I used to work with this absolute idiot when I was a kid. He was married to his cousin. But apparently he was such a gross dude, that it was too much for her, so she left him. For his brother. She ended up having a couple kids, one with each brother.
Talk about going out of your way to keep it in the family. Their family tree was tied in a knot.
A lot of people here are saying that the more genetically similar you are to somebody, the more attractive they are (so long as you don’t grow up with them). I’m here to tell you that those guys are completely wrong
Studies have shown that (in other animals unfortunately, not in humans) that the more genetically dissimilar two individuals are, the more attracted they are, so long as they can produce viable offspring (aka they can have kids)
This study would also be done on humans, but that would be slightly morally questionable
This is an evolutionary trait in order to incentivise us to increase the gene pool when possible. You can imagine what would happen if we only rucked our cousins (look at the royals)

Yeah you often strive for maximum compatible difference. There’s no instinct to create a family ladder
Heh, second cousin is far enough.
Second cousin means cousin second order (grandchild of a sibling of one of your grandparents), right?
Another way I like to think of it is it’s your parent’s cousin’s kid. So you can see why from their perspective it would feel more closely related, it would be like you having a kid and your cousin having a kid and then you seeing them together.
Yeah, genetically don’t make a habit of it, but you’re probably fine (unless your grandparents are identical twins or has hapsburgs or something), but also I’d be super uncomfortable if it was my kid
Yes
Thanks!
A parent’s first cousin. Your first cousin’s child would be a first cousin once removed.
What really confuses me is your second cousins parent is also called your first cousin once removed.
Second cousin’s parent is great aunt/uncle
No, your great aunt/uncle is your second cousin’s grandparent.
Second cousin is your parent’s cousin’s child.
Your parent’s cousin’s parent is your parent’s aunt/uncle, which is your great aunt/uncle.
You’re parent’s cousin is your first cousin once removed.
Eh second cousin marriage isn’t a big deal in some cultures
*Most of cultures
Erotic fan-fic at its finest.
banjos quietly play in the background
That happened to a few of my cousins years ago. We were at a family function so I thought they would’ve put two and two together, but alas.
A few? Not just two??
I saw that after pressing send and thought to myself, ah, no one’ll pull me up on that.
It’s ok I wouldn’t want to admit it if my family reunion turned into an orgy either
They just got a good vibe, you know?
Sounds like it, cuz.
Second cousins is kissing cousins, have at it!
This is the only one that isn’t fake
Reminds me of the time I fucked my cousin a few times. She moved I now miss her.
Isn’t there some sort of biological thing where you’re more likely to be sexually attracted to your relatives if you don’t know they’re you’re relatives
Second degree cousins is not that close though. If every generation has three children, that’s 27 persons. I thinks that for most of human history excluding second degree cousins from the acceptable partners pool would have been impossible. Communities were not that big.
Second degree cousins
I can’t stop laughing.
That’s how it’s phrased in many other languages, german for example.
French also
And if my maths is correct, you only share on average 12.5% of your DNA with them
your math may be wrong, because we have very similar genomes, even compared to complete strangers. hell, even between some species.
Well, yes. I meant in the sense we share on average 50% with each parent/siblings, 25% with grandparents, etc. I should have said genetics instead of DNA.
Of the variable alleles, not all DNA
iirc 90% of dna is the same even between humans and plants. (Don’t quote me on that)
Groups often came together to party and marry people.
There are even rules, like exogamy is common.
All I could find on this is something called “genetic sexual attraction” [1], though Wikipedia contains arguments that it’s pseudoscience [1.1]. Here’s a Reddit post asking about this. [3].
Related to this, I also came across the “Westermarck effect” [2] which appears to suggest that people who grow up together are less likely to be romantically attracted to each other [2.1].

- §“Criticism”
Critics of the hypothesis have called it pseudoscience. In a Salon piece, Amanda Marcotte called the concept “half-baked pseudoscientific nonsense that people dreamed up to justify continuing unhealthy, abusive relationships”.[8] The use of “GSA” as an initialism has also been criticized, since it gives the notion that the phenomenon is an actual diagnosable “condition”.
Many have noted the lack of research on the subject. While acknowledging the “phenomenon of genetic sexual attraction”, Eric Anderson, a sociologist and sexologist, noted in a 2012 book that “[t]here is only one academic research article” on the subject, and he critiqued the paper for using “Freudian psycho-babble”.

The Westermarck effect […] is a psychological hypothesis that states that people tend not to be attracted to peers with whom they lived like siblings before the age of six.

Yeah, that’s weird: genetically similiar people are more attractive (as long as it isn’t too similiar)(people in stable relationships often look alike) but bigger genetical difference is better.
Yes, one of the primary components of attraction is familiarity. Also proximity and similarity.
Oh hey look. The story of how Rudy Giuliani found his wife!
Edit: ex wife, sorry forgot the church didn’t condone their boning like they wanted so they had to get a divorce.
Second cousins you don’t share even blood
Comment:
Second cousin in my country is a cousin from the part not related to any of my parents of one of my cousins. What is weird of that?
For example, my cousin is one of my father’s brother son, then my second cousin has to be (otherwise would be a cousin too) the daughter of the cousin’s mother’s brother.
If I pick a random girl I would be equally related genetically.
Uh…yeah you do. Just not very much of it
I don’t share my blood with anyone. You keep your grubby hands to yourself.
People like you are why vampires are almost extinct. Be considerate and share a little.
Dude second cousin in my country is a cousin from the part not related to any of my parents of one of my cousins. What is weird of that?

A second cousin is someone with whom you share a great-grandparent.
Earliest common ancestor is great-grandparent. With same number intermediaries for both people.
n^th cousin is how many “g’s” in the title of the earliest common ancestor. Grandparent == one “g” = first cousin. Two gs, second cousin, etc.
“Removed” is the offset value, or the difference between how many intermediaries between the two parties and their earliest common ancestor.
Well yes, but ‘second cousin’ with no qualifiers implies we’re talking about zero times removed. The more salient point I was trying to make was that yes, second cousins share blood
Careful anon, that’s how you get a Habsburg child
I mean, probably not with a second cousin, unless you do it for hundreds of years. Greater risk of birth defects if you have children over 30.
Yeah even first cousins are actually not that bad, biologically speaking, if it’s only done for one (or probably even two?) generation.
AFAIK the risk is about the same as having a kid after 40.
Yup, and AFAIK, it’s legal in some areas to have kids with your first cousin.
Probably legal in more places than it’s illegal
It is, in fact, legal more places than not. Cousin marriage was extremely common for thousands of years. It only really started to drop off when people started owning cars and could meet people from further away. Most places still haven’t changed their laws because the cultural change was so recent, and because it’s low risk enough that it’s not a serious concern if it’s just once in a while rather than, say, medieval European royalty shenanigans.
And at this point, with all of the toxins from food processing/preservatives and the plastics getting into our bodies, the added risk is probably negligible.
