Evidence for “Selfish Genes”?

I am reading Deepak Lal’s In Praise of Empires: Globalization and Order at the moment. In a discussion of the Mongolian empire, initiated by Genghis Khan, Lal tells the well-known and terrifying anecdote about Genghis Khan’s reaction when told by his generals that life’s sweetest pleasure lies in falconry:
“You are mistaken. Man’s greatest good fortune is to chase and defeat his enemy, seize his total possession, leave his married women weeping and wailing, ride his gelding, and use the bodies of his women as a nightshirt and support.”
Lal goes on to observe that
“This pursuit of booty along with glory also succeeded in a massive spread of Genghis’s genes, as has been recently confirmed in a study examining the chromosomes of 2,123 men from across Asia. It found that an estimated 16 million males in a vast swath from Manchuria to Uzbekistan and Afghanistan are the direct descendants of Genghis as they carry his unique bits of DNA in their chromosomes. Genghis’s fighting thus allowed him to propagate his selfish genes to an unparalleled extent” (p.16).
(The study that Lal cites is this paper, which notes that in the examined sample, 8 percent of the men had virtually identical Y chromosomes, which indicates a common forefather. The 23 authors argue that this forefather is very likely to have lived in Mongolia and to have been Ghengis Khan).
In contrast to the Khan, Hitler, Stalin, and Kim-the-Older were no great gene disseminators, while Mao apparently was and Kim-the-younger apparently is (cf. this blog).

This brings to mind the saga of accounting professor Tom Robinson, who turns out not be one of Khan’s descendants after all:
