1. this is amazing
2. yay im Somali my countrywas on the map im gunna cherish this for ever
3. Interesting, but there is one aspect that would allow to drive the number of ancestors to a somewhat higher value and that is because; if you look at certain n-th generation of ancestors they might not have lived in a certain fixed time period (say in the year 1500) but there is some longer span of time that this whole n-th generation lived in allowing more people to interact and the further you go in the past that time span would just become bigger - although the number of ancestor will still be limited and smaller than 2 to the power of (n+1) minus 1.
4. Has there been made an approximation to how many ancestors we have since the primordial soup?
5. To some of the comments below: Some of my anchestors (as of anybodies, but for me it is near enough to know some of them personally) are "aristocrats". They spoke of "Ahnenschwund" wich is literally "loss of ancestors" - instead of using the word "incest". By the way: It is no incest if the relationship is "xth cousin once removed". But for them it was totally impossible to ignore the fact, because their roots are common knowledge (or at least easy to be found).
   
   So what you said was common knowledge for me - but I never before saw it put as easily together as in this clip. Thx!

7. Fascinating! Great video. TY
8. so I guess i'm selfish for not having any children so that means i'm putting a end to the billions of peoples birth line..it's sad to think i'm doing what millions of years of life have allowed me to be born
9. All I know is that everyone reading this needs to put me in their will.
10. I'd be interested to know how many unique ancestors I have, not just going back to the neolithic revolution, but back to the very first primordial amoeba that could be considered to be alive. Obviously no one's ever going to come up with an answer that could be considered remotely accurate, but has anyone ever even attempted to ballbark it, even to within a few orders of magnitude? I'd be really interested to know.
11. Amazing video.
12. EXCELLENT video. Have been telling this to people for years! Michael J Fox, when he went back to the Future past, would have had to meet like 1,000 grandparents, not two! Go back 2,000 years you'd have more grandparents than people on earth. It's crazy! We are all a result of incest??! Whey did they give Jerry Lee Lewis such a hard time had he only known he could have used this argument!
13. Awesome!!!
14. Great channel, and great video! So what's the probability of bumping into someone on Earth that you're not related to?
15. good job keep it up mate
16. i love you and your channel and thank you
17. I couldn't have said it better nephew.
18. Excellent video ! Thanks
    
    When I started my genealogy, I was wondering how many generations from me it would take to find a first marriage between cousins. Did not took long, in 1839 I have an ancestor who married his third cousin. But as you said, when you have a branch of a family who remained for more than 300 years in the same village, what do you expect. 
    
    I also had an ancestor who had an written permission from the Vatican ( through a priest ) to marry a cousin of his. It was accepted and the reason given was that the parish was so small that at some point people had to marry cousins, more or less close. 
19. Respect to the amount of research you've done to make such a great video! I do love learning new things in the morning :)
20. love the use of 2048 as a visual aid!
