Eleven fathers of Asia : 800 million modern men descended from ancient leaders - including Genghis Khan

curieusement ça ne concerne pas les femmes

Similarly, a maternal tree can be generated by looking at mitochondrial DNA, which is passed down solely from mothers to their children. However, when looking at this maternal tree, there is no similar explosion. This indicates that whatever factors were responsible for this pattern were specific to men. As the Y chromosome itself contains few genes that could give one man an evolutionary advantage over another, the explanations for this must be a mixture of chance and the cultural factors passed down alongside the genes.

mais ils n’expliquent pas pourquoi

Sûrement un effet de bord du #patriarcat. Je ne sais pas à quel point c’est l’expansion des peuples vainqueurs qui a donné cette proportion de paternalité, ou si c’est la #culture_du_viol sur les femmes des peuples perdants.

The 11 fathers of Asia: 800 million modern men are descended from a handful of ancient leaders - including Genghis Khan

Scientists from the University of Leicester traced DNA in modern men to ’founding fathers’ that lived across Asia between 1300BC and 1100AD
The geneticists traced each the eleven lineages back to their potential roots in the Middle East, India, China, Mongolia and south east Asia
They analysed Y chromosomes from 5,000 men from 127 populations
16 million men are thought to be directly descended from Genghis Khan
1.5 million are descended from 14th Century Chinese leader Giocangga

Genghis Khan died ~750 years ago, so assuming 25 years per generation, you get about 30 men between the present and that period. In more quantitative terms, ~10% of the men who reside within the borders of the Mongol Empire as it was at the death of Genghis Khan may carry his Y chromosome, and so ~0.5% of men in the world, about 16 million individuals alive today, do so. Since 2003 there have been other cases of “super-Y” lineages. For example the Manchu lineage and the Uí Néill lineage
