Modern men's genes suggest that something peculiar happened 5,000 to 7,000 years ago: Most of the male population across Asia, Europe and Africa seems to have died off, leaving behind just one man for every 17 women.
This so-called population "bottleneck" was first proposed in 2015, and since then, researchers have been trying to figure out what could've caused it. One hypothesis held that the drop-off in the male population occurred due to ecological or climatic factors that mainly affected male offspring, while another idea suggested that the die-off happened because some males had more power in society, and thus produced more children.
Now, a new paper, published May 25 in the journal Nature Communications, offers yet another explanation: People living in patrilineal clans (consisting of males from the same descent) might have fought with each other, wiping out entire male lineages at a time.
That ratio of 17 females for every one male "struck us as being very extreme, and there must be another explanation," said senior study author Marcus Feldman, a population geneticist at Stanford University in California. According to their new explanation, the male population didn't take a nosedive, but rather the diversity of the Y chromosome decreased due to the way people lived and fought with each other. In other words, there weren't actually fewer males, just less diversity among the males.

You might be onto something. The Hun had a habit of killing all the men and boys. It cut down on all of the “revenge” hormones causing trouble.
It was a lot easier to hold onto territory in the rear when the possibility of revolt was minimized.
Anthropologists say that the entire world’s human population was down to just 10,000 people several hundred thousand years ago. We came that close to being extinct.

Those estimates have their origins here and have been lessened a bit lately.

As a post script, I guess the moral is, screw them all while you get the chance because this might be your last season..........LOL!
