      If you're 8,527th in line to the throne, it shouldn't matter if someone further down the line dies. Your position in the line of succession remains the same. It only changes if someone higher up the totem pole than you dies, in which case, you get bumped up a spot to 8,526th.

      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.

      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).

      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
      @SellymeYT Před 5 lety +1

      ​@@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
      @suokkos Před 5 lety

      @@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.

      Except that the Aboriginals and Native Americans of today likely share ancestry with people from other continents. Considering that the Americas were discovered in 1492 and Australia was discovered in 1770, there's been a lot of time for ancestral lines to mix. It wouldn't even have to be much: just a single ancestor from another continent would make them directly descended from the most recent common ancestor.

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.
