Questions
Why do zebras have stripes? (00:34)
Our guess
Heat regulation, or confusing predators when the herd runs together.
Heat regulation, or confusing predators when the herd runs together.

The answer
Unsettled. A newer UCLA study suggests the black stripes help zebras stay cool in the midday heat, while the long-standing consensus is camouflage or confusing predators, with little direct evidence. A group of zebras is called a zeal or a dazzle.

[00:00] We do under Googles. That was the play of super excited told us we had to [00:14] We signed up for it [00:18] In the end it's gonna be better and more true than Google can give you all right [00:23] The question is where did Coalson put his under Google? [00:34] What does it happen its pockets [00:40] These are this is one of the ones that [00:42] You know I think about all the time, and I think [00:45] My really smart friends probably know and I maybe should be too embarrassed to ask it, but instead of googling [00:52] And I'm gonna ask you guys [00:55] Why does zebras have stripes [00:59] Hmm cuz that's the way God made them yeah next question [01:05] I [01:06] Know I mean I feel like so so my theory is [01:12] that [01:13] It's this sort of like [01:16] cooling system [01:18] Right okay, so like the black absorbs the heat and the white reflects the Sun [01:25] And it's like this absorbing reflecting [01:30] Some kind of biological coil system that yes, yes [01:34] And so and so that it's really effective [01:38] For the heat of the zebra that's my theory, so you think in the summertime it like sells [01:44] It sells the energy back to the grid or something [01:50] Yeah [01:52] Yeah in those winters in the savannah [01:55] Which is notoriously cold it can stay warm in the winter and then right cool, and so it's like heat pump [02:02] Yeah, or like you know a hump on a camel's back. Just to just holds the [02:07] Water water holds the water holds the heat [02:12] Holds the cool [02:14] Okay [02:15] And releases it when necessary [02:20] Okay, I'm gonna I feel like [02:25] Probably not right [02:27] Evolutionarily that's probably perfect. We should all probably be zebra striped. Yeah, I think that so [02:33] Zebras are already mammals, so they have pretty good heat regulation. I think okay in distribution their [02:41] Homeothermic and [02:43] So my understanding always from when I was a kid [02:47] So I've never done any further reading on this was that it was a it was a defense mechanism [02:53] so that when the zebras ran as a herd the stripes would like [03:00] Basically make it hard to pick a single zebra out of the pack and [03:05] Thus making it harder for lions or whatever predators to hunt them [03:11] That's what I that's where I that's where I fall so like it's big. It's like visually [03:18] disturbing [03:19] When a pack of zebras or what's a what's a group of zebras called? That's a good question [03:25] I don't know what the collective term is, but I'm sure it's awesome. I [03:29] Want to hear what you think it is cuz you're full of ideas. I think it's a murder of zebras [03:34] I think it's a murder of zebras. Okay. Yeah, yeah, don't exactly know [03:38] I did spend a long time on the Wikipedia page for collective nouns or a [03:43] maybe a [03:45] clusterfuck of zebras [03:47] Is that I? [03:50] Think that's a scientific definitely got my vote [03:54] But no, I like that idea so it's just like the [03:59] The line can't see there's just too many lines [04:01] It's just like a full-blown hypnosis like the spinning wheel and you're the card. Yes. Yeah, I like that. Yeah [04:09] Makes them dizzy. I [04:12] Still haven't gotten over the weird [04:14] Why rabbits have white tails thing which is apparently has something to do with the chase and stuff on the end [04:21] We're pretty some to Google. So I'll stick with some sort of [04:25] biological camouflage [04:29] I won't rule out that it has alternate [04:32] alternative uses though such as [04:34] weird heat exchange [04:37] What about what about like the peacock thing? Like it's just showing off to its [04:42] You know mate mate with the least colorful colors it could come up with. Yeah [04:50] Well, they're they're very boring species [04:54] So it's so you're actually trying to be more boring it's yes, yes [04:59] Sure nerds are really valued in a zebra cluster. Fuck. That's right [05:06] You're going for a sort of like the you know state the homebody sort of you know stay at home [05:13] You know do the crossword puzzle read a book type. I'm not gonna I'm not gonna be out at the club [05:19] right now [05:21] right zebra move I [05:23] wonder if the stripes on a [05:26] Zebra are in any way related to say the spots on a [05:30] Cow or something like that. Okay, and what is have a similar cow thing like it? Well, you can imagine that cows and herds [05:38] Like I see you got your standard dairy cow, right has the splotches and stuff [05:43] then maybe in a herd [05:46] Those similarly act as camouflage, but it's more of like a psychedelic like they they came around in the 60s or something [05:53] So the cows came around the 60s. Yeah, whereas the zebras are much more old school. It's more like straight up and down [06:00] Okay, it's sort of a design thing. Yes. Yeah. Yeah [06:05] So the you think that the zebras are like some sort of pre postmodern stuff, right? Exactly [06:13] Potential okay, what about skin disease? I'm against it [06:23] What what about it? I don't know. I'm just throwing out ideas [06:32] Wait, what how does that relate to the stripe? Do you think it's like it helps you not get skin disease or something? [06:37] Well, no, I was thinking like maybe they're all just really black horses with skin disease. Oh [06:41] You think it may be skin disease? Yeah. Yeah. Yeah, I'm gonna I'm gonna vote against that one. Okay [06:48] I don't think the entire species has skin disease or you unless you think [06:53] Genetic thing, you know, like it's just cast down [06:59] Mmm. Mmm update a group of zebras is has two alternative names. It's called a zeal. Ooh [07:09] or a dazzle [07:14] Yeah, I'd like zeal better but do you both are fantastic zebra zeal [07:26] dazzles zebra [07:27] Yeah, so do we have a [07:33] an actual answer for the [07:37] The purpose of the stripes, holy shit, I [07:43] Think Coalson might be it's not really about heating and cooling is it? Oh my god [07:51] Well a new study suggests that [07:54] The black stripes may have evolved to help these iconic creatures stay cool [07:58] in the midday African heat [08:01] Wait, I I keep up on my new studies [08:05] Mmm, wouldn't it be the opposite of that? [08:10] I'm [08:11] Curious as to why you know, if it's supposed to help with the heat why other species why everybody isn't like that [08:19] Well, I I will say that that's not the best evidence that okay, that's why [08:25] The correlation is not causation. We was the author on that [08:29] Was it? [08:32] It was UCLA and it was published in the Journal of Royal Society open science [08:38] But that that that it seems like it's still in its infancy that particular [08:44] Yeah, a lot of reasoning. I [08:46] Don't like that. That's what Google recommends. Mm-hmm. I [08:50] Guess it's the latest study though. Oh, it's the it's the latest and greatest so therefore it must be right, right [08:58] well, it seems like the the [09:02] Dogma or the consensus in the field is that [09:05] It's a camouflage sort of kind [09:12] Yeah, but they there's no real evidence for that. It's sort of just a guess [09:17] It is not settled science, but we do know that a group of zero zebras is a dazzle [09:23] that dazzle me once [09:26] shame on you [09:28] You guys want to talk about the other under Google that was sent in to us this week [09:36] No, I'm sure you could ask those one more. This one came in from Andrew Preston [09:44] listener of the show [09:46] This is your podcast intro is comprised of a variety of different audio collections [09:51] Some seemingly from the show others from historic radio calls Roy Hibert, etc. I [09:58] Think I noticed a new clip or two attitude as well [10:00] I think can you guys name or remember where all the different clips are from? [10:06] Why or how did you come up with these clips as your intro Coalson? I think this is your your territory with [10:13] You are the the jingle master [10:16] Sure. So the idea was to [10:22] Create a an opening jingle that was about that was preparatory. I suppose [10:29] So I think there's a loop of you saying [10:34] What do you say? [10:37] This is a great question [10:44] Just [10:46] Just prepare for yes. Yes. Yeah. Yeah [10:50] and so [10:52] The clips that we used. Yes, we use the Roy Hibert clip in the the playoffs where he's like you guys don't listen to us [10:58] anyway [10:59] Any curses which I thought was hysterical [11:02] and [11:04] But that was sort of felt true for our podcast as well [11:08] And and then boom baby because that's classic [11:12] And then the rest of it was I've got Jason doing one of my favorite things that's ever happened on the pie [11:19] Which is the Evan Turner impression? [11:22] And it's [11:24] Yeah, be me. Well, yeah meatwad slash Evan Turner and it's get his shoes on [11:29] And he's getting ready for a show. I like that [11:32] And I think Harper says it's gonna be great. It's gonna be perfect, which is just you know, just a nice moment and then [11:39] and then [11:42] The end of the show we had [11:44] Previously a whole bit which was one of my favorite bits we ever did and we talked about Roy Hibert having an inflatable bed [11:51] on the road and it turned into a big bit about [11:55] Bouncy castles and all this stuff and then [12:00] about how we would inflate a bouncy castle every time Ray Hibert went into a hotel room and [12:06] And the bit was who doesn't love bouncy castles and and Joey says Hitler [12:11] Which is great because that's who hates who's evil and hates everything [12:16] But what I realized is that the whole show ended on Joey saying Hitler [12:20] And so the whole week the whole jingle and hear me talk every week [12:25] Yeah, and so I went back and added some more preparatory things [12:31] Another favorite line which was from an under Google or under Google Bowl Harper [12:38] Saying that you couldn't jump through Neptune and be okay, which I think it's just it's probably the most true thing [12:45] That's ever been set on the pod. So I felt like that needed to be added in [12:50] And then and then a bit where Jason and I were were planning for a [12:57] The rainbow connection and I started talking about [13:00] bears and chickens and stuff and [13:03] That felt also preparatory [13:05] So the whole idea is that I took clips from the show that were funny [13:09] But also sort of leading towards something and building towards something [13:14] while Joey's saying is [13:16] just prepare for [13:18] Undebeatable goodness, and that's how it ends and then with the drum and we and then shout out to [13:25] Scoot dubs who allowed us to use that [13:31] Jingle [13:32] the background and [13:34] Just yeah, I appreciate the Andrew Preston appreciate you asking [13:38] But yeah, the whole idea was to to prep you for the insanity that's coming
