Got interested in genealogy recently, and this chart boggles my mind

So if you go 12 generations back, it took 8,190 people surviving famine, disease, and war for you to be here today playing on your phone while taking a shite. Keep going beyond 12 generations, and it’s truly amazing to do the math.

The interesting thing would be to know how many made choices to die before their time that you could live now.

My ancestor who signed the Declaration of Independence for one. Another on the Titanic.

They gave so you could live. Not sure if the weight of all that is an albatross or a blessing.

not sure they had too many options in that scenario

But if you keep going back the math becomes impossible with the human population that was in whatever country on whatever continent on this one planet your ancestors hail from.

So, we’re all related and all our great-great….great-grandmas (or grandpas) were incestuous sluts!

Arkansas folks’ genealogy is much less complex.

It’s truly a miracle just to be alive. We should cherish it but a lot of people don’t because they don’t understand everything it took for them to even be born.

1000 years of ancestors would probably be about 40 generations.
That would be about 1 trillion 38th great grand parents.

There have never been close to that total number of humans in all of history.
So, how does that work??

I always estimate 3 generations per century.

So roughly 4096 ancestors takes you back 333 years to about 1690.

That's alot of kin folks!

It's more complicated because not every one of those ancestors was totally unique. I will let Scientific American describe it:

quote:

Imagine counting all your ancestors as you trace your family tree back in time. In the nth generation before the present, your family tree has 2n slots: two for parents, four for grandparents, eight for great-grandparents, and so on. The number of slots grows exponentially. By the 33rd generation—about 800 to 1,000 years ago—you have more than eight billion of them. That is more than the number of people alive today, and it is certainly a much larger figure than the world population a millennium ago.


In other words, the numbers are impossible. There were not 8 billion people alive 1,000 years ago, yet the numbers say you are descended from that many people. So how do we resolve this paradox? Simple, inbreeding. Everyone is inbred more than we think, which means the same person will be on multiple spots on your family tree.

quote:

This seeming paradox has a simple resolution: “Branches of your family tree don’t consistently diverge,” Rutherford says. Instead “they begin to loop back into each other.” As a result, many of your ancestors occupy multiple slots in your family tree. For example, “your great-great-great-great-great-grandmother might have also been your great-great-great-great-aunt,” he explains.

some of your great grandparents are the same person as your other great grandparents
