Everyone alive today has had a living ancestor at every point in history
Going back to the very beginning of time.

Every person alive has one biological mother and one biological father. Four biological grandparents. Eight biological great-grandparents. Sixteen biological great-great grandparents, and so on all the way back.

So the number of living ancestors you had living on Earth at a given time can be expressed as 2 to the power of g where g equals the number of generations back you want to go.

But wait. If you conservatively estimate that there are 5 generations per century, going back 600 years or 2^30, you'd have had 1,073,741,824 living ancestors on Earth in 1418.

But the entire population of Earth then was only about half that. How can this possibly be?

Your math and reasoning are incredibly wrong.

If a woman has only sons, she is the first of her line going back to the beginning of the species to not have a daughter

re: Everyone alive today has had a living ancestor at every point in history
I do wonder about my ancestors back to the ancient times. My dad has tracked it back to the 1700s in certain aspects. But it would be awesome to like flip on a tv and check out anyone who is your ancestor at any moment in their life. I’m sure some have had some interesting experiences, life’s, deaths....

frick it. We need Assassins creed in real life

I think he is getting at the idea of huge ancient populations being wiped out because of ancient internet, social media, meteors, and volcanoes.

No, he's taking the total number of ancestors you have in your family tree and thinking they were all alive in the 1400s at the same time.

The 1400’s were called the dark ages for a reason.

The reformation was the first white flight.

I just realized that... every one of my ancestors is immortal.

You aren't accounting for the Alabama Grandpa-Daddy effect.

Your family tree might have that many leaves at the end of the branches but some of them might be the same person. Or maybe a grandmother on one side and a grandfather on the other side were cousins. In fact that wasn't uncommon at all "back in the day".
