    What’s interesting is that historically a lot of people never had children. But, by definition, none of your ancestors were among them.

    So, even if being a childless femboy slut was incredibly common historically, that’s the one thing none of your ancestors would be able to understand.

    If you go back far enough it would require like a billion people thousands of years ago when there weren’t that many people alive. I’m confused now

      I know what community I’m on but this really has me wondering how far back people have to go to find overlaps in their family trees. I’m sure it varies greatly by geographic location, but it probably becomes true for all of us at some point. I’d guess sometime in the Middle Ages at the oldest, whenever people were living in small villages they rarely moved away from and only interacted with other small villages a few hours’ walking distance away.

        Inbreeding generally stops being a notable factor around 4th degree relation between parents. Even first cousins, 3rd degree relatives, only have about a 6% risk of an anomaly at birth when having a child together, compared to the 3% normal rate for all pregnancies. There’s likely been a LOT of inbreeding in any one person’s family history.

        The nice thing is that once a new non-relative is added to the mix, the risks associated with past inbreeding largely go away; you only pass on 1 copy of your genes to your kid, so even if you’re personally affected by a family history of inbreeding giving you a bunch of identical copies, if your kid’s other parent isn’t related to you, their copies should be different from yours, and the kid will have 2 different copies just like anyone else, helping protect them from recessive familial conditions and the like.

      Yeah, but on the other hand if you have a sibling - by this logic - it would be counted as another 4096 additional “past people” but it isn’t. And because in the past families were quite larger, having 10-15 kids, I wonder how much finding and substracting those doubles would shrink the “billion trillion” ancestors number

        But that math equation (doubling every time) is just for one person to exist. It’s not making any assumptions about shared ancestry or the current population vs the ancestry population

    LOL, I have heritage from Newfoundland, which I learned of as an adult (the heritage that is, not the existence of the very large island in the north Atlantic).

    Apparently there was nothing to do on that rock for three hundred years except fuck your cousin. Based on what I’ve seen, nowadays they fuck their cousins or move to Alberta.

      I’ve read that in Iceland basically everyone is related if you go back far enough and people often look up what degree of cousin they are so they can see if it meets a level they’re comfortable with or feel like they’re too closely related to risk producing offspring.

        I heard some of that was a bit of humor that didn’t quite translate, but I’m sure it’s at least in the back of your mind, and you might want to consider whether being 3rd cousins, double-4th cousins, and quntiple 6th cousins starts to add up, LOL.

        I found out my stuff through DNA to track down my biological relatives when my daughter was young, and I still have people on there where the percentage makes zero sense based on the documentation I can find, unless there’s a bunch of stuff farther back piling on the centimorgans.

    If you pick any random body part and look at it carefully, you’ll come to realize that countless people who had this body part in a slightly different and thus disadvantageous shape, had to die in horrible ways so you could have yours in the shape that it is today.

    Several of them will be the same person, sometimes across generations. Way more if you are descended from nobility.
