Introduction, hurricanes and earthquakes

Voice-over: You're listening to the Skeptics' Guide to the Universe, your escape to reality. [00:08.920 --> 00:12.760] Hello and welcome to the Skeptic's Guide to the Universe.

[00:12.760 --> 00:17.440] Today is Thursday, October 6th, 2022, and this is your host, Steve Novella.

[00:17.440 --> 00:19.200] Joining me this week are Bob Novella,

[00:19.200 --> 00:20.200] Hey everybody.

[00:20.200 --> 00:21.200] Kara Santamaria,

[00:21.200 --> 00:22.200] Howdy.

[00:22.200 --> 00:23.200] Jay Novella,

[00:23.200 --> 00:24.200] Hey guys.

[00:24.200 --> 00:25.200] And Evan Bernstein.

[00:25.200 --> 00:27.080] Good evening folks.

[00:27.080 --> 00:33.280] So 900, 900, 900, 900, wait, what?

[00:33.280 --> 00:35.600] This is SGU episode 900, nine zero zero.

[00:35.600 --> 00:36.600] How did that happen?

[00:36.600 --> 00:39.120] I know, it kind of snuck up on you.

[00:39.120 --> 00:40.120] After 899, you know.

[00:40.120 --> 00:41.120] Who would have thought of that?

[00:41.120 --> 00:46.020] Yeah, we're not going to make a big deal out of it.

[00:46.020 --> 00:50.000] But what this means is that we're just a little bit over two years away from 1000.

[00:50.000 --> 00:53.160] I think we're going to have to do something big.

[00:53.160 --> 00:54.160] Something big.

[00:54.160 --> 00:55.720] It's going to have to be something big.

[00:55.720 --> 00:57.400] Like record naked or something.

[00:57.400 --> 01:01.360] Yeah, like can it be, can it be something big, but also something that's not exhausting?

[01:01.360 --> 01:03.560] I don't know, Kara, that's a big ask.

[01:03.560 --> 01:04.560] Can we find that, pal?

[01:04.560 --> 01:05.560] Like a 48-hour episode?

[01:05.560 --> 01:06.560] No!

[01:06.560 --> 01:12.200] We will come up with something to do for 1000, but.

[01:12.200 --> 01:13.200] What about a destination?

[01:13.200 --> 01:14.200] Can we make it?

[01:14.200 --> 01:15.200] Ooh.

[01:15.200 --> 01:16.200] I like that.

[01:16.200 --> 01:17.200] Going somewhere?

[01:17.200 --> 01:18.200] Me too.

[01:18.200 --> 01:19.200] Disney World?

[01:19.200 --> 01:20.200] No, think bigger, Bob.

[01:20.200 --> 01:21.200] Yeah, right?

[01:21.200 --> 01:22.200] Yeah.

[01:22.200 --> 01:23.200] Okay.

[01:23.200 --> 01:24.200] Disney World during Halloween.

[01:24.200 --> 01:29.280] Two years, two years to plan.

[01:29.280 --> 01:30.520] We're open to suggestions.

[01:30.520 --> 01:31.520] Two years.

[01:31.520 --> 01:32.520] Yeah, we can 20.

[01:32.520 --> 01:37.840] It should be around the, ooh, Labor Day of 2024, right?

[01:37.840 --> 01:38.840] You'll be 2024.

[01:38.840 --> 01:39.840] Late 2024.

[01:39.840 --> 01:40.840] Yeah.

[01:40.840 --> 01:43.880] Kara, how did you survive your hurricane?

[01:43.880 --> 01:44.880] I survived.

[01:44.880 --> 01:50.400] It was kind of weird because before it actually made landfall, I'm trying to remember.

[01:50.400 --> 01:52.340] So Hurricane Ian, it was Tropical Storm Ian.

[01:52.340 --> 01:57.260] It was apparently, did you guys see this, two miles per hour shy of being a category

[01:57.260 --> 01:58.260] five.

[01:58.260 --> 01:59.260] Yes.

[01:59.260 --> 02:03.280] Like it didn't quite, it was literally like within a couple of miles of making the cutoff.

[02:03.280 --> 02:05.540] So it was still technically a category four.

[02:05.540 --> 02:10.760] But before it even made landfall, I would say about two days before it made landfall,

[02:10.760 --> 02:15.280] we had all of the storms that were spinning off of it hit where I am in South Florida

[02:15.280 --> 02:16.600] in Fort Lauderdale.

[02:16.600 --> 02:20.680] So two tornadoes touched down within a couple miles of me.

[02:20.680 --> 02:26.320] All night there were these like tornado warnings going off on my phone and just like a lot

[02:26.320 --> 02:27.740] of like severe weather warnings.

[02:27.740 --> 02:28.740] And they're so funny.

[02:28.740 --> 02:32.280] They're like, seek shelter in basement immediately, which is like, nobody in Florida has a basement.

[02:32.280 --> 02:34.320] Like why would you put that warning there?

[02:34.320 --> 02:35.320] Right?

[02:35.320 --> 02:36.320] Well, they got to say it.

[02:36.320 --> 02:37.320] Yeah.

[02:37.320 --> 02:38.320] Exactly.

[02:38.320 --> 02:42.440] And then our clinic was closed the next day.

[02:42.440 --> 02:45.280] I mean, they waited way too long to close it, but they did ultimately close it the

[02:45.280 --> 02:46.680] next day.

[02:46.680 --> 02:48.600] But the weather was just windy.

[02:48.600 --> 02:49.880] Nothing really happened here.

[02:49.880 --> 02:51.040] It didn't really even rain.

[02:51.040 --> 02:53.680] And then the day that it made landfall, I think it was either later that day or early

[02:53.680 --> 02:59.480] the next morning that it made landfall, it just devastated Fort Myers on the West Coast

[02:59.480 --> 03:00.480] and just pummeled.

[03:00.480 --> 03:01.760] Like people, a lot of people died.

[03:01.760 --> 03:03.200] Like it was terrible.

[03:03.200 --> 03:06.960] So much property damage, but we didn't see any of it where I am.

[03:06.960 --> 03:08.520] And that's the thing about hurricanes.

[03:08.520 --> 03:10.600] They're just, they're predictable.

[03:10.600 --> 03:15.160] They're more predictable than tornadoes, but they can just turn on a dime and they can

[03:15.160 --> 03:16.160] pick up speed.

[03:16.160 --> 03:17.500] They can drop speed.

[03:17.500 --> 03:21.880] The forecasts are amazing, but they also have a mind of their own.

[03:21.880 --> 03:26.040] And then I had this whole travel saga where I was going back to LA that weekend and it

[03:26.040 --> 03:28.560] was not even related to the hurricane, which was extra obnoxious.

[03:28.560 --> 03:31.480] It was related to emergency lights on the floor of the plane.

[03:31.480 --> 03:32.480] Kill me.

[03:32.480 --> 03:33.480] I was delayed 14 hours.

[03:33.480 --> 03:38.880] But I was following, yeah, it was bad, but I was following the news and this was amazing.

[03:38.880 --> 03:45.200] So as Ian made landfall, it like did all this destruction and damage because it was a super

[03:45.200 --> 03:46.200] powerful storm.

[03:46.200 --> 03:50.160] And then of course it starts to lose energy and it was downgraded to a tropical storm

[03:50.160 --> 03:54.180] as it moved inland and like dumped a bunch of water on a bunch of inland cities.

[03:54.180 --> 03:59.300] After it crossed over Florida and hit water again, it picked back up and became a category

[03:59.300 --> 04:03.960] one or two, maybe just a one, but it was recategorized as a hurricane again.

[04:03.960 --> 04:05.440] It was that powerful.

[04:05.440 --> 04:06.440] That's like nuts.

[04:06.440 --> 04:07.440] It refueled itself.

[04:07.440 --> 04:08.440] Yeah.

[04:08.440 --> 04:09.440] It was kind of warm water.

[04:09.440 --> 04:10.440] Yeah.

[04:10.440 --> 04:13.040] Like that's, that's, that's a pretty intense storm.

[04:13.040 --> 04:17.160] I mean, this is like, was the worst one that hit Florida in decades, right?

[04:17.160 --> 04:21.840] I think, well, what I read was that it was the worst since 2018, which to me doesn't

[04:21.840 --> 04:23.680] seem like it was that long ago.

[04:23.680 --> 04:28.000] But I think they were saying it could have been, or it was almost like the fifth worst

[04:28.000 --> 04:30.300] storm in America.

[04:30.300 --> 04:32.880] Like there were, it was back when they were doing all the forecasts, they were like, this

[04:32.880 --> 04:34.040] is gearing up to be X.

[04:34.040 --> 04:39.560] And so I haven't seen the final takeaway of like, you know, the ranking system of like

[04:39.560 --> 04:41.880] worst storms to hit Florida, worst storms to hit America.

[04:41.880 --> 04:47.560] Of course, most of the terrible storms to hit America hit Florida, but also Puerto Rico,

[04:47.560 --> 04:51.640] also Texas, and some nor'easters in the Northeast.

[04:51.640 --> 04:54.540] But Florida gets pummeled by hurricanes all the time.

[04:54.540 --> 04:56.440] And you should have seen the people I work with down here.

[04:56.440 --> 04:58.480] Like I was like, uh, are we going to be okay?

[04:58.480 --> 04:59.480] And they're like, this is nothing.

[04:59.480 --> 05:00.480] You'll be fine.

[05:00.480 --> 05:01.480] They're like so.

[05:01.480 --> 05:02.480] They're like, whatever.

[05:02.480 --> 05:05.040] They probably won't even cancel school.

[05:05.040 --> 05:06.040] And they almost didn't.

[05:06.040 --> 05:08.580] I was like, what is happening?

[05:08.580 --> 05:11.600] Is that like earthquake culture in California similar?

[05:11.600 --> 05:13.080] Well, just get used to it.

[05:13.080 --> 05:17.260] And they're so used to everybody freaking out and then it like not hitting them.

[05:17.260 --> 05:19.720] But the sad thing is it probably does hit somewhere.

[05:19.720 --> 05:23.200] And so people who have actually lived through the devastation, like the people in Fort Myers

[05:23.200 --> 05:26.560] who lost everything, I don't think they have that casual view.

[05:26.560 --> 05:30.800] It's the people who have been so lucky that they've like just dodged a lot of bullets.

[05:30.800 --> 05:31.800] But I don't know.

[05:31.800 --> 05:32.800] I have the same thing with tornadoes.

[05:32.800 --> 05:36.040] Like my mom was texting me like, get in the bathtub, grab kitler, get in the bathtub.

[05:36.040 --> 05:38.440] I was like, mom, how many tornadoes warnings have we lived through?

[05:38.440 --> 05:40.920] I never got in the bathtub when we were little.

[05:40.920 --> 05:41.920] What are you doing?

[05:41.920 --> 05:42.920] Get in the bathtub.

[05:42.920 --> 05:43.920] I know.

[05:43.920 --> 05:44.920] It just sounds so ridiculous.

[05:44.920 --> 05:45.920] I know.

[05:45.920 --> 05:46.920] She's like, are you safe?

[05:46.920 --> 05:47.920] And I'm like, I don't know.

[05:47.920 --> 05:48.920] I'm in my apartment.

[05:48.920 --> 05:49.920] She's like, can you get to a lower level?

[05:49.920 --> 05:50.920] I'm like, what?

[05:50.920 --> 05:51.920] Go to somebody else's apartment?

[05:51.920 --> 05:52.920] Like, no.

[05:52.920 --> 05:57.080] So you have to get into the bathtub, but you also have to bring your mattress with you

[05:57.080 --> 05:59.040] and cover yourself with your mattress.

[05:59.040 --> 06:02.360] Which is like the funniest thing because I don't know about you, but I can't lift my

[06:02.360 --> 06:03.360] mattress.

[06:03.360 --> 06:04.360] Right.

[06:04.360 --> 06:05.360] It's so...

[06:05.360 --> 06:06.360] It's not very practical for everyone.

[06:06.360 --> 06:07.360] It's putting your backpack.

[06:07.360 --> 06:08.360] Right.

[06:08.360 --> 06:14.440] I mean, you have all these people like suffocating under their mattresses.

[06:14.440 --> 06:16.000] That was not the intention.

[06:16.000 --> 06:17.480] Oh, my God.

[06:17.480 --> 06:18.480] Jeez.

What's the Word? (6:20)

• Hominid vs Hominin

[06:18.480 --> 06:22.200] All right, Carrie, you're going to start us off with a what's the word?

[06:22.200 --> 06:23.200] What is the word?

[06:23.200 --> 06:26.680] Well, this week I figured we would do a bit of a refresher and I actually don't remember

[06:26.680 --> 06:30.200] because I keep a log of all the what's the words we've ever done.

[06:30.200 --> 06:33.760] And I was positive that we had done this one before, but maybe a long time ago, but it's

[06:33.760 --> 06:34.760] not in my list.

[06:34.760 --> 06:35.760] So I don't know.

[06:35.760 --> 06:36.760] You guys tell me if you remember doing this.

[06:36.760 --> 06:39.520] If not, either way, a refresher is important here.

[06:39.520 --> 06:45.800] I wanted to talk about the word hominin as opposed to hominid as opposed to hominoid.

[06:45.800 --> 06:48.040] And I know we've all heard all of these words.

[06:48.040 --> 06:52.440] I want to talk a little bit about the origin of these words.

[06:52.440 --> 06:57.720] Back in the day, you probably heard the word hominid all the time.

[06:57.720 --> 07:04.080] Like hominid was the main word that we would use in scientific parlance.

[07:04.080 --> 07:09.960] And within, I'd say about the past decade, we started increasingly seeing the word hominin

[07:09.960 --> 07:17.000] show up first within sort of circles of people who do this stuff for a living and then later

[07:17.000 --> 07:19.960] within like science communication and more sort of like outward things.

[07:19.960 --> 07:23.680] So I just want to kind of give you guys a little bit of background about what these

[07:23.680 --> 07:27.000] words are, what they mean, why we use them the way that we use them.

[07:27.000 --> 07:33.420] So one way to sort of think about this is that hominid, which is the word that we used

[07:33.420 --> 07:36.440] to use all the time, and we still do use, but it means something different.

[07:36.440 --> 07:39.800] They're all current and extinct great apes.

[07:39.800 --> 07:43.560] So pretty much anything you can think of that's a great ape, a human, a gorilla, an orangutan,

[07:43.560 --> 07:49.880] a chimpanzee, a bonobo, homo erectus, homo erectus, yeah, like anything that is current

[07:49.880 --> 07:50.880] or extinct.

[07:50.880 --> 07:51.880] Exactly.

[07:51.880 --> 07:52.980] Like you said, that's a great ape.

[07:52.980 --> 07:53.980] That's a hominid.

[07:53.980 --> 07:55.480] So it's quite, quite inclusive.

[07:55.480 --> 08:01.220] A hominoid is even more inclusive above that because it also includes gibbons, which are

[08:01.220 --> 08:02.560] lesser apes.

[08:02.560 --> 08:07.400] So it's basically all apes, not just great apes, but there is a distinction between gibbons

[08:07.400 --> 08:08.400] and the great apes.

[08:08.400 --> 08:10.960] So hominoids include even gibbons.

[08:10.960 --> 08:11.960] What about hominish?

[08:11.960 --> 08:12.960] Hominish?

[08:12.960 --> 08:13.960] Yeah.

[08:13.960 --> 08:20.440] That's for the ish, you know, actually we're going to be talking about things that are

[08:20.440 --> 08:24.440] hominish later in the show, I think.

[08:24.440 --> 08:30.200] But so hominoids, I'm going to put that one off to the side because it's not used as

[08:30.200 --> 08:34.240] often, but really the distinction here we're talking about is between hominid and hominin.

[08:34.240 --> 08:40.680] So hominid is all current and extinct great apes, but hominin specifically, it's more

[08:40.680 --> 08:49.240] narrow, specifically speaks to anything that follows along the human lineage.

[08:49.240 --> 08:54.300] And this really came about with learning about our genes because historically we were categorizing

[08:54.300 --> 09:00.320] things taxonomically by comparing anatomy, by looking at like shared features, morphology,

[09:00.320 --> 09:01.320] things like that.

[09:01.320 --> 09:04.540] But the more that we started to learn about our genes and learn about kind of where these

[09:04.540 --> 09:08.920] different genetic splits occurred, the more that we started to understand that there is

[09:08.920 --> 09:12.220] actually a difference between a hominin and a hominin.

[09:12.220 --> 09:18.120] So hominin now refers to all the species of modern humans and early humans after the split

[09:18.120 --> 09:21.920] from the common ancestor with chimpanzees about seven million years ago.

[09:21.920 --> 09:25.600] So chimps went kind of one lineage, humans went another lineage.

[09:25.600 --> 09:31.200] So all the things, all the intermediate species that happened along the way, that is a hominin.

[09:31.200 --> 09:36.440] A hominid of course also includes chimps and gorillas and orangutans.

[09:36.440 --> 09:39.480] So that split was much, much, much earlier.

[09:39.480 --> 09:40.480] Does that make sense?

[09:40.480 --> 09:42.320] Like as a bigger branching tree.

[09:42.320 --> 09:47.880] So if you look at the reasons why these names came to be, it all has to do with taxonomic

[09:47.880 --> 09:49.280] categories.

[09:49.280 --> 09:53.440] So hominoids are in a superfamily called hominoidea.

[09:53.440 --> 09:56.280] So that's again the great and the lesser apes.

[09:56.280 --> 09:59.160] Hominids are the family hominidae.

[09:59.160 --> 10:02.520] So that's all the great apes, including human beings.

[10:02.520 --> 10:08.980] Hominins, sometimes you'll see H-O-M-I-N-E-S, hominins are the subfamily homininae.

[10:08.980 --> 10:13.440] And so that's human beings and all of their relatives.

[10:13.440 --> 10:17.440] Hominins comes, oh, actually there's a distinction here too, I should make that hominins are

[10:17.440 --> 10:19.600] actually distinct from hominins.

[10:19.600 --> 10:21.640] Hominins are the subfamily homininae.

[10:21.640 --> 10:23.700] I think chimps are actually included in that.

[10:23.700 --> 10:26.400] So it's everything from the chimp split on.

[10:26.400 --> 10:31.000] And then hominins, which is the word that, you know, I opened this talking about, it's

[10:31.000 --> 10:32.540] actually a tribe name.

[10:32.540 --> 10:37.220] So it includes all bipedal apes within that human lineage.

[10:37.220 --> 10:42.840] And so you'll see that, for example, like the chimpanzee clade is Panini, or I think

[10:42.840 --> 10:46.000] it's Panini, not Panini, but it's spelled like Panini.

[10:46.000 --> 10:47.720] That's Pan, right?

[10:47.720 --> 10:51.360] We've seen like Pan troglodyte, like you've seen those like names.

[10:51.360 --> 10:54.280] And so, and then homo would be a human being.

[10:54.280 --> 10:59.200] So that's hominini or hominini, Panini, I can't even, I just said that, I love it.

[10:59.200 --> 11:01.360] I want to just start calling them Panini.

[11:01.360 --> 11:04.320] Actually I found this really funny Reddit post where this guy's talking about it and

[11:04.320 --> 11:07.780] he said, Panini, it's spelled the same as the sandwich, but it's pronounced differently

[11:07.780 --> 11:10.440] and tastes different too.

[11:10.440 --> 11:11.440] Gross.

[11:11.440 --> 11:12.440] Clever.

[11:12.440 --> 11:17.840] And so yeah, when we look at the etymology, of course, it comes from the same root word

[11:17.840 --> 11:25.800] homo, which comes back from hominini, which is related to the word, I mean, there's so

[11:25.800 --> 11:28.160] many words that have homo in them, meaning man, right?

[11:28.160 --> 11:29.640] Like homunculus, like the little man.

[11:29.640 --> 11:34.660] And then id is a, is just that word forming piece there at the end.

[11:34.660 --> 11:37.520] So hominini is how we get the word hominin.

[11:37.520 --> 11:44.080] And there was sort of a decision made within the paleogenetic world that to be more specific

[11:44.080 --> 11:48.760] when we're talking about the human lineage, we should, we should say hominin because hominid

[11:48.760 --> 11:50.540] is too inclusive.

[11:50.540 --> 11:52.760] It includes all these other great apes as well.

[11:52.760 --> 11:54.240] Did I just confuse you further?

[11:54.240 --> 11:56.280] Well, it's getting more confusing.

[11:56.280 --> 11:58.800] They're just adding names to just parse things out.

[11:58.800 --> 12:03.280] I think it's just like shifting to the cladistic approach where like we're trying to parse

[12:03.280 --> 12:08.720] out all these very specific different clades and as we get more information about the evolution

[12:08.720 --> 12:09.720] of humans.

[12:09.720 --> 12:14.920] It's like, yeah, sometimes our old stuff, it's not quite wrong, but it's like less right

[12:14.920 --> 12:15.920] as we learn more things.

[12:15.920 --> 12:17.640] And so, I mean, you're so right, Steve.

[12:17.640 --> 12:23.840] I even have a quote here from a paleoanthropologist at University College in London who said,

[12:23.840 --> 12:27.240] quote, when we start fiddling with names, everybody gets confused.

[12:27.240 --> 12:31.400] The transition over the last decade from hominids to hominins when we talk about human ancestors

[12:31.400 --> 12:32.700] has been a pain.

[12:32.700 --> 12:36.320] We've had to explain and re-explain and people still get it wrong half the time, which is

[12:36.320 --> 12:37.320] true.

[12:37.320 --> 12:39.000] I mean, it's also just hard to like learn.

[12:39.000 --> 12:43.880] If you've been in a field for a really long time and you've always used a certain lexicon

[12:43.880 --> 12:47.320] and then all of a sudden it's kind of turned on its ear, that can be difficult too.

[12:47.320 --> 12:51.680] So you've got experts within the field even using the terminology wrong because it's like,

[12:51.680 --> 12:52.680] eh, I don't know.

[12:52.680 --> 12:54.720] I wrote 17 books using that other word.

[12:54.720 --> 12:55.720] I know.

[12:55.720 --> 12:56.720] I was about to say that.

[12:56.720 --> 12:57.960] The other thing is it's not just a pain.

[12:57.960 --> 13:02.400] You suddenly render all the previously published technical studies obsolete.

[13:02.400 --> 13:05.400] And now you need like a footnote or an asterisk.

[13:05.400 --> 13:07.600] So it makes it difficult.

[13:07.600 --> 13:15.360] So I totally understand the need to make technical terms increasingly precise and to evolve with

[13:15.360 --> 13:17.400] our understanding of the science.

[13:17.400 --> 13:22.180] But they really do need to make an effort and prioritize stability as well as whenever

[13:22.180 --> 13:28.400] they can just so it doesn't cause confusion and in the literature and also just in the

[13:28.400 --> 13:30.520] public and in general discussion.

[13:30.520 --> 13:32.200] It's an all win scenario.

[13:32.200 --> 13:33.200] You just got to pick your poison.

[13:33.200 --> 13:35.200] You just got to make a proper balance.

[13:35.200 --> 13:37.760] But this has been a particularly confusing one.

[13:37.760 --> 13:41.760] And the truth of the matter is if any of these terms are going to refer to people, right?

[13:41.760 --> 13:44.340] Because we are the most specific.

[13:44.340 --> 13:48.920] And so if you're talking about people, you can use a larger umbrella term and it'll be

[13:48.920 --> 13:49.920] fine.

[13:49.920 --> 13:51.880] It's kind of like primate, for example.

[13:51.880 --> 13:54.480] Like the word primate can refer to an ape or a monkey.

[13:54.480 --> 14:00.500] But if you try and call a human being or a gorilla or a chimpanzee a monkey, then that's

[14:00.500 --> 14:02.920] actually incorrect because they're apes.

[14:02.920 --> 14:03.920] Right.

[14:03.920 --> 14:04.920] Right.

[14:04.920 --> 14:05.920] All right.

[14:05.920 --> 14:06.920] Thank you, Kara.

Science or Fiction (1:18:41)

Theme: Adapting to Climate Change Item #1: Scientists at the University of the Philippines have proposed burying plastic waste beneath sinking islands to keep them above water. Item #2: China is at the forefront of building “sponge cities” – cities that incorporate features that absorb large amounts of water to help reduce storm water damage. Item #3: A glaciologist at Princeton University has proposed building massive miles-long seawalls at the bases of Antarctic and Greenland glaciers in order to delay their collapse, perhaps by hundreds of years.
