0:00:05.880 --> 0:00:07.800
<v Speaker 1>Hey, you welcome to Stuff to Blow Your Mind. My

0:00:07.880 --> 0:00:11.080
<v Speaker 1>name is Robert Lamb. Joe is out sick today, and

0:00:11.240 --> 0:00:13.800
<v Speaker 1>normally we would have a new core episode of Stuff

0:00:13.800 --> 0:00:16.520
<v Speaker 1>to Blow Your Mind for you, but we're going to

0:00:16.560 --> 0:00:19.639
<v Speaker 1>go ahead and bust out the next Vault episode a

0:00:19.680 --> 0:00:21.600
<v Speaker 1>little early to just to give us a little more

0:00:21.640 --> 0:00:23.400
<v Speaker 1>breathing room here. So this is going to be the

0:00:23.440 --> 0:00:26.920
<v Speaker 1>Beast War and Apron Part two. Originally published on March

0:00:27.000 --> 0:00:34.200
<v Speaker 1>twenty fourth, twenty twenty two. We hope you enjoy Welcome

0:00:34.240 --> 0:00:43.920
<v Speaker 1>to Stuff to Blow Your Mind production of iHeartRadio. Hey,

0:00:44.040 --> 0:00:46.040
<v Speaker 1>welcome to Stuff to Blow Your Mind. My name is

0:00:46.120 --> 0:00:48.680
<v Speaker 1>Robert Lamb, and I'm Joe McCormick, and we're back with

0:00:48.760 --> 0:00:52.200
<v Speaker 1>part two of our series on animals cooking non human

0:00:52.240 --> 0:00:55.240
<v Speaker 1>animals and cooking in the sense of doing things to

0:00:55.320 --> 0:00:58.280
<v Speaker 1>food before they eat it other than applying heat. Because

0:00:58.320 --> 0:01:01.480
<v Speaker 1>in the last episode we talked about how humans are

0:01:01.520 --> 0:01:04.839
<v Speaker 1>the only animals that regularly apply heat to their food

0:01:04.840 --> 0:01:07.280
<v Speaker 1>on purpose to cook it, but animals do all kinds

0:01:07.319 --> 0:01:09.920
<v Speaker 1>of other interesting things to their food before eating it.

0:01:09.959 --> 0:01:13.640
<v Speaker 1>For example, we talked about birds that that sort of

0:01:13.760 --> 0:01:17.800
<v Speaker 1>butcher and smash up and process their their their animal

0:01:17.880 --> 0:01:20.440
<v Speaker 1>parts before they consume them in various ways, like the

0:01:20.800 --> 0:01:24.759
<v Speaker 1>shrike making shish kebabs out of crickets and other critters.

0:01:24.760 --> 0:01:27.679
<v Speaker 1>And uh, was it the lambur guyer that would would

0:01:27.680 --> 0:01:31.640
<v Speaker 1>smash the bones or the turtles? Yeah? And you know,

0:01:31.720 --> 0:01:34.720
<v Speaker 1>I realized after a record of that episode that there's

0:01:34.760 --> 0:01:39.400
<v Speaker 1>another animal that cooks that is a part of my

0:01:39.440 --> 0:01:42.600
<v Speaker 1>weekly life that I forgot to mention. It's that little

0:01:42.640 --> 0:01:47.160
<v Speaker 1>puff on Instagram account in which a cat is made

0:01:47.200 --> 0:01:51.240
<v Speaker 1>to appear to cook various items to try to replicate

0:01:51.520 --> 0:01:56.040
<v Speaker 1>various sort of like TikTok cooking trends and crafting trends

0:01:56.600 --> 0:02:02.480
<v Speaker 1>um sometimes to great success, sometimes it results in disappointing failure.

0:02:02.720 --> 0:02:06.120
<v Speaker 1>Oh if if you're familiar with TikTok cooking trends, there's

0:02:06.160 --> 0:02:09.320
<v Speaker 1>one that I've seen by image alone. Do you can

0:02:09.360 --> 0:02:11.400
<v Speaker 1>you explain the thing to me where somebody takes a

0:02:11.400 --> 0:02:14.160
<v Speaker 1>big old wad of hamburger meat and they wrap it

0:02:14.240 --> 0:02:17.160
<v Speaker 1>around dry pasta. What is that? Do you know what

0:02:17.200 --> 0:02:20.800
<v Speaker 1>I'm talking about? Well, I am only familiar with TikTok

0:02:22.240 --> 0:02:26.320
<v Speaker 1>cooking trends that have been featured on that little puff,

0:02:26.440 --> 0:02:29.320
<v Speaker 1>so I don't think I've seen the cat doing this

0:02:29.480 --> 0:02:33.480
<v Speaker 1>to hamburger made yet So I'm not the one to

0:02:33.520 --> 0:02:35.520
<v Speaker 1>answer that question. Well, I mean it sounds like a

0:02:35.560 --> 0:02:38.519
<v Speaker 1>cat's idea. Well, to be clear, this cat is not

0:02:38.639 --> 0:02:42.000
<v Speaker 1>actually has not been trained to do anything. It's it's

0:02:42.040 --> 0:02:44.960
<v Speaker 1>just the appearance of a cat cooking that they have

0:02:45.520 --> 0:02:49.840
<v Speaker 1>created here trick photography. Yeah, cats lousy cooks. They're not,

0:02:49.840 --> 0:02:52.239
<v Speaker 1>they're not interested in cooking. But to tie it into

0:02:52.240 --> 0:02:54.680
<v Speaker 1>our first segment here, you know, one thing that is

0:02:54.720 --> 0:02:57.480
<v Speaker 1>great about cats is cats are very clean. You know,

0:02:57.520 --> 0:03:00.280
<v Speaker 1>they enjoy it. They groom themselves, they clean themselves. They

0:03:00.320 --> 0:03:03.000
<v Speaker 1>lick all over to get the dirt out of the fur. Actually,

0:03:03.040 --> 0:03:05.200
<v Speaker 1>I don't know if that's why they lick. They lick themselves.

0:03:05.240 --> 0:03:07.480
<v Speaker 1>It appears to be for some kind of hygienic purpose.

0:03:08.400 --> 0:03:10.560
<v Speaker 1>I have no idea what it's actually for, but that

0:03:10.720 --> 0:03:13.639
<v Speaker 1>mirrors some of the behaviors were about to talk about

0:03:13.680 --> 0:03:17.280
<v Speaker 1>in the category of animals washing their food before they

0:03:17.320 --> 0:03:20.560
<v Speaker 1>eat it. And Robert, I don't know about your house,

0:03:20.600 --> 0:03:25.359
<v Speaker 1>but I tend to be pretty fastidious about washing fresh produce.

0:03:25.520 --> 0:03:27.320
<v Speaker 1>Do you do the same, Well, you know, I don't

0:03:27.360 --> 0:03:31.160
<v Speaker 1>want any grit in whatever I'm cooking, And certainly, depending

0:03:31.200 --> 0:03:33.280
<v Speaker 1>on the produce in question, you might get some grit

0:03:33.320 --> 0:03:35.440
<v Speaker 1>if you don't wash it off. Well, if I'm make

0:03:35.480 --> 0:03:36.960
<v Speaker 1>an ants on a log, I want to make sure

0:03:37.000 --> 0:03:40.480
<v Speaker 1>that I have a scrub my celery sticks off before

0:03:40.760 --> 0:03:43.480
<v Speaker 1>and then dry them, you know, before I actually start

0:03:43.520 --> 0:03:47.520
<v Speaker 1>applying the peanut butter, and said ants. Well, it turns

0:03:47.520 --> 0:03:51.720
<v Speaker 1>out this is one of the food preprocessing behaviors that

0:03:51.920 --> 0:03:55.440
<v Speaker 1>is not unique to humans. All kinds of animals exhibit

0:03:55.800 --> 0:03:59.600
<v Speaker 1>various washing behaviors. And I'm want to say washing with

0:03:59.680 --> 0:04:02.840
<v Speaker 1>scare quotes because in some cases this may actually be

0:04:02.880 --> 0:04:06.400
<v Speaker 1>related to cleaning dirt or other materials off of the food,

0:04:06.600 --> 0:04:09.600
<v Speaker 1>and in other cases it may have a completely different purpose.

0:04:09.640 --> 0:04:11.520
<v Speaker 1>But in any case, it is taking a piece of

0:04:11.560 --> 0:04:14.720
<v Speaker 1>food and washing it, or doing something that looks like

0:04:14.800 --> 0:04:18.880
<v Speaker 1>washing with the help of water, that's right. I was

0:04:18.920 --> 0:04:23.080
<v Speaker 1>reading about some of this in a paper titled food

0:04:23.120 --> 0:04:28.200
<v Speaker 1>dunking Behavior by an Eurasian Jay by Dearborn and Gager,

0:04:28.600 --> 0:04:31.920
<v Speaker 1>published in the Ornithological Society of the Middle East. They

0:04:31.920 --> 0:04:34.359
<v Speaker 1>point out that crows and ravens have been observed to

0:04:34.680 --> 0:04:37.680
<v Speaker 1>quote unquote wash their food and fountains before eating it,

0:04:39.040 --> 0:04:41.280
<v Speaker 1>and they talk a little bit about how generally we

0:04:41.320 --> 0:04:46.480
<v Speaker 1>see examples of this washing behavior in primates and birds

0:04:47.360 --> 0:04:52.560
<v Speaker 1>washing or dunking, and in both birds and primates, the

0:04:52.600 --> 0:04:56.440
<v Speaker 1>two main theories seem to be that it's about washing

0:04:56.520 --> 0:04:58.960
<v Speaker 1>or removing a thin coating from the exterior the food,

0:04:59.000 --> 0:05:02.799
<v Speaker 1>which generally that what we're doing, or it's about making

0:05:02.800 --> 0:05:07.400
<v Speaker 1>the food easier to eat, which is not something we're

0:05:07.520 --> 0:05:10.599
<v Speaker 1>usually doing if we're just washing our produce in the sink,

0:05:11.000 --> 0:05:14.159
<v Speaker 1>but it is what we're doing if we're say, dipping

0:05:14.200 --> 0:05:18.559
<v Speaker 1>a particularly tough biscuit into a cup of tea or something. Yeah,

0:05:18.560 --> 0:05:21.480
<v Speaker 1>this the old hardtack tradition, you know, armies of old

0:05:21.600 --> 0:05:24.520
<v Speaker 1>marching around or sailing around with hard tack biscuits a

0:05:24.520 --> 0:05:26.960
<v Speaker 1>lot of times. Like, you can't even eat these things straight.

0:05:27.000 --> 0:05:29.039
<v Speaker 1>You can't just bite into them. You got to like

0:05:29.240 --> 0:05:31.400
<v Speaker 1>dip them into your gravy or some other kind of

0:05:31.440 --> 0:05:34.920
<v Speaker 1>liquid and then soften them up before you can consume. Yeah.

0:05:35.040 --> 0:05:37.080
<v Speaker 1>So some of the examples that they mentioned in this

0:05:37.120 --> 0:05:41.920
<v Speaker 1>paper from other creatures are carrion crows eating dry bread.

0:05:42.040 --> 0:05:43.840
<v Speaker 1>This would be a situation where dry bread has been

0:05:43.839 --> 0:05:47.839
<v Speaker 1>provided for them and they dip it before they eat it.

0:05:48.560 --> 0:05:53.080
<v Speaker 1>Kill deer have been observed washing muddy frogs off before

0:05:53.080 --> 0:05:55.040
<v Speaker 1>they eat them. The cacs have been observed doing the

0:05:55.080 --> 0:05:59.880
<v Speaker 1>same thing with sandy crabs. Captive monkeys have been a

0:06:00.000 --> 0:06:02.880
<v Speaker 1>deserve doing this with dry monkey chow. And then the

0:06:02.920 --> 0:06:06.040
<v Speaker 1>Eurasian jay example studied in the paper I cited. It

0:06:06.080 --> 0:06:08.880
<v Speaker 1>involves the bird in question dunking an egg in water

0:06:09.000 --> 0:06:13.240
<v Speaker 1>and then eating it, though the researchers ultimately remained they

0:06:13.240 --> 0:06:16.359
<v Speaker 1>remained unclear about what that was all about. Yeah, and

0:06:16.400 --> 0:06:18.719
<v Speaker 1>in a lot of cases, it seems like these washing, dunking,

0:06:18.800 --> 0:06:22.600
<v Speaker 1>or dousing behaviors are still they're still unknown, and we

0:06:22.640 --> 0:06:24.560
<v Speaker 1>still don't know exactly what the cause is that we

0:06:24.600 --> 0:06:28.520
<v Speaker 1>have better ideas in some cases than in others. But

0:06:29.040 --> 0:06:31.560
<v Speaker 1>one thing I was thinking about is that, you know,

0:06:31.600 --> 0:06:34.120
<v Speaker 1>it may depend on your anatomy how important it is

0:06:34.160 --> 0:06:36.960
<v Speaker 1>to douse something in external water before you eat it,

0:06:37.000 --> 0:06:40.120
<v Speaker 1>depending on how strong your salivary glands are, because we're

0:06:40.120 --> 0:06:42.320
<v Speaker 1>doing the same thing, but it happens in our mouths,

0:06:42.320 --> 0:06:44.240
<v Speaker 1>I mean, all the foods you eat. It gets kind

0:06:44.240 --> 0:06:47.479
<v Speaker 1>of like coated in saliva and moistened that way, and

0:06:47.520 --> 0:06:52.520
<v Speaker 1>it helps lubricate the swallowing process. Doesn't that sound so appetizing. Yeah, well,

0:06:52.560 --> 0:06:54.799
<v Speaker 1>I think we've we've touched on this before, but actually

0:06:54.880 --> 0:06:57.960
<v Speaker 1>quite recently, I think talking about food and digestion. But

0:06:58.240 --> 0:07:01.600
<v Speaker 1>like the digestive process begins in the mouth, like this

0:07:01.680 --> 0:07:06.680
<v Speaker 1>is where food is initially masticated, broken up, broken down,

0:07:08.160 --> 0:07:11.240
<v Speaker 1>partially liquefied, and then formed into that bolus that will

0:07:11.240 --> 0:07:14.560
<v Speaker 1>then have been be swallowed and continue the journey. You

0:07:14.560 --> 0:07:17.160
<v Speaker 1>don't want to be swallowing a dry bolus. No, no,

0:07:17.840 --> 0:07:19.960
<v Speaker 1>But next, I wanted to think about one of the

0:07:20.000 --> 0:07:23.120
<v Speaker 1>most famous examples of animals that appear at least to

0:07:23.280 --> 0:07:26.640
<v Speaker 1>wash their food before eating it, and that is raccoons.

0:07:26.720 --> 0:07:28.760
<v Speaker 1>This has got to be one of the cutest examples.

0:07:28.840 --> 0:07:30.960
<v Speaker 1>I'm sure everybody out there on the Internet at this

0:07:31.040 --> 0:07:34.920
<v Speaker 1>point has seen the heartbreaking video of the raccoon with

0:07:35.000 --> 0:07:37.480
<v Speaker 1>a piece of cotton candy going to the water's edge

0:07:37.480 --> 0:07:40.120
<v Speaker 1>to wash it and then it dissolving, and the raccoon

0:07:40.160 --> 0:07:44.120
<v Speaker 1>looks just so sad. I don't think I've seen that one,

0:07:44.160 --> 0:07:46.400
<v Speaker 1>but I'm picturing it. I can imagine it. So I

0:07:46.440 --> 0:07:48.440
<v Speaker 1>found something out I didn't know before. You you know,

0:07:48.640 --> 0:07:52.800
<v Speaker 1>the word raccoon. The English word raccoon is derived from

0:07:52.840 --> 0:07:56.600
<v Speaker 1>a word originally in the Algonquian languages. But do you

0:07:56.600 --> 0:07:59.200
<v Speaker 1>know what the raccoon is called in German? No, what

0:07:59.320 --> 0:08:02.720
<v Speaker 1>is it called? It is the vah bear, the wash bear,

0:08:02.920 --> 0:08:06.720
<v Speaker 1>the bear, the washes oh nice. And the same principle

0:08:06.760 --> 0:08:10.040
<v Speaker 1>shows up in its scientific name, which is procyon lowtour,

0:08:10.600 --> 0:08:15.120
<v Speaker 1>which means something like pre dog washer. So a raccoon

0:08:15.160 --> 0:08:17.360
<v Speaker 1>is something that's maybe not quite a dog, not quite

0:08:17.400 --> 0:08:20.760
<v Speaker 1>a dog yet, but it is associated with washing. And

0:08:20.840 --> 0:08:24.280
<v Speaker 1>this etymology carries over multiple languages where the raccoon is

0:08:24.800 --> 0:08:27.720
<v Speaker 1>known as something like the washing bear or the washing

0:08:27.760 --> 0:08:31.160
<v Speaker 1>dog or something like that, and it reflects one of

0:08:31.200 --> 0:08:34.480
<v Speaker 1>the most notable characteristic behaviors of the raccoon, which is

0:08:34.480 --> 0:08:36.640
<v Speaker 1>the fact that when they acquire a piece of food

0:08:36.800 --> 0:08:40.080
<v Speaker 1>and there is water nearby, they will often dunk that

0:08:40.160 --> 0:08:43.200
<v Speaker 1>piece of food in the water and then manipulate it,

0:08:43.320 --> 0:08:45.240
<v Speaker 1>kind of put it in the water and swish it

0:08:45.280 --> 0:08:47.760
<v Speaker 1>around a bit, maybe feel at it, paw at it,

0:08:48.240 --> 0:08:50.920
<v Speaker 1>rub on it, and then retrieve it from the water

0:08:51.240 --> 0:08:53.880
<v Speaker 1>and eat it. And it gives rise to the idea

0:08:53.920 --> 0:08:57.320
<v Speaker 1>that raccoons are meticulous, little neat freaks that they're I

0:08:57.320 --> 0:09:00.720
<v Speaker 1>don't know, hyper hygienic or germophobes or something washing every

0:09:00.720 --> 0:09:03.600
<v Speaker 1>bit of dirt and grime from food before consuming it,

0:09:04.520 --> 0:09:06.720
<v Speaker 1>which is kind of funny when you think about other

0:09:06.920 --> 0:09:09.920
<v Speaker 1>feeding habits of raccoons you might be familiar with, such

0:09:09.960 --> 0:09:12.840
<v Speaker 1>as like getting into your garbage can and just eating

0:09:12.840 --> 0:09:14.720
<v Speaker 1>the food in there, and they're not washing that food.

0:09:14.760 --> 0:09:16.520
<v Speaker 1>They don't seem to be concerned about the dirt in

0:09:16.559 --> 0:09:19.120
<v Speaker 1>that case. No, no, this is of course what it

0:09:19.160 --> 0:09:23.480
<v Speaker 1>has earned them the nickname trash pandas before, because they yeah,

0:09:23.520 --> 0:09:26.720
<v Speaker 1>there's straight up in the garbage can, or certainly they will.

0:09:26.760 --> 0:09:30.640
<v Speaker 1>They don't need to be by a stream to eat.

0:09:30.200 --> 0:09:34.600
<v Speaker 1>You can find poluty of evidence of raccoons eating without

0:09:34.600 --> 0:09:38.400
<v Speaker 1>a handy washing station nearby. Right, So it's an activity

0:09:38.440 --> 0:09:41.440
<v Speaker 1>that they do often enough that it's in the name,

0:09:41.640 --> 0:09:44.319
<v Speaker 1>like they're clearly known for it, But they don't always

0:09:44.360 --> 0:09:48.079
<v Speaker 1>do it. It appears to be optional, occasional, but again

0:09:48.200 --> 0:09:51.480
<v Speaker 1>common enough that it has become a characteristic feature of

0:09:51.480 --> 0:09:54.760
<v Speaker 1>the species. And so there's a big question like what

0:09:54.800 --> 0:09:57.400
<v Speaker 1>are they doing. Are they actually trying to get dirt

0:09:57.520 --> 0:10:00.000
<v Speaker 1>off of the food, or are they doing something else?

0:10:00.480 --> 0:10:03.319
<v Speaker 1>And there have been experiments that looked into this. So

0:10:03.400 --> 0:10:07.040
<v Speaker 1>one study I wanted to look at was by Malcolm

0:10:07.200 --> 0:10:11.560
<v Speaker 1>Lyle Watson, published in Proceedings of the Zoological Society of

0:10:11.640 --> 0:10:15.800
<v Speaker 1>London in nineteen sixty three, called a Critical Reexamination of

0:10:15.880 --> 0:10:20.880
<v Speaker 1>food washing behavior in the Raccoon or procyon lowtour. Now,

0:10:20.920 --> 0:10:25.160
<v Speaker 1>one thing this article says that I found alleged elsewhere

0:10:25.160 --> 0:10:28.800
<v Speaker 1>on the internet is that raccoon food dowsing behavior, and

0:10:28.840 --> 0:10:32.800
<v Speaker 1>it calls the behavior dowsing instead of washing to avoid

0:10:32.880 --> 0:10:36.280
<v Speaker 1>prejudging the issue of the purpose of the dowsing. Raccoons

0:10:36.320 --> 0:10:39.040
<v Speaker 1>put their food in water very often, but we don't

0:10:39.040 --> 0:10:41.320
<v Speaker 1>know exactly why they're doing it yet, so they say

0:10:41.360 --> 0:10:45.240
<v Speaker 1>dowsing instead of washing. So dowsing behavior is something that

0:10:45.280 --> 0:10:49.280
<v Speaker 1>the author here says is only seen in raccoons in captivity.

0:10:49.840 --> 0:10:53.199
<v Speaker 1>But I kind of doubt that. I've just browsing around.

0:10:53.200 --> 0:10:55.640
<v Speaker 1>I've read plenty of reports of people saying they observed

0:10:55.720 --> 0:11:00.360
<v Speaker 1>this behavior in raccoons in the wild, so I don't

0:11:00.360 --> 0:11:03.760
<v Speaker 1>know about the only in captivity part. I guess the

0:11:04.480 --> 0:11:07.800
<v Speaker 1>detail here would be that in captivity one generally has

0:11:07.920 --> 0:11:10.800
<v Speaker 1>a readily available supply of water. There is like a

0:11:10.840 --> 0:11:14.400
<v Speaker 1>dish of water, or I did just watch that cotton

0:11:14.400 --> 0:11:16.280
<v Speaker 1>candy video in the background. You know, this is a

0:11:16.320 --> 0:11:18.560
<v Speaker 1>case where it looks like it is a raccoon in

0:11:18.600 --> 0:11:22.080
<v Speaker 1>a captive environment and there is the water for it

0:11:22.120 --> 0:11:24.679
<v Speaker 1>to drink from, so it makes use of set water. Right,

0:11:24.720 --> 0:11:27.520
<v Speaker 1>That's a good point. I mean, so captivity clearly provides

0:11:28.000 --> 0:11:31.600
<v Speaker 1>the right setting and opportunities for this behavior to be observed.

0:11:31.679 --> 0:11:34.480
<v Speaker 1>So maybe if it does occur in nature or if

0:11:34.520 --> 0:11:37.040
<v Speaker 1>it doesn't, either way, we can at least admit that

0:11:37.040 --> 0:11:40.160
<v Speaker 1>the majority of the times humans are witnessing this behavior

0:11:40.200 --> 0:11:44.240
<v Speaker 1>it is in raccoons in captivity. But Lyle Watson says

0:11:44.480 --> 0:11:48.040
<v Speaker 1>before this study, opinion was divided into roughly two camps

0:11:48.080 --> 0:11:52.080
<v Speaker 1>about what the purpose of raccoon food dousing was. He

0:11:52.120 --> 0:11:55.559
<v Speaker 1>says that some researchers thought that raccoons were actually washing

0:11:55.559 --> 0:11:59.040
<v Speaker 1>their food, actively getting dirt off of it, and others

0:11:59.160 --> 0:12:01.720
<v Speaker 1>thought that they were moistening it to make it easier

0:12:01.720 --> 0:12:04.640
<v Speaker 1>to eat, you know, to essentially lubricate it for the mouth,

0:12:04.720 --> 0:12:07.880
<v Speaker 1>like we were talking about with the birds. And before

0:12:07.880 --> 0:12:10.360
<v Speaker 1>we go on to the actual experiments, I just wanted

0:12:10.400 --> 0:12:13.480
<v Speaker 1>to note something from the paper that I thought was interesting.

0:12:13.559 --> 0:12:17.960
<v Speaker 1>The author actually makes a table of observations of raccoons

0:12:17.960 --> 0:12:21.440
<v Speaker 1>eating different kinds of foods and ranks them by which

0:12:21.480 --> 0:12:25.199
<v Speaker 1>foods were doused the most often to the least often. So,

0:12:25.920 --> 0:12:27.679
<v Speaker 1>if you look at this list, the foods that were

0:12:27.679 --> 0:12:32.480
<v Speaker 1>doused the least often were things like corn oats and earthworms,

0:12:33.400 --> 0:12:38.240
<v Speaker 1>and the foods that were doused the most often were crayfish, shrimp,

0:12:38.360 --> 0:12:47.920
<v Speaker 1>water snails, land snails, crabs, locusts, cockroaches, muscles, clams, cherries, grapes, eggs,

0:12:48.040 --> 0:12:50.040
<v Speaker 1>And I'm reading down the list now, so I'm getting

0:12:50.040 --> 0:12:52.920
<v Speaker 1>to about the middle. But one thing I thought was

0:12:52.960 --> 0:12:56.480
<v Speaker 1>interesting is that a lot of the food items that

0:12:56.520 --> 0:12:59.760
<v Speaker 1>are the most doused are animals that naturally live in

0:12:59.800 --> 0:13:02.200
<v Speaker 1>the water. So I think they're being given to the raccoon,

0:13:02.360 --> 0:13:05.679
<v Speaker 1>probably already dead or out of the water when the

0:13:05.760 --> 0:13:08.560
<v Speaker 1>raccoon receives them, But the raccoon is taking them to

0:13:08.600 --> 0:13:12.319
<v Speaker 1>the water and dousing them and then eating them. Yeah, yeah,

0:13:12.360 --> 0:13:15.400
<v Speaker 1>that is notable on this this hierarchy here, though of

0:13:15.400 --> 0:13:17.520
<v Speaker 1>course you know you look at it too, and you're

0:13:18.040 --> 0:13:22.160
<v Speaker 1>thrown for a curve on why the cherries are ranked

0:13:22.160 --> 0:13:26.440
<v Speaker 1>so high, why the earthworm is ranked so low? Other

0:13:26.480 --> 0:13:28.280
<v Speaker 1>things seem to make you know a certain amount of sense,

0:13:28.440 --> 0:13:31.560
<v Speaker 1>like okay, yeah, corn is more or less good to go,

0:13:31.800 --> 0:13:34.840
<v Speaker 1>same with a pair. But so this study tried a

0:13:34.880 --> 0:13:38.199
<v Speaker 1>couple of experiments to test the reigning hypotheses, the food

0:13:38.240 --> 0:13:42.200
<v Speaker 1>moistening hypothesis, and the active cleansing hypothesis. So as far

0:13:42.240 --> 0:13:45.840
<v Speaker 1>as the cleansing hypothesis, they said, okay, what if we

0:13:45.880 --> 0:13:48.920
<v Speaker 1>try giving raccoons food that is dirty and then food

0:13:48.920 --> 0:13:51.840
<v Speaker 1>that we've already cleaned off, to see what the raccoons

0:13:51.880 --> 0:13:53.600
<v Speaker 1>do with it. Will that make a difference, like will

0:13:53.640 --> 0:13:58.040
<v Speaker 1>they clean? Will they douse dirty food more than clean food?

0:13:58.480 --> 0:14:01.680
<v Speaker 1>So this was tried with quote, small mud crabs, so

0:14:02.120 --> 0:14:03.720
<v Speaker 1>they might forge for these in the wild and you

0:14:03.760 --> 0:14:06.080
<v Speaker 1>might expect them to have mud on them. And so

0:14:06.240 --> 0:14:09.319
<v Speaker 1>raccoons in captivity were tested with clean crabs and dirty crabs,

0:14:09.360 --> 0:14:11.559
<v Speaker 1>and what do you know, it made no difference at all.

0:14:11.640 --> 0:14:15.240
<v Speaker 1>In fact, this was not a significant difference. But they

0:14:15.320 --> 0:14:19.040
<v Speaker 1>doused the clean crabs more than the muddy crabs. Yeah yeah, So,

0:14:19.080 --> 0:14:22.000
<v Speaker 1>like if you're going to be desperate with findings from

0:14:22.040 --> 0:14:26.640
<v Speaker 1>this study, like this wouldn't even back up the idea

0:14:26.680 --> 0:14:30.000
<v Speaker 1>that they're washing anything exactly. So, according to this experiment,

0:14:30.040 --> 0:14:33.120
<v Speaker 1>it makes no difference at all, just sometimes they dunk

0:14:33.120 --> 0:14:35.920
<v Speaker 1>and sometimes they don't, and it appears to have no

0:14:36.080 --> 0:14:39.720
<v Speaker 1>relationship whatsoever to the amount of mud. So that's taken

0:14:39.760 --> 0:14:42.360
<v Speaker 1>as a hit against the act of cleansing hypothesis. But

0:14:42.440 --> 0:14:45.960
<v Speaker 1>what about the moistening action idea? So what if the

0:14:45.960 --> 0:14:48.440
<v Speaker 1>point of dowsing is too is that wet food is

0:14:48.480 --> 0:14:51.840
<v Speaker 1>easier to eat? Well, they tested this with an experiment

0:14:51.920 --> 0:14:55.520
<v Speaker 1>as well. So Lyle Watson says there was a series

0:14:55.560 --> 0:14:59.160
<v Speaker 1>of three trials with the choices between dry dog biscuits,

0:14:59.280 --> 0:15:03.040
<v Speaker 1>dried shrim and similar objects which had been soaked in water,

0:15:03.600 --> 0:15:06.880
<v Speaker 1>and the result was again the raccoons showed no significant

0:15:06.920 --> 0:15:09.920
<v Speaker 1>difference at all. They were just as likely to duncan

0:15:10.040 --> 0:15:13.600
<v Speaker 1>dous wet food objects as they were to douse dry ones.

0:15:14.760 --> 0:15:17.840
<v Speaker 1>So both of the active hypotheses at the time of

0:15:17.840 --> 0:15:20.600
<v Speaker 1>the study in nineteen sixty three were disconfirmed by the

0:15:20.640 --> 0:15:24.840
<v Speaker 1>experiments that Lyle Watson did. So what does the author

0:15:24.880 --> 0:15:29.080
<v Speaker 1>here think that the dowsing is actually for Well, he

0:15:29.120 --> 0:15:31.760
<v Speaker 1>has an interesting idea. Of course this is not conclusive,

0:15:31.760 --> 0:15:35.360
<v Speaker 1>but this is his interpretation. He says that the best

0:15:35.400 --> 0:15:39.280
<v Speaker 1>explanation is that raccoon dowsing of food is quote, an

0:15:39.480 --> 0:15:43.880
<v Speaker 1>artificial creation of a natural situation whose function is to

0:15:43.960 --> 0:15:48.560
<v Speaker 1>allow the expression of a thwarted independent feeding mechanism. So

0:15:48.600 --> 0:15:51.440
<v Speaker 1>I think what he means by this is that a raccoon,

0:15:51.960 --> 0:15:55.640
<v Speaker 1>when dousing food, is going through the motions of an

0:15:55.680 --> 0:16:01.800
<v Speaker 1>instinctual water based foraging or hunting strategy. That is, that

0:16:01.960 --> 0:16:04.360
<v Speaker 1>is naturally rewarding, you know, in the same way that

0:16:04.360 --> 0:16:07.400
<v Speaker 1>that hunting or foraging behaviors are to all kinds of animals.

0:16:07.400 --> 0:16:10.960
<v Speaker 1>You know, we're motivated to do them, and it's rewarding

0:16:11.000 --> 0:16:15.040
<v Speaker 1>to the raccoon's brain and associated with the acquisition of food,

0:16:15.480 --> 0:16:19.760
<v Speaker 1>even though in these captive scenarios it's not actually doing anything.

0:16:21.120 --> 0:16:24.640
<v Speaker 1>Now that's interest, because that would mean it's not adaptive. Well,

0:16:24.680 --> 0:16:27.240
<v Speaker 1>it would be it would be adaptive that a raccoon

0:16:27.280 --> 0:16:29.880
<v Speaker 1>has a natural desire to like fish around in the

0:16:29.920 --> 0:16:34.240
<v Speaker 1>water for food items, but that maybe this urge is

0:16:34.280 --> 0:16:36.960
<v Speaker 1>so strong it's coming through even in moments where it

0:16:37.040 --> 0:16:41.440
<v Speaker 1>doesn't actually need to forage. It's just satisfying and overwhelming desire.

0:16:41.640 --> 0:16:44.760
<v Speaker 1>And he gives a comparison. So what Watson says his quote,

0:16:45.160 --> 0:16:48.200
<v Speaker 1>the raccoon's behavior is perhaps most closely related to what

0:16:48.280 --> 0:16:52.960
<v Speaker 1>may be called the quote revitalizing behavior of certain feliday cats.

0:16:53.520 --> 0:16:56.920
<v Speaker 1>A captive cat whose hunting patterns of behavior are starved

0:16:56.960 --> 0:16:59.520
<v Speaker 1>by virtue of the fact that all food is presented

0:16:59.600 --> 0:17:04.400
<v Speaker 1>dead will artificially create the opportunity to satisfy these responses

0:17:04.680 --> 0:17:07.560
<v Speaker 1>by throwing a dead bird into the air and quote

0:17:07.640 --> 0:17:10.439
<v Speaker 1>giving it life in order that it may be hunted

0:17:10.480 --> 0:17:13.919
<v Speaker 1>down and caught before being eaten. This has been particularly

0:17:13.960 --> 0:17:17.280
<v Speaker 1>well observed in the Golden Cat or feel us Taminki

0:17:17.640 --> 0:17:21.080
<v Speaker 1>at the London Zoo and so yeah, in the same

0:17:21.119 --> 0:17:24.320
<v Speaker 1>way that you might see a cat that doesn't actually

0:17:24.359 --> 0:17:27.840
<v Speaker 1>need to hunt, kind of batting a food item or

0:17:27.880 --> 0:17:31.080
<v Speaker 1>even like a dead mouse around as if like it's

0:17:31.080 --> 0:17:34.560
<v Speaker 1>still alive, and maybe the cat is trying to satisfy

0:17:34.640 --> 0:17:38.639
<v Speaker 1>some need for hunting behaviors just because the hunting behaviors

0:17:38.680 --> 0:17:43.120
<v Speaker 1>are instinctually rewarding. Perhaps the raccoon is doing something similar

0:17:43.440 --> 0:17:46.399
<v Speaker 1>by fishing around for a food item that it actually

0:17:46.440 --> 0:17:50.320
<v Speaker 1>already has in possession in the water m okay, and

0:17:51.480 --> 0:17:54.520
<v Speaker 1>so in this it would be comparable to like the

0:17:54.560 --> 0:17:57.080
<v Speaker 1>play we observe in cats. We think of it as play.

0:17:57.160 --> 0:17:59.400
<v Speaker 1>They're playing with a toy, But it's of course hunting

0:17:59.400 --> 0:18:02.960
<v Speaker 1>instinct that you know that they've they're highly evolved to

0:18:03.160 --> 0:18:07.120
<v Speaker 1>partake in. And if it's even though there's nothing live

0:18:07.240 --> 0:18:10.760
<v Speaker 1>running around your living room, they need to engage in

0:18:10.760 --> 0:18:13.720
<v Speaker 1>that kind of activity anyway, right, They have an instinctual

0:18:13.840 --> 0:18:18.440
<v Speaker 1>drive for hunting behaviors. They can't actually hunt in their

0:18:18.520 --> 0:18:21.639
<v Speaker 1>environment because there's nothing to hunt, so they kind of

0:18:21.720 --> 0:18:24.840
<v Speaker 1>hunt in superfluous ways, hunt in ways that are not

0:18:24.920 --> 0:18:29.080
<v Speaker 1>really necessary and so and so. Lyle Watson links this

0:18:29.160 --> 0:18:32.040
<v Speaker 1>to the idea that this behavior is primarily observed or

0:18:32.080 --> 0:18:36.040
<v Speaker 1>in his in his belief, only observed in raccoons in captivity.

0:18:36.359 --> 0:18:39.080
<v Speaker 1>You know, normally they'd be out fishing around for crayfish

0:18:39.119 --> 0:18:42.879
<v Speaker 1>and crabs and stuff in the water. In captivity, they

0:18:42.880 --> 0:18:45.879
<v Speaker 1>don't have to do that, so they satisfy this drive

0:18:46.000 --> 0:18:49.680
<v Speaker 1>by swishing their food items around in the water. I've

0:18:49.840 --> 0:18:52.359
<v Speaker 1>I remember hearing before that the like the hands of

0:18:52.400 --> 0:18:56.080
<v Speaker 1>the raccoon are extremely subtle, yes, and that they're not

0:18:56.119 --> 0:18:59.040
<v Speaker 1>affected by the like they can reach into cold water

0:18:59.080 --> 0:19:01.520
<v Speaker 1>and feel around in cold waters with a tolerance that

0:19:02.160 --> 0:19:05.760
<v Speaker 1>humans are completely incapable of, and that their feeling of

0:19:05.800 --> 0:19:09.840
<v Speaker 1>things in the water is more in line with like

0:19:09.920 --> 0:19:12.760
<v Speaker 1>human sight, Like that's how sensitive their little hands are.

0:19:13.480 --> 0:19:19.720
<v Speaker 1>So yeah, the sense experience of this, it makes sense

0:19:19.720 --> 0:19:22.640
<v Speaker 1>when you think about like this, this sort of advanced

0:19:23.720 --> 0:19:27.480
<v Speaker 1>grasping that's going on, this advanced sense of touch. Well,

0:19:27.520 --> 0:19:29.080
<v Speaker 1>that's actually the next thing I was going to get

0:19:29.080 --> 0:19:32.719
<v Speaker 1>to that. That is the The other hypothesis that seems

0:19:32.720 --> 0:19:37.320
<v Speaker 1>to be live about why raccoons douse their food is

0:19:37.359 --> 0:19:41.480
<v Speaker 1>the idea that somehow it hyper charges the sensory abilities

0:19:41.520 --> 0:19:44.680
<v Speaker 1>of their paws. And exactly like you're saying, raccoons are

0:19:45.320 --> 0:19:48.840
<v Speaker 1>known in the animal world for having incredibly sensitive fore paws.

0:19:49.080 --> 0:19:52.760
<v Speaker 1>Apparently they gather a large proportion of their sensations of

0:19:52.760 --> 0:19:55.919
<v Speaker 1>the world through touch, and of course this is very

0:19:56.040 --> 0:19:58.840
<v Speaker 1>useful if you're an animal that's like rooting around in

0:19:58.920 --> 0:20:01.480
<v Speaker 1>muddy water for for prey. You know, you want to

0:20:01.480 --> 0:20:03.639
<v Speaker 1>be able to get a lot of information by the

0:20:03.960 --> 0:20:07.680
<v Speaker 1>pads on your forepaws, on your hands and fingers, and

0:20:07.720 --> 0:20:11.720
<v Speaker 1>so it has been argued that maybe the dowsing behavior

0:20:12.000 --> 0:20:15.800
<v Speaker 1>is related to the hypersensitivity of their fore paws and

0:20:15.840 --> 0:20:19.159
<v Speaker 1>the importance of the sensory information they get there. So

0:20:19.240 --> 0:20:23.240
<v Speaker 1>perhaps moistening of the fore paws actually makes them more

0:20:23.480 --> 0:20:28.120
<v Speaker 1>sensitive to textual information about the food in hand. So

0:20:28.160 --> 0:20:30.800
<v Speaker 1>if this hypothesis were correct, it would be that dousing

0:20:30.880 --> 0:20:34.760
<v Speaker 1>serves the purpose of letting the raccoon get better sensory

0:20:34.840 --> 0:20:38.400
<v Speaker 1>information about the food they are about to eat in

0:20:38.480 --> 0:20:41.960
<v Speaker 1>the type of since realm that is most relevant to them,

0:20:42.000 --> 0:20:44.360
<v Speaker 1>which is touch. So it would be sort of similar

0:20:44.359 --> 0:20:47.160
<v Speaker 1>to a human looking at a morsel of food by

0:20:47.160 --> 0:20:49.000
<v Speaker 1>holding it up to the light so they could get

0:20:49.000 --> 0:20:51.120
<v Speaker 1>a better look at it. Or you know, a dog

0:20:51.280 --> 0:20:53.840
<v Speaker 1>really going to town sniffing a piece of food before

0:20:53.880 --> 0:20:56.879
<v Speaker 1>they eat it. That it would be a specialized sense

0:20:56.920 --> 0:21:00.639
<v Speaker 1>heightening behavior that is particular to the sense regime of

0:21:00.680 --> 0:21:03.640
<v Speaker 1>the raccoon. Oh now this yeah, this makes a lot

0:21:03.640 --> 0:21:05.680
<v Speaker 1>of sense, and at the same time, it also makes

0:21:05.680 --> 0:21:09.560
<v Speaker 1>that cotton candy video all the more heartbreaking because it

0:21:09.640 --> 0:21:13.439
<v Speaker 1>really wanted to understand this. This uh, this sugary concoction.

0:21:13.840 --> 0:21:16.879
<v Speaker 1>What is this thing? Well, let me douse it in

0:21:16.880 --> 0:21:18.800
<v Speaker 1>the water and feel it a little bit more. What

0:21:19.520 --> 0:21:22.159
<v Speaker 1>now it is completely gone? Now I have I know

0:21:22.240 --> 0:21:24.760
<v Speaker 1>even less about it than I did before. But anyway,

0:21:24.920 --> 0:21:27.399
<v Speaker 1>I'm intrigued by both of these hypotheses. I don't know

0:21:27.480 --> 0:21:29.520
<v Speaker 1>which one I would lean more toward the sort of

0:21:29.960 --> 0:21:33.679
<v Speaker 1>the hypercharging sensory data from the from the hands or

0:21:33.720 --> 0:21:39.520
<v Speaker 1>the thwarted natural foraging behavior. Both seem possible to me

0:21:39.560 --> 0:21:42.040
<v Speaker 1>based on what I've read. The interesting thing about the

0:21:42.080 --> 0:21:46.520
<v Speaker 1>idea of a thwarted foraging behavior is that it would

0:21:46.560 --> 0:21:49.400
<v Speaker 1>seem to connect to that list of foods that are

0:21:49.440 --> 0:21:52.080
<v Speaker 1>doused most often, that the top of the list was

0:21:52.160 --> 0:21:56.520
<v Speaker 1>all like aquatic animals that the raccoon would naturally forage

0:21:56.560 --> 0:22:05.880
<v Speaker 1>for in the creeks and in the mud. But Rob,

0:22:05.920 --> 0:22:08.000
<v Speaker 1>if you're ready, I would actually like to turn to

0:22:08.200 --> 0:22:11.399
<v Speaker 1>another example of animals doing something to their food that

0:22:11.640 --> 0:22:15.800
<v Speaker 1>looks like washing but has been hypothesized to have a

0:22:15.840 --> 0:22:21.560
<v Speaker 1>different purpose altogether. And this is related to seasoning. So

0:22:21.680 --> 0:22:25.639
<v Speaker 1>in the last episode we spoken whispers of horror about

0:22:25.680 --> 0:22:29.040
<v Speaker 1>the idea of eating an unseasoned potato. You know, potatoes

0:22:29.080 --> 0:22:33.040
<v Speaker 1>are great, They really need some salt and pepper, hopefully

0:22:33.119 --> 0:22:36.320
<v Speaker 1>some fat of some kind, butter oil or something to

0:22:36.480 --> 0:22:39.320
<v Speaker 1>take them to their full potential. Just the thought of

0:22:39.359 --> 0:22:46.400
<v Speaker 1>a completely unseasoned cooked potato is very unappetizing. Yeah, even

0:22:46.440 --> 0:22:48.480
<v Speaker 1>if you have one of those those really good potatoes,

0:22:48.520 --> 0:22:51.680
<v Speaker 1>you know, like those fingerlings, and the purple potatoes, and

0:22:51.880 --> 0:22:54.920
<v Speaker 1>of course sweet potatoes. Even then they need a little something.

0:22:54.960 --> 0:22:57.800
<v Speaker 1>And if you get into the realm of the Russets

0:22:57.840 --> 0:23:00.280
<v Speaker 1>all the more. Now, as always, of course, you know,

0:23:00.600 --> 0:23:04.199
<v Speaker 1>our food preferences could be just cultural preferences. But I

0:23:04.200 --> 0:23:07.480
<v Speaker 1>think it's clear that a really important part of human

0:23:07.560 --> 0:23:11.760
<v Speaker 1>cuisine in general is seasoning. Maybe not to the same

0:23:11.800 --> 0:23:14.440
<v Speaker 1>extent in every single culture in the world, but broadly

0:23:14.480 --> 0:23:17.440
<v Speaker 1>all over the planet. People like to season their food,

0:23:18.000 --> 0:23:21.840
<v Speaker 1>and seasoning amounts to augmenting the natural flavors of bulk

0:23:21.880 --> 0:23:26.960
<v Speaker 1>food stuffs in our diet with highly flavor relevant little

0:23:27.040 --> 0:23:30.800
<v Speaker 1>little bits of ingredients, usually things like herbs, spices, and

0:23:30.920 --> 0:23:34.639
<v Speaker 1>probably most importantly of all, salt. Now there's a reason

0:23:34.760 --> 0:23:36.840
<v Speaker 1>humans have a taste for salt. Salt is not just

0:23:36.960 --> 0:23:40.399
<v Speaker 1>a nice to have. It is biologically essential, not in

0:23:40.440 --> 0:23:44.000
<v Speaker 1>the quantities that we Americans eat it. You know that

0:23:44.119 --> 0:23:47.840
<v Speaker 1>we weigh more salt than we need. But you've got

0:23:47.840 --> 0:23:50.359
<v Speaker 1>to have some salt. Without any salt, you would be

0:23:50.400 --> 0:23:53.119
<v Speaker 1>in a bad place. And we talked about this to

0:23:53.160 --> 0:23:56.199
<v Speaker 1>some extent in our episodes about the science of thirst. Remember,

0:23:56.480 --> 0:23:58.080
<v Speaker 1>you know the things about how you've got to have

0:23:58.119 --> 0:24:01.879
<v Speaker 1>the right balance of osmala in your blood. Like the

0:24:02.160 --> 0:24:06.679
<v Speaker 1>amount of substances, especially salt, dissolved in the blood is

0:24:06.720 --> 0:24:10.040
<v Speaker 1>relevant to the functioning of cells. Without salt, your body

0:24:10.080 --> 0:24:13.800
<v Speaker 1>just doesn't really work. You need some salt. Yeah, And likewise,

0:24:13.920 --> 0:24:16.800
<v Speaker 1>you're cooking a stew or a soup or just about anything,

0:24:17.400 --> 0:24:20.119
<v Speaker 1>you often find yourself in that situation where you're adding

0:24:20.160 --> 0:24:22.560
<v Speaker 1>salt to taste, and you know it's like, oh, it's

0:24:22.560 --> 0:24:24.640
<v Speaker 1>not quite there yet a little more salt, not quite there,

0:24:24.680 --> 0:24:26.560
<v Speaker 1>a little bit more salt. But the closer you get,

0:24:27.440 --> 0:24:29.680
<v Speaker 1>the more stressful it can become, because you know that

0:24:29.720 --> 0:24:32.960
<v Speaker 1>if you oversalt it, there's not an easy way back.

0:24:33.000 --> 0:24:35.080
<v Speaker 1>There may not be a way back. That is a

0:24:35.160 --> 0:24:37.880
<v Speaker 1>very good point. Especially, Yeah, if it's like one homogeneous

0:24:37.920 --> 0:24:40.200
<v Speaker 1>mass of food, like like a soup or something, it's

0:24:40.240 --> 0:24:42.240
<v Speaker 1>it's really hard to take the take the salt out,

0:24:42.240 --> 0:24:44.400
<v Speaker 1>I guess, unless you just dilute it by adding more

0:24:44.400 --> 0:24:46.640
<v Speaker 1>water or something, but then you screw up the other

0:24:46.680 --> 0:24:49.639
<v Speaker 1>flavor ratios. Yeah, it's just you don't want to over salt.

0:24:49.760 --> 0:24:53.359
<v Speaker 1>That's that's hard to fix. Yeah, baby steps. Now, lots

0:24:53.359 --> 0:24:55.760
<v Speaker 1>of foods that we would find in the natural environment

0:24:55.840 --> 0:24:59.720
<v Speaker 1>already have some salt content. You know, vegetables already have

0:24:59.720 --> 0:25:02.040
<v Speaker 1>salt to them. If you you know, like a like

0:25:02.080 --> 0:25:05.199
<v Speaker 1>a stalk of celery actually is, you can almost taste

0:25:05.320 --> 0:25:08.239
<v Speaker 1>that celery is naturally a little bit salty. You can

0:25:08.320 --> 0:25:11.160
<v Speaker 1>sort of taste the sodium in there. Of course, meat

0:25:11.240 --> 0:25:14.160
<v Speaker 1>already has salt in it naturally. Most people would add

0:25:14.200 --> 0:25:17.560
<v Speaker 1>more salt to season it, but it has some sodium

0:25:17.600 --> 0:25:21.639
<v Speaker 1>content there already, But we want more. And why is

0:25:21.680 --> 0:25:23.600
<v Speaker 1>it that we want more as well? It's because the

0:25:23.640 --> 0:25:26.439
<v Speaker 1>concentrations of salt that we naturally find in meat and

0:25:26.520 --> 0:25:29.840
<v Speaker 1>plants in the environment, it's fairly low, and salt is

0:25:29.920 --> 0:25:33.400
<v Speaker 1>necessary for survival, so our bodies are shaped by evolution

0:25:33.440 --> 0:25:35.920
<v Speaker 1>to seek out extra salt. However, we can get it,

0:25:36.520 --> 0:25:39.800
<v Speaker 1>and lots of animals acquire salt not just from food,

0:25:39.960 --> 0:25:44.439
<v Speaker 1>but from mineral reservoirs known as salt licks or more accurately,

0:25:44.520 --> 0:25:48.240
<v Speaker 1>mineral licks. Again, because salt can, in the neurosense, be

0:25:48.320 --> 0:25:51.840
<v Speaker 1>taken to imply just sodium chloride, and sodium is not

0:25:51.880 --> 0:25:55.160
<v Speaker 1>the only electrolyte or mineral that animals need to supplement

0:25:55.160 --> 0:25:58.920
<v Speaker 1>in this way. Animals are also looking for calcium, iron,

0:25:59.240 --> 0:26:02.840
<v Speaker 1>zinc foss for us and so forth. But the idea

0:26:02.840 --> 0:26:05.000
<v Speaker 1>of a salt lick is interesting to me because I

0:26:05.080 --> 0:26:07.800
<v Speaker 1>was reading about them, and what I had always pictured

0:26:07.800 --> 0:26:09.760
<v Speaker 1>for a salt lick when I was growing up was

0:26:09.960 --> 0:26:13.800
<v Speaker 1>that there's a deer, specifically a deer, and it's licking

0:26:13.840 --> 0:26:17.760
<v Speaker 1>a white rock that has the desired minerals on its surface.

0:26:18.240 --> 0:26:21.760
<v Speaker 1>And while this scenario does happen, apparently a lot of times,

0:26:21.760 --> 0:26:25.040
<v Speaker 1>a mineral lick can also consist of a place where

0:26:25.080 --> 0:26:28.199
<v Speaker 1>animals come to sort of eat dirt or mud or

0:26:28.240 --> 0:26:31.399
<v Speaker 1>clay that has the molecules they're looking for. But of

0:26:31.400 --> 0:26:33.760
<v Speaker 1>course humans do something pretty interesting, which is that we

0:26:33.880 --> 0:26:38.959
<v Speaker 1>combine the quest for supplemental salt with the broader quest

0:26:39.040 --> 0:26:44.520
<v Speaker 1>for nutrition by salting food directly. The result is clearly

0:26:44.520 --> 0:26:46.640
<v Speaker 1>more than the sum of its parts, because, after all,

0:26:46.640 --> 0:26:50.600
<v Speaker 1>salt doesn't just make food taste saltier. I think humans

0:26:51.000 --> 0:26:54.200
<v Speaker 1>mostly know from experience that it makes food taste more

0:26:54.320 --> 0:26:57.880
<v Speaker 1>like itself. A little bit of salt seems to magnify

0:26:57.960 --> 0:27:01.560
<v Speaker 1>the natural flavors present in whatever you're eating, So salt

0:27:01.680 --> 0:27:05.680
<v Speaker 1>makes chocolate taste more like chocolate, and salt makes broccoli

0:27:05.720 --> 0:27:10.680
<v Speaker 1>taste more like broccoli. It's just a general flavor intensifier. Yeah,

0:27:10.720 --> 0:27:13.439
<v Speaker 1>even things that don't need salt at all, Like a

0:27:13.520 --> 0:27:17.600
<v Speaker 1>really good slice of watermelon is perfect on its own,

0:27:17.680 --> 0:27:20.200
<v Speaker 1>and yet sprinkle a little salt on there, and you've

0:27:20.200 --> 0:27:23.879
<v Speaker 1>managed to intensify even that. Yeah, it becomes hyper watermelon.

0:27:24.760 --> 0:27:28.200
<v Speaker 1>And because of these obvious you know, sensory and pleasure benefits.

0:27:28.480 --> 0:27:31.560
<v Speaker 1>The complement of supplemental salt to food. You might wonder

0:27:31.640 --> 0:27:35.119
<v Speaker 1>we'll do any non human animals season their food like

0:27:35.200 --> 0:27:38.360
<v Speaker 1>we do? Do they combine the quest for food with

0:27:38.440 --> 0:27:42.199
<v Speaker 1>the quest for supplemental salt into a single consumption activity.

0:27:42.920 --> 0:27:45.879
<v Speaker 1>And you might assume no, But I came across a

0:27:45.960 --> 0:27:48.480
<v Speaker 1>really interesting surprise here. So I want to turn to

0:27:48.640 --> 0:27:52.680
<v Speaker 1>a actually rather famous episode in the history of primatology,

0:27:53.000 --> 0:27:55.560
<v Speaker 1>but famous for a different reason than we're going to

0:27:55.600 --> 0:27:58.360
<v Speaker 1>be talking about it, and that is the potato washing

0:27:58.480 --> 0:28:02.399
<v Speaker 1>monkeys of Koshima Eye and in Japan. Rob, Have you

0:28:02.400 --> 0:28:05.280
<v Speaker 1>ever heard about these before? I don't believe I had.

0:28:07.480 --> 0:28:10.639
<v Speaker 1>Some of this came up in my research, but I

0:28:10.720 --> 0:28:14.000
<v Speaker 1>knew that you had the primates firmly in your side here. Well,

0:28:14.000 --> 0:28:16.520
<v Speaker 1>I want to briefly mention side a couple of papers

0:28:16.560 --> 0:28:18.440
<v Speaker 1>as sources here for what I'm about to talk about.

0:28:18.480 --> 0:28:22.080
<v Speaker 1>One is by Massau Kawai called Newly Acquired pre Cultural

0:28:22.080 --> 0:28:26.359
<v Speaker 1>Behavior in the Natural Troop of Japanese Monkeys of on

0:28:26.480 --> 0:28:30.000
<v Speaker 1>Koshima inlet in the journal Primates in nineteen sixty five.

0:28:30.640 --> 0:28:34.240
<v Speaker 1>And then the other one is a book chapter called

0:28:35.000 --> 0:28:40.000
<v Speaker 1>Sweet Potato Washing revisited by Satoshi Hirada, Kunio Watanabe, and

0:28:40.200 --> 0:28:43.160
<v Speaker 1>Kawai Massau. The last author is the same as the

0:28:43.360 --> 0:28:46.640
<v Speaker 1>author of the paper from the sixties. This was published

0:28:46.720 --> 0:28:49.880
<v Speaker 1>in Primate Origins of Human Cognition and Behavior in two

0:28:49.920 --> 0:28:53.240
<v Speaker 1>thousand and eight. So, first of all, one thing we

0:28:53.240 --> 0:28:55.880
<v Speaker 1>should say is that everything we're about to describe is

0:28:55.920 --> 0:29:00.320
<v Speaker 1>not a behavior observed purely spontaneously in the wild, one

0:29:00.360 --> 0:29:03.440
<v Speaker 1>that is, at least in part a result of human intervention.

0:29:03.560 --> 0:29:06.640
<v Speaker 1>So the entire story here comes with that caveat, but

0:29:06.680 --> 0:29:10.480
<v Speaker 1>it's very interesting nonetheless. So on the island of Koshima

0:29:10.520 --> 0:29:14.000
<v Speaker 1>in Japan, there are native populations of a monkey called

0:29:14.480 --> 0:29:17.479
<v Speaker 1>the scientific name is Macaca fuscata, also known as the

0:29:17.600 --> 0:29:21.080
<v Speaker 1>Japanese macaque or the snow monkey. You never seen one

0:29:21.080 --> 0:29:22.760
<v Speaker 1>of these, you should look them up. I think they're

0:29:22.840 --> 0:29:25.760
<v Speaker 1>very cute they are. They're quite cute. They're very soft

0:29:25.800 --> 0:29:29.720
<v Speaker 1>looking fur. I know one shouldn't feel this way about

0:29:29.760 --> 0:29:32.920
<v Speaker 1>wild animals, but I want to pet them. But anyway,

0:29:32.960 --> 0:29:37.400
<v Speaker 1>Beginning with some papers published by a scientist named Shunzo

0:29:37.480 --> 0:29:42.240
<v Speaker 1>Kawamura in the nineteen fifties, researchers began to document an

0:29:42.280 --> 0:29:46.280
<v Speaker 1>interesting behavior among a single troop of monkeys on Koshima Island,

0:29:46.560 --> 0:29:49.640
<v Speaker 1>and it was washing their food. So the history went

0:29:49.720 --> 0:29:54.280
<v Speaker 1>like this. In the early nineteen fifties, several Japanese researchers

0:29:54.360 --> 0:29:57.800
<v Speaker 1>began providing food in the form of sweet potato pieces

0:29:58.200 --> 0:30:00.280
<v Speaker 1>to the monkeys on the island, and I read in

0:30:00.320 --> 0:30:04.240
<v Speaker 1>a book passage elsewhere that the original purpose of giving

0:30:04.240 --> 0:30:07.360
<v Speaker 1>them the food like this was to lure the monkeys

0:30:07.360 --> 0:30:10.320
<v Speaker 1>out into an open space near the waterfront where it

0:30:10.320 --> 0:30:12.920
<v Speaker 1>would be easier for the researchers to watch them to

0:30:12.960 --> 0:30:15.800
<v Speaker 1>observe their behavior. And I think part of the intended

0:30:15.800 --> 0:30:19.920
<v Speaker 1>significance of this study was that the scientists would end

0:30:20.000 --> 0:30:24.000
<v Speaker 1>up making long, multigenerational observations of the same monkey troop,

0:30:24.400 --> 0:30:27.920
<v Speaker 1>with individuals in the troop named and differentiated so that

0:30:27.920 --> 0:30:31.840
<v Speaker 1>their individual behaviors could be documented. But of course, the

0:30:31.840 --> 0:30:34.920
<v Speaker 1>monkeys liked the extra food. They liked the sweet potato pieces.

0:30:35.480 --> 0:30:38.840
<v Speaker 1>But the real twist came in September of nineteen fifty

0:30:38.840 --> 0:30:41.960
<v Speaker 1>three when a young monkey, a one and a half

0:30:42.040 --> 0:30:46.520
<v Speaker 1>year old female named Emo, appeared to have invented a

0:30:46.560 --> 0:30:51.480
<v Speaker 1>new behavior. She washed her potato. And now washing was

0:30:51.600 --> 0:30:55.080
<v Speaker 1>not previously part of the behavioral repertoire of these monkeys,

0:30:55.200 --> 0:30:58.840
<v Speaker 1>but apparently Emo was reacting to the fact that these

0:30:58.840 --> 0:31:01.680
<v Speaker 1>sweet potato pieces left out on the ground, they would

0:31:01.680 --> 0:31:04.200
<v Speaker 1>get covered in sand and dirt, which, even if you're

0:31:04.200 --> 0:31:06.800
<v Speaker 1>a monkey, is apparently not the best thing to eat.

0:31:07.400 --> 0:31:11.760
<v Speaker 1>So in September nineteen fifty three, Emo started washing the

0:31:11.760 --> 0:31:15.920
<v Speaker 1>sweet potatoes. So the standard sweet potato washing behavior is

0:31:15.960 --> 0:31:19.320
<v Speaker 1>described as the monkey taking a sweet potato piece to

0:31:19.520 --> 0:31:23.720
<v Speaker 1>the edge of the water and then dipping the potato

0:31:23.880 --> 0:31:26.360
<v Speaker 1>into the water, holding it in one hand, and then

0:31:26.440 --> 0:31:30.160
<v Speaker 1>removing the sand or grit by brushing the potato under

0:31:30.200 --> 0:31:34.080
<v Speaker 1>the water with the other hand. This potato washing behavior

0:31:34.200 --> 0:31:37.640
<v Speaker 1>became famous because it was taken as evidence of the

0:31:37.720 --> 0:31:42.800
<v Speaker 1>existence of quote culture in non human animals. Because, again

0:31:42.840 --> 0:31:45.960
<v Speaker 1>according to mess El Kawai in the paper from sixty five,

0:31:46.600 --> 0:31:50.640
<v Speaker 1>by nineteen fifty six eleven monkeys in the troop had

0:31:50.680 --> 0:31:56.200
<v Speaker 1>acquired the behavior and had themselves become potato washers, and

0:31:56.280 --> 0:31:59.560
<v Speaker 1>across subsequent research periods after that, the behavior continued to

0:31:59.600 --> 0:32:01.840
<v Speaker 1>spread to more and more of the troop. Now, we

0:32:01.880 --> 0:32:04.000
<v Speaker 1>could probably come back into a whole episode on the

0:32:04.040 --> 0:32:06.920
<v Speaker 1>idea of whether this should be viewed as analogous to

0:32:07.200 --> 0:32:10.120
<v Speaker 1>human culture. But on its face, it seems to have

0:32:10.120 --> 0:32:12.160
<v Speaker 1>a lot of properties that look like culture. It's a

0:32:12.200 --> 0:32:15.920
<v Speaker 1>behavior that is not instinctual to the animal, but is

0:32:16.000 --> 0:32:19.880
<v Speaker 1>learned and then is spread apparently from one individual to

0:32:19.960 --> 0:32:22.600
<v Speaker 1>the other in the troop through a process of copying,

0:32:22.960 --> 0:32:27.000
<v Speaker 1>eventually becoming the norm for the entire animal troop. But then,

0:32:27.040 --> 0:32:29.280
<v Speaker 1>on the other hand, they're interesting questions about this and

0:32:29.600 --> 0:32:32.680
<v Speaker 1>indifferences from how we normally think of culture. For one

0:32:32.680 --> 0:32:34.800
<v Speaker 1>thing I thought was kind of interesting in this instance,

0:32:35.600 --> 0:32:38.560
<v Speaker 1>the learning process seemed to work backwards from the way

0:32:38.640 --> 0:32:42.160
<v Speaker 1>human culture is presumed to pass across generations, because it

0:32:42.200 --> 0:32:45.680
<v Speaker 1>looks like sweet potato washing started with younger monkeys and

0:32:45.760 --> 0:32:48.640
<v Speaker 1>gradually spread to the older ones. Like they said that

0:32:49.040 --> 0:32:54.480
<v Speaker 1>Emo's mother apparently learned the potato washing behavior from Emo. Oh, well,

0:32:54.520 --> 0:32:58.720
<v Speaker 1>I mean we mentioned TikTok trends earlier. Oh yeah, okay,

0:32:58.760 --> 0:33:03.000
<v Speaker 1>and you know, TikTok trends are often associated with youth culture,

0:33:03.440 --> 0:33:05.120
<v Speaker 1>so that could be a case, there could be a

0:33:05.120 --> 0:33:06.640
<v Speaker 1>case to be made. Well, yeah, you do have things

0:33:06.640 --> 0:33:09.040
<v Speaker 1>that originate with the young people, with the youth, and

0:33:09.080 --> 0:33:13.240
<v Speaker 1>then they are passed upward to older members of a

0:33:13.400 --> 0:33:16.320
<v Speaker 1>population of a culture. I guess. So, yeah, maybe it's

0:33:16.360 --> 0:33:20.080
<v Speaker 1>the youth innovate and then the elders educate. But then

0:33:20.120 --> 0:33:23.040
<v Speaker 1>certainly it does. It does run counter to the sort

0:33:23.040 --> 0:33:26.280
<v Speaker 1>of idea of elders in a given group saying this

0:33:26.440 --> 0:33:29.320
<v Speaker 1>is the way, this is the way we handle potatoes,

0:33:29.320 --> 0:33:32.440
<v Speaker 1>this is the way we wash potatoes. Obey me, younglings.

0:33:32.760 --> 0:33:34.560
<v Speaker 1>But but here's where we're about to get to the

0:33:34.560 --> 0:33:37.680
<v Speaker 1>part that's relevant to the idea of animals seasoning food.

0:33:37.880 --> 0:33:40.560
<v Speaker 1>So I wanted to read a passage from that paper

0:33:40.600 --> 0:33:44.520
<v Speaker 1>by Kawai in nineteen sixty five. The background of this

0:33:44.600 --> 0:33:48.200
<v Speaker 1>section is that the author is describing two distinct variants

0:33:48.280 --> 0:33:51.920
<v Speaker 1>of sweet potato washing behavior, one in which the sweet

0:33:51.920 --> 0:33:54.720
<v Speaker 1>potato is like I described a minute ago, dipped into

0:33:54.760 --> 0:33:57.040
<v Speaker 1>the water with one hand and then brushed with the

0:33:57.080 --> 0:34:00.320
<v Speaker 1>other hand to remove sand. The other variant is known

0:34:00.360 --> 0:34:03.920
<v Speaker 1>as quote rolling, and it consists of letting the sweet

0:34:03.920 --> 0:34:07.000
<v Speaker 1>potato drop into the shallow part of the water and

0:34:07.040 --> 0:34:09.800
<v Speaker 1>then rolling it back and forth with one hand before

0:34:09.840 --> 0:34:13.720
<v Speaker 1>retrieving and eating it. But now, to read from massau

0:34:13.800 --> 0:34:18.520
<v Speaker 1>Kawai quote but during the second period, a third type appeared.

0:34:18.920 --> 0:34:22.320
<v Speaker 1>It consisted in dipping the potato into the water every

0:34:22.360 --> 0:34:26.360
<v Speaker 1>time after knowing it once or twice. This behavior seems

0:34:26.440 --> 0:34:29.760
<v Speaker 1>quite different from brushing the sand off from the potato.

0:34:30.200 --> 0:34:34.000
<v Speaker 1>They collect potatoes and take them to the seashore. But

0:34:34.040 --> 0:34:36.480
<v Speaker 1>if this is not for the purpose of washing, what

0:34:36.600 --> 0:34:40.120
<v Speaker 1>reason is there in this behavior except for seasoning the

0:34:40.200 --> 0:34:44.520
<v Speaker 1>potatoes with saltwater. Therefore, I will call this behavior the

0:34:44.640 --> 0:34:50.160
<v Speaker 1>seasoning behavior. Huh So, obviously the behavior of repeatedly dipping

0:34:50.160 --> 0:34:53.520
<v Speaker 1>the sweet potato into saltwater every time the monkey takes

0:34:53.520 --> 0:34:57.759
<v Speaker 1>a bite. That could have other interpretations, but the seasoning

0:34:57.800 --> 0:35:01.319
<v Speaker 1>interpretation seems to be a pretty good one. Like why

0:35:01.320 --> 0:35:03.879
<v Speaker 1>else would they be dipping it again every time they

0:35:03.880 --> 0:35:07.760
<v Speaker 1>take a bite off off of the piece of food. Yeah,

0:35:07.800 --> 0:35:10.720
<v Speaker 1>you can see this as something that emerges out of purely,

0:35:11.239 --> 0:35:15.319
<v Speaker 1>you know, the washing behavior. But then they grow to realize. Yeah,

0:35:15.360 --> 0:35:18.400
<v Speaker 1>if the potato has been dipped in salt water, it

0:35:18.520 --> 0:35:21.520
<v Speaker 1>is more satisfying, and it of course is not only

0:35:21.920 --> 0:35:25.839
<v Speaker 1>enhancing taste it is it is also supplying something that

0:35:25.880 --> 0:35:29.000
<v Speaker 1>the monkey's body needs exactly. So I would say that

0:35:29.080 --> 0:35:33.000
<v Speaker 1>I think the seasoning interpretation of this behavior is not conclusive.

0:35:33.040 --> 0:35:35.360
<v Speaker 1>We don't know for sure that's what they're doing, but

0:35:35.600 --> 0:35:38.480
<v Speaker 1>it seems pretty valid, like it seems certainly on the table.

0:35:39.320 --> 0:35:41.520
<v Speaker 1>Of course, as we talked about before, a potato tastes

0:35:41.560 --> 0:35:43.680
<v Speaker 1>so much better with some seasoning. The same goes for

0:35:43.719 --> 0:35:46.680
<v Speaker 1>a sweet potato. So yeah, could it be that this

0:35:46.760 --> 0:35:50.160
<v Speaker 1>is not only an example of cultural transmission in non

0:35:50.280 --> 0:35:55.759
<v Speaker 1>human animals monkeys learning a non instinctual behavior from one

0:35:55.800 --> 0:35:59.000
<v Speaker 1>monkey to another within the troop, but also an example

0:35:59.080 --> 0:36:03.520
<v Speaker 1>of cookery ulture, cuisine emerging. Yeah, yeah, I think that's

0:36:03.520 --> 0:36:14.920
<v Speaker 1>a fascinating example. Now, in putting together these episodes, you

0:36:15.760 --> 0:36:18.200
<v Speaker 1>assembled a list of different things that were part of

0:36:18.520 --> 0:36:24.040
<v Speaker 1>human food culture culinary practices that we were using a

0:36:24.080 --> 0:36:29.560
<v Speaker 1>sort of a guide to try and look for behaviors

0:36:29.600 --> 0:36:32.759
<v Speaker 1>in the animal world that yeah, more or less line

0:36:32.800 --> 0:36:35.719
<v Speaker 1>up with them. Like, for instance, we talked about the

0:36:35.800 --> 0:36:39.520
<v Speaker 1>processing of food, the butchery practices of course, of the

0:36:39.560 --> 0:36:43.600
<v Speaker 1>butcher board, the shrike, the lambaguey er, you know, and

0:36:43.680 --> 0:36:46.080
<v Speaker 1>to a certain extent, you could make an argument that

0:36:46.200 --> 0:36:49.520
<v Speaker 1>any kind of predator that doesn't eat its prey hole

0:36:50.040 --> 0:36:53.160
<v Speaker 1>is engaging in some sort of butchery, right. It's if

0:36:53.160 --> 0:36:57.600
<v Speaker 1>it's selectively eating parts of the corpse of the cadaver,

0:36:58.960 --> 0:37:02.640
<v Speaker 1>then you could make it a week case for this. Yes, though,

0:37:02.840 --> 0:37:05.560
<v Speaker 1>when when I start thinking about human butchery, you know,

0:37:05.600 --> 0:37:07.640
<v Speaker 1>one thing my mind goes to is like the classic

0:37:07.680 --> 0:37:10.719
<v Speaker 1>butcher's tools, the tools you see next to the big

0:37:10.719 --> 0:37:13.759
<v Speaker 1>old wooden block that the animal would be taken apart in.

0:37:13.920 --> 0:37:16.000
<v Speaker 1>Of course you've got your knives, and that would be

0:37:16.040 --> 0:37:18.959
<v Speaker 1>related to, you know, the things we've already been talking about.

0:37:19.160 --> 0:37:21.239
<v Speaker 1>But another butcher tool you often see is that big

0:37:21.239 --> 0:37:25.799
<v Speaker 1>old hammer. What's that hammer for? For tenderizing the meat?

0:37:26.800 --> 0:37:30.279
<v Speaker 1>So for many of our tougher foods, the material must

0:37:30.320 --> 0:37:33.840
<v Speaker 1>be made tender prior to cooking and or consumption. The

0:37:34.000 --> 0:37:37.520
<v Speaker 1>tenderization of meat with a hammer or mallet or masher

0:37:37.960 --> 0:37:41.760
<v Speaker 1>is a great physical example of this, you know, and

0:37:42.080 --> 0:37:45.080
<v Speaker 1>you know it also essentially busts out some extra chewing

0:37:45.160 --> 0:37:47.640
<v Speaker 1>prior to cooking. You know, you don't want to spend

0:37:48.520 --> 0:37:51.320
<v Speaker 1>x amount of extra time chewing that meat, or in

0:37:51.320 --> 0:37:53.760
<v Speaker 1>any cases, like chewing that potato or whatever it happens

0:37:53.800 --> 0:37:56.600
<v Speaker 1>to be. Let's break it down a bit physically before

0:37:56.960 --> 0:38:00.000
<v Speaker 1>it goes into our mouth. But of course we don't

0:38:00.120 --> 0:38:04.839
<v Speaker 1>just tenderize foods with hammers and mallets. We also tenderize

0:38:04.880 --> 0:38:09.160
<v Speaker 1>them chemically via special enzymes as well as via mixtures

0:38:09.200 --> 0:38:12.399
<v Speaker 1>like vinegar and broth. And when we apply a marinade,

0:38:12.600 --> 0:38:15.359
<v Speaker 1>we're not only flavoring the matter we intend to cook

0:38:15.960 --> 0:38:20.200
<v Speaker 1>and or eat, but also we're softening it up. And again,

0:38:20.320 --> 0:38:23.680
<v Speaker 1>this is a chemical breakdown that occurs inside the body

0:38:23.680 --> 0:38:26.960
<v Speaker 1>as well, beginning in the mouth. Now, we've discussed some

0:38:27.040 --> 0:38:31.520
<v Speaker 1>methods of externalizing this process before, and they bear at

0:38:31.600 --> 0:38:36.040
<v Speaker 1>least equipment mentioned here. Houseflies consume their food is a

0:38:36.080 --> 0:38:41.040
<v Speaker 1>liquid diet. So first a housefly scrubs food that it

0:38:41.320 --> 0:38:45.560
<v Speaker 1>finds with bristles on the end of its proboscis, freeing

0:38:45.640 --> 0:38:49.000
<v Speaker 1>up food particles. So think of these like dusty food

0:38:49.040 --> 0:38:53.080
<v Speaker 1>particles that the housefly has found, and then it vomits

0:38:53.160 --> 0:38:56.960
<v Speaker 1>up a slurry of saliva and digestive juices, and in

0:38:57.080 --> 0:38:59.480
<v Speaker 1>doing this It's kind of like adding hot water to

0:39:00.000 --> 0:39:03.879
<v Speaker 1>an oatmeal mix, you know. So if you're being very

0:39:03.880 --> 0:39:05.880
<v Speaker 1>generous with the term, you could say a housefly is

0:39:05.920 --> 0:39:10.160
<v Speaker 1>cooking sort of, and then of course it slurps all

0:39:10.200 --> 0:39:12.520
<v Speaker 1>of it up. I love that. Yeah, So it's it's

0:39:12.560 --> 0:39:17.160
<v Speaker 1>cooking right from its own gut. Yeah. Spiders are also

0:39:17.160 --> 0:39:19.839
<v Speaker 1>ane of the great example. They'll inject digestive juices into

0:39:19.880 --> 0:39:22.880
<v Speaker 1>the bodies of their prey to break down the insides,

0:39:22.960 --> 0:39:27.200
<v Speaker 1>you know, particularly prey that's been paralyzed or wrapped up

0:39:27.200 --> 0:39:31.439
<v Speaker 1>in webbing. And then after this these juices have had

0:39:31.480 --> 0:39:34.839
<v Speaker 1>time to work, they can simply drink the insides of

0:39:34.880 --> 0:39:36.759
<v Speaker 1>the prey that they have captured. I believe we did

0:39:36.760 --> 0:39:39.719
<v Speaker 1>a whole episode on what this would be like, What

0:39:39.840 --> 0:39:41.920
<v Speaker 1>would it would be like to be eaten by a spider?

0:39:42.239 --> 0:39:46.000
<v Speaker 1>It was called I Was Eaten by a Giant spider. Yeah,

0:39:46.040 --> 0:39:48.359
<v Speaker 1>that was a fun one. Yeah. Yeah. Now, it's also

0:39:48.400 --> 0:39:51.800
<v Speaker 1>worth noting that these various means of tenderizing organic material,

0:39:52.239 --> 0:39:56.200
<v Speaker 1>you know, it's it's also comparable to the process of decomposition,

0:39:56.719 --> 0:40:00.800
<v Speaker 1>So we might well loop in natural decomposition into this category,

0:40:00.880 --> 0:40:04.600
<v Speaker 1>especially for scavenger creatures who take advantage of such conditions.

0:40:04.840 --> 0:40:07.759
<v Speaker 1>They can take advantage of food material that has been

0:40:07.800 --> 0:40:13.200
<v Speaker 1>softened by decomposition, and they have evolved to tolerate levels

0:40:13.200 --> 0:40:16.640
<v Speaker 1>of decomposition that other animals would not be able to handle.

0:40:17.000 --> 0:40:21.200
<v Speaker 1>Now that that brings up another question, how about fermentation?

0:40:21.239 --> 0:40:23.280
<v Speaker 1>That was another one we had on the list. Are

0:40:23.440 --> 0:40:25.120
<v Speaker 1>you know there are plenty of examples of animals that

0:40:25.200 --> 0:40:28.840
<v Speaker 1>consume fermenting fruit, for example, but are there examples of

0:40:28.880 --> 0:40:32.000
<v Speaker 1>animals that are more actively involved in the fermentation process.

0:40:32.680 --> 0:40:36.759
<v Speaker 1>I couldn't really find any good examples, but again we

0:40:36.800 --> 0:40:41.040
<v Speaker 1>could roughly file fermentation under the category of decomposition. So

0:40:41.080 --> 0:40:44.000
<v Speaker 1>animals like elephants, birds and monkeys that eat fermented fruit

0:40:44.320 --> 0:40:47.960
<v Speaker 1>are also taking advantage of this process. And on that note,

0:40:48.040 --> 0:40:50.240
<v Speaker 1>I'd like to touch on just a few examples of

0:40:50.280 --> 0:40:53.680
<v Speaker 1>animals that get involved with a couple of other activities

0:40:53.719 --> 0:40:57.400
<v Speaker 1>that are that are highly important to human food culture,

0:40:58.239 --> 0:41:02.480
<v Speaker 1>the storing of food, but then all of agriculture itself.

0:41:03.000 --> 0:41:06.000
<v Speaker 1>So first on the the just on the topic of

0:41:06.000 --> 0:41:10.040
<v Speaker 1>of hoarding food, of creating a cash of food that

0:41:10.120 --> 0:41:14.560
<v Speaker 1>one can can turn to, especially during the winter. There

0:41:14.560 --> 0:41:16.719
<v Speaker 1>are numerous examples of this and we could easily talk

0:41:16.719 --> 0:41:20.719
<v Speaker 1>about chipmunks and squirrels and whatnot. But I wanted to

0:41:20.760 --> 0:41:24.320
<v Speaker 1>talk just a little bit about a superpredator of note

0:41:24.880 --> 0:41:29.640
<v Speaker 1>um and that is the mole. Superspredator mole. Yeah, I mean,

0:41:29.680 --> 0:41:32.960
<v Speaker 1>if you're if you're an earthworm, the mole is the

0:41:32.960 --> 0:41:36.400
<v Speaker 1>the ultimate destroyer. It is the superpredator of the earthworm world.

0:41:37.239 --> 0:41:40.719
<v Speaker 1>It eats nearly its weight in worms and similar subterranean

0:41:40.760 --> 0:41:45.160
<v Speaker 1>creatures every day. Uh and uh, it's it's impressive, but

0:41:45.200 --> 0:41:47.680
<v Speaker 1>of course this is standard hunt and eat behavior, right,

0:41:47.719 --> 0:41:51.200
<v Speaker 1>nobody's going to accuse the mole of engaging in uh,

0:41:51.320 --> 0:41:54.600
<v Speaker 1>you know, culinary activities here by gobbling it's it's weight

0:41:54.920 --> 0:41:58.040
<v Speaker 1>in earthworms every day. But where it begins to mirror

0:41:58.160 --> 0:42:00.439
<v Speaker 1>some aspects of human food culture is that, like many

0:42:00.440 --> 0:42:05.640
<v Speaker 1>other animals, moles also stockpile food for leaner times. While

0:42:05.719 --> 0:42:10.080
<v Speaker 1>various rodents famously stockpile nuts and human stockpile all sorts

0:42:10.080 --> 0:42:14.319
<v Speaker 1>of foods, the mole creates a horrifying subterranean dungeon of

0:42:14.400 --> 0:42:18.280
<v Speaker 1>living worms. And this is an example of larger hoarding.

0:42:18.680 --> 0:42:23.239
<v Speaker 1>Whoa living worms, yeah, or in some cases you might

0:42:23.280 --> 0:42:27.040
<v Speaker 1>say sort of half living worms. I guess it creates

0:42:27.040 --> 0:42:30.879
<v Speaker 1>a limbo of worms. A limbo of worms. Yeah. So

0:42:30.920 --> 0:42:33.720
<v Speaker 1>I was reading about this in a Tree Hugger article

0:42:33.960 --> 0:42:38.400
<v Speaker 1>by Russell McClendon citing a Mammal Society a Species Overview article,

0:42:38.840 --> 0:42:41.600
<v Speaker 1>and it points out that the moles have a worm

0:42:41.719 --> 0:42:44.920
<v Speaker 1>paralyzing toxin in their bite, but they also will just

0:42:44.960 --> 0:42:49.160
<v Speaker 1>bite the heads of an earthworm to ensure a debilitating

0:42:49.320 --> 0:42:53.759
<v Speaker 1>but non fatal injury to said worm. And then you know,

0:42:53.760 --> 0:42:56.000
<v Speaker 1>they'll eat a lot of worms obviously, but then they'll

0:42:56.040 --> 0:43:00.839
<v Speaker 1>start dragging them away and they'll create these chambers full

0:43:00.880 --> 0:43:05.680
<v Speaker 1>of still living worms that they can munch on through

0:43:05.719 --> 0:43:09.600
<v Speaker 1>the leaner months. Single mole chambers have been found to

0:43:09.600 --> 0:43:13.560
<v Speaker 1>contain as many as four hundred and seventy live earthworms,

0:43:13.719 --> 0:43:16.399
<v Speaker 1>So that's about eight hundred and twenty grams or one

0:43:16.440 --> 0:43:21.360
<v Speaker 1>point eight pounds of still living, still writhing earthworms for

0:43:21.400 --> 0:43:23.840
<v Speaker 1>them to eat. Wow. This one, like I said, I

0:43:23.840 --> 0:43:27.239
<v Speaker 1>feel like it's a more grizzly and alarming example of

0:43:27.280 --> 0:43:29.319
<v Speaker 1>the sort of thing we're used to. You know, it's like, oh, yeah,

0:43:29.320 --> 0:43:31.120
<v Speaker 1>it's the storing nuts for the winter. Now this is

0:43:31.120 --> 0:43:34.560
<v Speaker 1>storing live earthworms and a big dungeon for the winter.

0:43:35.120 --> 0:43:37.439
<v Speaker 1>Now we would be remiss if we didn't at least

0:43:37.480 --> 0:43:40.160
<v Speaker 1>touch on a topic that, of course I think we've

0:43:40.239 --> 0:43:44.000
<v Speaker 1>we've discussed in greater length before in the past. But

0:43:44.840 --> 0:43:49.680
<v Speaker 1>bee honey. You know, this is the sweet food stuff

0:43:49.719 --> 0:43:51.520
<v Speaker 1>produced by the honey bee as well as some other

0:43:51.560 --> 0:43:55.640
<v Speaker 1>bee species, and honey is basically yes bee vomit. We

0:43:55.719 --> 0:43:59.480
<v Speaker 1>have enzyme activity playing a role in this, as well

0:43:59.520 --> 0:44:05.080
<v Speaker 1>as water evaporation transforming mere sugary organic secretions of usually

0:44:05.120 --> 0:44:09.160
<v Speaker 1>plants into an ideal storable food. So in this example

0:44:09.200 --> 0:44:14.759
<v Speaker 1>we see both food production and storage. So it's one

0:44:14.760 --> 0:44:18.120
<v Speaker 1>we're all familiar with. We all know where honey comes from.

0:44:18.160 --> 0:44:20.400
<v Speaker 1>We know the miracle of honey. It's one of the

0:44:20.480 --> 0:44:24.760
<v Speaker 1>great achievements of the animal world, certainly the insect world.

0:44:24.880 --> 0:44:27.399
<v Speaker 1>But it's also when we're so familiar with we kind

0:44:27.400 --> 0:44:30.160
<v Speaker 1>of it's easy to forget the wonder of it, to

0:44:30.200 --> 0:44:33.239
<v Speaker 1>overlook the wonder of what is being achieved here. And

0:44:33.280 --> 0:44:37.080
<v Speaker 1>then another prime example from the insect world concerns the

0:44:37.120 --> 0:44:39.480
<v Speaker 1>marvel of the leaf cutter ants, of which there are

0:44:39.520 --> 0:44:43.680
<v Speaker 1>around I think forty seven identified species. They cultivate their

0:44:43.719 --> 0:44:47.520
<v Speaker 1>own crop of fungus, growing it on harvested leaf clippings.

0:44:47.719 --> 0:44:51.520
<v Speaker 1>In some cases, these fungus species are entirely dependent on

0:44:51.560 --> 0:44:55.080
<v Speaker 1>their ant masters. You know, we're talking like extinct in

0:44:55.120 --> 0:44:58.960
<v Speaker 1>the wild situations, but it is I mean, these are

0:44:59.640 --> 0:45:04.160
<v Speaker 1>these are and complex societies of these leaf cutter ants.

0:45:04.200 --> 0:45:07.800
<v Speaker 1>But what they are practicing here is agriculture in a nutshell,

0:45:07.840 --> 0:45:10.439
<v Speaker 1>and they've been practicing it for a period of time

0:45:10.480 --> 0:45:14.520
<v Speaker 1>that dwarfs human agricultural practice. They got a stew going

0:45:14.840 --> 0:45:16.879
<v Speaker 1>they do. Yeah, So, I mean, I think it's neat

0:45:16.880 --> 0:45:19.360
<v Speaker 1>to kind of look at some of those examples, especially

0:45:19.400 --> 0:45:23.920
<v Speaker 1>because they kind of forecast what humans would come to do.

0:45:24.040 --> 0:45:26.800
<v Speaker 1>Like what humans are doing with their food is certainly

0:45:26.840 --> 0:45:30.400
<v Speaker 1>an advanced model compared to anything going on in the

0:45:30.480 --> 0:45:34.320
<v Speaker 1>human world. But it's not unconnected. It's it's not an island.

0:45:34.680 --> 0:45:39.520
<v Speaker 1>You know, you see shadows of what we are doing

0:45:40.200 --> 0:45:44.680
<v Speaker 1>in these other practices, in these other approaches to life,

0:45:45.200 --> 0:45:47.279
<v Speaker 1>and so yeah, what we're doing is just kind of

0:45:47.280 --> 0:45:51.719
<v Speaker 1>the the human complication of that. All right, we're gonna

0:45:51.719 --> 0:45:54.880
<v Speaker 1>go and close out this episode, but you know, we

0:45:54.960 --> 0:45:57.200
<v Speaker 1>would love to come back in the future and discuss

0:45:57.760 --> 0:46:01.359
<v Speaker 1>the cuisine of non animals a bit more so if

0:46:01.440 --> 0:46:04.919
<v Speaker 1>you have particular favorite examples of this, or if there's

0:46:04.960 --> 0:46:06.680
<v Speaker 1>something in the animal world that you would like to

0:46:06.719 --> 0:46:09.839
<v Speaker 1>personally make a case for, or is just something you've

0:46:09.840 --> 0:46:12.600
<v Speaker 1>observed right in and let us know, we'd love to

0:46:12.600 --> 0:46:15.040
<v Speaker 1>hear from you. And you know, we were just chatting

0:46:15.120 --> 0:46:16.880
<v Speaker 1>a few minutes ago off Mike that you know, there

0:46:16.880 --> 0:46:19.600
<v Speaker 1>are a number of different leads for this episode that

0:46:19.680 --> 0:46:22.040
