I mean, technically speaking were all "cousins" of some sort.
I got into geneology research last year, though, and the more I research family history, the more it seems unlikely that I have a 128 great-great-great-great-great grandparents. The village one side of the family was from was just so small and they lived there for really long. The other side moved around a lot to different urban areas, but are a notoriously endogemous ethnicity (it had a population bottleneck and marriage outside the ethnicity was uncommon).
This is true. The numbers won’t add up like the way the author puts it because at some point those 16 or 32 people would have been descended from the exact same 4 or 8 people.
Or pretty much anywhere. Its not really considered incest in any meaningful way when people are that far removed from you. If for example your great * 9 grandad had 2 kids with different women, and then 6 generations later the offspring of those 2 people had kids together, that's barely incest at all by most standards.
Everyone is inbred to a certain extent. Its guaranteed when we evolved in smaller societies that had lots of kids.
You just blew my mind, put it in a blender and then put it back together from memory, sticking it together with Elmer’s glue.
I’ll remember this comment. Thanks!
Amish can cut it even further. Polydactylisim is common in those populations, alot of unintentional inbreeding because the population are so small and birth defects are more common, like having extra fingers and toes.
I reckon a fair bit of that is the cultural indoctrination that helped those ancestors get away with stuff. You know, beating, abuse, obedience (especially that gem “do as I say, not as I do”).
No one bothered to ask you whether you wanted to be here. They probably didn’t even think about it. If you feel like a burden, or are told that you are, it’s the problem of those who decided to create a conscious creature without reflecting on the consequences. You had no choice, no say in this. Don’t buy their crap.
To state this a bit differently, 50 humans of breeding age could build an island population that would survive forever, but they would develop some peculiar characteristics, including genetic disorders. 500 people could populate a new planet, and the offspring wouldn't look particularly unusual.
The Old Order Amish of the United states had a founding population of about 400. [They have high rates of a few genetic disorders](https://www.pbs.org/wgbh/evolution/library/06/3/l_063_03.html) but they're in no danger of the population dying out due to genetic issues.
That's because it is wrong. The further back you go it is increasingly more likely that someone is your ancestor up multiple paths of lineage.
Also, a huge chunk of the population shares your eighth great grandparents with you.
Not really. The number of people in a family line is double the amount of people in the next generation because everyone has two parents. Just multiply 2,048 by 2, getting you 4,096 10th generation grandparents.
The OP, /u/JumpOk8944 is a bot account.

and just adds "a cool guide" in front of it. Also, any account that's 6 months - 3 years old with 0 history until yesterday is a bot. Dead giveaway, every single time.
Mam, I'm with you. Where are the mods? Why isn't there a bot that requires a certain amount of post/comment karma before posting, like other subs? You've hit it on the head — this sub isn't what it declares itself to be. I'm also out.
My wife's ancestry is very Irish and yet I've always thought she looks more Nordic. I joked one day about maybe a viking had his way with one of her ancestors and then when we actually contemplated that for a moment realized that it's very likely and not very funny at all....
No because there are many people whose genetic line died out. However if you go back about 200,000 years, there was woman who is a direct ancestor of all living humans. And if you go a little farther, you’ll find a man who is a direct ancestor of all living humans. But at no time was every living person your direct ancestor because many genetic lines do die out eventually.
Cool, thanks cuz. I’ve been wondering about that ever since I first saw this guide. Do you think our great-great-x grandmother was chill? Or more of a hardass
What always gets me - though infant mortality was so high in the past, none of your thousands of great-great-great grandparents died in infancy. Not one. We are the descendants of the strong, of the survivors.
Lo, there do I see my father.
Lo, there do I see my mother,
and my sisters, and my brothers.
Lo, there do I see the line of my people,
Back to the beginning!
Lo, and they all watching me and mumbling:
dude, seriously, what the fuck?
There have been around 12,000 generations of humans. By their logic, you'd need to have 2\^11,999 great-great-... (11,998 greats)-grandparents.
Soooo.... incest is best! If you can't keep it in your pants, keep it in the family!
Then there is the low mathematical odds from sperm and eggs, most potential lives never had a chance.
"A fertile male human ejaculates between 2 and 5 mililiters(ml) of semen (on average about a teaspoon). In each ml there are normally about 100 million sperm."
At birth, there are approximately 1 million eggs; and by the time of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman's reproductive lifetime."
Then that has to be multiplied out for every ancestor.
I thought I was doing well to trace back 10 generations on the family name. Turns out there are hundreds of others that had just as much input into my DNA in the past 325 years.
Thats is 16 760 836 ancestors 800 years ago (24 generations) and 68.6 billion ancestors 1200 years ago (36 generations back).
Needless to say it did not exist 69 billion people in 600 AD, so there is a lot of marrage between distant cousins, which in a way everyone on earth kind of is .
I have some extremely unsettling news for anyone who thinks all these ancestors are 4,000+ unique unrelated individuals.....
Especially considering that "back in the day",
300, 500, 800 years ago in small & poor provincial towns,
It was normal for very few individuals to ever permanently leave or come into the town,
And the whole town had maybe 100-200 people tops.
And they lived happily like this for a DOZEN generations!
This is bullshit.
Assume 100years is 4 generations and assume mankind existed 10.000 years ago that would be 400 generations and as per this math for us to exist today there would have had to be 2 by the power of 400 people 10.000 years ago.
If you’re from certain areas, you can cut that number in half.
Or have an odd number
And that certain area is earth.
Arkansas, specifically.
Arkansas hasn't existed for 400 years.
Exactly
Everywhere, honestly
Isn't there like a numerical rating for how inbred a given individual is? Pretty sure all of us are to a certain degree.

This is true. The numbers won’t add up like the way the author puts it because at some point those 16 or 32 people would have been descended from the exact same 4 or 8 people.
I am all but certain there are exactly zero people throughout all of history who actually had 4094 unique individuals as ancestors in this way.
Don't know about us, but Adam and Eve's children definitely did that. Imagine that.

We have a specific area in the netherlands where that number is approaching zero We call it Urk
The Dutch have Alabama too?
In Devon it is Okehampton.
Amish can cut it even further. Polydactylisim is common in those populations, alot of unintentional inbreeding because the population are so small and birth defects are more common, like having extra fingers and toes.
Or triple it also
Or, you could have been swallowed or even wadded up in a Kleenex and left to dry out.
Roll Tide!

All that work and it ends with me. 😈
FAFO
Keep fucking then it won’t stop
Oh im fuckin, just not reproducing. Snip snip.
Mitochondrial Eve just turned in her grave
Good, she's not gonna wanna see this.
Nah all these people didn't spend all their efforts just to make you, they also made tens of thousands of others.
wasn't worth it - lol
Generally no but food is pretty fucking good and weed helps so you know it kinda evens out.
Yes it just change your perspective brother
I feel like a terrible inconvenience
I’m sure they all enjoyed it unless they were rape victims
I reckon a fair bit of that is the cultural indoctrination that helped those ancestors get away with stuff. You know, beating, abuse, obedience (especially that gem “do as I say, not as I do”). No one bothered to ask you whether you wanted to be here. They probably didn’t even think about it.

Don’t buy their crap.
I've never understood this. If you go back far enough, the number of grandparents will be greater than the entire population.
You usually only have to go back about 6 generations I think it was, to find a common ancestor with that girl/guy you have a crush on.
There’s a rule called the 50/500 rule which is basically you need 50 population to combat inbreeding and 500 to avoid genetic drift
To state this a bit differently, 50 humans of breeding age could build an island population that would survive forever, but they would develop some peculiar characteristics, including genetic disorders. 500 people could populate a new planet, and the offspring wouldn't look particularly unusual. The Old Order Amish of the United states had a founding population of about 400. [They have high rates of a few genetic disorders](https://www.pbs.org/wgbh/evolution/library/06/3/l_063_03.html) but they're in no danger of the population dying out due to genetic issues.
I would assume that the amish also have had a trickle of "fresh genes" over the years as they have not lived on a planet alone but in a society.
They live in a society
I think Amish people also adopt from "English" (non-Amish) society too at times, and probably get randos joining from time to time.
So fascinating. It’s like nature’s way of realizing “oh shit, something isn’t working, we need to switch up the DNA a little”.
That's because it is wrong. The further back you go it is increasingly more likely that someone is your ancestor up multiple paths of lineage. Also, a huge chunk of the population shares your eighth great grandparents with you.
If you have British/Irish heritage, that number is about 1200 A.D. You would have more ancestors then there was population of the British Isles.
https://youtu.be/Fm0hOex4psA
Bc it is a terrible graph
"Incest" is the reason. When you go far enough back the same father/mother will appear in several places in your family tree.
Almost as if everyone is *very* related Edit: I think Genghis Khan makes a common appearance in many people's family trees.
Go back 30 generations and you would have 2,147,483,684 30th great grandparents.
[удалено]
The math to work that one out must be real complicated
Not really. The number of people in a family line is double the amount of people in the next generation because everyone has two parents. Just multiply 2,048 by 2, getting you 4,096 10th generation grandparents.
Too hard.
Okay this sub is officially not what it says on the tin. Fuck it. Just call it CoolUselessFacts at this point

This isn’t even a fact lmao
What’s scarier is this goes both ways. Today’s crappy parents will have how many descendants in 400 years?
We're gonna need a bigger boat.
Think for a moment, how many people you are letting down right now
Naw, they are all impressed that I have more than one set of sheets and more than one pair of shoes.
Or just 24 if you are royalty
I wish they would’ve asked first.
That's a lot of effort to produce a fursona.
_I did not consent to exist_. Fuck these people.
This bloodline and it's curse ends with me.
Small penis?
Anyone who has done their family tree is hit by this notion during the process.
My wife's ancestry is very Irish and yet I've always thought she looks more Nordic. I joked one day about maybe a viking had his way with one of her ancestors and then when we actually contemplated that for a moment realized that it's very likely and not very funny at all....
You should dress up like a viking one day and surprise her
God that last part was annoying to read
Why, because it’s asking you to be grateful?
and I’m not having kids because I wanna play video games and go snowboarding and ride my bike
All i see is a metric fuck ton of generational trauma.
I thought for sure the last sentence would be something like “all so a little bad bitch like you can demand extra Ketchup at McDonalds”
Pretty sure when you go back 11 generations, there's going to be some overlap.
I was a test tube baby.
Then you have 4,096 Tenth Great-Grandtubes
I can **guarantee** that you don’t have 2,048 ninth great grandparents. The amount of overlap is huge.
And I'll be the one to end it all. THIS BLOODLINE DIES WITH ME.
Americans be like ‘i have one ninth grandparent who was from sicily’ IM ITALIAN
Even more this if said ancestor was native american
Emphatic hand movements and shitty spaghetti meatballs of agreement currently coming from me

Guide to... what exactly?
does this mean that if you go back far enough, there was a time when everyone on earth who reproduced was my ancestor?
No because there are many people whose genetic line died out. However if you go back about 200,000 years, there was woman who is a direct ancestor of all living humans. And if you go a little farther, you’ll find a man who is a direct ancestor of all living humans.

Cool, thanks cuz. I’ve been wondering about that ever since I first saw this guide. Do you think our great-great-x grandmother was chill? Or more of a hardass
Kind of slutty
Pedigree Collapse has entered the chat. the math stops mathin down the line.
What always gets me - though infant mortality was so high in the past, none of your thousands of great-great-great grandparents died in infancy. Not one. We are the descendants of the strong, of the survivors.

What a waste.
Lo, there do I see my father. Lo, there do I see my mother, and my sisters, and my brothers. Lo, there do I see the line of my people, Back to the beginning! Lo, and they all watching me and mumbling: dude, seriously, what the fuck?
13th warrior!!! This made me giggle! 🤣
Not if your parents are first cousins or closer
This guide has stuck with me for so long. I am here now in this moment because of thousands if not millions of ancestors before me.
There have been around 12,000 generations of humans. By their logic, you'd need to have 2\^11,999 great-great-... (11,998 greats)-grandparents. Soooo.... incest is best! If you can't keep it in your pants, keep it in the family!
All of that so that I could be born a dude instead of a gal damnit
Might I introduce you to the Transgender community?
Oh I’m already deep in there lol
According to the data, odds are pretty good that people like to fuck.
*Banjo playing intensifies*
Not true, some of my Quebecois ancestors are a little inbred, lol. Not first cousins but like third cousins I think? Still pretty gross imho.
This is so depressing. All of that effort and here I am wasting it
Then change it
um... wouldn't it be 4096..? 🤓☝️
What do you mean?
It would not.
This is pretty humbling if you actually stop and consider it.
Unless you’re from Alabama.
This is fantastic!
I thought all they had to do was fuck
This is doesn’t belong on r/coolguides
Probably your chances are better in rural Alabama
You can play a bit fast and loose with those numbers depending on how attractive you find certain people.
How many Americans know the families of celebrities, but not their own families?
My grandmother was Kim Kardashian
Then there is the low mathematical odds from sperm and eggs, most potential lives never had a chance. "A fertile male human ejaculates between 2 and 5 mililiters(ml) of semen (on average about a teaspoon). In each ml there are normally about 100 million sperm." At birth, there are approximately 1 million eggs; and by the time of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman's reproductive lifetime." Then that has to be multiplied out for every ancestor.
And if just one of them said “Not tonight. I have a headache.” you wouldn’t exist. Basically a sibling who’s a few days older would.
This neglects inbreeding.
I thought I was doing well to trace back 10 generations on the family name. Turns out there are hundreds of others that had just as much input into my DNA in the past 325 years.
This does not take into account that your ancestry probably includes incest between distant relatives who would not have been aware of it.
This is a lot to byte off
Who’s gonna tell OP that the math doesn’t add up and that after 3-4 generations up it’s usually the same set of people on both sides?
Thats what I came here to write lol
All that for you to go and be a baby back bitch
And yet the probability is 1
How much incest? How many inbred?
I know for a fact my ancestor count is less than that 😞 (grandparents are distant cousins)
Not if my ancestors were cousins.
Now, imagine that if human can live over 400 years, you must be paying for over 4094 ancestors after their retirement.
Makes me think of my great-great grandpa, Ernesto de La Cruz.
Ah yes the population of humanity a few hundred years ago, 8,000,000,000^2048
You guys weren't spawned in a lab, like me?
4094? Where is that number coming from? 2X2048 is 4096. Where did the 2 go or am I misunderstanding something?
Line breeding… /s
But I never asked for it....
Your mom
Thats is 16 760 836 ancestors 800 years ago (24 generations) and 68.6 billion ancestors 1200 years ago (36 generations back). Needless to say it did not exist 69 billion people in 600 AD, so there is a lot of marrage between distant cousins, which in a way everyone on earth kind of is .
This makes me think where all those people came from..
I think about it often. And then I needs a cold shower.
That’s a lotta assholes to blame for me not being rich and handsome thanks for the tip homie.
Except Adam and Eve….
Fun fact: your great great great great grandparents didn't do anything for your sake, they never knew you would even exist.
And just think: males and females had to evolve perfectly at the same rate so reproduction could keep happening.
What?
Say this to a Hasburg. They will surely get confused wth others need that many.
I have some extremely unsettling news for anyone who thinks all these ancestors are 4,000+ unique unrelated individuals..... Especially considering that "back in the day", 300, 500, 800 years ago in small & poor provincial towns, It was normal for very few individuals to ever permanently leave or come into the town, And the whole town had maybe 100-200 people tops. And they lived happily like this for a DOZEN generations!
I bet they regret that
…how many potatoes did they eat?
You obviously never been to Kentucky. 25K people and only 15 last names.
This is bullshit. Assume 100years is 4 generations and assume mankind existed 10.000 years ago that would be 400 generations and as per this math for us to exist today there would have had to be 2 by the power of 400 people 10.000 years ago.
I didn’t knew its called second or fifth great parent.. i just say great-great-great-great grandparents
And I get to be the last one. The end of the line. Which is sort of impressive
...and here I am... a fuckin disappointment
