You DON’T Descend From All Your Ancestors

Seems to me that it would be more correct to say we don't inherit genetic material from all our ancestors, but we certainly descend from all of them.

This video doesn't descend from all of my youtube video history, but here it is

One correction:

If you have living descendants in 400 years, you only have a 3% chance of contributing to the genetic makeup OF ANY SINGLE descendant. If you have at least a few tens of descendants, chances are good that you contributed something to their genetics

Sometimes the youtube algorithm just recommends you an actually interesting and educational video.

My ancestor of 15 generations ago might not have given me any genes but had this person not lived or not had any children I wouldn't have existed.

I need this, pixel style, retro music, video essay format with knowledge you never thought about until you clicked on this video, and a narrator with a soothing and calming voice that is able to easily explain these concepts it’s too perfect. Give me 500 more of these

DNA passing down through your lineage is like the longest game of “Telephone” ever. Message is barely distorted from one person to the next, but those distortions build enough to change the message considerably the further you move from the “initial” messenger.

Just wanted to say that this video prompted me to go and read David Reich's book. It's amazing. It clearly explains the ideas of the statistical methods used, without getting lost in the details, and covers the state-of-the-art conclusions that we can draw from them. Unlike a lot of pop-science it doesn't speak down to the reader, and it fully expects you to pay attention while reading - it rarely repeats itself. The result is a book that's fascinating and educational; I could hardly recommend it enough to someone who wants to know the science behind the headlines of ancient population migrations.

How did i just stumble apon the most interesting youtube video ever, and it only has 63 views? great work bro love this style.

The problem with choosing King Charles III is that we know how noble families did favor inbreeding in a higher level than the common folk. He may have inherited some genes from a 15th generation ancestor from different branches of the European noble family.

You may not contribute anything genetically to a descendant, given enough time, but they are still a descendant. & they still wouldn't exist if you hadn't existed as an ancestor. Pretty amazing really.

WHAT A SPLENDID VIDEO. I really found myself digging into the topic of ancestry the last couple of years. Discovering my "older" family roots. This video puts a lot of things into perspective. If you are unsure where your family or you are from, do not worry! After a couple hundred years it pretty much does not matter anymore :)

Trippy 8-bit console science vibe I love it.

[posysdogovych]

This simultaneously manages to be an extremely informative scientific video and a tribute to old school Nintendo music and graphics.

[blue_bach]

“…one might imagine it’s irrelevant how many theoretical ancestors a person had 32 generations ago. Due to cousin marriage…” You know I was not imagining that at all actually but it’s a fair point.

[mattrommel]

Love how many seconds a genetics video spent roasting Prince Edward lol

[jamesfetherston]

In King Charles case, Queen Victoria likely had more contribution as she was an ancestor of both of his parents.

Does this mean that if I took a time machine and met my 15x great grandfather (a man who was requisite in my existence), we are literally not blood related? That is a MINDBLOWING concept.

The thing is: Charles descents a whooping 2244 times from Casimir IV Jagiellon!, so that makes it pretty much certain that the latter contributed to his DNA, ofc nobility is an extreme example of in-breeding, but courtesy of phenomena like the Founder Effect and the simple fact that people in pre modern times tended to live all their lives in their small closed communities and mostly met with people who they were related to some degree, most people would be shocked at how many times the same individual can appear in a person's family tree, even the average folk.

Despite that, your model might be close to what we will see in the future as centuries of the new urban dynamics go by, so your prediction is probably still spot on. Great content, man, glad this video exploded the visuals are just great.

I was sort of following up until 5.30 but then the sheer magnitude of numbers fried my brain.
