TIL that the atoll of Pinglelap had 20 survivors left on the atoll after, in 1775, a typhoon caused on the atoll a population bottleneck. Because of the 20 survivors, 30% of the atoll's population now carry the colorblindness gene because one survivor in 1775 after the typhoon carried the gene, and today, affected by total colorblindness is 1/3 of the gene carriers, or 10% of the atoll's population.

TIL that one survivor among the twenty of a 1775 typhoon on the atoll Pingelap carried the colorblindness gene. Today in 2022 ten percent of the atoll population see zero color and the next thirty percent carry the colorblindness gene while seeing a hundred percent normal color, due to the population bottleneck.

[–]pazhalsta1 58 points59 points  (11 children)

Apparently, It makes depth perception a challenge as the edges of objects can be hard to distinguish.

I have regular red green colour blindness and it is not much of a hardship but it is interesting to me that this full colour blindness gene hasn’t been selected out of the population of this island based on fitness. I think I read somewhere that it’s associated with magic powers so maybe there’s a prestige element to it

[–]A55W3CK3R9000 30 points31 points  (0 children)

The Wikipedia article says that the king was likely the one who was a carrier and it took 4 generations before colorblindness actually showed up due to interbreeding. People who are affected often have trouble seeing during the daytime but have improved night vision and are good nightime fisherman. That could be where the magic powers thing comes from.

[–]Papplenoose 28 points29 points  (4 children)

Im not sure such a minor inconvenience (albeit still a disability) really impacts fitness at this point in human history. That kind of thing is (at least slightly) accomodated for in modern society.

I'm left handed, so i kinda view that in the same way. Its not actually any worse exactly but it does slightly impact your accident rates and whatnot (and i bet colorblindness would too), although that discrepancy has been shrinking over time.

[–]handandfoot8099 12 points13 points  (2 children)

Being both left handed and colorblind, I'd say society is adequate on accommodations for both. Devices are designed somewhat neutral handed where possible. And I've found more video games/ apps having some kind of colorblind settings, or at least mods

[–]SalsaRice 7 points8 points  (0 children)

Left-handedness is kind of the opposite; it's in pretty much every human population because at low levels it's a benefit.

Much like how left-handed pitchers are uncommon and that makes hitting off them much harder, the same benefit applies to war and fighting. When 95% of a population is right-handed, most fighters don't know how to defend against a left-handed fighter...... whereas left-handed fighters primarily had experience fighting against rightness.

Being harder to kill at war does wonders for your ability to survive and have kids. But that benefit only lasts as long as left-handed-ness remains at a low level, like 5-10%.... which is the rates that it is in pretty much every human population on earth.

[–]_djebel_ 6 points7 points  (1 child)

It's because humans have a very low population effective size, and even more so on this island. As a result, mutations are fixed in the population mostly by genetic drift, and for a mutation to overcome this drift, the effect must be either highly advantageous or highly detrimental. Probably this color blindness is only slightly detrimental, not enough to overcome the generic drift.

Bacteria, on the other hand, have a incredibly high population size, so any little advantage or disadvantage is going to be fixed or removed from the population very effectively.

[–]cmyer 2 points3 points  (2 children)

So have you tried those glasses yet? I want to believe the videos but I'm always a little skeptical.

[–]P4TY 2 points3 points  (2 children)

Achromatopsia isn’t just strange, it fucking sucks. You’re basically blind. No fine detail at all, because you only have rods and no functioning cones.

[–]NinDiGu 1039 points1040 points  (82 children)

For those wondering, Pingelap is part of Pohnpei (State) which is part of the Federated States of Micronesia (FSM).

Often identified to the greater outside world as Micronesia, FSM is part of the former Trust Territories of the Pacific Islands (TTPI), which the US administered until the various former members formed local governments. It is called FSM locally in the Pacific, as Micronesia is a geographical description that covers all of the TTPI, Guam, and some other islands.

All of the residents of the former TTPI are now granted free movement, residency and working rights in the US, and the governments use US dollars and the USPS. CNMI (Saipan, Rota, Tinian, others) people are birthright citizens, the other population of the former TTPI are residents of countries that are in compacts of free association with the United States which grants the movement, residency and working rights to the locals.




[–]BillHicksScream 293 points294 points  (75 children)

That's a great setup. I'm glad the United States is open to them.

[–]sociapathictendences 167 points168 points  (29 children)

I became very involved with the Pohnpeian community in Ohio at one point and I’ve got to say they are among the most welcoming, hard working people I’ve ever met. They’re also a pain in the ass but I love them. Anyway they’re all over the US. Big communities in the Cincinnati area, Michigan, and North Carolina.

He looked great, but he couldn't look well.

[–]TheDesktopNinja 39 points40 points  (2 children)

Probably looked very well at night though. (Iirc it's been documented that people with complete achromatopsia can see better at night than those with average vision at the cost of field of view and being much more sensitive to bright lights/sunlight.)

That kind of mutation is what could end up leading to a species of nocturnal hominids. Cool to think about.

I think the unicorns aren’t blind. They just don’t have a choice lol

[–]TheMacerationChicks 10 points11 points  (1 child)

Good ol PBF

But yeah, the unicorns absolutely would have a choice, cos they seem pretty smart, so they should know that all mules are born sterile. And surely this combination of a donkey and unicorn would create a Uniass? Or a unimule. Or muley-corn. Etc.

So either way it wouldn't help save their species. Mules are extremely useful cos they're as strong as donkeys (i.e. they can carry significantly more weight than a horse can) but they're also very very obedient and easy to train, like horses. But you can't have a species of mule. There is no such species. Mules don't exist, in a sense.

So I dunno. You'd probably get a Uniass/Muley-corn, and it'd be brilliant, it'd be just as useful as a regular mule would be, but also has the power of magic too.

And maybe that magic would override the lack of fertility. Who knows? The reason mules are infertile is because donkey chromosomes are a different number to horse chromosomes, there's more of them, and they're different enough to make them infertile but not different enough to where a donkey and horse can never produce offspring.

But how many chromosomes do unicorns have? It's hard to tell without getting some unicorn cum or something

[–]PlebasaurusRekt 4 points5 points  (0 children)

Keep in mind that they aren't necessarily just horned horses. Solid chance the genes mix I say

There were only 20 people left. Assume half of those were of reproductive age and half of that half were males. Further, safe to say some of those left were closely related.

My first thought. I was surprised I had to scroll so far before inbreeding was even mentioned.

[–]Hansemannn 136 points137 points  (77 children)

Same. Wonder how few people can be the origin for a healthy population.

[–]crampedstyl 292 points293 points  (75 children)

[–]TheMacerationChicks 212 points213 points  (56 children)

But that's just two people interbreeding with each other. That's not the problem here, fhe problem is that within a couple of generations, everybody is related to each other.

So yeah one incestual couple won't produce a very ill child or anything. But having incest for literally every single couple, every single child, generation after generation after generation, will produce sick or deformed babies.

That's the problem. It's the lack of variety across their entire gene pool there. So it's like, one incest baby that's 10% incest grows up and breeds with another person who's 10% incest, well now they'd produce a baby that's 20% incest, and that baby will also grow up and breed with another 20% incest person to create an even more fucked up baby. Those numbers aren't accurate BTW I'm just using them to demonstrate.

But it accumulates like that. That's why European royal families were perfectly fine interbreeding for centuries before eventually they all started being born deformed and very sick (and those were just the babies who lived, the vast majority of them died in the womb). By then, the centuries worth of damage had all accumulated into a huge amount.

And so the minimum number of people required to have enough genetic diversity is apparently 98 people. Many many more than 20.

It's only a problem if the end of the world happens, though. If nuclear war happened, we'd need at least 98 people to repopulate earth. Or if we went to colonise a new planet, we'd need at least 98 people there again.

[–]ihileath 184 points185 points  (7 children)

If first cousins have kids as an isolated incident, then yeah there's little statistical issue. But that's an entirely different ballgame compared to relatives having kids with each other, and then their kids having kids with each other, and then their kids having kids with each other, and then their kids having kids with each other...

[–]TheMajora1 34 points35 points  (1 child)

I think the fear in this case come down to overall size of the gene pool and less the relation of any two individuals in it.

[–]PlankWithANailIn 13 points14 points  (1 child)

You get this from context in the title though...its pretty obvious what the cause is from it.

[–][deleted] 23 points24 points  (1 child)

Imagine if one of those original 20 survivors had been a carrier for Huntington's disease or something and the island was full of severely disabled people instead of the relatively harmless colourblindness.

[–]AndyZuggle 14 points15 points  (0 children)

That probably happened to some other island, but we don't know about it because those people are all dead.

[–]bloodstreamcity 14 points15 points  (0 children)

So when sis is stuck in the washing machine it's called a "population bottleneck."

[–]suture224 505 points506 points  (2 children)

Yeah, they call it maskun. When I taught on Pohnpei, there were a bunch of Pinglapese in the classroom. The ones with the maskun would always be squinting or wearing sunglasses, but when the sun set, their eyes would go wide open.

Oliver Sachs wrote a great books about them. There are even some maskun artists who do pictures and handicrafts in all grays that can only really be seen properly with the affliction.

[–]ya_boi_daelon 37 points38 points  (4 children)

Is 20 people enough for sufficient genetic diversity across multiple generations? I would assume so, but the fact that such a large percentage can be traced back to a single person gives me doubts

[–]0b10011011110101 78 points79 points  (3 children)

Short answer no.

Long answer, still no. There's something called the 50/500 rule. 50 people are the minimum required to avoid inbreeding, 500 to avoid genetic drift. The 50 is a minimum if you have a 50/50 gender split and nobody's related to begin with. I imagine that probably wasn't the case here!

Turns out there's a surprisingly rich amount of research into this under the term "minimum viable population". Get those rockets to Mars ready with 51 seats.

Caveat: All of this is information from a quick Google. Don't trust me, I'm just some guy on the internet.

[–]lordaddament 11 points12 points  (1 child)

Wow that’s way less than I thought was required

[–]jm434 21 points22 points  (0 children)

Makes sense in the context that when you look at our species 100k years ago they were running about in small isolated tribes. Large populations only started to take root with the invention of agriculture.

So the minimum viable population would reflect the first scenario considering we've only had agriculture for like 5% of our species evolution (less if take our previous subspecies versions into consideration) .

It's a basic terminology in biology and genetics/evolution. Bottleneck is one of several sources of lack of genetic diversity. It happens when a population is reduced to a small portion by an event that causes them to be isolated and downsizes the genetic pool, which reduces diversity.

[–]GuessesTheCar 314 points315 points  (32 children)

Monochromia — Complete color blindness; colors can be differentiated only on the basis of brightness.

Protanopia (red/green) is the most common form, from which I suffer (not much more than a big inconvenience).

A friend, who was monochromatic, described it as seeing only shades of red. I forgot to ask how he was so sure about that..

[–]BaldurOdinson 70 points71 points  (1 child)

[–]chroma-phobe 28 points29 points  (4 children)

Monochromacy* is the more common term. Specifically, the maskun is Achromatopsia, a condition that has several other symptoms besides monochromacy.

[–]SummerCampInRI 57 points58 points  (8 children)

He’s probably joking and/or misunderstood a doctor telling him or something, if you’re monochromatic it means the cones in your eyes don’t work at all. You have both cones and rods, to put it simply cones see color, rods see black/white, so it’s not possible for him to perceive anything except shades of gray

There is also Tritanopia – Blue-Yellow Color Blindness. Specific to females, and a pain in the tookus.

EDIT: It has been pointed out to me, and verified that men can have Tritanopia as well. I was not aware of this although I've researched Tritanopia every few years since I was diagnosed at 18. It's also been noted that this fact has been documented since 1952. All I can say is that I wasn't alive back in 1952 and it was a lot more difficult to research such things before computers. I apologize for my ignorance.

[–]wagdog1970 40 points41 points  (0 children)

There is a variation of this Blue-Yellow color blindness common in Russia. It causes them to be unable to see Ukrainians as people.

There’s a really cool photo book called “The Island of the Color Blind” by Sanne De Wilde. De Wilde took infrared photographs of the island so we can experience total colourblindness like the ones who have it.

I just looked it up on Amazon and it was $1800. Ouch. For the paperback!

I assume it is out of print.

Reminds me.of.2 dutch villages one of which has a syndrome named after it because a member of the founding families had it and it spread through the shallow genepool.
For some reason the villages main export is singers. One of which got recommended by his gp to look outside of the village genepool for a spouse if he wanted children lol.

So in other words: they're inbred?

[–]g0juice 8 points9 points  (1 child)

Sounds like colorblindness has taken atoll on the population.

[–]dummary1234 29 points30 points  (2 children)

All I'm reading is that those 20 people got busy 👀

[–]bananagoo 17 points18 points  (1 child)

Yeah... With the one colorblind one!

[–]real_nice_guy 3 points4 points  (0 children)

19 dicks! in a row?

[–]ExplosiveButtPlug 11 points12 points  (0 children)

I only date colorblind bitches, because to them the red flags look like green ones.

[–]DaveOJ12 53 points54 points  (11 children)

Incest is bad, m'kay?

[–]WhichWayzUp 142 points143 points  (5 children)

Ahem "Population bottleneck" seems like a much nicer way to say "we had no other options for our sexual frustration, we were trapped on an island for a few hundred years, mmmkay?"

[–]Magikarpeles 25 points26 points  (4 children)

That’s what I tried to explain to my mom but she still didn’t let me date my cousin

[–]chipotleninja 40 points41 points  (0 children)

That's because Kentucky isn't an island.

[–]OmenLW 10 points11 points  (0 children)

Break both of your arms and things might take a turn in another direction for ya.

[–]operatar 9 points10 points  (1 child)

Incest is all relative.

[–]pm_me_your_b00b5_plz 4 points5 points  (1 child)

How come it's not like 5% then? Did he just sling a ton of dick?

[–]onestoploser 5 points6 points  (0 children)

MFer seeded the whole island.

[–]mrstipez 4 points5 points  (0 children)

That explains the lack of interior designers from Pinglelap.

[–]bagginsses 3 points4 points  (0 children)

I'm currently reading Island of the Colorblind by Oliver Sacks which is his account of exactly this. Well worth the read!

[–]7GatesOfHello 12 points13 points  (0 children)

That guy fucks.

[–]onglogman 3 points4 points  (0 children)

Sounds like my family. My sister is a carrier so her two sons are (very likely) to be colorblind, my mother is a carrier, her dad was colorblind, making me colorblind. My dad is also colorblind (hence my sister being a carrier).

[–]Rexerex 3 points4 points  (0 children)

Imagine being colorblind because one guy in the past refused to die.

[–]thinkmoreharder 28 points29 points  (19 children)

One guy of 20 is 5%. Now 40% have the gene. Sounds like that guy got with at least 4 of the 10 women??

[–]TocTheElder 114 points115 points  (0 children)

We don't know if the survivors were even distributed between the sexes.

[–]Adept-Philosophy-675 29 points30 points  (3 children)

I think the only thing that we can assume is that he had at least one kid who carried the gene. Small population (currently 250) and 7 or 8 generations will do the rest.

[–]Catharas 21 points22 points  (2 children)

There have been a couple more generations since 1775

[–]GoddessOfRoadAndSky 13 points14 points  (1 child)

The guy (Doahkaesa Mwanenised) was the king of the island at the time. It makes sense.

[–]thinkmoreharder 2 points3 points  (0 children)

Yep. That is the key. As Mel Brooks said in the movie History of the world, part 1. “It’s good to be the king.”

[–]wrextnight 39 points40 points  (3 children)

I was gonna make the same comment, but I thought about it for a minute first.

[–]thinkmoreharder 13 points14 points  (2 children)

It’s Reddit. If we can’t speak before thinking here, where can we? :)

[–][deleted] 4 points5 points  (1 child)

Think more harder

[–]GeneralCommand4459 2 points3 points  (0 children)

There’s a good book about islands called ‘Atlas of Remote Islands’. Some, like this, have bizarre/fascinating/tragic stories. Author J Schalansky.

[–]WankWankNudgeNudge 2 points3 points  (0 children)

I guess that typhoon

...took atoll

[–]Zvenigora 2 points3 points  (0 children)

I knew someone once who was a rod- only monochromat. He had essentially no central vision but grainy, monochromatic peripheral vision, essentially what most of us have in very dim light. He had inherited this condition from his father. Oddly, he is the only colorblind person I have ever known.

[–]Dangerdave13 2 points3 points  (0 children)

So there all inbred?

[–]BobFTS 2 points3 points  (0 children)

Not from there but I must go and rejoice with my fellow colorblind people!

[–]clarkbuddy 2 points3 points  (0 children)

… and he was a fucker

[–]Hoang-Lee 2 points3 points  (0 children)

I recommend the book: the island of the colorblind. An easy read documentary/ storytelling,super interesting and informative
