 --> 0:14:32.280
<v Speaker 1>you should not do. You should not watch what animals

0:14:32.320 --> 0:14:34.760
<v Speaker 1>eat in the forest to determine what would be okay

0:14:34.800 --> 0:14:36.640
<v Speaker 1>for you to eat, because they may be able to

0:14:37.360 --> 0:14:41.000
<v Speaker 1>digest and metabolize stuff just fine that would absolutely kill

0:14:41.080 --> 0:14:43.920
<v Speaker 1>you with just a few mouthfuls. And also in this

0:14:44.240 --> 0:14:49.280
<v Speaker 1>just another reason to respect the mighty squirrel. Yes, yeah,

0:14:49.360 --> 0:14:51.320
<v Speaker 1>I saw squirrels were thrown in there too, So I'm

0:14:51.360 --> 0:14:55.640
<v Speaker 1>sure our fans are gonna gonna go hog wild about that. Sure,

0:14:55.800 --> 0:15:01.400
<v Speaker 1>meme away, yeah me until you drop. But one last

0:15:01.400 --> 0:15:03.440
<v Speaker 1>thing I wanted to add about this was I saw

0:15:03.480 --> 0:15:06.880
<v Speaker 1>some mushroom enthusiasts online just in common sections and stuff,

0:15:07.120 --> 0:15:10.280
<v Speaker 1>saying that they kind of wish they had whatever resistance

0:15:10.440 --> 0:15:14.240
<v Speaker 1>these rabbits have to to the death cap toxicity is

0:15:14.280 --> 0:15:16.640
<v Speaker 1>because they would love to taste them. For one, since

0:15:16.720 --> 0:15:19.560
<v Speaker 1>you know, by all accounts, when people eat them, even

0:15:19.600 --> 0:15:24.400
<v Speaker 1>though it kills them, they are very tasty. Interesting. Um,

0:15:25.240 --> 0:15:28.200
<v Speaker 1>you know, in our previous episode we mentioned were mentioned

0:15:28.200 --> 0:15:31.680
<v Speaker 1>a few different mushroom foraging cultures, and I believe Scottish

0:15:32.000 --> 0:15:36.560
<v Speaker 1>culture came up. As luck would have it, was watching uh,

0:15:36.240 --> 0:15:40.640
<v Speaker 1>the the TV adaptation of Outlander last night. Watching that, yeah,

0:15:40.640 --> 0:15:43.800
<v Speaker 1>and in the second episode what happens they're forging for mushrooms,

0:15:44.440 --> 0:15:47.480
<v Speaker 1>talking about them, the medicinal use of mushrooms and which

0:15:47.480 --> 0:15:50.000
<v Speaker 1>ones are good to eat and which ones are poisonous.

0:15:50.160 --> 0:15:53.600
<v Speaker 1>I found it rather interesting. Also castle they used in

0:15:53.600 --> 0:15:57.200
<v Speaker 1>that show, same castle they used in Highlander and in

0:15:57.320 --> 0:15:59.320
<v Speaker 1>Monty Python and the Holy Grail, So it's got that

0:15:59.360 --> 0:16:02.640
<v Speaker 1>going for it. So even in your ultimate kilt lift

0:16:02.720 --> 0:16:06.200
<v Speaker 1>or narrative. You cannot escape a good mushroom hunt, right,

0:16:06.240 --> 0:16:08.440
<v Speaker 1>I mean that's I mean you've got time travel in there,

0:16:08.480 --> 0:16:10.360
<v Speaker 1>so it's a it's it's a big part of the

0:16:10.360 --> 0:16:14.200
<v Speaker 1>plot apparently, at least as I can gather thus far. Well,

0:16:14.240 --> 0:16:16.760
<v Speaker 1>whether you're time traveling or not, whether you forge for

0:16:16.880 --> 0:16:19.160
<v Speaker 1>mushrooms or not, stay away from the death caps. Just

0:16:19.400 --> 0:16:21.640
<v Speaker 1>just don't even try it now. Of course, this is

0:16:21.720 --> 0:16:25.400
<v Speaker 1>this goes way back, this this basic um reality that

0:16:25.440 --> 0:16:28.920
<v Speaker 1>we're discussing here, and we've we've covered humanities hunter gatherer

0:16:29.000 --> 0:16:31.960
<v Speaker 1>past on the show before. I mean the basic is

0:16:31.960 --> 0:16:35.600
<v Speaker 1>you know, we're we're omnivores, and mushrooms have always been

0:16:35.640 --> 0:16:38.800
<v Speaker 1>on the table. Uh. Though, of course our ancestors had

0:16:38.840 --> 0:16:42.640
<v Speaker 1>to devise the expertise to avoid harmful species, as well

0:16:42.680 --> 0:16:45.520
<v Speaker 1>as figuring out which ones are beneficial, which ones can

0:16:45.560 --> 0:16:48.840
<v Speaker 1>be food, etcetera. Right. One of the resources we were

0:16:48.840 --> 0:16:52.800
<v Speaker 1>looking at for this section was Eric BoA's Wild Edible

0:16:52.800 --> 0:16:56.040
<v Speaker 1>Fun Guy. A Global Overview of their use and importance

0:16:56.080 --> 0:16:58.440
<v Speaker 1>to people. Yeah, it looks like this was a report

0:16:58.520 --> 0:17:01.360
<v Speaker 1>compiled for the Food MAgric Culture Organization of the u

0:17:01.520 --> 0:17:04.639
<v Speaker 1>N in two thousand four. Yeah, and uh and Boa

0:17:04.720 --> 0:17:07.800
<v Speaker 1>points out and mentioned a few different facts. He points

0:17:07.800 --> 0:17:10.680
<v Speaker 1>out here, first of all, wild edible fungi are collected

0:17:10.760 --> 0:17:13.679
<v Speaker 1>for food in more than eighty countries, and we're dealing

0:17:13.720 --> 0:17:18.400
<v Speaker 1>with more than one thousand, one hundred species. And interestingly enough,

0:17:18.720 --> 0:17:22.879
<v Speaker 1>some cultures may be viewed is microphobic being you know,

0:17:22.920 --> 0:17:27.679
<v Speaker 1>meaning there's a fear of mushrooms or a reluctance to

0:17:27.800 --> 0:17:32.000
<v Speaker 1>engage in mushroom consumption and foraging, while other cultures are

0:17:32.840 --> 0:17:36.560
<v Speaker 1>are microphilic meaning you know, the loving mushrooms, you know,

0:17:36.640 --> 0:17:39.720
<v Speaker 1>being open to those experiences in those quests, with English

0:17:39.760 --> 0:17:43.560
<v Speaker 1>culture standing interestingly enough as an example of of microphobic

0:17:44.040 --> 0:17:49.000
<v Speaker 1>UH culture, while Chinese culture, he mentions, is a strongly

0:17:49.200 --> 0:17:52.480
<v Speaker 1>micophilic culture. He points out that a lot of Chinese

0:17:52.520 --> 0:17:55.200
<v Speaker 1>writings on mushrooms have yet to be translated, but there's

0:17:55.240 --> 0:17:57.359
<v Speaker 1>a lot of material there. Now. I found this very

0:17:57.400 --> 0:18:01.359
<v Speaker 1>interesting because I've've certainly seen some documentaries um that really

0:18:01.400 --> 0:18:07.280
<v Speaker 1>focus in on on British and Scottish traditions regarding mushroom hunting. Yeah,

0:18:07.280 --> 0:18:10.640
<v Speaker 1>and of course that highlights that these designations. I've seen

0:18:10.680 --> 0:18:13.640
<v Speaker 1>these designations used by other people as well. Burtleson talks

0:18:13.640 --> 0:18:16.800
<v Speaker 1>about this, where you know, cultures that are predominantly microphobic

0:18:16.880 --> 0:18:19.639
<v Speaker 1>or microphilic, they're all gonna be relative, right Like, within

0:18:19.720 --> 0:18:22.520
<v Speaker 1>each of these broad cultures there will be subcultures and

0:18:22.560 --> 0:18:26.199
<v Speaker 1>individuals that sort of run against the grain. Um. But

0:18:26.359 --> 0:18:29.879
<v Speaker 1>on the note of of of Chinese culture being microphilic,

0:18:30.520 --> 0:18:33.280
<v Speaker 1>of course that comes through in in certain types of

0:18:33.320 --> 0:18:37.560
<v Speaker 1>ancient medical practices, but also in cuisine. And I just

0:18:37.600 --> 0:18:40.640
<v Speaker 1>think about one of my earliest memories of Chinese food.

0:18:40.640 --> 0:18:43.080
<v Speaker 1>I've loved Chinese food as long as I can remember,

0:18:43.119 --> 0:18:47.600
<v Speaker 1>but one of my earliest memories is of the unidentifiable

0:18:47.680 --> 0:18:50.520
<v Speaker 1>fungus within the Chinese soup I was eating, and how

0:18:50.640 --> 0:18:53.840
<v Speaker 1>much I loved it, and how how it was like

0:18:54.080 --> 0:18:56.040
<v Speaker 1>there was nothing else like this in my diet. I

0:18:56.040 --> 0:18:57.960
<v Speaker 1>guess it was probably a type of black fungus in

0:18:57.960 --> 0:19:00.600
<v Speaker 1>a hot and sour soup, and I is just like,

0:19:00.680 --> 0:19:03.119
<v Speaker 1>what is this? I have no idea. It's like something

0:19:03.119 --> 0:19:07.800
<v Speaker 1>from another planet, and it's delicious. But as to microphobia,

0:19:08.040 --> 0:19:12.520
<v Speaker 1>Burdleston mentions evidence of strains of microphobic thinking in many

0:19:12.560 --> 0:19:16.040
<v Speaker 1>of the historic common names for mushrooms and some European cultures,

0:19:16.400 --> 0:19:19.000
<v Speaker 1>for example, though today we think of French cuisine as

0:19:19.040 --> 0:19:23.840
<v Speaker 1>being very very pro mushroom. Historically, there was some French

0:19:23.880 --> 0:19:28.359
<v Speaker 1>aversion to mushrooms, like calling mushrooms things like eggs of

0:19:28.440 --> 0:19:33.160
<v Speaker 1>the devil or the devil's paint brush, or toads bread.

0:19:33.960 --> 0:19:37.600
<v Speaker 1>Of course, there's the English expression toad stool. In Danish

0:19:37.600 --> 0:19:41.320
<v Speaker 1>and Norwegian you have variations on PoTA hot toad's hat,

0:19:42.040 --> 0:19:45.000
<v Speaker 1>and in Germanic and Celtic cultures. Burtleson writes that you

0:19:45.040 --> 0:19:49.680
<v Speaker 1>sometimes see an association between mushrooms and witchcraft, and this

0:19:49.720 --> 0:19:53.120
<v Speaker 1>association may have played a role in keeping the British

0:19:53.119 --> 0:19:58.080
<v Speaker 1>aisles relatively microphobic for for many centuries. You know, I

0:19:58.119 --> 0:20:00.000
<v Speaker 1>can't help be reminded. I'm sure I've brought this up

0:20:00.040 --> 0:20:02.680
<v Speaker 1>up on the show before. Um, but there's that that

0:20:02.800 --> 0:20:06.119
<v Speaker 1>wonderful um a little bit in uh burd of Echos

0:20:06.119 --> 0:20:08.400
<v Speaker 1>the Name of the Rose, where there's the story of

0:20:08.400 --> 0:20:12.680
<v Speaker 1>of one monk. You know, it's like a multi multi cultural,

0:20:12.880 --> 0:20:16.840
<v Speaker 1>multi linguistic community of monks there, and one is talking

0:20:16.840 --> 0:20:19.960
<v Speaker 1>about having this pig that will accompany them into the

0:20:20.000 --> 0:20:24.440
<v Speaker 1>woods to search for truffles, and the the other monk

0:20:24.480 --> 0:20:27.800
<v Speaker 1>that's hearing this story is I believe German, and he

0:20:27.880 --> 0:20:30.600
<v Speaker 1>thinks that he's not saying truffle but to full, which

0:20:30.680 --> 0:20:33.119
<v Speaker 1>is a German for devil. So he thinks this is

0:20:33.119 --> 0:20:36.600
<v Speaker 1>a horrific story of this weird pig that will accompany

0:20:37.000 --> 0:20:39.520
<v Speaker 1>uh you into the woods so that you can seek

0:20:39.560 --> 0:20:42.800
<v Speaker 1>out the devil. I remember that moment, and that's oh man,

0:20:42.840 --> 0:20:45.280
<v Speaker 1>that's so emblematic of everything I love about Name of

0:20:45.320 --> 0:20:49.959
<v Speaker 1>the Rose. Now, in terms of the ancient uh uh

0:20:50.280 --> 0:20:53.040
<v Speaker 1>foraging for mushrooms and the use of mushrooms by by

0:20:53.080 --> 0:20:55.960
<v Speaker 1>human beings, you know, there's there's apparently evidence in what

0:20:56.080 --> 0:20:59.600
<v Speaker 1>is now Chile of mushroom consumption by humans thirteen thousand

0:20:59.720 --> 0:21:03.080
<v Speaker 1>years ago. Um Obsouly the iceman who we've mentioned on

0:21:03.080 --> 0:21:07.560
<v Speaker 1>the show before, who lived between thirty four UM hundred

0:21:07.680 --> 0:21:11.359
<v Speaker 1>and thirty bc uh somewhere in that area, was found

0:21:11.440 --> 0:21:14.560
<v Speaker 1>with two varieties of fungia on his person, one of

0:21:14.600 --> 0:21:17.840
<v Speaker 1>which we've discussed on our other show or previous other show.

0:21:17.880 --> 0:21:21.600
<v Speaker 1>Invention was likely a dried fungi used to help start fires,

0:21:21.640 --> 0:21:24.040
<v Speaker 1>but the other was a birch fungus that was likely

0:21:24.080 --> 0:21:27.480
<v Speaker 1>consumed for medicinal reasons, and so that the consumption of

0:21:27.560 --> 0:21:30.600
<v Speaker 1>mushrooms for culinary and or medicinal purposes dates back in

0:21:30.640 --> 0:21:33.760
<v Speaker 1>a number of ancient cultures. They're they're more examples of

0:21:33.760 --> 0:21:37.400
<v Speaker 1>this than we could easily cover on the show here. Uh.

0:21:37.400 --> 0:21:41.240
<v Speaker 1>And with the agricultural revolution came the eventuality of mushroom

0:21:41.240 --> 0:21:44.160
<v Speaker 1>cultivation as well. Though, as we previously touched on, there

0:21:44.200 --> 0:21:47.800
<v Speaker 1>are so many varieties that are resistant to cultivation. Yeah.

0:21:47.840 --> 0:21:50.399
<v Speaker 1>I think specifically a lot of the ones that you

0:21:50.440 --> 0:21:52.840
<v Speaker 1>think of that are most commonly used in food that

0:21:52.880 --> 0:21:56.720
<v Speaker 1>are the hardest to cultivate, or are the ones that are,

0:21:56.760 --> 0:22:00.399
<v Speaker 1>for my corpsal reasons, unable to be cultivated because they

0:22:00.400 --> 0:22:04.639
<v Speaker 1>exist in these symbiotic relationships with other plants, trees, and

0:22:04.760 --> 0:22:08.680
<v Speaker 1>forest atmospheres. And so the truffle is a common example,

0:22:09.160 --> 0:22:11.040
<v Speaker 1>but of course Sean trells are like this as well.

0:22:11.080 --> 0:22:14.840
<v Speaker 1>I believe also porcini mushrooms, uh, that it's just really

0:22:14.880 --> 0:22:18.679
<v Speaker 1>hard to recreate the conditions in which they arise. Yeah.

0:22:19.000 --> 0:22:23.200
<v Speaker 1>So even as as humanity inevitably be you know, began

0:22:23.240 --> 0:22:27.439
<v Speaker 1>to shift uh this revolution in neolithic times, uh, shifting

0:22:27.480 --> 0:22:30.520
<v Speaker 1>away from the hunter gather existence to one dependent on

0:22:30.960 --> 0:22:34.800
<v Speaker 1>intensive agriculture, there's kind of this you know, this tendency

0:22:34.840 --> 0:22:36.359
<v Speaker 1>to sort of think of that as Okay, well, you know,

0:22:36.400 --> 0:22:39.000
<v Speaker 1>you're just changing the way you live entirely, you're just

0:22:39.040 --> 0:22:41.399
<v Speaker 1>stopping where you are and now you're gonna grow plants,

0:22:41.400 --> 0:22:43.760
<v Speaker 1>and maybe mushroom foraging is one of those things that

0:22:43.880 --> 0:22:47.200
<v Speaker 1>remains outside of that tradition for these very reasons we've

0:22:47.240 --> 0:22:51.280
<v Speaker 1>been discussing. Um. However, this was quite interesting. I was

0:22:51.320 --> 0:22:53.280
<v Speaker 1>looking around for resources on this and I ran across

0:22:53.520 --> 0:22:57.000
<v Speaker 1>a paper published in the Royal Society b by Curtis w.

0:22:57.440 --> 0:23:01.679
<v Speaker 1>Uh Marine titled the Transition to Foraging for Dense and

0:23:01.720 --> 0:23:05.160
<v Speaker 1>Predictable Resources and It's Impact on the Evolution of modern humans.

0:23:05.760 --> 0:23:10.600
<v Speaker 1>And in this uh the the author um is discussing,

0:23:10.960 --> 0:23:13.320
<v Speaker 1>you know, this basic shift, but he points out, they

0:23:13.320 --> 0:23:15.760
<v Speaker 1>point out that there's another shift to consider. Quote the

0:23:15.800 --> 0:23:18.880
<v Speaker 1>foraging shift to dense and predictable resources is another key

0:23:18.920 --> 0:23:22.320
<v Speaker 1>milestone that had consequential impacts on the later part of

0:23:22.400 --> 0:23:26.840
<v Speaker 1>human evolution. Now, the basic idea here is that there

0:23:26.920 --> 0:23:30.120
<v Speaker 1>wasn't just this sudden shift from hunting and gathering to cultivation.

0:23:30.560 --> 0:23:34.000
<v Speaker 1>And there are many hypothesized explanations for this, but Marine

0:23:34.080 --> 0:23:37.440
<v Speaker 1>argues that hunting and gathering would have seen an increased

0:23:37.440 --> 0:23:41.200
<v Speaker 1>focus on dense and predictable resources. As such, this also

0:23:41.240 --> 0:23:45.159
<v Speaker 1>means that a given area becomes increasingly worth defending and

0:23:45.200 --> 0:23:48.600
<v Speaker 1>staking a claim to. Oh this is interesting. So this

0:23:48.640 --> 0:23:52.800
<v Speaker 1>could be the transition point between um between people who

0:23:52.840 --> 0:23:56.400
<v Speaker 1>just roam about following resources and consuming them wherever they

0:23:56.400 --> 0:23:59.040
<v Speaker 1>can be found. That and then on the other hand,

0:23:59.200 --> 0:24:02.720
<v Speaker 1>having far land in between. You could have places where

0:24:02.760 --> 0:24:06.960
<v Speaker 1>there are naturally high density resources that can be exploited

0:24:07.040 --> 0:24:10.200
<v Speaker 1>over and over that you might not be quite farming yet,

0:24:10.600 --> 0:24:14.920
<v Speaker 1>but might be worth defending as a stable territory. Yeah. Yeah,

0:24:14.960 --> 0:24:16.760
<v Speaker 1>And I have to admit I hadn't really thought about

0:24:16.800 --> 0:24:18.840
<v Speaker 1>this before. I without giving it a lot of thought.

0:24:18.840 --> 0:24:21.159
<v Speaker 1>I always just kind of, you know, had this this

0:24:21.280 --> 0:24:24.119
<v Speaker 1>inaccurate picture in my mind that was again like, okay,

0:24:24.119 --> 0:24:26.920
<v Speaker 1>we're not hundred gathers anymore, let's start growing this corn.

0:24:26.920 --> 0:24:29.320
<v Speaker 1>Why don't we? You know, like I don't. I didn't

0:24:29.320 --> 0:24:32.439
<v Speaker 1>really think about some of the potential, you know, for

0:24:32.440 --> 0:24:35.600
<v Speaker 1>for areas in between. This would be very interesting to explore.

0:24:35.640 --> 0:24:38.040
<v Speaker 1>Paired with something that came up in our Invention episodes

0:24:38.080 --> 0:24:40.600
<v Speaker 1>on Bread and Toast, where we talked about the studies

0:24:40.600 --> 0:24:44.320
<v Speaker 1>indicating that bread and may actually have been invented before

0:24:45.119 --> 0:24:49.240
<v Speaker 1>grain was was an agricultural product like people may have

0:24:49.320 --> 0:24:52.240
<v Speaker 1>been making and I think the archaeological evidence is that

0:24:52.280 --> 0:24:57.160
<v Speaker 1>people were making bread from wild grains and wild grasses

0:24:57.240 --> 0:25:00.720
<v Speaker 1>before they had farms and wheat. Yeah. Absolutely, It makes

0:25:00.720 --> 0:25:02.560
<v Speaker 1>me wonder if they were getting these grains from some

0:25:02.640 --> 0:25:04.560
<v Speaker 1>kind of like a location where there were a lot

0:25:04.600 --> 0:25:07.199
<v Speaker 1>of them growing together and could be exploited over and

0:25:07.240 --> 0:25:11.080
<v Speaker 1>over again. Yeah, exactly, Now marine rights to some all

0:25:11.080 --> 0:25:14.439
<v Speaker 1>this up quote. I hypothesize that the origin population for

0:25:14.520 --> 0:25:18.040
<v Speaker 1>modern humans made this shift to dense and predictable resources,

0:25:18.080 --> 0:25:21.719
<v Speaker 1>and thus was subject to high levels of territoriality and

0:25:21.840 --> 0:25:26.080
<v Speaker 1>intergroup conflict, which provided the selection regime for high levels

0:25:26.080 --> 0:25:30.919
<v Speaker 1>of cooperation with unrelated individuals within one's group. The downstream

0:25:30.960 --> 0:25:35.040
<v Speaker 1>effect was that all modern humans inherited these hyper pro

0:25:35.119 --> 0:25:39.639
<v Speaker 1>social provoclivities that are unique to our species. Now, to

0:25:39.720 --> 0:25:42.720
<v Speaker 1>bring this back to mushroom foraging, it is interesting to

0:25:42.800 --> 0:25:46.360
<v Speaker 1>process one's thoughts about the predictable times and places one

0:25:46.400 --> 0:25:50.040
<v Speaker 1>will find, say Chantrelle's or into the woods, and the

0:25:50.080 --> 0:25:53.400
<v Speaker 1>competitive feelings that they may force we may be forced

0:25:53.400 --> 0:25:56.680
<v Speaker 1>to confront during this. In fact, I understand that more

0:25:56.720 --> 0:26:00.240
<v Speaker 1>serious mushroom foragers are, you know, their loath to reveal

0:26:00.520 --> 0:26:04.360
<v Speaker 1>the secrets, uh, their secret places, their quote unquote honey spots,

0:26:04.960 --> 0:26:08.040
<v Speaker 1>the places where they can dependently find the best patches

0:26:08.080 --> 0:26:11.200
<v Speaker 1>of mushroom. Do you remember the story in Michael Pollen's

0:26:11.200 --> 0:26:15.560
<v Speaker 1>book where he's going hunting for psilocybin mushrooms with Paul Statements,

0:26:15.640 --> 0:26:17.960
<v Speaker 1>and he's going to great pains to try to tell

0:26:18.000 --> 0:26:21.440
<v Speaker 1>you what he's doing without revealing the site of Paul

0:26:21.480 --> 0:26:26.400
<v Speaker 1>statements mushroom psh Oh yeah, yeah, because Paul really doesn't

0:26:26.440 --> 0:26:28.119
<v Speaker 1>want people to know where he gets him that's his

0:26:28.160 --> 0:26:32.160
<v Speaker 1>honey spot. Now, I think though that, yeah, you can

0:26:32.160 --> 0:26:35.520
<v Speaker 1>certainly see that with plants, especially, how this could be

0:26:35.680 --> 0:26:40.400
<v Speaker 1>this intermediary zone between hunting and gathering and cultivation where

0:26:40.440 --> 0:26:42.719
<v Speaker 1>you realize, oh, well, the the wheat that we can

0:26:42.720 --> 0:26:45.800
<v Speaker 1>make into bread, it grows really well here. Uh, this

0:26:45.880 --> 0:26:47.800
<v Speaker 1>is a place that we need to keep secret or

0:26:47.840 --> 0:26:51.200
<v Speaker 1>even protect from other other individuals. This is our spot,

0:26:51.240 --> 0:26:53.880
<v Speaker 1>this is our sacred spot that we return to. It's

0:26:53.880 --> 0:26:57.679
<v Speaker 1>a very interesting possibility. I wonder what what would be

0:26:57.720 --> 0:26:59.760
<v Speaker 1>the evidence that you could find to back that up.

0:27:00.000 --> 0:27:01.520
<v Speaker 1>I don't know, I have to keep thinking about that.

0:27:02.040 --> 0:27:03.920
<v Speaker 1>All right, we're gonna take a quick break, but we'll

0:27:03.920 --> 0:27:10.320
<v Speaker 1>be right back. Thank and we're back. Now. Another interesting

0:27:10.840 --> 0:27:13.720
<v Speaker 1>topic to to consider in all of this is that

0:27:14.119 --> 0:27:18.800
<v Speaker 1>that there is essentially a foraging gene uh So the

0:27:19.119 --> 0:27:22.160
<v Speaker 1>key gene of note in most studies, especially with fruit

0:27:22.160 --> 0:27:26.240
<v Speaker 1>flies and fruit flies, it's p r KG one uh

0:27:26.280 --> 0:27:28.720
<v Speaker 1>and uh this is um this is something that we

0:27:28.800 --> 0:27:33.240
<v Speaker 1>see presented in a wide variety of animals, from fruit

0:27:33.240 --> 0:27:35.960
<v Speaker 1>flies to even humans. But p r KG one is

0:27:36.000 --> 0:27:39.600
<v Speaker 1>president fruit flies and has previously been shown to influence

0:27:39.640 --> 0:27:43.920
<v Speaker 1>foraging behaviors. Researchers and studies that I think date back

0:27:43.960 --> 0:27:47.080
<v Speaker 1>to at least night have looked at this, and multiple

0:27:47.119 --> 0:27:50.160
<v Speaker 1>researchers found that one variant of the gene and fruit

0:27:50.200 --> 0:27:54.240
<v Speaker 1>flies induces what is called sitter behavior and in the

0:27:54.280 --> 0:27:57.960
<v Speaker 1>other's rover behavior. Now, the difference here is that when

0:27:57.960 --> 0:28:02.120
<v Speaker 1>a sitter enters an area can taining fruit, the they

0:28:02.160 --> 0:28:05.480
<v Speaker 1>scalut the perimeter of the area and then they move inward.

0:28:05.720 --> 0:28:07.320
<v Speaker 1>They sort of you know, they scouted out, they make

0:28:07.359 --> 0:28:10.680
<v Speaker 1>a perimeter, and then they move in. Rovers instead move

0:28:10.920 --> 0:28:15.280
<v Speaker 1>right in and go for the first fruit they encounter. Interesting, Now,

0:28:15.320 --> 0:28:19.080
<v Speaker 1>the human form of The gene is apparently a nucleotide

0:28:19.240 --> 0:28:25.480
<v Speaker 1>polymorphism genotype called r S one, and in two thousand

0:28:25.560 --> 0:28:29.160
<v Speaker 1>and nineteen, researchers from Canada, the US, and the UK

0:28:29.280 --> 0:28:32.439
<v Speaker 1>this would be struck at all um. They experimented with

0:28:32.480 --> 0:28:34.520
<v Speaker 1>it in a paper published in the Proceedings of the

0:28:34.560 --> 0:28:38.080
<v Speaker 1>National Academy of Science. The title is self regulation and

0:28:38.120 --> 0:28:41.640
<v Speaker 1>the foraging gene p r KG one in humans UH.

0:28:41.760 --> 0:28:45.320
<v Speaker 1>Here's how the study went down. So, the authors analyzed

0:28:45.360 --> 0:28:50.440
<v Speaker 1>the genotypes of rs and four thirty seven undergraduate students

0:28:50.600 --> 0:28:54.920
<v Speaker 1>who performed two virtual foraging tasks. So this was a

0:28:54.960 --> 0:28:58.720
<v Speaker 1>touch screen situation in which subjects search for and collected

0:28:58.960 --> 0:29:01.920
<v Speaker 1>as many red bear areas as possible within five minutes.

0:29:02.320 --> 0:29:05.320
<v Speaker 1>And then so they compared the subjects with C A

0:29:05.560 --> 0:29:10.360
<v Speaker 1>or CC genotypes of rs UH. Individuals with the A

0:29:10.360 --> 0:29:13.680
<v Speaker 1>A genotype were more likely to hug the boundary of

0:29:13.720 --> 0:29:17.640
<v Speaker 1>the search environment, pick smaller berries, and stop to pick

0:29:17.680 --> 0:29:21.240
<v Speaker 1>berries and patches with fewer visible berries a k A

0:29:21.320 --> 0:29:25.160
<v Speaker 1>sitter behavior. The findings suggests that the A A genotype

0:29:25.200 --> 0:29:29.520
<v Speaker 1>is associated with a search strategy that restricts exploration and

0:29:29.560 --> 0:29:33.920
<v Speaker 1>exploits the local environment extensively. In other words, distinct patterns

0:29:33.960 --> 0:29:38.520
<v Speaker 1>of goal pursuit for foraging are associated with particular genotypes

0:29:38.720 --> 0:29:42.040
<v Speaker 1>of pr k G one. That's very interesting. Now, as

0:29:42.040 --> 0:29:44.040
<v Speaker 1>we've talked about on the show before, you always have

0:29:44.080 --> 0:29:48.760
<v Speaker 1>to remember when you're drawing correlations between particular gene variants

0:29:48.760 --> 0:29:51.440
<v Speaker 1>and a behavior, it's it's almost never going to be

0:29:51.600 --> 0:29:53.560
<v Speaker 1>like an on off switch that like, if you have

0:29:53.640 --> 0:29:56.400
<v Speaker 1>a certain gene variant, you show X behavior and if

0:29:56.400 --> 0:29:58.880
<v Speaker 1>you don't have it, you don't. But instead you you'd

0:29:58.880 --> 0:30:02.200
<v Speaker 1>be charting sort of like you know, percentages of influence.

0:30:02.240 --> 0:30:05.360
<v Speaker 1>Can can you see correlations between gene variants and a

0:30:05.480 --> 0:30:08.680
<v Speaker 1>and a tendency or a certain proclivity to a certain

0:30:08.720 --> 0:30:11.680
<v Speaker 1>type of behavior and uh and so yeah, this would

0:30:11.720 --> 0:30:16.320
<v Speaker 1>say that somehow foraging behaviors or downstream from things that

0:30:16.400 --> 0:30:19.240
<v Speaker 1>this gene does to the brain that make you more

0:30:19.320 --> 0:30:21.960
<v Speaker 1>likely to kind of like go out on a long

0:30:22.040 --> 0:30:25.600
<v Speaker 1>search of versus try to exploit all of the resources

0:30:25.640 --> 0:30:29.560
<v Speaker 1>you can in your nearest immediate environment. Yeah. Yeah, absolutely, Now,

0:30:29.640 --> 0:30:31.080
<v Speaker 1>and of course we also have to keep in mind

0:30:31.160 --> 0:30:33.880
<v Speaker 1>that the scope in the size of the study here,

0:30:33.920 --> 0:30:36.720
<v Speaker 1>but um, and also I should point that the authors

0:30:37.040 --> 0:30:40.800
<v Speaker 1>mentioned that the human foraging behavior is ultimately far more

0:30:40.840 --> 0:30:44.880
<v Speaker 1>complex than the the foraging behavior fruit flies, and instead

0:30:44.920 --> 0:30:48.760
<v Speaker 1>they're just being two distinct foraging strategies. It seems like

0:30:48.800 --> 0:30:50.959
<v Speaker 1>they are three. So you have siderin rover, but then

0:30:51.000 --> 0:30:54.720
<v Speaker 1>you have a mixed uh disposition as well, the combines

0:30:54.760 --> 0:30:57.480
<v Speaker 1>elements of both. But on top of that, they point

0:30:57.480 --> 0:31:01.000
<v Speaker 1>out that this would go beyond mere foraging and humans,

0:31:01.040 --> 0:31:03.640
<v Speaker 1>that that it that it would instead impact human behavior

0:31:03.720 --> 0:31:07.600
<v Speaker 1>regulation across multiple domains. And I think we can imagine how, yeah,

0:31:07.640 --> 0:31:10.320
<v Speaker 1>that would involve various things that are like foraging, but

0:31:10.360 --> 0:31:16.360
<v Speaker 1>also potentially impact just sort of risk assessment, etcetera. Oh yeah,

0:31:16.400 --> 0:31:18.960
<v Speaker 1>I mean, I think it's easy to see how complex

0:31:19.040 --> 0:31:22.840
<v Speaker 1>modern behaviors are in a way kind of probably uh

0:31:23.280 --> 0:31:28.680
<v Speaker 1>minor reconfigurations of traditional instinctual behaviors like foraging, like hunting

0:31:28.760 --> 0:31:31.280
<v Speaker 1>and that kind of thing. Uh, So you can see

0:31:31.280 --> 0:31:34.840
<v Speaker 1>how whatever we're most instinctually inclined to do in terms

0:31:34.880 --> 0:31:37.760
<v Speaker 1>of foraging could manifest in the way you accomplish work

0:31:37.800 --> 0:31:40.840
<v Speaker 1>around the house, in the way that you know, go

0:31:41.000 --> 0:31:43.720
<v Speaker 1>shopping or whatever. I mean again, you you have to

0:31:43.760 --> 0:31:47.000
<v Speaker 1>be careful about drawing too direct and inference about anything

0:31:47.040 --> 0:31:50.320
<v Speaker 1>like that, but the fact that there's some kind of influences.

0:31:50.440 --> 0:31:53.200
<v Speaker 1>Seems pretty clear. All right, we're going to take a

0:31:53.240 --> 0:31:59.120
<v Speaker 1>quick break, but we'll be right back. Thank and we're

0:31:59.160 --> 0:32:02.959
<v Speaker 1>back now. Another aspect of early human foraging tactics, and

0:32:03.000 --> 0:32:06.200
<v Speaker 1>indeed the way these these early humans use spatial abilities

0:32:06.200 --> 0:32:09.320
<v Speaker 1>to gather resources, is that there was seemingly a division

0:32:09.360 --> 0:32:12.880
<v Speaker 1>of labor between males and females. This is the sexual

0:32:12.960 --> 0:32:17.280
<v Speaker 1>division of labor, sometimes abbreviated as sdl UM. And this

0:32:17.320 --> 0:32:19.000
<v Speaker 1>is a subject that has received a lot of study

0:32:19.040 --> 0:32:23.200
<v Speaker 1>over the years, especially of studies that look at extant

0:32:23.280 --> 0:32:26.520
<v Speaker 1>hunter gatherer populations in the world. And there are varying

0:32:26.640 --> 0:32:31.240
<v Speaker 1>hypotheses for the evolutionary origins of this divide. Now, for

0:32:31.280 --> 0:32:34.480
<v Speaker 1>our purposes here, I was looking at a study by

0:32:35.040 --> 0:32:43.000
<v Speaker 1>Louis Pacheco, Cobas, Marcos Rosetti, Cecilia Quanti Emquoees, and Robin

0:32:43.120 --> 0:32:47.840
<v Speaker 1>Hudson titled sex differences in mushroom gathering Men expend more

0:32:47.920 --> 0:32:51.400
<v Speaker 1>energy to obtain equivalent benefits and this was published in

0:32:51.560 --> 0:32:55.480
<v Speaker 1>Evolution and Human Behavior back in so the authors here

0:32:55.640 --> 0:32:58.600
<v Speaker 1>pointed out that the evidence was accumulating quote that women

0:32:58.600 --> 0:33:02.560
<v Speaker 1>excel on tasks appropriate it to gathering immobile plant resources

0:33:02.560 --> 0:33:07.080
<v Speaker 1>while men excel on task appropriate to hunting mobile, unpredictable prey.

0:33:07.160 --> 0:33:09.680
<v Speaker 1>And this would be due So the thinking goes to

0:33:09.800 --> 0:33:13.520
<v Speaker 1>this ancient labor divide in human societies. But it also

0:33:13.600 --> 0:33:17.480
<v Speaker 1>means that intrinsic foraging abilities and tactics would differ from

0:33:17.520 --> 0:33:20.480
<v Speaker 1>males to females. So the researchers here decided to put

0:33:20.520 --> 0:33:24.640
<v Speaker 1>this to the test with a mushroom foraging experiment, which

0:33:24.640 --> 0:33:26.560
<v Speaker 1>is the other key reason to discuss it here, because

0:33:26.720 --> 0:33:29.200
<v Speaker 1>people are are This is an experiment that includes not

0:33:29.320 --> 0:33:33.680
<v Speaker 1>touch screen um practices, not some sort of touch screen experiment,

0:33:33.760 --> 0:33:38.200
<v Speaker 1>but an actual foraging for mushrooms, let's forage. So in

0:33:38.280 --> 0:33:41.760
<v Speaker 1>their study they use GPS and heart rate monitors that

0:33:41.840 --> 0:33:45.640
<v Speaker 1>had been affixed to the researchers themselves, and then these

0:33:45.640 --> 0:33:48.800
<v Speaker 1>researchers would follow twenty one pairs of men and women

0:33:49.000 --> 0:33:53.600
<v Speaker 1>from an indigenous Mexican community in uh Tlex Cola while

0:33:53.680 --> 0:33:56.719
<v Speaker 1>foraging for mushrooms in the wild. So the researchers are

0:33:56.720 --> 0:33:59.920
<v Speaker 1>the ones where in the gear they're following the actual foragers,

0:34:00.320 --> 0:34:01.720
<v Speaker 1>but in doing so, they're going to be able to

0:34:01.800 --> 0:34:05.360
<v Speaker 1>chart where the foragers went and how much energy seems

0:34:05.400 --> 0:34:10.080
<v Speaker 1>to be expended in the silent hunt, so they ultimately

0:34:10.080 --> 0:34:13.600
<v Speaker 1>measured the costs, the benefits, and the general search efficiency

0:34:13.800 --> 0:34:17.759
<v Speaker 1>of everyone's movements, and then they analyzed them. The resulting

0:34:17.840 --> 0:34:21.440
<v Speaker 1>foraging patterns showed that while males and females collected similar

0:34:21.560 --> 0:34:26.400
<v Speaker 1>quantities of mushrooms, males achieved this at a significantly higher cost.

0:34:26.680 --> 0:34:29.719
<v Speaker 1>So the males they traveled farther. The males climbed to

0:34:29.960 --> 0:34:34.240
<v Speaker 1>greater altitudes. They had higher mean heart rates and energy

0:34:34.280 --> 0:34:38.640
<v Speaker 1>expenditures while partaking in the foraging, and in addition, they

0:34:38.680 --> 0:34:43.520
<v Speaker 1>also collected fewer mushroom species and visited fewer collection sites.

0:34:43.600 --> 0:34:46.600
<v Speaker 1>And this is interesting. They seemed to focus on large

0:34:46.640 --> 0:34:50.040
<v Speaker 1>patches of mushrooms, even if these were harder to come by,

0:34:50.120 --> 0:34:52.600
<v Speaker 1>so they were like bypassing or not even looking for

0:34:52.640 --> 0:34:55.239
<v Speaker 1>those smaller patches they wanted wanted to get the big

0:34:55.280 --> 0:35:00.080
<v Speaker 1>game mushroom patches. The females, meanwhile, it seemed to know

0:35:00.200 --> 0:35:03.760
<v Speaker 1>where to go and they foraged of from many small

0:35:03.800 --> 0:35:06.480
<v Speaker 1>patches as opposed to seeking out those greater patches of

0:35:06.520 --> 0:35:09.120
<v Speaker 1>fun guy. This was also compared by the way to

0:35:09.200 --> 0:35:13.200
<v Speaker 1>previous research on the way males and females navigate, which

0:35:13.200 --> 0:35:16.200
<v Speaker 1>indicated that males tend to create mental maps and then

0:35:16.239 --> 0:35:20.680
<v Speaker 1>superimpose their position, while women tend to remember landmarks and

0:35:20.760 --> 0:35:25.440
<v Speaker 1>memorize the routes quote. These findings are consistent with arguments

0:35:25.440 --> 0:35:28.040
<v Speaker 1>in the literature that differences in spatial ability between the

0:35:28.080 --> 0:35:31.399
<v Speaker 1>sexes are domain dependent, with women performing better and more

0:35:31.440 --> 0:35:35.200
<v Speaker 1>readily adopting search strategies appropriate to a gathering lifestyle than men.

0:35:35.960 --> 0:35:39.279
<v Speaker 1>So basically, the idea is that if you were primarily

0:35:39.360 --> 0:35:41.919
<v Speaker 1>charged with hunting prey two point five million years ago,

0:35:42.320 --> 0:35:46.200
<v Speaker 1>it made sense to travel far, to take widening paths

0:35:46.239 --> 0:35:49.840
<v Speaker 1>in pursuit of that big payoff prey, and then take

0:35:50.000 --> 0:35:53.160
<v Speaker 1>the shortest, most direct path back home so as to

0:35:53.239 --> 0:35:55.600
<v Speaker 1>make for up for all that time you spent wandering

0:35:55.640 --> 0:35:59.560
<v Speaker 1>and pursuing the prey. Meanwhile, if you were tasked with

0:35:59.560 --> 0:36:03.879
<v Speaker 1>gathering fungi or plants, it would serve to remember where

0:36:03.880 --> 0:36:06.840
<v Speaker 1>the most productive plant food sources were found, you know,

0:36:06.880 --> 0:36:10.799
<v Speaker 1>those honey spots, and then retrace your steps exactly so

0:36:10.880 --> 0:36:13.239
<v Speaker 1>as to take advantage of them in the future. And like, no,

0:36:13.360 --> 0:36:17.799
<v Speaker 1>making a bee line back for camp. That's very interesting. Uh. Now,

0:36:17.880 --> 0:36:19.960
<v Speaker 1>one thing that we always got to say whenever you

0:36:20.040 --> 0:36:23.240
<v Speaker 1>talk about studies that explore sex differences, is that people

0:36:23.600 --> 0:36:25.600
<v Speaker 1>a lot of people like to take these and really

0:36:25.680 --> 0:36:28.200
<v Speaker 1>run with them and say like, oh, this means that

0:36:28.320 --> 0:36:31.480
<v Speaker 1>men are like this and women are like that. I

0:36:31.480 --> 0:36:34.120
<v Speaker 1>think we always try to caution people not to not

0:36:34.200 --> 0:36:38.680
<v Speaker 1>to over interpret findings of sex differences in in particular studies.

0:36:39.280 --> 0:36:42.319
<v Speaker 1>It's very easy, I think, just because people want to

0:36:42.400 --> 0:36:46.160
<v Speaker 1>have strong intuitions about gender and sex and like what

0:36:46.239 --> 0:36:48.200
<v Speaker 1>men are like and what women are like and stuff

0:36:48.239 --> 0:36:51.239
<v Speaker 1>that they want to say like, oh, this explains why

0:36:51.360 --> 0:36:54.279
<v Speaker 1>my husband does this or why my girlfriend says that

0:36:54.360 --> 0:36:57.040
<v Speaker 1>kind of thing. You can you can easily go way

0:36:57.120 --> 0:37:00.920
<v Speaker 1>overboard with with looking for explanations in that way. Yeah.

0:37:00.960 --> 0:37:02.319
<v Speaker 1>I mean it also it comes down to what is

0:37:02.360 --> 0:37:06.120
<v Speaker 1>the Barnum effect that we've discussed before, where we say, oh, well,

0:37:06.160 --> 0:37:08.799
<v Speaker 1>that's me, this this study is correct because that's me.

0:37:09.320 --> 0:37:11.160
<v Speaker 1>I totally am like that when I go to the

0:37:11.480 --> 0:37:14.520
<v Speaker 1>to the grocery store and my my partner is like this, etcetera.

0:37:14.920 --> 0:37:17.480
<v Speaker 1>But but yeah, like you're saying, like, we're talking about

0:37:18.239 --> 0:37:22.319
<v Speaker 1>general perceived trends in the sexual division of labor and

0:37:22.400 --> 0:37:26.960
<v Speaker 1>as reflected here in particular studies. Uh so, yeah, I

0:37:27.040 --> 0:37:29.400
<v Speaker 1>don't don't have it printed on a T shirt or anything,

0:37:29.480 --> 0:37:32.759
<v Speaker 1>but but it is interesting research and and certainly it

0:37:32.840 --> 0:37:35.360
<v Speaker 1>was neat to find a study that was that was

0:37:35.440 --> 0:37:40.600
<v Speaker 1>actually involving mushroom foraging, like the scientific study of mushroom

0:37:40.640 --> 0:37:43.319
<v Speaker 1>foraging behavior totally, and it highlights how there can be

0:37:43.360 --> 0:37:46.640
<v Speaker 1>different types of foraging strategies that are effective in different ways.

0:37:46.680 --> 0:37:49.160
<v Speaker 1>I was looking at some other studies that were about

0:37:49.200 --> 0:37:52.360
<v Speaker 1>different types of foraging strategies and birds, you know, and

0:37:52.400 --> 0:37:55.120
<v Speaker 1>how this is kind of interesting, like some birds tend

0:37:55.160 --> 0:37:58.640
<v Speaker 1>to forage by moving in little random types of motions

0:37:58.680 --> 0:38:01.440
<v Speaker 1>around a central locust, uh in a way that's very

0:38:01.440 --> 0:38:05.160
<v Speaker 1>comparable actually to the movement of tiny particles on the

0:38:05.200 --> 0:38:08.360
<v Speaker 1>atomic scale that's known as Brownie in motion and physics.

0:38:08.840 --> 0:38:12.360
<v Speaker 1>Whereas other birds tended to forage by sort of taking

0:38:12.560 --> 0:38:16.239
<v Speaker 1>large leaps at a time. And that these, uh, these

0:38:16.280 --> 0:38:19.840
<v Speaker 1>different strategies could be differentially effective depending on what types

0:38:19.920 --> 0:38:23.360
<v Speaker 1>of things you're looking for while foraging, what the surrounding

0:38:23.480 --> 0:38:26.279
<v Speaker 1>landscape is, and things like that. Yeah, it's such a

0:38:26.320 --> 0:38:29.040
<v Speaker 1>foraging itself is just such a fascinating thing to think

0:38:29.040 --> 0:38:31.600
<v Speaker 1>about because it's easy to just sort of dismiss it

0:38:31.640 --> 0:38:34.240
<v Speaker 1>as this kind of primal thing that we sometimes engage

0:38:34.280 --> 0:38:36.200
<v Speaker 1>in when we decided to go into the woods and

0:38:36.200 --> 0:38:40.480
<v Speaker 1>look for mushrooms, etcetera. But it is again something basic

0:38:40.640 --> 0:38:44.080
<v Speaker 1>like neural activity that we're continually engaging in and and

0:38:44.160 --> 0:38:46.440
<v Speaker 1>something that also comes down to this kind of like

0:38:46.440 --> 0:38:48.960
<v Speaker 1>like this the basic mathematics of it, like how do

0:38:49.040 --> 0:38:52.440
<v Speaker 1>you go about looking for resources in a given area?

0:38:52.480 --> 0:38:54.040
<v Speaker 1>And then how are you how do you deal with

0:38:54.080 --> 0:38:57.000
<v Speaker 1>spatial awareness in that given area? Like there it seems

0:38:57.040 --> 0:39:00.239
<v Speaker 1>like a rich domain for you know, AI research in

0:39:00.239 --> 0:39:04.160
<v Speaker 1>the like totally because strangely enough, I feel like search

0:39:04.880 --> 0:39:09.440
<v Speaker 1>activities are one of the ways in which human behavior

0:39:09.480 --> 0:39:14.440
<v Speaker 1>can be most closely compared to what computer programs do.

0:39:14.440 --> 0:39:17.920
<v Speaker 1>Does that make sense? Yeah, that there are some pretty

0:39:17.960 --> 0:39:22.600
<v Speaker 1>direct analogies actually having to do with energy is expended

0:39:22.640 --> 0:39:29.600
<v Speaker 1>and efficiency in different ways of searching through randomly organized material. Yeah, yeah, absolutely.

0:39:29.640 --> 0:39:31.240
<v Speaker 1>I mean in the same way that you can imagine

0:39:31.280 --> 0:39:35.560
<v Speaker 1>someone in desiring an AI program that will find you

0:39:35.560 --> 0:39:37.840
<v Speaker 1>a good deal on something. There are also plenty of

0:39:37.920 --> 0:39:39.920
<v Speaker 1>humans out there like that's their thing, like let me,

0:39:40.000 --> 0:39:41.560
<v Speaker 1>let me help you find a good deal on that.

0:39:41.600 --> 0:39:44.319
<v Speaker 1>Because I love looking for him, So, yeah, I mean

0:39:44.560 --> 0:39:47.120
<v Speaker 1>a lot of it does come back to foraging. I

0:39:47.160 --> 0:39:50.880
<v Speaker 1>mean I would be interested in studies looking at foraging

0:39:50.960 --> 0:39:55.280
<v Speaker 1>behaviors in humans and animals compared to what search engines

0:39:55.320 --> 0:39:58.160
<v Speaker 1>do to get you your results. That would be interesting.

0:39:58.200 --> 0:40:02.360
<v Speaker 1>So who knows, perhaps will have some additional foraging episodes

0:40:02.480 --> 0:40:04.680
<v Speaker 1>in the future, as as you and I go out

0:40:04.719 --> 0:40:11.760
<v Speaker 1>into the wilds seeking out fruitful papers on these topics.

0:40:12.040 --> 0:40:14.360
<v Speaker 1>Bring it on home, all right, We're gonna have to

0:40:14.440 --> 0:40:17.200
<v Speaker 1>call it there. Uh. Likewise, we weren't able to touch

0:40:17.239 --> 0:40:21.399
<v Speaker 1>on everything regarding mushroom foraging and foraging related topics here,

0:40:21.520 --> 0:40:24.040
<v Speaker 1>but we certainly would love to hear from everyone out there. Um,

0:40:24.239 --> 0:40:26.880
<v Speaker 1>you know, are you involved in in mushroom foraging? Are

0:40:26.920 --> 0:40:30.719
<v Speaker 1>you an active forager? Or let us know your experiences.

0:40:30.760 --> 0:40:33.680
<v Speaker 1>We'd love to hear your insight on all of this. Likewise,

0:40:33.719 --> 0:40:36.720
<v Speaker 1>if you were, if your culture of origin, or you're

0:40:36.760 --> 0:40:39.560
<v Speaker 1>you know, if you're immersed in a particular cultural uh

0:40:39.719 --> 0:40:43.160
<v Speaker 1>take on mushroom foraging, be it you know, the activities

0:40:43.320 --> 0:40:47.000
<v Speaker 1>or or beliefs and strategies tied up with the foraging

0:40:47.160 --> 0:40:50.840
<v Speaker 1>uh activity, let us know. We'd love to be enlightened

0:40:50.840 --> 0:40:53.960
<v Speaker 1>on those topics, huge things. As always to our excellent
