WEBVTT - Mushroom Foraging, Part 2

0:00:03.040 --> 0:00:05.280
<v Speaker 1>Welcome to Stuff to Blow Your Mind, the production of

0:00:05.360 --> 0:00:14.640
<v Speaker 1>My Heart Radio. Hey, welcome to Stuff to Blow your Mind.

0:00:14.720 --> 0:00:17.279
<v Speaker 1>My name is Robert Lamb and I'm Joe McCormick. And

0:00:17.360 --> 0:00:20.720
<v Speaker 1>it's part two of Mushroom Foraging. We we started going

0:00:20.800 --> 0:00:24.000
<v Speaker 1>into the woods and we got lost, and uh, so

0:00:24.040 --> 0:00:25.680
<v Speaker 1>we had to we had to say, you know what,

0:00:25.760 --> 0:00:28.080
<v Speaker 1>this is actually two episodes. Here we are again with

0:00:28.160 --> 0:00:31.000
<v Speaker 1>part two. All right, let's jump right in. So we

0:00:31.040 --> 0:00:33.640
<v Speaker 1>already talked about how mushroom hunting appears to be this

0:00:33.760 --> 0:00:37.040
<v Speaker 1>really popular activity in Russia, and this goes way back,

0:00:37.080 --> 0:00:39.840
<v Speaker 1>and it's so popular that there are these common media

0:00:39.920 --> 0:00:42.680
<v Speaker 1>stories about people getting lost in the wilderness because they

0:00:42.680 --> 0:00:44.960
<v Speaker 1>went into a trance while mushroom hunting and then they

0:00:44.960 --> 0:00:48.640
<v Speaker 1>couldn't find their way home. But apparently things are very

0:00:48.680 --> 0:00:52.479
<v Speaker 1>similar in Poland. It's also a very common activity to

0:00:52.520 --> 0:00:56.560
<v Speaker 1>go mushroom hunting in Poland. And uh. The Polish romantic

0:00:56.640 --> 0:01:01.800
<v Speaker 1>poet Adam Mitskevitch, who lived from seven to eighteen fifty five,

0:01:02.320 --> 0:01:07.160
<v Speaker 1>wrote famously about mushroom foraging in his epic poem Panta Days.

0:01:07.880 --> 0:01:10.400
<v Speaker 1>And so I was looking at this in a few

0:01:10.400 --> 0:01:14.440
<v Speaker 1>different translations. I think the clearest one unfortunately doesn't go

0:01:14.560 --> 0:01:16.560
<v Speaker 1>for the whole poetry and meter of it. It's a

0:01:16.600 --> 0:01:20.520
<v Speaker 1>prose translation by George Rapaul Noyus, but I think this

0:01:20.560 --> 0:01:23.640
<v Speaker 1>will give the best sense of the passage, maybe losing

0:01:23.680 --> 0:01:27.080
<v Speaker 1>a bit of the music. Are you ready, Robert, Okay.

0:01:27.720 --> 0:01:30.480
<v Speaker 1>So there are these characters who are The basic drama

0:01:30.480 --> 0:01:34.920
<v Speaker 1>of Pantadash is about this conflict between these clans over

0:01:34.959 --> 0:01:37.240
<v Speaker 1>some kind of real estate dispute. I've never read the

0:01:37.240 --> 0:01:39.320
<v Speaker 1>whole thing, but I like the parts I have read.

0:01:39.360 --> 0:01:41.560
<v Speaker 1>And and so it's got all these, uh, these fancy

0:01:41.959 --> 0:01:45.520
<v Speaker 1>ladies and lads going out to hunt for mushrooms in

0:01:45.560 --> 0:01:48.440
<v Speaker 1>the forest, and they've announced that, you know, whichever lad

0:01:48.520 --> 0:01:51.440
<v Speaker 1>finds the fanciest mushroom will get to sit next to

0:01:51.480 --> 0:01:53.920
<v Speaker 1>the prettiest girl in the castle. And it's that kind

0:01:53.960 --> 0:01:57.320
<v Speaker 1>of thing. Uh. And so it goes into the section

0:01:57.360 --> 0:02:01.680
<v Speaker 1>on mushrooms. Quote of mushrooms, there were plenty. The lads

0:02:01.720 --> 0:02:05.520
<v Speaker 1>gathered the fair cheeked fox mushrooms, so famous in the

0:02:05.560 --> 0:02:09.520
<v Speaker 1>Lithuanian songs as the emblem of maidenhood. For the worms

0:02:09.680 --> 0:02:13.640
<v Speaker 1>do not eat them, and marvelous to say no insect

0:02:13.680 --> 0:02:17.240
<v Speaker 1>alights on them. The young ladies hunted for the slender

0:02:17.360 --> 0:02:21.440
<v Speaker 1>pine lover, which the song calls the kernel of the mushrooms.

0:02:21.440 --> 0:02:24.400
<v Speaker 1>And that's colonel, like the military rank, not like the popcorn.

0:02:25.200 --> 0:02:27.639
<v Speaker 1>I don't know why it wouldn't be the general of mushrooms.

0:02:27.680 --> 0:02:33.040
<v Speaker 1>But moving on, all were eager for the orange agaric. This,

0:02:33.280 --> 0:02:36.480
<v Speaker 1>though of more modest stature and less famous in song,

0:02:36.960 --> 0:02:40.680
<v Speaker 1>is still the most delicious, whether fresh or salted, whether

0:02:40.760 --> 0:02:45.800
<v Speaker 1>in autumn or in winter. But the sineschal gathered the toadstool, flybane,

0:02:46.240 --> 0:02:49.800
<v Speaker 1>the remainder of the mushroom family, are despised because they

0:02:49.840 --> 0:02:53.920
<v Speaker 1>are injurious or of poor flavor, but they are not useless.

0:02:54.400 --> 0:02:57.680
<v Speaker 1>They give food to beasts and shelter to insects, and

0:02:57.720 --> 0:03:01.080
<v Speaker 1>are an ornament to the groves. On the green cloth

0:03:01.200 --> 0:03:04.720
<v Speaker 1>of the meadows, they rise up like lines of table dishes.

0:03:05.360 --> 0:03:09.240
<v Speaker 1>Here are the leaf mushrooms, with their rounded borders, silver,

0:03:09.560 --> 0:03:13.480
<v Speaker 1>yellow and red, like little glasses filled with various sorts

0:03:13.480 --> 0:03:17.120
<v Speaker 1>of wine. The cos lac like the bulging bottom of

0:03:17.160 --> 0:03:22.520
<v Speaker 1>an upturned cup, the funnels like slender champagne glasses, the

0:03:22.720 --> 0:03:27.560
<v Speaker 1>round white, broad, flat white ease like china coffee cups

0:03:27.560 --> 0:03:30.920
<v Speaker 1>filled with milk, and the round puff ball filled with

0:03:30.960 --> 0:03:34.800
<v Speaker 1>a blackish dust like a pepper shaker. The names of

0:03:34.840 --> 0:03:37.600
<v Speaker 1>the others are known only in the language of hairs

0:03:37.760 --> 0:03:41.200
<v Speaker 1>or wolves by men. They have not been christened, but

0:03:41.280 --> 0:03:45.040
<v Speaker 1>they are innumerable. No one deigns to touch the wolf

0:03:45.160 --> 0:03:48.760
<v Speaker 1>or hair varieties, but whenever a person bends down to them,

0:03:49.040 --> 0:03:53.120
<v Speaker 1>he straight away perceives his mistake, grows angry, and breaks

0:03:53.160 --> 0:03:55.960
<v Speaker 1>the mushroom or kicks it with his foot, in thus

0:03:56.000 --> 0:04:01.560
<v Speaker 1>defiling the grass. He acts with great indiscretion. I like

0:04:01.640 --> 0:04:03.520
<v Speaker 1>at the end there it gets a little bit offended

0:04:03.560 --> 0:04:05.400
<v Speaker 1>on behalf of the grass. I guess I'm not sure

0:04:05.560 --> 0:04:08.760
<v Speaker 1>I fully understand the meaning of that last statement, but

0:04:08.800 --> 0:04:10.360
<v Speaker 1>I wanted to look at a couple of things about

0:04:10.400 --> 0:04:13.640
<v Speaker 1>this passage um So. One is that, first, while while

0:04:13.720 --> 0:04:17.640
<v Speaker 1>Russian and Polish cultures are considered to have a great

0:04:17.680 --> 0:04:22.120
<v Speaker 1>affinity for mushrooms, making them generally micophilic in some terminology

0:04:22.160 --> 0:04:25.520
<v Speaker 1>that will address a little bit later in the episode, uh,

0:04:25.560 --> 0:04:29.400
<v Speaker 1>this doesn't, of course manifest as a love for all

0:04:29.640 --> 0:04:33.839
<v Speaker 1>mushrooms unqualified. Instead, it seems to me that the mushroom

0:04:33.920 --> 0:04:38.919
<v Speaker 1>loving culture actually has a highly discriminating eye from mushrooms

0:04:38.960 --> 0:04:42.800
<v Speaker 1>noticing much more the important and perhaps life saving differences

0:04:42.880 --> 0:04:47.880
<v Speaker 1>between varieties. So like a mushroom culture doesn't just love mushrooms.

0:04:47.920 --> 0:04:50.560
<v Speaker 1>It's more like they really love the good ones and

0:04:50.680 --> 0:04:54.720
<v Speaker 1>really hate the bad ones. But of course, plenty of

0:04:54.800 --> 0:04:58.560
<v Speaker 1>mushroom hunting and accidental mushroom poisoning happens even in the

0:04:58.600 --> 0:05:02.040
<v Speaker 1>modern era. In Poland, was looking at a scientific report

0:05:02.080 --> 0:05:05.240
<v Speaker 1>compiling cases of mushroom poisoning in Poland from the year's

0:05:05.320 --> 0:05:09.000
<v Speaker 1>nineteen sixty two to nineteen sixty seven by an author

0:05:09.080 --> 0:05:13.880
<v Speaker 1>named Eliza Lewandowska. And this was called Mushroom Poisoning in

0:05:13.880 --> 0:05:16.160
<v Speaker 1>Poland in the years in nineteen sixty two to sixty

0:05:16.160 --> 0:05:20.440
<v Speaker 1>seven species of poisonous fungi. Now, there's no surprise at

0:05:20.480 --> 0:05:24.400
<v Speaker 1>all here that the species representing the most danger was

0:05:24.560 --> 0:05:28.760
<v Speaker 1>our old friend amanda felloids or the death cap mushroom.

0:05:28.800 --> 0:05:32.159
<v Speaker 1>We we've talked about this already, right, yes, now, this

0:05:32.200 --> 0:05:35.240
<v Speaker 1>one was responsible for at least four hundred and sixty

0:05:35.279 --> 0:05:37.880
<v Speaker 1>one cases of poisoning and a hundred and twenty six

0:05:37.920 --> 0:05:41.160
<v Speaker 1>deaths by this survey. A commonly cited figure that I've

0:05:41.160 --> 0:05:44.640
<v Speaker 1>seen elsewhere is that death caps today represent more than

0:05:44.800 --> 0:05:48.719
<v Speaker 1>nine of fatal mushroom poisonings worldwide. So so they're the

0:05:48.760 --> 0:05:53.640
<v Speaker 1>real bad boy in terms of accidental accidental mushroom poisoning. UM.

0:05:53.720 --> 0:05:57.039
<v Speaker 1>But I was also reading about how the specific way

0:05:57.360 --> 0:06:02.440
<v Speaker 1>that Amanda philoids kills is deceptive lee devious. So when

0:06:02.440 --> 0:06:06.240
<v Speaker 1>somebody eats this mushroom, it's not necessarily what you would

0:06:06.240 --> 0:06:08.760
<v Speaker 1>picture where you eat it and then you're immediately doubled

0:06:08.800 --> 0:06:12.200
<v Speaker 1>over in pain and you know, and hallucinating and sweating

0:06:12.240 --> 0:06:15.520
<v Speaker 1>with a fever and screaming. Instead, when somebody eats the

0:06:15.839 --> 0:06:19.720
<v Speaker 1>Amanda floid e is it doesn't necessarily cause any immediate

0:06:19.720 --> 0:06:23.200
<v Speaker 1>pain or discomfort. In fact, people often don't have any

0:06:23.240 --> 0:06:26.520
<v Speaker 1>symptoms at all for many hours I've read, sometimes maybe

0:06:26.560 --> 0:06:29.240
<v Speaker 1>six hours later, sometimes even not until like a full

0:06:29.360 --> 0:06:33.680
<v Speaker 1>day later, and then the cramps and the nausea and

0:06:33.720 --> 0:06:37.120
<v Speaker 1>the vomiting and the diarrhea set in. And I've read

0:06:37.120 --> 0:06:39.960
<v Speaker 1>that this can make it easy to mistake the poisoning

0:06:40.360 --> 0:06:42.640
<v Speaker 1>for something else. You might think you've got a stomach

0:06:42.680 --> 0:06:45.560
<v Speaker 1>bug or whatever, because of the length of time between

0:06:45.600 --> 0:06:48.880
<v Speaker 1>eating the mushroom and the onset of symptoms. And uh,

0:06:48.920 --> 0:06:51.520
<v Speaker 1>and at this point, after the symptoms set in, they

0:06:51.520 --> 0:06:55.200
<v Speaker 1>can sometimes even retreat, they can grow milder if the

0:06:55.200 --> 0:06:58.320
<v Speaker 1>patient is properly cared for, properly hydrated, and all that.

0:06:59.200 --> 0:07:01.560
<v Speaker 1>The entire time, I'm the amine to toxins are in

0:07:01.600 --> 0:07:05.240
<v Speaker 1>the background, just massacreing cells in the liver and harming

0:07:05.279 --> 0:07:09.559
<v Speaker 1>the kidneys, eventually leading to organ failure and eventually to death.

0:07:10.520 --> 0:07:13.240
<v Speaker 1>And I don't know that there's there's something kind of

0:07:14.360 --> 0:07:18.320
<v Speaker 1>especially terrifying about that that there's this You can have

0:07:18.360 --> 0:07:21.360
<v Speaker 1>this false sense that things are getting better and that oh,

0:07:21.400 --> 0:07:23.680
<v Speaker 1>I'm actually feeling a little bit better than i was earlier,

0:07:23.760 --> 0:07:26.040
<v Speaker 1>or maybe I'm not even feeling bad at all, while

0:07:26.160 --> 0:07:30.160
<v Speaker 1>the mushroom is actively killing your vital organs. I think

0:07:30.160 --> 0:07:33.880
<v Speaker 1>it also underlines just the sort of precision that had

0:07:33.920 --> 0:07:37.600
<v Speaker 1>to take place in figuring out the properties of various

0:07:37.720 --> 0:07:41.640
<v Speaker 1>mushrooms and and other organisms in one's environment, you know,

0:07:42.080 --> 0:07:45.320
<v Speaker 1>because this is clearly something where you you would have

0:07:45.400 --> 0:07:48.680
<v Speaker 1>to do a little detective work to figure out it. Yeah,

0:07:48.720 --> 0:07:53.880
<v Speaker 1>exactly what had caused this awful illness in the individual exactly.

0:07:54.200 --> 0:07:57.280
<v Speaker 1>But in in second place for poisonings was a species

0:07:57.320 --> 0:08:01.200
<v Speaker 1>that is also interesting and and requires are kind of precision,

0:08:01.320 --> 0:08:04.600
<v Speaker 1>but with a different difficulty I don't think we've talked

0:08:04.600 --> 0:08:07.240
<v Speaker 1>about this one yet. The second place in the Polish

0:08:07.280 --> 0:08:11.760
<v Speaker 1>survey for for most poisoning in death was gyrometra esculenta

0:08:11.920 --> 0:08:16.360
<v Speaker 1>or the false moral mushroom. Uh, that's moral like m

0:08:16.360 --> 0:08:19.560
<v Speaker 1>O R e L moral mushrooms not morals as you know,

0:08:20.320 --> 0:08:24.720
<v Speaker 1>doing good. Yeah, and so in this survey, the false

0:08:24.800 --> 0:08:27.800
<v Speaker 1>moral was responsible for a hundred and sixty four cases

0:08:27.840 --> 0:08:31.960
<v Speaker 1>of poisoning and ten deaths in this time in the sixties. Now,

0:08:31.960 --> 0:08:35.480
<v Speaker 1>the false moral is a very strange and interesting case

0:08:35.520 --> 0:08:39.960
<v Speaker 1>study in fungal toxicity because, first of all, it looks crazy.

0:08:40.040 --> 0:08:41.920
<v Speaker 1>It looks like a brain on a stick, or not

0:08:41.960 --> 0:08:44.280
<v Speaker 1>even a normal brain. It looks like if you tried

0:08:44.360 --> 0:08:48.080
<v Speaker 1>to make a raisin out of a brain. Yeah, it

0:08:48.200 --> 0:08:52.120
<v Speaker 1>kind of looks like what you have mushroom but ground chuck.

0:08:52.320 --> 0:08:55.880
<v Speaker 1>You know. It of appearance, Yeah, it's got the little

0:08:56.160 --> 0:09:00.280
<v Speaker 1>grinder extrusion patterns. Yeah it does. It looks kind of

0:09:00.320 --> 0:09:02.000
<v Speaker 1>like it's come out of a machine in a way.

0:09:02.040 --> 0:09:04.840
<v Speaker 1>I agree, had an extruded kind of appearance to it.

0:09:05.280 --> 0:09:07.960
<v Speaker 1>But a lot of delicious mushrooms look very strange and

0:09:08.040 --> 0:09:12.599
<v Speaker 1>very unlike other foods we eat. So you know, that's fine, um.

0:09:12.760 --> 0:09:16.120
<v Speaker 1>But but gyrometra is an interesting case because the toxicity

0:09:16.160 --> 0:09:19.280
<v Speaker 1>seems to vary a lot. Just one example I was

0:09:19.320 --> 0:09:23.840
<v Speaker 1>reading in a stat Pearls entry by Horowitz, Kong and Horowitz,

0:09:23.880 --> 0:09:28.440
<v Speaker 1>and the author's report quote most poisonings occur in Eastern Europe,

0:09:28.520 --> 0:09:32.520
<v Speaker 1>particularly in the conifer forests of Germany, Poland, and Finland.

0:09:32.920 --> 0:09:37.320
<v Speaker 1>In North America, most exposures occur in Michigan, although a

0:09:37.400 --> 0:09:40.520
<v Speaker 1>less toxic variety grows west of the Rockies and has

0:09:40.559 --> 0:09:44.960
<v Speaker 1>been clustered in Idaho and Western Canada. Exposures occur mostly

0:09:45.000 --> 0:09:48.800
<v Speaker 1>in the spring, unlike other serious mushroom poisonings such as

0:09:48.840 --> 0:09:53.400
<v Speaker 1>Amanda filoids, which occur more commonly in the fall. So

0:09:53.679 --> 0:09:56.880
<v Speaker 1>there's this geographical distribution. I've read about how there are

0:09:56.960 --> 0:10:00.320
<v Speaker 1>different rates of poisoning from the false morale to ending

0:10:00.360 --> 0:10:03.320
<v Speaker 1>on where the mushroom was grown, you know, in in

0:10:03.400 --> 0:10:06.640
<v Speaker 1>different countries and at different altitudes and things like that.

0:10:06.679 --> 0:10:09.679
<v Speaker 1>It seems to vary a lot, depending on you know,

0:10:09.720 --> 0:10:13.920
<v Speaker 1>what local strain you're getting, and possibly due to interactions

0:10:13.920 --> 0:10:16.680
<v Speaker 1>with you know, with the body of the person who

0:10:16.679 --> 0:10:19.800
<v Speaker 1>eats it. Another thing I've read is that poisoning is

0:10:19.840 --> 0:10:23.840
<v Speaker 1>here are much more common when these mushrooms are eaten raw. Now,

0:10:24.120 --> 0:10:28.040
<v Speaker 1>there's one thing that poison control authorities often emphasize, which

0:10:28.080 --> 0:10:31.640
<v Speaker 1>is that you should not use intuitive smell and taste

0:10:31.640 --> 0:10:35.280
<v Speaker 1>senses to figure out what is poisonous in the mushroom world,

0:10:35.480 --> 0:10:38.760
<v Speaker 1>because even though our senses of smell and taste are

0:10:38.800 --> 0:10:41.960
<v Speaker 1>certainly evolved to help us figure out what's good to eat,

0:10:42.320 --> 0:10:46.240
<v Speaker 1>they are not an infallible guide. And a great example

0:10:46.320 --> 0:10:49.240
<v Speaker 1>of this is once again the deathcap mushroom, one of

0:10:49.280 --> 0:10:52.600
<v Speaker 1>the most dangerous mushrooms to humans and the most deadly

0:10:52.600 --> 0:10:54.720
<v Speaker 1>one in Poland. During that survey we were just talking

0:10:54.720 --> 0:10:58.720
<v Speaker 1>about the deathcap mushroom does not taste like poison. It

0:10:58.760 --> 0:11:02.400
<v Speaker 1>reportedly does not taste bitter, does not taste sour, does

0:11:02.440 --> 0:11:05.240
<v Speaker 1>not you know, set your mouth on fire with needles

0:11:05.240 --> 0:11:08.120
<v Speaker 1>going into your tongue. In fact, it is widely said

0:11:08.160 --> 0:11:12.160
<v Speaker 1>to be absolutely delicious. There are people who have had

0:11:12.200 --> 0:11:17.880
<v Speaker 1>these hepatotoxic mushrooms absolutely destroy their liver. But they report that,

0:11:18.000 --> 0:11:20.120
<v Speaker 1>you know, before the pain and the nausea set in

0:11:20.200 --> 0:11:23.040
<v Speaker 1>six hours later, twenty four hours later, when whenever it is,

0:11:23.280 --> 0:11:26.040
<v Speaker 1>while they're eating these mushrooms. They are some of the

0:11:26.080 --> 0:11:29.480
<v Speaker 1>best tasting mushrooms that they've ever had. Uh. They're said

0:11:29.520 --> 0:11:34.120
<v Speaker 1>to smell sweet like honey and taste absolutely delightful, sauteed

0:11:34.200 --> 0:11:37.360
<v Speaker 1>and buttered. Don't do this, don't It's not worth it.

0:11:37.360 --> 0:11:40.000
<v Speaker 1>It will kill you. Do not take the death cap

0:11:40.120 --> 0:11:42.800
<v Speaker 1>challenge if you see something like that on YouTube. No,

0:11:42.880 --> 0:11:45.720
<v Speaker 1>not at all. But but this does bring me back

0:11:45.720 --> 0:11:50.199
<v Speaker 1>to an interesting observation from Miskovich, which is that some

0:11:50.400 --> 0:11:54.000
<v Speaker 1>of the species of mushroom that are detestable to humankind,

0:11:54.040 --> 0:11:55.839
<v Speaker 1>and I'm sure the death cap is one of these

0:11:55.880 --> 0:11:59.839
<v Speaker 1>in in his survey, they're known in the cultures of

0:12:00.080 --> 0:12:02.400
<v Speaker 1>he calls the wolves or the hairs, you know, the

0:12:02.480 --> 0:12:05.760
<v Speaker 1>language of wolves or rabbits. Now, you might think that

0:12:05.800 --> 0:12:08.240
<v Speaker 1>this is just another folk tale about the animals of

0:12:08.240 --> 0:12:10.719
<v Speaker 1>the forest, but I think that this could actually be

0:12:10.760 --> 0:12:14.680
<v Speaker 1>based on real observation, because despite being one of the

0:12:14.720 --> 0:12:18.360
<v Speaker 1>most deadly fungi to humans, it is not necessarily deadly

0:12:18.440 --> 0:12:21.839
<v Speaker 1>to everything in the forest all of the time. It

0:12:21.920 --> 0:12:24.720
<v Speaker 1>came across one statement about this when I was reading

0:12:24.720 --> 0:12:28.720
<v Speaker 1>an article about the spread of the deathcap mushroom throughout

0:12:28.760 --> 0:12:31.959
<v Speaker 1>North America, and this was by Craig Childs in the Atlantic.

0:12:32.480 --> 0:12:35.680
<v Speaker 1>It's a very interesting article. It's worth reading. A Child's

0:12:35.840 --> 0:12:40.439
<v Speaker 1>talks about how deathcap mushrooms naturally live in a symbiotic

0:12:40.480 --> 0:12:43.480
<v Speaker 1>relationship with host trees. And we've talked about how several

0:12:43.559 --> 0:12:46.880
<v Speaker 1>mushroom species are like this. They attached themselves to the

0:12:46.960 --> 0:12:50.000
<v Speaker 1>roots of trees and they sort of trade resources between them,

0:12:50.640 --> 0:12:53.000
<v Speaker 1>uh and so that they're able to get some nutrition

0:12:53.080 --> 0:12:55.440
<v Speaker 1>from from tree roots. And this is the reason that

0:12:55.480 --> 0:12:57.680
<v Speaker 1>you will often find them sort of in a ring

0:12:57.840 --> 0:13:00.840
<v Speaker 1>of deadly fruiting bodies around the roots of a central

0:13:00.880 --> 0:13:05.240
<v Speaker 1>tree trunk. But their spores don't naturally tend to spread

0:13:05.360 --> 0:13:08.839
<v Speaker 1>very far, at least under normal circumstances, and it has

0:13:08.880 --> 0:13:14.439
<v Speaker 1>taken human intervention to really set them spreading far and wide. Specifically,

0:13:14.480 --> 0:13:17.439
<v Speaker 1>what's named by Craig Child's in this article is that

0:13:17.640 --> 0:13:23.160
<v Speaker 1>deathcap mushrooms have been spreaded, spreading rapidly throughout northwest North America,

0:13:23.760 --> 0:13:27.760
<v Speaker 1>riding along on the roots of imported European trees, like

0:13:27.880 --> 0:13:30.760
<v Speaker 1>imported sweet chestnut trees and beech trees. So you get

0:13:30.760 --> 0:13:34.120
<v Speaker 1>this fancy tree from Europe, it's got deathcap mushrooms in

0:13:34.120 --> 0:13:36.360
<v Speaker 1>a relationship with it. You bring the tree over here,

0:13:36.480 --> 0:13:40.920
<v Speaker 1>planted and it brings the poisonous mushrooms with it. But anyway,

0:13:41.480 --> 0:13:44.360
<v Speaker 1>the reason I brought this article up was that there's

0:13:44.400 --> 0:13:49.040
<v Speaker 1>this quick side note where Child's mentions that that squirrels

0:13:49.040 --> 0:13:53.040
<v Speaker 1>and rabbits have sometimes been observed to eat deathcap mushrooms

0:13:53.080 --> 0:13:56.400
<v Speaker 1>without being harmed at all, which sounds again like like

0:13:56.480 --> 0:13:59.760
<v Speaker 1>mits Kevich, like that, you know, the hairs don't really

0:13:59.800 --> 0:14:03.320
<v Speaker 1>mind in the mushrooms that the humans find absolutely detestable,

0:14:03.600 --> 0:14:06.200
<v Speaker 1>and so I think that's interesting. It's another indication of

0:14:06.200 --> 0:14:08.839
<v Speaker 1>what you should not do. You should not watch what

0:14:08.960 --> 0:14:11.760
<v Speaker 1>animals eat in the forest to determine what would be

0:14:11.760 --> 0:14:13.800
<v Speaker 1>okay for you to eat, because they may be able

0:14:13.840 --> 0:14:18.000
<v Speaker 1>to digest and metabolize stuff just fine that would absolutely

0:14:18.080 --> 0:14:21.120
<v Speaker 1>kill you with just a few mouthfuls. And also in

0:14:21.160 --> 0:14:26.520
<v Speaker 1>this just another reason to respect the mighty squirrel. Yes, yeah,

0:14:26.640 --> 0:14:28.640
<v Speaker 1>I saw squirrels were thrown in there too, So I'm

0:14:28.640 --> 0:14:32.120
<v Speaker 1>sure our fans are gonna gonna go hog wild about that.

0:14:33.120 --> 0:14:38.680
<v Speaker 1>Meme away, Yeah, meme until you drop. But one last

0:14:38.720 --> 0:14:40.720
<v Speaker 1>thing I wanted to add about this was I saw

0:14:40.760 --> 0:14:44.160
<v Speaker 1>some mushroom enthusiasts online just in comments sections and stuff,

0:14:44.400 --> 0:14:47.600
<v Speaker 1>saying that they kind of wish they had whatever resistance

0:14:47.720 --> 0:14:51.520
<v Speaker 1>these rabbits have to to the death cap toxicity is

0:14:51.600 --> 0:14:53.920
<v Speaker 1>because they would love to taste them, for one, since

0:14:54.000 --> 0:14:56.880
<v Speaker 1>you know, by all accounts, when people eat them, even

0:14:56.920 --> 0:15:01.720
<v Speaker 1>though it kills them, they are very tasty. Interesting. Um,

0:15:02.560 --> 0:15:05.480
<v Speaker 1>you know, in our previous episode we mentioned we mentioned

0:15:05.480 --> 0:15:08.960
<v Speaker 1>a few different mushroom foraging cultures, and I believe Scottish

0:15:09.320 --> 0:15:12.600
<v Speaker 1>culture came up. As luck would have it, was watching

0:15:12.800 --> 0:15:17.160
<v Speaker 1>hum the the TV adaptation of Outlander last night. Start

0:15:17.200 --> 0:15:19.840
<v Speaker 1>watching that, yeah, and in the second episode, what happens

0:15:19.880 --> 0:15:23.600
<v Speaker 1>they're forging for mushrooms, talking about them, the medicinal use

0:15:23.600 --> 0:15:26.000
<v Speaker 1>of mushrooms and which ones are good to eat and

0:15:26.040 --> 0:15:29.360
<v Speaker 1>which ones are poisonous. I found it rather interesting. Also

0:15:29.960 --> 0:15:32.760
<v Speaker 1>castle they used in that show, same castle they used

0:15:32.760 --> 0:15:36.080
<v Speaker 1>in Highlander, uh and in Monty Python and the Holy Grail.

0:15:36.080 --> 0:15:38.360
<v Speaker 1>So it's got that going for it. So even in

0:15:38.600 --> 0:15:41.640
<v Speaker 1>your ultimate kilt lift or narrative, you cannot escape a

0:15:41.640 --> 0:15:44.680
<v Speaker 1>good mushroom hunt, right, I mean that's I mean you've

0:15:44.680 --> 0:15:46.960
<v Speaker 1>got time travel in there, so it's uh, it's it's

0:15:47.000 --> 0:15:49.880
<v Speaker 1>a big part of the plot apparently, at least as

0:15:49.920 --> 0:15:52.720
<v Speaker 1>I can gather thus far well, whether you're time traveling

0:15:52.800 --> 0:15:55.200
<v Speaker 1>or not, whether you forage for mushrooms or not, stay

0:15:55.200 --> 0:15:57.640
<v Speaker 1>away from the death caps, just just don't even try

0:15:57.680 --> 0:15:59.840
<v Speaker 1>it now. Of course, this is this goes way back.

0:16:00.120 --> 0:16:04.000
<v Speaker 1>This this basic um reality that we're discussing here, and

0:16:04.040 --> 0:16:07.880
<v Speaker 1>we've we've covered humanities hunter gatherer past on the show before.

0:16:08.440 --> 0:16:10.880
<v Speaker 1>I mean, the basic is you know, we're we're omnivores,

0:16:11.120 --> 0:16:14.320
<v Speaker 1>and mushrooms have always been on the table. Uh. Though

0:16:14.320 --> 0:16:17.800
<v Speaker 1>of course our ancestors had to devise the expertise to

0:16:17.920 --> 0:16:21.200
<v Speaker 1>avoid harmful species as well as figuring out which ones

0:16:21.200 --> 0:16:25.320
<v Speaker 1>are beneficial, which ones can be food, etcetera. One of

0:16:25.320 --> 0:16:27.880
<v Speaker 1>the resources we were looking at for this section was

0:16:28.040 --> 0:16:32.120
<v Speaker 1>Eric BoA's Wild Edible Fungi a Global Overview of their

0:16:32.240 --> 0:16:34.920
<v Speaker 1>Use and Importance to People. Yeah, it looks like this

0:16:35.000 --> 0:16:38.239
<v Speaker 1>was a report compiled for the Food and Agriculture Organization

0:16:38.280 --> 0:16:41.480
<v Speaker 1>of the u N in two thousand four. Yeah, and uh,

0:16:41.520 --> 0:16:44.200
<v Speaker 1>and Boa points out, I'm gonna mention a few different

0:16:44.400 --> 0:16:46.880
<v Speaker 1>facts that points out here. First of all, wild edible

0:16:46.880 --> 0:16:49.800
<v Speaker 1>fungi are collected for food in more than eighty countries,

0:16:50.280 --> 0:16:53.440
<v Speaker 1>and we're dealing with more than one thousand, one hundred

0:16:53.520 --> 0:16:58.200
<v Speaker 1>species and interestingly enough, some cultures may be viewed is

0:16:58.440 --> 0:17:03.480
<v Speaker 1>microphobic being you know, meaning there's a fear of mushrooms

0:17:03.600 --> 0:17:07.360
<v Speaker 1>or a reluctance to engage in mushroom consumption and foraging,

0:17:07.640 --> 0:17:12.320
<v Speaker 1>while other cultures are are microphilic meaning you know, the

0:17:12.520 --> 0:17:15.439
<v Speaker 1>loving mushrooms, you know, being open to those experiences in

0:17:15.480 --> 0:17:19.199
<v Speaker 1>those quests, with English culture standing interestingly enough as an

0:17:19.200 --> 0:17:25.320
<v Speaker 1>example of microphobic UH culture, while Chinese culture, he mentions,

0:17:25.480 --> 0:17:29.040
<v Speaker 1>is a strongly micophilic culture. He points out that a

0:17:29.040 --> 0:17:32.200
<v Speaker 1>lot of Chinese writings on mushrooms have yet to be translated,

0:17:32.200 --> 0:17:34.359
<v Speaker 1>but there's a lot of material there. Now. I found

0:17:34.359 --> 0:17:38.120
<v Speaker 1>this very interesting because I've certainly seen some documentaries um

0:17:38.200 --> 0:17:42.240
<v Speaker 1>that really focus in on on British and Scottish traditions

0:17:42.240 --> 0:17:46.239
<v Speaker 1>regarding mushroom hunting. Yeah, and of course that highlights that

0:17:46.520 --> 0:17:49.520
<v Speaker 1>these designations. I've seen these designations used by other people

0:17:49.560 --> 0:17:52.520
<v Speaker 1>as well. Burtleston talks about this, where you know, cultures

0:17:52.520 --> 0:17:56.080
<v Speaker 1>that are predominantly microphobic or microphilic, they're all gonna be relative,

0:17:56.200 --> 0:17:58.880
<v Speaker 1>right Like, within each of these broad cultures, there will

0:17:58.880 --> 0:18:01.440
<v Speaker 1>be subcultures and then individuals that sort of run against

0:18:01.480 --> 0:18:05.359
<v Speaker 1>the grain. Um. But on the note of of of

0:18:05.480 --> 0:18:09.359
<v Speaker 1>Chinese culture being microphilic, of course that comes through in

0:18:09.359 --> 0:18:13.280
<v Speaker 1>in certain types of ancient medical practices, but also in cuisine.

0:18:13.520 --> 0:18:17.080
<v Speaker 1>And I just think about one of my earliest memories

0:18:17.080 --> 0:18:19.639
<v Speaker 1>of Chinese food. I've loved Chinese food as long as

0:18:19.640 --> 0:18:22.639
<v Speaker 1>I can remember, but one of my earliest memories is

0:18:22.800 --> 0:18:27.520
<v Speaker 1>of the unidentifiable fungus within the Chinese soup I was eating,

0:18:27.520 --> 0:18:30.760
<v Speaker 1>and how much I loved it, and how how it

0:18:30.880 --> 0:18:33.240
<v Speaker 1>was like there was nothing else like this in my diet.

0:18:33.280 --> 0:18:35.200
<v Speaker 1>I guess it was probably a type of black fungus

0:18:35.200 --> 0:18:37.920
<v Speaker 1>in a hot and sour soup, and I was just like,

0:18:38.000 --> 0:18:40.399
<v Speaker 1>what is this? I have no idea. It's like something

0:18:40.440 --> 0:18:45.320
<v Speaker 1>from another planet, and it's delicious. But as to microphobia,

0:18:45.320 --> 0:18:49.840
<v Speaker 1>Birtleson mentions evidence of strains of microphobic thinking in many

0:18:49.840 --> 0:18:53.320
<v Speaker 1>of the historic common names for mushrooms in some European cultures.

0:18:53.720 --> 0:18:56.280
<v Speaker 1>For example, though today we think of French cuisine as

0:18:56.359 --> 0:19:01.119
<v Speaker 1>being very very pro mushroom, historically there was some French

0:19:01.160 --> 0:19:05.679
<v Speaker 1>aversion to mushrooms, like calling mushrooms things like eggs of

0:19:05.720 --> 0:19:10.439
<v Speaker 1>the devil or the devil's paint brush, or toads bread.

0:19:11.240 --> 0:19:14.880
<v Speaker 1>Of course, there's the English expression toad stool. In Danish

0:19:14.880 --> 0:19:18.600
<v Speaker 1>and Norwegian you have variations on poda hot toad's hat,

0:19:19.320 --> 0:19:22.280
<v Speaker 1>and in Germanic and Celtic cultures. Burtleson writes that you

0:19:22.359 --> 0:19:26.960
<v Speaker 1>sometimes see an association between mushrooms and witchcraft, and this

0:19:27.000 --> 0:19:30.359
<v Speaker 1>association may have played a role in keeping the British

0:19:30.440 --> 0:19:35.359
<v Speaker 1>Aisles relatively microphobic for for many centuries. You know, I

0:19:35.400 --> 0:19:37.199
<v Speaker 1>can't help me be reminded. I'm sure I've brought this

0:19:37.280 --> 0:19:40.000
<v Speaker 1>up on the show before. Um, but there's that that

0:19:40.080 --> 0:19:43.399
<v Speaker 1>wonderful um a little bit in uh Burt of Eccos

0:19:43.440 --> 0:19:45.720
<v Speaker 1>the Name of the Rose, where there's the story of

0:19:45.720 --> 0:19:49.960
<v Speaker 1>of one monk. You know, it's like a multi multi cultural,

0:19:50.200 --> 0:19:54.119
<v Speaker 1>multi linguistic community of monks there, and one is talking

0:19:54.160 --> 0:19:57.240
<v Speaker 1>about having this pig that will accompany them into the

0:19:57.280 --> 0:20:01.960
<v Speaker 1>woods to search for truffles. And the other monk that's

0:20:01.960 --> 0:20:05.440
<v Speaker 1>hearing this story is I believe German, and he thinks

0:20:05.440 --> 0:20:08.040
<v Speaker 1>that he's not saying truffle but to full, which is

0:20:08.160 --> 0:20:10.520
<v Speaker 1>a German for devil, So he thinks this is a

0:20:10.520 --> 0:20:14.560
<v Speaker 1>horrific story of this weird pig that will accompany uh,

0:20:14.600 --> 0:20:17.040
<v Speaker 1>you into the woods so that you can seek out

0:20:17.080 --> 0:20:20.080
<v Speaker 1>the devil. I remember that moment, and that's oh man,

0:20:20.119 --> 0:20:22.600
<v Speaker 1>that's so emblematic of everything I love about Name of

0:20:22.600 --> 0:20:27.280
<v Speaker 1>the Rose. Now, in terms of the ancient uh uh

0:20:27.600 --> 0:20:30.320
<v Speaker 1>foraging for mushrooms and the use of mushrooms by by

0:20:30.400 --> 0:20:33.240
<v Speaker 1>human beings, you know, there's there's apparently evidence in what

0:20:33.359 --> 0:20:36.919
<v Speaker 1>is now Chile of mushroom consumption by humans thirteen thousand

0:20:37.040 --> 0:20:40.359
<v Speaker 1>years ago. Um Obso, the iceman who we've mentioned on

0:20:40.400 --> 0:20:44.840
<v Speaker 1>the show before, who lived between thirty four UM hundred

0:20:45.000 --> 0:20:47.960
<v Speaker 1>and thirty one b c uh somewhere in that area,

0:20:48.200 --> 0:20:51.080
<v Speaker 1>was found with two varieties of fun guy on his person,

0:20:51.560 --> 0:20:54.280
<v Speaker 1>one of which we've discussed on our other show or

0:20:54.359 --> 0:20:57.680
<v Speaker 1>previous other show. Invention was likely a dried fungi used

0:20:57.720 --> 0:20:59.960
<v Speaker 1>to help start fires, but the other was a bird

0:21:00.119 --> 0:21:04.040
<v Speaker 1>fungus that was likely consumed for medicinal reasons. And so

0:21:04.080 --> 0:21:07.120
<v Speaker 1>the consumption of mushrooms for culinary and or medicinal purposes

0:21:07.160 --> 0:21:09.920
<v Speaker 1>dates back in a number of ancient cultures. They're they're

0:21:09.960 --> 0:21:13.199
<v Speaker 1>more examples of this than we could easily cover on

0:21:13.240 --> 0:21:17.040
<v Speaker 1>the show here. Uh. And with the agricultural revolution came

0:21:17.080 --> 0:21:20.120
<v Speaker 1>the eventuality of mushroom cultivation as well. Though, as we've

0:21:20.160 --> 0:21:23.120
<v Speaker 1>previously touched on, there are so many varieties that are

0:21:23.160 --> 0:21:27.119
<v Speaker 1>resistant to cultivation. Yeah. I think specifically a lot of

0:21:27.119 --> 0:21:29.240
<v Speaker 1>the ones that you think of that are most commonly

0:21:29.320 --> 0:21:31.600
<v Speaker 1>used in food that are the hardest to cultivate, or

0:21:31.800 --> 0:21:36.000
<v Speaker 1>are the ones that are, for my corpsal reasons, unable

0:21:36.040 --> 0:21:39.720
<v Speaker 1>to be cultivated because they exist in these symbiotic relationships

0:21:40.040 --> 0:21:44.520
<v Speaker 1>with other plants, trees, and forest atmospheres, and so the

0:21:44.560 --> 0:21:47.640
<v Speaker 1>truffle is a common example, but of course shan trells

0:21:47.640 --> 0:21:51.080
<v Speaker 1>are like this as well. I believe also porcini mushrooms, uh,

0:21:51.119 --> 0:21:54.159
<v Speaker 1>that it's just really hard to recreate the conditions in

0:21:54.160 --> 0:21:58.880
<v Speaker 1>which they arise. Yeah. So even as as humanity inevitably

0:21:59.200 --> 0:22:02.520
<v Speaker 1>be you know that began this shift, uh, this revolution

0:22:02.600 --> 0:22:05.879
<v Speaker 1>in neolithic times, uh, shifting away from the hunter gathering

0:22:05.880 --> 0:22:10.439
<v Speaker 1>existence to one dependent on intensive agriculture, there's kind of this,

0:22:11.320 --> 0:22:12.800
<v Speaker 1>you know, this tendency to sort of think of that

0:22:12.840 --> 0:22:14.880
<v Speaker 1>as Okay, well, you know, you're just changing the way

0:22:14.960 --> 0:22:17.560
<v Speaker 1>you live entirely. You're just stopping where you are, and

0:22:17.600 --> 0:22:20.320
<v Speaker 1>now you're gonna grow plants and maybe mushroom foraging is

0:22:20.320 --> 0:22:22.960
<v Speaker 1>one of those things that remains outside of that tradition

0:22:23.200 --> 0:22:27.760
<v Speaker 1>for these very reasons we've been discussing UM. However, this

0:22:27.800 --> 0:22:29.679
<v Speaker 1>was quite interested. I was looking around for resources on

0:22:29.680 --> 0:22:31.879
<v Speaker 1>this and I ran across a paper published in the

0:22:31.920 --> 0:22:36.919
<v Speaker 1>Royal Society b by Curtis w. Uh Marine titled the

0:22:36.960 --> 0:22:40.439
<v Speaker 1>Transition to foraging for Dense and Predictable Resources and It's

0:22:40.480 --> 0:22:43.800
<v Speaker 1>Impact on the Evolution of modern humans. And in this

0:22:44.359 --> 0:22:48.479
<v Speaker 1>the uh the the author, UM, it's discussing you know

0:22:48.720 --> 0:22:50.959
<v Speaker 1>this basic shift, but he points out they point out

0:22:51.000 --> 0:22:53.840
<v Speaker 1>that there's another shift to consider. Quote the foraging shift

0:22:53.880 --> 0:22:56.960
<v Speaker 1>to dense and predictable resources is another key milestone that

0:22:57.040 --> 0:23:01.680
<v Speaker 1>had consequential impacts on the later part of human evolution. Now,

0:23:01.920 --> 0:23:04.760
<v Speaker 1>the basic idea here is that there wasn't just this

0:23:04.840 --> 0:23:08.119
<v Speaker 1>sudden shift from hunting and gathering to cultivation. And there

0:23:08.160 --> 0:23:12.040
<v Speaker 1>are many hypothesized explanations for this, but Marine argues that

0:23:12.119 --> 0:23:15.280
<v Speaker 1>hunting and gathering would have seen an increased focus on

0:23:15.359 --> 0:23:18.879
<v Speaker 1>dense and predictable resources. As such, this also means that

0:23:18.920 --> 0:23:22.960
<v Speaker 1>a given area becomes increasingly worth defending and staking a

0:23:23.080 --> 0:23:26.240
<v Speaker 1>claim to. Oh, this is interesting, So this could be

0:23:26.280 --> 0:23:30.640
<v Speaker 1>the transition point between UM between people who just roam

0:23:30.720 --> 0:23:34.359
<v Speaker 1>about following resources and consuming them wherever they can be found.

0:23:34.960 --> 0:23:38.600
<v Speaker 1>That and then on the other hand, having farmland in between,

0:23:38.680 --> 0:23:42.440
<v Speaker 1>you could have places where there are naturally high density

0:23:42.520 --> 0:23:45.439
<v Speaker 1>resources that can be exploited over and over that you

0:23:45.520 --> 0:23:48.720
<v Speaker 1>might not be quite farming yet but might be worth

0:23:48.840 --> 0:23:52.679
<v Speaker 1>defending as a stable territory. Yeah. Yeah, And I have

0:23:52.720 --> 0:23:54.720
<v Speaker 1>to admit I hadn't really thought about this before. I

0:23:54.840 --> 0:23:56.600
<v Speaker 1>without giving it a lot of thought. I always just

0:23:56.680 --> 0:23:59.560
<v Speaker 1>kind of, you know, had this this inaccurate picture in

0:23:59.600 --> 0:24:01.639
<v Speaker 1>my mind, and that was again like, Okay, we're not

0:24:01.720 --> 0:24:04.640
<v Speaker 1>hunter gathers anymore, let's start growing this corn. Why don't

0:24:04.720 --> 0:24:06.960
<v Speaker 1>we you know, like I don't, I didn't really think

0:24:07.000 --> 0:24:10.360
<v Speaker 1>about some of the potential, you know, for for areas

0:24:10.359 --> 0:24:13.160
<v Speaker 1>in between. This would be very interesting to explore. Paired

0:24:13.240 --> 0:24:15.439
<v Speaker 1>with something that came up in our Invention episodes on

0:24:15.520 --> 0:24:18.440
<v Speaker 1>bread and Toast, where we talked about the studies indicating

0:24:18.480 --> 0:24:22.800
<v Speaker 1>that bread and may actually have been invented before grain

0:24:23.160 --> 0:24:26.800
<v Speaker 1>was was an agricultural product like people may have been

0:24:26.840 --> 0:24:29.879
<v Speaker 1>making and I think the archaeological evidence is that people

0:24:29.960 --> 0:24:34.840
<v Speaker 1>were making bread from wild grains and wild grasses before

0:24:34.840 --> 0:24:38.080
<v Speaker 1>they had farms and wheat. Yeah. Absolutely. It makes me

0:24:38.119 --> 0:24:40.080
<v Speaker 1>wonder if they were getting these grains from some kind

0:24:40.080 --> 0:24:42.200
<v Speaker 1>of like location where there were a lot of them

0:24:42.400 --> 0:24:46.320
<v Speaker 1>growing together and could be exploited over and over again. Yeah, exactly.

0:24:46.880 --> 0:24:49.080
<v Speaker 1>Now marine rights to just some all this up quote.

0:24:49.200 --> 0:24:52.880
<v Speaker 1>I hypothesized that the origin population for modern humans made

0:24:52.880 --> 0:24:55.960
<v Speaker 1>this shift to dense and predictable resources, and thus was

0:24:56.000 --> 0:25:00.320
<v Speaker 1>subject to high levels of territoriality and intergroup con fleet,

0:25:00.520 --> 0:25:04.200
<v Speaker 1>which provided the selection regime for high levels of cooperation

0:25:04.640 --> 0:25:08.879
<v Speaker 1>with unrelated individuals within one's group. The downstream effect was

0:25:08.920 --> 0:25:13.640
<v Speaker 1>that all modern humans inherited these hyper pro social productivities

0:25:13.880 --> 0:25:17.320
<v Speaker 1>that are unique to our species. Now, to bring this

0:25:17.400 --> 0:25:21.080
<v Speaker 1>back to mushroom foraging, it is interesting to process one's

0:25:21.119 --> 0:25:24.359
<v Speaker 1>thoughts about the predictable times and places one will find,

0:25:24.440 --> 0:25:28.560
<v Speaker 1>say Chantrelle's or into the woods, and the competitive feelings

0:25:28.600 --> 0:25:31.160
<v Speaker 1>that they may force we may be forced to confront

0:25:31.280 --> 0:25:34.960
<v Speaker 1>during this. In fact, I understand that more serious mushroom

0:25:35.000 --> 0:25:38.919
<v Speaker 1>foragers are, you know, their loath to reveal the secrets uh,

0:25:39.160 --> 0:25:42.320
<v Speaker 1>their secret places, their quote unquote honey spots, uh, the

0:25:42.320 --> 0:25:46.280
<v Speaker 1>places where they can dependently find the best patches of mushroom.

0:25:46.400 --> 0:25:48.960
<v Speaker 1>Do you remember the story in Michael Pollen's book where

0:25:49.000 --> 0:25:53.040
<v Speaker 1>he's going hunting for psilocybin mushrooms with Paul Statements, and

0:25:53.080 --> 0:25:55.399
<v Speaker 1>he's going to great pains to try to tell you

0:25:55.440 --> 0:25:59.320
<v Speaker 1>what he's doing without revealing the site of Paul statements

0:25:59.640 --> 0:26:03.920
<v Speaker 1>mushroom hash. Oh yeah, yeah, because Paul really doesn't want

0:26:03.920 --> 0:26:07.960
<v Speaker 1>people to know where he gets them. That's his honey spot. Now.

0:26:08.320 --> 0:26:11.520
<v Speaker 1>I think though, that you can certainly see that with plants, especially,

0:26:11.560 --> 0:26:15.800
<v Speaker 1>how this could be this intermediary zone between hunting and

0:26:15.840 --> 0:26:18.879
<v Speaker 1>gathering and cultivation where you realize, oh, well, the the

0:26:19.440 --> 0:26:21.359
<v Speaker 1>wheat that we can make into bread, it grows really

0:26:21.359 --> 0:26:24.199
<v Speaker 1>well here. Uh this is a place that we need

0:26:24.240 --> 0:26:27.600
<v Speaker 1>to keep secret or even protect from other other individuals.

0:26:27.600 --> 0:26:29.800
<v Speaker 1>This is our spot, This is our sacred spot that

0:26:29.840 --> 0:26:33.080
<v Speaker 1>we return to. It's a very interesting possibility. I wonder

0:26:33.160 --> 0:26:36.240
<v Speaker 1>what what would be the evidence that you could find

0:26:36.280 --> 0:26:37.879
<v Speaker 1>to back that up. I don't know. I have to

0:26:37.960 --> 0:26:40.159
<v Speaker 1>keep thinking about that. All right, we're going to take

0:26:40.160 --> 0:26:45.920
<v Speaker 1>a quick break, but we'll be right back. And we're

0:26:45.960 --> 0:26:49.439
<v Speaker 1>back now. Another interesting topic to to consider in all

0:26:49.480 --> 0:26:54.040
<v Speaker 1>of this is that that there is essentially a foraging gene.

0:26:54.880 --> 0:26:58.480
<v Speaker 1>Uh So the key gene of note in most studies,

0:26:58.560 --> 0:27:01.520
<v Speaker 1>especially with fruit flies and fruit flies, it's p r

0:27:01.640 --> 0:27:05.480
<v Speaker 1>KG one. Uh and uh. This is um. This is

0:27:05.520 --> 0:27:10.120
<v Speaker 1>something that we see presented in a wide variety of animals,

0:27:10.119 --> 0:27:12.880
<v Speaker 1>from fruit flies to even humans. But p r KG

0:27:13.000 --> 0:27:16.240
<v Speaker 1>one is president fruit flies and has previously been shown

0:27:16.240 --> 0:27:20.800
<v Speaker 1>to influence foraging behaviors. Researchers and studies that I think

0:27:20.880 --> 0:27:23.879
<v Speaker 1>date back to at least have looked at this and

0:27:23.960 --> 0:27:27.159
<v Speaker 1>multiple researchers found that one variant of the gene and

0:27:27.200 --> 0:27:31.359
<v Speaker 1>fruit flies induces what is called sitter behavior and in

0:27:31.440 --> 0:27:35.040
<v Speaker 1>the other's rover behavior. Now, the difference here is that

0:27:35.080 --> 0:27:39.400
<v Speaker 1>when a sitter enters an area containing fruit, the they

0:27:39.440 --> 0:27:42.800
<v Speaker 1>scalut the perimeter of the area and then they move inward.

0:27:43.000 --> 0:27:44.600
<v Speaker 1>They sort of you know, they scouted out, They make

0:27:44.640 --> 0:27:47.960
<v Speaker 1>a perimeter, and then they move in. Rovers instead move

0:27:48.200 --> 0:27:52.560
<v Speaker 1>right in and go for the first fruit they encounter. Interesting. Now,

0:27:52.600 --> 0:27:56.360
<v Speaker 1>the human form of the gene is apparently a nucleotide

0:27:56.520 --> 0:28:02.080
<v Speaker 1>polymorphism genotype called r S one three four, and in

0:28:02.160 --> 0:28:06.000
<v Speaker 1>two thousand and nineteen, researchers from Canada, the US, and

0:28:06.040 --> 0:28:08.920
<v Speaker 1>the UK this would be struck at all um. They

0:28:08.920 --> 0:28:11.560
<v Speaker 1>experimented with it in a paper published in the Proceedings

0:28:11.640 --> 0:28:14.320
<v Speaker 1>of the National Academy of Science. UH. The title is

0:28:14.359 --> 0:28:17.680
<v Speaker 1>self regulation and the foraging gene p r KG one

0:28:17.720 --> 0:28:21.240
<v Speaker 1>in Humans. UH. Here's how the study went down. So,

0:28:21.320 --> 0:28:26.320
<v Speaker 1>the authors analyzed the genotypes of RS and four thirty

0:28:26.320 --> 0:28:31.760
<v Speaker 1>seven undergraduate students who performed two virtual foraging tasks. So

0:28:31.840 --> 0:28:35.040
<v Speaker 1>this was a touch screen situation in which subjects search

0:28:35.160 --> 0:28:38.400
<v Speaker 1>for and collected as many red berries as possible within

0:28:38.520 --> 0:28:42.120
<v Speaker 1>five minutes. And then so they compared the subjects with

0:28:42.280 --> 0:28:47.200
<v Speaker 1>C A or CC genotypes of rs UH. Individuals with

0:28:47.240 --> 0:28:50.280
<v Speaker 1>the A A genotype were more likely to hug the

0:28:50.320 --> 0:28:54.520
<v Speaker 1>boundary of the search environment, pick smaller berries, and stop

0:28:54.600 --> 0:28:57.880
<v Speaker 1>to pick berries and patches with fewer visible berries a

0:28:58.040 --> 0:29:01.720
<v Speaker 1>k A sitter behavior. The findings suggests that the A

0:29:01.720 --> 0:29:05.560
<v Speaker 1>A genotype is associated with a search strategy that restricts

0:29:05.600 --> 0:29:10.040
<v Speaker 1>exploration and exploits the local environment extensively. In other words,

0:29:10.280 --> 0:29:14.520
<v Speaker 1>distinct patterns of goal pursuit for foraging are associated with

0:29:14.560 --> 0:29:19.120
<v Speaker 1>particular genotypes of pr KG one. That's very interesting. Now,

0:29:19.160 --> 0:29:21.200
<v Speaker 1>as we've talked about on the show before, you always

0:29:21.240 --> 0:29:25.480
<v Speaker 1>have to remember when you're drawing correlations between particular gene

0:29:25.520 --> 0:29:28.480
<v Speaker 1>variants and a behavior. It's it's almost never going to

0:29:28.600 --> 0:29:30.760
<v Speaker 1>be like an on off switch that like, if you

0:29:30.800 --> 0:29:33.520
<v Speaker 1>have a certain gene variant, you show X behavior and

0:29:33.560 --> 0:29:35.920
<v Speaker 1>if you don't have it, you don't. But instead you

0:29:35.920 --> 0:29:39.480
<v Speaker 1>you'd be charting sort of like you know, percentages of influence.

0:29:39.520 --> 0:29:42.640
<v Speaker 1>Can can you see correlations between gene variants and a

0:29:42.800 --> 0:29:46.000
<v Speaker 1>and a tendency or a certain proclivity to a certain

0:29:46.000 --> 0:29:49.000
<v Speaker 1>type of behavior and uh and so yeah, this would

0:29:49.000 --> 0:29:53.600
<v Speaker 1>say that somehow foraging behaviors are downstream from things that

0:29:53.720 --> 0:29:56.520
<v Speaker 1>this gene does to the brain that makes you more

0:29:56.640 --> 0:29:59.240
<v Speaker 1>likely to kind of like go out on a long

0:29:59.320 --> 0:30:02.880
<v Speaker 1>search of versus try to exploit all of the resources

0:30:02.920 --> 0:30:06.880
<v Speaker 1>you can in your nearest immediate environment. Yeah, yeah, absolutely, Now,

0:30:06.920 --> 0:30:08.360
<v Speaker 1>and of course we also have to keep in mind

0:30:08.440 --> 0:30:11.160
<v Speaker 1>that the scope in the size of the study here.

0:30:11.240 --> 0:30:14.040
<v Speaker 1>But um, and also I should point that the authors

0:30:14.320 --> 0:30:18.080
<v Speaker 1>mentioned that the human foraging behavior is ultimately far more

0:30:18.120 --> 0:30:21.800
<v Speaker 1>complex than the the the foraging behavior fruit flies. And

0:30:21.840 --> 0:30:25.640
<v Speaker 1>instead of they're just being two distinct foraging strategies, it

0:30:25.680 --> 0:30:27.920
<v Speaker 1>seems like they are three. So you have sidderin rover,

0:30:28.040 --> 0:30:31.440
<v Speaker 1>but then you have a mixed uh disposition as well

0:30:31.480 --> 0:30:34.239
<v Speaker 1>the combines elements of both. But on top of that

0:30:34.240 --> 0:30:36.640
<v Speaker 1>that they point out that this would go beyond mere

0:30:36.760 --> 0:30:39.600
<v Speaker 1>foraging and humans, that that it that it would instead

0:30:39.680 --> 0:30:43.880
<v Speaker 1>impact human behavior regulation across multiple domains. And I think

0:30:43.920 --> 0:30:46.600
<v Speaker 1>we can imagine how, yeah, that would involve various things

0:30:46.600 --> 0:30:50.400
<v Speaker 1>that are like foraging, but also potentially impact just sort

0:30:50.440 --> 0:30:54.320
<v Speaker 1>of risk assessment, etcetera. Oh yeah, I mean, I think

0:30:54.320 --> 0:30:57.720
<v Speaker 1>it's easy to see how complex modern behaviors are in

0:30:57.760 --> 0:31:03.800
<v Speaker 1>a way kind of probably minor reconfigurations of traditional instinctual

0:31:03.840 --> 0:31:07.520
<v Speaker 1>behaviors like foraging, like hunting and that kind of thing. Uh,

0:31:07.560 --> 0:31:10.920
<v Speaker 1>So you can see how whatever we're most instinctually inclined

0:31:10.960 --> 0:31:13.720
<v Speaker 1>to do in terms of foraging could manifest in the

0:31:13.720 --> 0:31:16.959
<v Speaker 1>way you accomplish work around the house, in the way

0:31:17.000 --> 0:31:19.920
<v Speaker 1>that you, you know, go shopping or whatever. I mean again,

0:31:20.480 --> 0:31:22.760
<v Speaker 1>you you have to be careful about drawing too direct

0:31:23.080 --> 0:31:25.200
<v Speaker 1>an inference about anything like that, but the fact that

0:31:25.240 --> 0:31:30.040
<v Speaker 1>there's some kind of influences seems pretty clear. Alright, we're

0:31:30.040 --> 0:31:32.000
<v Speaker 1>going to take a quick break, but we'll be right back.

0:31:33.880 --> 0:31:39.000
<v Speaker 1>Thank And we're back now. Another aspect of early human

0:31:39.040 --> 0:31:42.200
<v Speaker 1>foraging tactics, and indeed, the way these these early humans

0:31:42.280 --> 0:31:45.640
<v Speaker 1>use spatial abilities to gather resources. Is that there was

0:31:45.680 --> 0:31:49.280
<v Speaker 1>seemingly a division of labor between males and females. This

0:31:49.360 --> 0:31:53.240
<v Speaker 1>is the sexual division of labor, sometimes abbreviated as sdl

0:31:53.840 --> 0:31:55.680
<v Speaker 1>UM and and this is a subject that has received

0:31:55.680 --> 0:31:59.200
<v Speaker 1>a lot of study over the years, especially of studies

0:31:59.240 --> 0:32:02.719
<v Speaker 1>that look at extent hunter gatherer populations in the world.

0:32:02.960 --> 0:32:06.680
<v Speaker 1>And there are varying hypotheses for the evolutionary origins of

0:32:06.720 --> 0:32:10.280
<v Speaker 1>this divide. Now for our purposes here, I was looking

0:32:10.360 --> 0:32:19.200
<v Speaker 1>at a study by Lewis Pacheco, Cobas, Marcos Rosetti, Cecilia Quanti, Equoyees,

0:32:19.800 --> 0:32:24.400
<v Speaker 1>and Robin Hudson titled sex differences in mushroom gathering Men

0:32:24.520 --> 0:32:28.120
<v Speaker 1>expend more energy to obtain equivalent benefits and this was

0:32:28.160 --> 0:32:31.920
<v Speaker 1>published in Evolution and Human Behavior back in So the

0:32:31.960 --> 0:32:35.400
<v Speaker 1>authors here pointed out that the evidence was accumulating quote

0:32:35.480 --> 0:32:39.320
<v Speaker 1>that women excel on tasks appropriate to gathering immobile plant

0:32:39.320 --> 0:32:42.640
<v Speaker 1>resources while men excel on tasks appropriate to hunting mobile,

0:32:42.720 --> 0:32:46.160
<v Speaker 1>unpredictable prey. And this would be due so the thinking

0:32:46.240 --> 0:32:50.280
<v Speaker 1>goes to this ancient labor divide in human societies. But

0:32:50.360 --> 0:32:54.320
<v Speaker 1>it also means that intrinsic foraging abilities and tactics would

0:32:54.320 --> 0:32:57.240
<v Speaker 1>differ from males to females. So the researchers here decided

0:32:57.400 --> 0:33:01.200
<v Speaker 1>to put this to the test with a mushroom foraging experiment,

0:33:01.720 --> 0:33:03.520
<v Speaker 1>which is the other key reason to discuss it here,

0:33:03.560 --> 0:33:06.320
<v Speaker 1>because people are are This is an experiment that includes

0:33:06.400 --> 0:33:10.080
<v Speaker 1>not touch screen um practices, not some sort of touch

0:33:10.120 --> 0:33:14.760
<v Speaker 1>screen experiment, but an actual foraging for mushrooms. Let's forage.

0:33:15.080 --> 0:33:18.080
<v Speaker 1>So in their study they use GPS and heart rate

0:33:18.120 --> 0:33:22.520
<v Speaker 1>monitors that had been affixed to the researchers themselves, and

0:33:22.520 --> 0:33:25.640
<v Speaker 1>then these researchers would follow twenty one pairs of men

0:33:25.680 --> 0:33:29.880
<v Speaker 1>and women from an indigenous Mexican community in uh tux

0:33:29.960 --> 0:33:33.320
<v Speaker 1>Cola while foraging for mushrooms in the wild. So the

0:33:33.360 --> 0:33:36.040
<v Speaker 1>researchers are the ones where in the gear they're following

0:33:36.080 --> 0:33:38.600
<v Speaker 1>the actual foragers, but in doing so, they're going to

0:33:38.680 --> 0:33:41.600
<v Speaker 1>be able to chart where the foragers went and how

0:33:41.680 --> 0:33:45.560
<v Speaker 1>much energy seems to be expended in the silent hunt.

0:33:46.520 --> 0:33:49.479
<v Speaker 1>So they ultimately measured the costs, the benefits, and the

0:33:49.520 --> 0:33:54.280
<v Speaker 1>general search efficiency of everyone's movements, and then they analyze them.

0:33:54.320 --> 0:33:57.840
<v Speaker 1>The resulting foraging patterns showed that while males and females

0:33:57.880 --> 0:34:02.080
<v Speaker 1>collected similar quantities of mushroom rooms. Males achieved this at

0:34:02.120 --> 0:34:05.400
<v Speaker 1>a significantly higher cost, so the males they traveled farther.

0:34:05.680 --> 0:34:09.759
<v Speaker 1>The males climbed to greater altitudes. They had higher mean

0:34:09.920 --> 0:34:14.840
<v Speaker 1>heart rates and energy expenditures while partaking in the foraging,

0:34:15.120 --> 0:34:18.640
<v Speaker 1>and in addition, they also collected fewer mushroom species and

0:34:18.760 --> 0:34:22.280
<v Speaker 1>visited fewer collection sites. And this is interesting. They seemed

0:34:22.320 --> 0:34:26.239
<v Speaker 1>to focus on large patches of mushrooms, even if these

0:34:26.280 --> 0:34:28.879
<v Speaker 1>were harder to come by, so they were like bypassing

0:34:29.000 --> 0:34:31.640
<v Speaker 1>or not even looking for those smaller patches they wanted

0:34:31.680 --> 0:34:36.440
<v Speaker 1>wanted to get the big game mushroom patches. The females, meanwhile,

0:34:36.719 --> 0:34:39.400
<v Speaker 1>it seemed to know where to go and they foraged

0:34:40.160 --> 0:34:42.839
<v Speaker 1>from many small patches as opposed to seeking out those

0:34:42.880 --> 0:34:46.160
<v Speaker 1>greater patches of fun guy. This was also compared by

0:34:46.160 --> 0:34:48.480
<v Speaker 1>the way to previous research on the way males and

0:34:48.560 --> 0:34:52.680
<v Speaker 1>females navigate, which indicated that males tend to create mental

0:34:52.760 --> 0:34:56.960
<v Speaker 1>maps and then superimpose their position while womington to remember

0:34:57.080 --> 0:35:02.040
<v Speaker 1>landmarks and memorize the routes quote. These findings are consistent

0:35:02.080 --> 0:35:04.920
<v Speaker 1>with arguments in the literature that differences in spatial ability

0:35:05.000 --> 0:35:08.359
<v Speaker 1>between the sexes are domain dependent, with women performing better

0:35:08.400 --> 0:35:11.360
<v Speaker 1>and more readily adopting search strategies appropriate to a gathering

0:35:11.400 --> 0:35:15.399
<v Speaker 1>lifestyle than men. So basically the idea is that if

0:35:15.400 --> 0:35:18.439
<v Speaker 1>you were primarily charged with hunting prey two point five

0:35:18.440 --> 0:35:22.000
<v Speaker 1>million years ago, it made sense to travel far, to

0:35:22.080 --> 0:35:26.319
<v Speaker 1>take widening paths in pursuit of that big payoff prey,

0:35:26.360 --> 0:35:29.720
<v Speaker 1>and then take the shortest, most direct path back home

0:35:30.040 --> 0:35:32.000
<v Speaker 1>so as to make up for all that time you

0:35:32.040 --> 0:35:36.399
<v Speaker 1>spent wandering and pursuing the prey. Meanwhile, if you were

0:35:36.440 --> 0:35:40.279
<v Speaker 1>tasked with gathering fungi or plants, it would serve to

0:35:40.400 --> 0:35:43.880
<v Speaker 1>remember where the most productive plant food sources were found,

0:35:43.960 --> 0:35:46.960
<v Speaker 1>you know, those honey spots, and then retrace your steps

0:35:47.040 --> 0:35:50.160
<v Speaker 1>exactly so as to take advantage of them in the future.

0:35:50.160 --> 0:35:52.720
<v Speaker 1>And like, no, making a bee line back for camp.

0:35:53.360 --> 0:35:56.200
<v Speaker 1>That's very interesting. Uh Now. One thing that we always

0:35:56.239 --> 0:35:58.840
<v Speaker 1>got to say whenever you talk about studies that explore

0:35:58.880 --> 0:36:01.680
<v Speaker 1>sex differences is that people a lot of people like

0:36:01.760 --> 0:36:04.720
<v Speaker 1>to take these and really run with them and say like, oh,

0:36:04.760 --> 0:36:07.520
<v Speaker 1>this means that men are like this and women are

0:36:07.600 --> 0:36:10.520
<v Speaker 1>like that. I think we always try to caution people

0:36:10.600 --> 0:36:14.400
<v Speaker 1>not to not to over interpret findings of sex differences

0:36:14.480 --> 0:36:18.360
<v Speaker 1>in in particular studies. It's very easy, I think, just

0:36:18.400 --> 0:36:22.160
<v Speaker 1>because people want to have strong intuitions about gender and

0:36:22.239 --> 0:36:24.640
<v Speaker 1>sex and like what men are like and what women

0:36:24.680 --> 0:36:27.280
<v Speaker 1>are like and stuff that they want to say like, oh,

0:36:27.360 --> 0:36:30.560
<v Speaker 1>this explains why my husband does this or why my

0:36:30.640 --> 0:36:33.319
<v Speaker 1>girlfriend says that kind of thing. You can you can

0:36:33.360 --> 0:36:36.960
<v Speaker 1>easily go way overboard with with looking for explanations in

0:36:36.960 --> 0:36:39.319
<v Speaker 1>that way. Yeah, I mean it also it comes down

0:36:39.320 --> 0:36:41.600
<v Speaker 1>to what is the Barnum effect that we've discussed before,

0:36:42.120 --> 0:36:44.800
<v Speaker 1>where we say, oh, well, that's me, this this study

0:36:44.840 --> 0:36:47.759
<v Speaker 1>is correct because that's me. I totally am like that

0:36:47.800 --> 0:36:49.799
<v Speaker 1>when I go to the to the grocery store and

0:36:49.840 --> 0:36:53.319
<v Speaker 1>my my partner is like this, etcetera. But but yeah,

0:36:53.400 --> 0:36:57.440
<v Speaker 1>like you're saying, like, we're talking about general perceived trends

0:36:57.520 --> 0:37:00.919
<v Speaker 1>in the sexual division of labor and as reflected here

0:37:00.960 --> 0:37:05.160
<v Speaker 1>in particular studies. Uh so, yeah. I don't don't have

0:37:05.200 --> 0:37:07.319
<v Speaker 1>it printed on a T shirt or anything, but but

0:37:07.719 --> 0:37:10.439
<v Speaker 1>it is interesting research and and certainly it was neat

0:37:10.520 --> 0:37:13.760
<v Speaker 1>to find a study that was that was actually involving

0:37:14.000 --> 0:37:19.520
<v Speaker 1>mushroom foraging, like the scientific study of mushroom foraging behavior totally,

0:37:19.560 --> 0:37:21.400
<v Speaker 1>and it highlights how there can be different types of

0:37:21.440 --> 0:37:24.200
<v Speaker 1>foraging strategies that are effective in different ways. I was

0:37:24.239 --> 0:37:27.120
<v Speaker 1>looking at some other studies that were about different types

0:37:27.160 --> 0:37:30.120
<v Speaker 1>of foraging strategies and birds, you know, and how this

0:37:30.160 --> 0:37:33.000
<v Speaker 1>is kind of interesting, like some birds tend to forage

0:37:33.000 --> 0:37:36.319
<v Speaker 1>by moving in little random types of motions around a

0:37:36.360 --> 0:37:39.640
<v Speaker 1>central locust, uh in a way that's very comparable actually

0:37:39.680 --> 0:37:43.360
<v Speaker 1>to the movement of tiny particles on the atomic scale

0:37:43.400 --> 0:37:46.919
<v Speaker 1>that's known as Brownie in motion and physics. Whereas other

0:37:46.960 --> 0:37:50.800
<v Speaker 1>birds tended to forage by sort of taking large leaps

0:37:50.880 --> 0:37:54.480
<v Speaker 1>at a time, and that these uh, these different strategies

0:37:54.480 --> 0:37:57.720
<v Speaker 1>could be differentially effective depending on what types of things

0:37:57.760 --> 0:38:01.560
<v Speaker 1>you're looking for while foraging, what the surrounding landscape is,

0:38:01.600 --> 0:38:04.440
<v Speaker 1>and things like that. Yeah, it's such a foraging itself

0:38:04.520 --> 0:38:07.000
<v Speaker 1>is just such a fascinating thing to think about, because

0:38:07.520 --> 0:38:09.160
<v Speaker 1>it's easy to just sort of dismiss it as this

0:38:09.239 --> 0:38:12.200
<v Speaker 1>kind of primal thing that we sometimes engage in when

0:38:12.280 --> 0:38:14.800
<v Speaker 1>we decided to go into the woods and look for mushrooms, etcetera.

0:38:15.160 --> 0:38:18.920
<v Speaker 1>But it is again something basic like neural activity that

0:38:18.960 --> 0:38:22.399
<v Speaker 1>we're continually engaging in and and something that also comes

0:38:22.400 --> 0:38:24.640
<v Speaker 1>down to this kind of like like this the basic

0:38:24.719 --> 0:38:27.720
<v Speaker 1>mathematics of it, like how do you go about looking

0:38:27.760 --> 0:38:30.319
<v Speaker 1>for resources in a given area? And then how are

0:38:30.320 --> 0:38:32.560
<v Speaker 1>you how do you deal with spatial awareness in that

0:38:32.640 --> 0:38:35.520
<v Speaker 1>given area? Like there it seems like a rich domain

0:38:35.760 --> 0:38:39.200
<v Speaker 1>for you know, AI research and the like totally because

0:38:39.520 --> 0:38:43.640
<v Speaker 1>strangely enough, I feel like search activities are one of

0:38:43.680 --> 0:38:48.480
<v Speaker 1>the ways in which human behavior can be most closely

0:38:49.120 --> 0:38:53.360
<v Speaker 1>compared to what computer programs do. Does that make sense? Yeah? No, no,

0:38:53.440 --> 0:38:57.240
<v Speaker 1>absolutely that there are some pretty direct analogies actually having

0:38:57.239 --> 0:39:01.520
<v Speaker 1>to do with energy is expended an efficiency in different

0:39:01.600 --> 0:39:06.880
<v Speaker 1>ways of searching through randomly organized material. Yeah, yeah, absolutely.

0:39:06.960 --> 0:39:08.520
<v Speaker 1>I mean in the same way that you could imagine

0:39:08.560 --> 0:39:12.840
<v Speaker 1>someone in desiring an AI program that will find you

0:39:12.840 --> 0:39:15.160
<v Speaker 1>a good deal on something. There are also plenty of

0:39:15.200 --> 0:39:17.200
<v Speaker 1>humans out there like that's their thing, like let me,

0:39:17.320 --> 0:39:18.880
<v Speaker 1>let me help you find a good deal on that,

0:39:18.920 --> 0:39:21.600
<v Speaker 1>because I love looking for them. So yeah, I mean

0:39:21.880 --> 0:39:24.440
<v Speaker 1>a lot of it does come back to foraging. I

0:39:24.440 --> 0:39:28.160
<v Speaker 1>mean I would be interested in studies looking at foraging

0:39:28.239 --> 0:39:32.560
<v Speaker 1>behaviors in humans and animals compared to what search engines

0:39:32.640 --> 0:39:35.440
<v Speaker 1>do to get you your results. That would be interesting.

0:39:35.480 --> 0:39:39.640
<v Speaker 1>So who knows, perhaps we'll have some additional foraging episodes

0:39:39.760 --> 0:39:41.960
<v Speaker 1>in the future as as you and I go out

0:39:42.000 --> 0:39:49.040
<v Speaker 1>into the wilds seeking out fruitful papers on these topics.

0:39:49.320 --> 0:39:51.680
<v Speaker 1>Bring it on home, all right, We're gonna have to

0:39:51.760 --> 0:39:54.600
<v Speaker 1>call it there. Likewise, we weren't able to touch on

0:39:54.680 --> 0:39:58.920
<v Speaker 1>everything regarding mushroom foraging and foraging related topics here, but

0:39:58.920 --> 0:40:01.359
<v Speaker 1>we certainly would love to hear for rememberyone out there, Um,

0:40:01.520 --> 0:40:04.160
<v Speaker 1>you know, are you involved in in mushroom foraging? Are

0:40:04.200 --> 0:40:08.000
<v Speaker 1>you an active forager or let us know your experiences.

0:40:08.040 --> 0:40:11.000
<v Speaker 1>We'd love to hear your insight on all of this. Likewise,

0:40:11.040 --> 0:40:14.000
<v Speaker 1>if you were if your culture of origin, or you're

0:40:14.040 --> 0:40:16.839
<v Speaker 1>you know, if you're immersed in a particular cultural uh

0:40:17.000 --> 0:40:20.440
<v Speaker 1>take on mushroom foraging, be it you know, the activities

0:40:20.600 --> 0:40:24.280
<v Speaker 1>or or beliefs and strategies tied up with the foraging

0:40:24.440 --> 0:40:28.120
<v Speaker 1>uh activity, let us know. We'd love to be enlightened

0:40:28.120 --> 0:40:31.280
<v Speaker 1>on those topics. Huge things. As always to our excellent
