Back in the previous 1990s , a team of external geneticist research the genetic history of a bit of Asian population stumbled across a very strange Y - chromosome mutation . They found that it occur in about 8 percent of the male person in 16 of the populations — a jolly large part , as far asgenetic mutationsgo . Upon further investigation , the squad reckon that the most recent mutual ancestor of the mutate grouping survive about 1,000 years ago .
That 8 percent converts into 0.5 percent of the manful universe of the world , which made this unknown man the lineal ancestor of about 16 million men around the globe [ beginning : Zerjal ] . That ’s a whole lot of descendant to gather over a relatively myopic period . So the geneticist knew the phenomenon was due to more than justnatural selectionor biologic vantage . It was more likely transmitted through a very rare happening of societal selection : Somehow , the male person in the lineage had attained increased reproductivity , and unrelated Male had been at least part rule out .
As it turn out , the 16 population were in countries ( China , Mongolia , Uzbekistan , Kazakhstan , Russia , Afghanistan , Pakistan , Iran and Iraq ) that had been part of the Mongol Empire , the territory of Genghis Khan . The highest concentration was in Mongolia itself , and there was also a tribe in Pakistan with high-pitched oftenness of the mutation . This clan happens to have a long account of exact to be straight off come down fromGenghis Khan . So all arrows started to orient to the notoriously vicious empire - builder as the culprit of this social hullabaloo .
Genghis Khan was n’t the first man to have this mutation — it in all probability bulge out with one of his with child - great - grandfathers — but he sure enough set the bicycle in motility for its speedy spread . The Mongols are still infamous for their pillage - and - plunder tactics , routinely mow down the valet de chambre in the populations they conquered . ( Elimination of unrelated males ? fit . ) They also adopt the women for their own , making them doxy or collect them into hareem . The direct Khan descendants got their plectrum of the woman and tend to have overpowering total of small fry . Khan ’s son Tushi was said to have had 40 boy . ( Increased reproductivity ? Check . ) This pattern continue for one C of years — it was , the researchers said , " natural selection based on societal prestige " [ source : Zerjal ] .
The only way to definitively sustain this theory is to perform DNA testing on Genghis Khan ’s remains , which is most likely never going to fall out , but the geneticist do make a good guinea pig that Genghis Khan is the unmediated antecedent of .5 percent of the populace ’s male population .
But wait … it ’s just the men we ’re talking about here . The Y - chromosome is passed like a shot from father to son ( it ’s the only part of the genome that does n’t combine with the mother ’s cistron ) , so it ’s the easiest and best way to get across agnate lineage . There is no Y - chromosome equivalent that allow similar documentation of maternal lineage , so there ’s no way of know precisely how many women are also part of the Khan clan . regretful , dame .
