Heirs of Genghis: where are they now?

The Giray family are a royal family descended from Genghis Khan, they use to be Khans of Crimea and other breakaway Khanates from the Golden Horde.

The current head of the family owns a design firm, not likely to rule the world but still good

Share your interesting "where are they now" stories of descendants of Genghis Khan here!!

[Subedei]

Wow, interesting subject. How did you find out about that guy????

[Craterus]

Genghis Kahn slept with so many women, it is estimated that one in two hundred males are direct descendants.

Genghis Kahn slept with so many women, it is estimated that one in two hundred males are direct descendants.

to maintain the same population size over generations, each couple must get 2 surviving offspring at the very least on average, which results in a branching factor of 2 per generation. The result is that in about 10 generations, about 2 to the power of 10 people will be "distant relatives" of yours. So you could say the same for almost any man who lived way back in the Medieval period, and even more so about men who lived even further back. If you don't account for population increase and assume all people can choose their partner randomly from all over the world during the entire period of some 1000 years, and they choose their partners among people who aren't relatives of theirs during those 1000 years, you get 2 to the power of 30, which is 10 billion, people who would be distantly related to the average male of year 1000. In reality it's more complex, as you need to take into account limited mixing, non-random partner choices and population increase over time, people not mixing between classes (but children outside marriage was common so the point has limited impact), and people who are distantly related forming couples, but the conclusion is quite interesting - most people are distantly related to most Medieval persons.

I read a research report that says that Genghis Khan could be responsible for at least 0.5% of the world's male population or something like that.

Plus, i read wikipedia to find out about the Giray family. Very interesting. The branch in London took an interesting turn when one of its ancestors converted from Islam to Protestantism and married a Scottish lady of high lineage or something.

It's estimated that 83% of the Europeans descend from Charlemagne.

All right, I made up the 83% because I couldn't remember the exact stats, but it was a significant majority.

[Rodion Romanovich]

well again, probably about 83% in Europe descend from Jean-Pierre the peasant too I'd like to see any scientists doing a more serious calculation model than I made above, to see their estimate of how many "distant descendants" the average Medieval man of around 1000 AD would have by now, but I'm sure it can't be far below the values of Ghenghis and Charlemagne. I might as well ask - has anyone seen a study about the very subject? If there have been studies about how many descendants people like Genghis and Charlemagne have, it wouldn't be too off having a similar study for the average male.

There's been a number of genetic studies which trace the dissemination of genetic markers (a good reflection of the actual inheritance from an individual). Ghengis Khan is a prime suspect for a big genetic inheritance pattern:

Y Chromosome evidence


General historical figures (I loathe Wikipedia for serious stuff, but my sources otherwise are books and papers, and at least this article gives references for a change).

Newsy type coverage

Ghengis has a big genetic footprint (at least theoretically) as with other powerful figures because they would have had a much greater chance of breeding children than Jean-Pierre the peasant. These children would have been, in their turn, much more successful in breeding and so the genes traceable to that individual would dominate in a population.

[Subedei]

Interesting statistics around here, respect....didn`t know a lot about these "quantitive theories"....So what you say is "There is a little bit of Genghis in [pretty close to] all of us!"....

Well, since there are more lower-class than upper class, eventually after a few generations many children of Genghis or similar would be lower-class, and lose that better chance of reproduction. Also, Genghis is a bit of an exception for an otherwise common rule - that upper class people refuse to mix with lower class people. Since the upper class is smaller, if the upper class is fairly constant, the upper class would essentially mostly mix with other upper class and only occasionally (through new rich and through occasional secret love affairs with lower class people) get descendants within the lower classes (plus such secret lovers would surely after 1 generation lose any monetary support they ever had from the upper class partner). Indeed, many European ruling lineages were heavily inbred between Habsburg era and the early 20th century, including for instance the Romanov tsar lineage.

That's interesting, but a bit strange way of going about the problem IMO. It's an irreversible function, i.e. different persons could have contributed to modern people with the same genes, so if you find a certain gene it's impossible to tell whether it was from Genghis or someone else. However, since the evolution model is well established, it's possible to do the reversal, by using mathematical graph theory you should be able to calculate the number of descendants from a certain person, and using even more complex models be able to tell how large percentage of the DNA they are likely to have contributed to in modern day people etc. Such mathematical studies would also be useful for finding answers to questions such as: "is avoidance of inbreeding with 3rd, 4th or later generation relatives an important element in partner choice behaviors?", "do we seek our opposites or our likes?" and finding out the importance of actually contributing genetically to the next generation compared to letting a brother do it - is there are all any difference noticeable after 10 generations? After 100? Or will the effect oppositely multiply itself over generations? It could also be used to estimate whether behaviors to compete for sex are more important than good survival behaviors (by comparing with chances of genetically dying from bad survival genes compared to chances of genetically dying from bad sexual-competition genes), which would be very useful for analyzing human behavior. If reproduction-competition is more important than being a good survivor, for instance, then it would have huge consequences to what behaviors are most likely in human nature - warlike instincts (common chimp) or peace and love (bonobo)? I'll take some time and formulate a few models, but from what I've heard there have already been various studies of mathematical graph theory related to inheritance and similar.

For a good introduction to genetic influences on behaviour read 'The Selfish Gene' by Richard Dawkins, and anything on the Evolutionary Stable Strategy formulated by Maynard Smith.

Thanks, I might check it out

Its much easier to trace female inheritance patterns, since mitochondrial DNA is inherited only from the mother and mutates at a predictable rate. A study couldn't be done as easily on a man, y chromosomes are much more finicky.

I think they are on some British Cell Phone ad.
Really I bet they are everywhere

[kataphraktoi]

A piece of greatness huh

So do I follow his example if I wanted to create my own nation too? hmmm I smell a new thread in the frontroom.

[The Stranger]

yeah thats right

[The Wizard]

I seem to remember he had around twenty million descendants smeared out over the Eurasian steppes. That's a bigger family than there are people in the Netherlands

[kataphraktoi]

well in today's corporate world, GK is productive isn't he?

"lift your workrate!"

"we need better return on investment"

ineresting word "smeared", a fitting description
