In 2003 a groundbreaking historical genetics paper reported results which indicated that a substantial proportion of men in the world are direct line descendants of Genghis Khan.By direct line, I mean that they carry Y chromosomes which seem to have come down from an individual who lived approximately 1,000 years ago.This haplotype seems to have expanded relatively recently, as was evident from small number of mutational steps connecting all of the local variants.Figure 1 illustrates the phylogenetic network: The shaded area represents the star-phylogeny.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.As we do not exhibit the sexual dimorphism which is the norm in such organisms, it goes to show the plasticity of outcome due to the flexibility of human cultural forms.Jason Goldman of Thoughtful Animal reminded me of the 2003 paper a few days ago, so I thought it would be useful to review it again for new readers (as I know most of you have not been reading for 7 years! To understand how one Y chromosomal lineage can have such a wide distribution across such a large proportion of the human race, here is a quote attributed to Genghis Khan: The greatest joy for a man is to defeat his enemies, to drive them before him, to take from them all they possess, to see those they love in tears, to ride their horses, and to hold their wives and daughters in his arms.

Even with the demographic model most likely to lead to rapid increase of the lineage, double exponential growth, the probability was .In Muslim societies pride of place is given to Sayyids, descendants of Muhammad through his grandsons Hasan and Husain.Naturally this is often fictive, but that matters little.It’s characterized by a core haplotype, a nearby set of variants separated by one mutational step.This suggests that the genetic variant has risen rapidly in frequency before mutations had time to build up variation and generate a more complex topology.
