This study posits that at one point about 900,000 years ago the human population shrank to just 1,280 people. With those numbers I assume it’s inevitable that everyone would be related to each other after a few generations, if they weren’t already.
If we’re being technical it’s a certainty not a probability. The total number of humans to have ever lived is something like a 100 billion which is 2^36. So, if you go back 37 generations up your bloodline, it’s mathematically impossible for every couple to not be blood related to another in some way.
>For the majority of those living in rural [British] areas, owning a bicycle dramatically increased the number of potential marriage partners, as for the first time they possessed their own means of travelling beyond their local communities. The widening of gene pools which resulted from this process means that the biologist Steve Jones ranks the invention of the bicycle as the most important event in recent human evolution.
assuming there is no incest, if you go back 40 generations (about 1000 years), 2^40 is 1 trillion people. Its estimated that only 100 billion people have ever lived. So yeah, its more than probably.
Before the invention of agriculture, there were about 5-10 million humans. Let’s go on the lower end and assume 5 million to accommodate for migrating to new lands increasing the population size.
So from 200,000 years ago to 10,000 years ago there were about 7,500 generations. If one person has 2 parents, 4 grandparents, 8 great grandparents, 16 G.G. Grandparents, etc. you can see the issue when you go back that many generations. In a world with no incest, a person born 10,000 years ago would need ≈10^2257 unique ancestors from the first generation 200,000 years ago alone.
In actuality, they would only have 5 million ancestors back then. Humans are a very VERY genetically homogenous species . Two troops or chimpanzees 100 miles apart are more distinct genetically than our entire species is from one another.
Probably? How about, “almost certainly.” Up until the mid 1800’s, marrying a third cousin was not even a huge deal. What, you both have the same Great Grandparents? Your village has a population of 863. I’d be surprised if you weren’t hitching up with one of your relatives. People joke about medieval “matchmakers” but it was that old auntie or granny who’s job it was to make sure that your towns’ genetic deck was properly shuffled.
Literally everyone does. If you have 4 grandparents and each of your grandparents had 4 grand parents, tracing that back with and average of 25 years per generation you would have more people than have ever existed before you hit 1 bc. Assuming they were all different and unrelated people.
My father’s side of the family is descended from sephardic jews that migrated from the middle east to brooklyn. First cousin marriage was more than common; it was practically expected. Half of my grandmother’s siblings married first cousins. Her parents were first cousins. It makes plotting out the family tree incredibly difficult. Most genealogy websites aren’t built to accommodate this, and it leads to having lots of duplicate individuals on the tree.
The average age people have had kids throughout history is 27. If we go back to Roman times in year 0, that’s 2025/27=75 generations. Ideally with no incest you would have 2 parents, 4 grandparents, 8 great grandparents, doubling every time, or 2^generation ammount of grandparents.
If we do 2^75 to go back to ancient rome, that means you should have 37,780,000,000,000,000,000,000 (37 sextillion) unique and individual ancestors.
It is estimated that only 117,000,000,000 (117 billion) humans have ever existed so you do the math on that one.
My mom is really into the genealogy thing and we were able to trace our heritage to King Edward II (aka the wimpy weak King of England from Braveheart).
And once you find royal family, there is no question incest is in your family history somewhere.
Everybody does. You ever look up how many humans there would be if there was no incest of any kind? The number is ridiculously high. Like in a trillions
Could have been retitled, “you probably have incest somewhere in your search history.” It became more mainstream after someone wished for it… F-for a friend.
There’s a phenomenon called “pedigree collapse” where over a wide enough scale, incest is more or less guaranteed to dilute a bloodline, meaning all those fantasy stories of a character being of a legendary lineage don’t actually really work because everyone is related to everyone at some level.
yes and sometimes you have to marry ppl bc of strange circumstances. my parents are related bc my mom went through a horrible time that was out of her hands. I would never marry a relative but I don’t judge ppl who have at all.
My great Nana was likely the illegitimate child of one of the lords in the area who was related to the royal family, so probably there. Lol i think most people in the UK have some relation to the past royalty.
We all have tons of it. That’s how we got here. Who cares. It’s not nearly as big a deal as people like to make it out to be. If I remember correctly, all humans are 43rd cousins at the most. A lot of strangers are much closer.
I mean, if you go back far enough it’s a certainty. But you might be surprised how rare it is in the last 2 thousand years or so. Anthropologists that study culture found very few universal taboos, but incest is one of them. Sure it still happened, but the fact that cultures continents away that had previously never interacted, agree on that was interesting to me.
Not probably, 100% certain we do. If no incest, then if you go back 40 generations, a few thousand years, you would have over a trillion ancestors. This is greater than the number of people that have ever lived. The majority of humans are alive today.
Went back in my family tree and about 10 generations ago I found a dude that married his first cousin, but that same bloodline produced former US President Benjamin Harrison, so it probably didn’t do too much damage
100% without a doubt everyone has some form of incest in their families. Going back 30 generations gives you over 1 billion ancestors which is like 900 years ago which the earth is estimated to only have about 300 million humans back then.
That said, you dont share any genetic DNA with any ancestors past something like 13 generations. Could be wrong Im going off of what I think is memory.
First cousin marriages are still surprisingly common, and I’m fairly certain I’ve got at least one in my family history. That being said, I’m not going to go mapping a tree to find out the extent of it. Ignorance is bliss in this case
Have always fucking hated ‘shower thoughts’, not sure i’ve read one i’ve truly found thought provoking or interesting. why can i not turn these off in my feed?!?
btw: only time i read them is accidentally just scrolling thru, can’t count how hundreds of times i’ve been halfway thru 1 and realized ‘oh shit thoughts’.
same question with ‘far side’? huge fan. loved viewing actual cartoon. not gonna read a description! why can’t i turn them off?!?

Go back far enough and all life is descended from the same single cell organism, so that’s a definitely not probably
Cain, Able. Come here sweeties. Mommy is horny.
Well. We are somewhat connected since long long looooooong back. So yes.
Close to 80% of marriages in human history were either cousins or 2nd cousins. When everyone was dying of dysentery you married who you could.
And I take joy knowing that it’s likely much further back then people like Elon Musk who wouldn’t have money otherwise.
They say “keeping it in the family” but there really is only one family.
Not only a little bit. Like, a lot. We’re talking more cousin on cousin action than you can shake a stick at.

Makes sense given how much the population was in ancient times
And maybe it’s still yet to happen as well (future generations, not me…)
And if not, watch out, you will find out you have a hot cousin soon.
Adam and Eve, and the great flood, would be two.
My family’s from Arkansas, so I have no doubt.

My grandmother and grandfather on my dad’s side were cousins. She didn’t have to change her name at all.
Roll on the family gathering for thanksgiving & Christmas
I mean if you want to get technical with it, we’re all related it’s just distant enough not to affect most of us in a negative way
I asked my parents if it was a genetic thing that I was born an extra toe. They said maybe, because apparently their dad had an extra toe as well.
Minute Earth do a video on this. “Ancestry Paradox” or something. There’s two videos.
You definitely have incest in your bloodline
The more closely related you are to a king or queen, the less hard you have to look.

If you believe in the story of Adam and Eve, they had two sons, who did they sleep with to have kids?
I think my parents once told me my dad’s grandma and my mom’s grandma were cousins

Everyone is the product of incest, rape, conquest, suffering and love.
Also stars.

i actually know this for a fact. no, i will not explain
My father’s side of the family is descended from sephardic jews that migrated from the middle east to brooklyn. First cousin marriage was more than common; it was practically expected. Half of my grandmother’s siblings married first cousins. Her parents were first cousins. It makes plotting out the family tree incredibly difficult.

Actually, yes. There’s a Most Recent Common Ancestor who made a bunch of children and those people had children, and so on.

Well I’ve asked my dad, my brother and my uncle about this to check, and he says ‘nope’. …so that’s good.
Unless you have more ancestors than Earth has had humans, you would have to have SOME incest in order for you to be here
My great grand parents were cousins, so, yeah
Im Puerto Rican. Puerto Ricans have 2 legal last names: Father-Mother.
If we want to speak on a technical level, they have 4 last names: Grandpa-Grandma-Grandpa-Grandma
All 4 of my grandmother’s last names are the same one.
Everybody does. You ever look up how many humans there would be if there was no incest of any kind? The number is ridiculously high. Like in a trillions

According to the bible cain, able, and seth had sex with either their sisters, their mother, or their brother’s daughters.
Well uh… we all shared a common ancestor, and a mithcondrial eve mother. So we are all incest
Not surprising. As they saying goes, “be the incest you want to see in your bloodline”
There’s no probably to it. The math says it is so. Not enough people have existed for there to be zero incest.
Sadly, I am aware of precisely when and how that happened.
But it proves nothing. I’m me, the circumstances of my conception are irrelevant.
This is the weirdest “six degrees” you’ll ever play.
The most recent census for the town that two of my great-grandparents came from was 2000 people, so… yeah, probably
My great Nana was likely the illegitimate child of one of the lords in the area who was related to the royal family, so probably there. Lol i think most people in the UK have some relation to the past royalty.
You’ve probably also had raping, pillaging and conquering done somewhere down the line too.
We all have tons of it. That’s how we got here. Who cares. It’s not nearly as big a deal as people like to make it out to be. If I remember correctly, all humans are 43rd cousins at the most. A lot of strangers are much closer.
DNA tests are proving just how common it is: https://www.theatlantic.com/health/archive/2024/03/dna-tests-incest/677791/
something something blue eyes are a genetic mutation most likely from incest i think
I mean, if you go back far enough it’s a certainty. But you might be surprised how rare it is in the last 2 thousand years or so. Anthropologists that study culture found very few universal taboos, but incest is one of them. Sure it still happened, but the fact that cultures continents away that had previously never interacted, agree on that was interesting to me.
…I have pretty decent genetics…. Maybe it’s thanks to this
Nope. Checked it. None whatsoever.
I think I should call some of my cousins now. Gotta do what you gotta do.
I blame my sister that keeps getting stuck in the dryer.
Not probably, 100% certain we do. If no incest, then if you go back 40 generations, a few thousand years, you would have over a trillion ancestors. This is greater than the number of people that have ever lived. The majority of humans are alive today.
My granddad and grandma are cousins once removed
Went back in my family tree and about 10 generations ago I found a dude that married his first cousin, but that same bloodline produced former US President Benjamin Harrison, so it probably didn’t do too much damage
100% without a doubt everyone has some form of incest in their families. Going back 30 generations gives you over 1 billion ancestors which is like 900 years ago which the earth is estimated to only have about 300 million humans back then.
That said, you dont share any genetic DNA with any ancestors past something like 13 generations. Could be wrong Im going off of what I think is memory.

And imma keep that train rolling.
ROLL TIDE
This is not a probably. It’s a definitely. It is statically impossible for you to not have some degree on incest in your family tree.
Have always fucking hated ‘shower thoughts’, not sure i’ve read one i’ve truly found thought provoking or interesting. why can i not turn these off in my feed?!?

same question with ‘far side’? huge fan. loved viewing actual cartoon. not gonna read a description! why can’t i turn them off?!?
You probably have micro plastics in your balls
Remember, if you don’t already have incest in your bloodline, you have the power change that.
I mean, at one point in time there weren’t enough people NOT to have incest
We all do. I’m a family history researcher. We literally all do.
My grandparents were first cousins, does that count?
