[@leftylizard9085]

Not true. Charles II had 8 separate great grandparents. On his father's side he had Phillip II, Anne of Austria, Charles II, and Maria Anna of Bavaria (1551-1608). On his mother's side he had Phillip III, Margarita of Austria,. Ferdinand II, and Maria Anna of Bavaria, (1574-1616). That is 8 separate people. The only name that shows up twice is Maria Anna of Bavaria, and those were two different Maria Anna's of Bavaria since they were born in different years and died in different years. Phillip III may have been his grandfather on his father's side and his great-grandfather on his mother's side, but he still nevertheless did not have a great-grandparent on his mother's side who was also his great-grandparent on his father's side. So he still technically had 8 different great-grandparents. Some of those were also his grandparents, but he still did ultimately have eight great-grandparents in total.

So 7000 years ago, they are all my ancestors. But presumably, some of them (the ones that look like more like me) are my ancestors several hundred times over whereas some of them are my ancestor only once.

[@brcoutme]

Actually you left out the part where many of them are not related to you, its just that they are also not related to anyone else alive today. Otherwise, yeah you probably have more ways your related to some people than others (whom your related to) from 7,000 years ago. As they said though this modal is somewhat limited when referring to large populations where movement is restricted. For example we know that in Europe most people are related to Neanderthals with about 3% dna from them, while in Asia only 1%-2%, and in Africa almost none. That would imply that some amount of Europeans from only 7,000 are probably are not the ancestors of most of today Africans. Maybe I'm misunderstanding something (could be that dna reading technology is just too poor to identify these weak relationships like the one time connection you were mentioning).

[@fogease]

Kapil Kakodkar Biblical Mary

[@suokkos]

Too bad joke is incorrect. If you have larger population then virgin birth per person is less likely but you have much more birth events per generation balancing the probability. virgin birth per person is 1/n but to get probability for no virgin birth per generation you need to calculate (1-1/n)^n which would mean about 37% chance for no virgin birth in a large population.

[@SellymeYT]

​@@suokkos Your formula is right (assuming consistently sized generations), but your conclusion is a bit off. For positive integers, (1-1/n)^n starts at 0.25 (n=2, the smallest generation size for which this discussion is meaningful). As you say, the limit of f(n) is ~= a 36.7879% chance (1/e) of no virgin births in an arbitrarily large population. This means that population size increasing DOES slightly decrease the chances per generation (although in all cases it's still more likely than not).

[@suokkos]

@@SellymeYT , It does slightly decrees but clear decrees happens only for a few smallest and after that probability of no virgin birth is growing only very slightly with population size growth. So population size 6 is already close to same as population size of a million where both except to see no virgin birth approximately every 3rd year.

@Terry White While I'm not a citizen of the United Kingdom, I have looked into the studies of the costs of England's royal family vs. the costs of giving them back the property they've lent to the nation in exchange for their position and pay as well as the studies of how much they pull in in tourism money. They seem to be a net benefit to the UK, at least from a monetary point of view. They cost **much** less than they bring in to the government and the cost (in government property that would suddenly belong to the Windsor family instead) would be quite detrimental to a UK going through the own goal that is Brexit.

@Terry White Being condescending and ignorant is never an attractive trait either, yet you seem to be very fond of it.

Whenever I think about our most recent common ancestor, I just think about places like north sentinel island where they have not contacted any other people for thousands of years and basically how insane it is that we all were together at one point, and then some people left and apparently just forgot there were more of us

I don't think everyone is related to the von Habsburgs, their family tree is a family circle

Numberphile destroys the English Monarchy with FACTS and LOGIC!1! (Number 6 will have you shocked)

[@BlackfeatherTanfur]

Number 6, is that a Prisoner reference? If so, then who is the "New Number Two"?

[@paula194]

@@BlackfeatherTanfur To be honest, the choice of number was entirely arbitrary. The "Number 6 will have you shocked!" part is just part of me referencing clickbait list articles that would often have outrageous or garish titles like "6 ways you can solve all your problems (Number 2 will shock you!)" or "5 ways to know you're a genius (Number 3 is bonkers!). Continuing in the vein of clickbait titles, the initial part of my comment is referencing rather tasteless youtube videos that would have titles like "creationists (Though it could just as easily be Feminists, leftist, snowflakes, etc.) absolutely destroyed with Facts and Logic Though I am now curious what the "prisoner" you're talking about is

I'm directly related to Robert the Bruce! And actually, as a Canadian with very mixed heritage, I was surprised to find out that my 100% ethnically Norwegian maternal grandfather and my Scottish x Irish x French x Native North American maternal grandmother were each, within 8 generations back, ancestrally from the same farming community in Troms.

@@bunderbah Nahh man, I worked out how he does it. There seeps a special liquid out of his bottom and when people drink it they suddenly like him, fight for him (literally) and hate who ever he wants them to ;) Since it now has been proven that we're all related to each other, we can say that every single bad thing that has happened was done by a relative of Farage. Farages family did 9/11, Farages family killed Diana and the worst of all, Farages family said that Pluto wasn't a planet anymore.

This is by far the most awe inspiring video I've seen in quite some time. Just one remark though: if you apply the model to generations of, say, 1.000.000 people, it is true that virgin births become rarer, but you will still expect one per generation, so they will keep occurring.

Radio 4 More or Less concluded that by the time Jesus was born, every single child in Judea was descend from King David.

[@PeterJavi]

Thanks to king Salamon, it might only have been 5 or 6 generations

[@booksquid856]

Interesting. Guess that would mean the rabbis of that age were right in saying that anyone could be the long awaited “son of david.”

They mostly only considered the male line, though. Mary may have been an exception.
