I kept one dude and like 5 women in the family room to populate the entire vault, then I would kick out people that didn’t have the same last name and then eventually kicked out all the males so it was just a 200 dweller vault of sisters
yeah, it’s about 28 generations ago, if we assume a generation to be about 25 years, where the number of ancestors you would need to have for a family tree without overlaps becomes more than the number of people alive on earth at the time. 228 is roughly the number of people alive on earth in the year 1326, which is 28×25 years ago. that’s the theoretical limit of how far back you can go without someone fucking their cousin of some degree, and it requires an exceptionally well-traveled family
All my ancestors up to 6 generations back were born in the same 200 kilometer radius circle. Most of them did not die in the town where they were born.
People move. They are displaced by war and natural disaster, they go on pilgrimages, they go to the city to get rare goods, they migrate to places with more prosperity and more jobs, they learn trade skills from schools or from experts, they find causes they believe in or causes that pay well, they go to festivals and plays and celebrity performances, and they marry.
This was true in the 19th century, but also in the 15th and the 6th and the 40th BCE. Migration is normal. People live rich and complicated lives. For a peasant, one of the sons might inherit the farm, but his wife is from out of town and the other siblings find other things to do that take them elsewhere. Serfs may be bound to the land, but a lord will usually offer dispensation if it is in his interest, and arrange for festivals to keep his stock fresh. And slaves were traded often to prevent them from forming attachments. And burghers, clergy, and nobility naturally tended to travel far.
Yeah. From what I recall from uni classes on this ten years ago (so we might well know more now) that couldn’t be totally ruled out for the very earliest forms of life but we are as certain as we could be about bacteria just being one tree, and likewise for archaea&eukaryotes.
It’s not incest when you get to the point where overlapping lines are mathematically impossible
Reminds me of when I played Fallout Shelter, I made a spreadsheet to keep track of all my vault dwellers’ families.
With the population of a tiny town, it did not take very long at all for the whole vault to become one clan.

That sounds like a proper vault.

In reality, usually it’s staying inside of a small village of maybe a few hundred. Easily within 10 generations, the entire village is related.

At some point back, you are related to every human who was on earth.
At some point back you are (probably) related to every living thing on earth, and at the very least every animal and plant and fungus.
The only exception would be if life had evolved more than once on earth, which is totally possible but we would probably be able to tell.
