Why Do Genes Suggest Most Men Died Off 7,000 Years Ago?
Live Science ^ | June 6, 2018 | Yasemin Saplakoglu

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.

Rudyard Kipling (1865-1936)
The Female of the Species

WHEN the Himalayan peasant meets the he-bear in his pride,
He shouts to scare the monster, who will often turn aside.
But the she-bear thus accosted rends the peasant tooth and nail.
For the female of the species is more deadly than the male.

When Nag the basking cobra hears the careless foot of man,
He will sometimes wriggle sideways and avoid it if he can.
But his mate makes no such motion where she camps beside the trail.
For the female of the species is more deadly than the male.

When the early Jesuit fathers preached to Hurons and Choctaws,
They prayed to be delivered from the vengeance of the squaws.
‘Twas the women, not the warriors, turned those stark enthusiasts pale.
For the female of the species is more deadly than the male.

Man’s timid heart is bursting with the things he must not say,
For the Woman that God gave him isn’t his to give away;
But when hunter meets with husbands, each confirms the other’s tale—
The female of the species is more deadly than the male.

Man, a bear in most relations—worm and savage otherwise,—
Man propounds negotiations, Man accepts the compromise.
Very rarely will he squarely push the logic of a fact
To its ultimate conclusion in unmitigated act.

Fear, or foolishness, impels him, ere he lay the wicked low,
To concede some form of trial even to his fiercest foe.
Mirth obscene diverts his anger—Doubt and Pity oft perplex
Him in dealing with an issue—to the scandal of The Sex!

But the Woman that God gave him, every fibre of her frame
Proves her launched for one sole issue, armed and engined for the same;
And to serve that single issue, lest the generations fail,
The female of the species must be deadlier than the male.

She who faces Death by torture for each life beneath her breast
May not deal in doubt or pity—must not swerve for fact or jest.
These be purely male diversions—not in these her honour dwells—
She the Other Law we live by, is that Law and nothing else.

She can bring no more to living than the powers that make her great
As the Mother of the Infant and the Mistress of the Mate.
And when Babe and Man are lacking and she strides unclaimed to claim
Her right as femme (and baron), her equipment is the same.

She is wedded to convictions—in default of grosser ties;
Her contentions are her children, Heaven help him who denies!—
He will meet no suave discussion, but the instant, white-hot, wild,
Wakened female of the species warring as for spouse and child.

Unprovoked and awful charges—even so the she-bear fights,
Speech that drips, corrodes, and poisons—even so the cobra bites,
Scientific vivisection of one nerve till it is raw
And the victim writhes in anguish—like the Jesuit with the squaw!

So it comes that Man, the coward, when he gathers to confer
With his fellow-braves in council, dare not leave a place for her
Where, at war with Life and Conscience, he uplifts his erring hands
To some God of Abstract Justice—which no woman understands.

And Man knows it! Knows, moreover, that the Woman that God gave him
Must command but may not govern—shall enthral but not enslave him.
And She knows, because She warns him, and Her instincts never fail,
That the Female of Her Species is more deadly than the Male

This has to do with larger family sizes due to the rather sudden shift to agriculture

I agree. I also suspect that it was not just larger family sizes but also more desirable mates outside of the family. If you are a hunter-gather and are marring off your daughters, do you want them to go to another clan of hunter-gathers that are barely getting by, or to the well-fed farm family in the valley with a bunch of sons?

5000 years ago would be about the time the great flood is thought have occurred.
So Noah and his family would have represented the gene pool.

I’ve never heard of biblical data making that precise a date for the flood.
There is a gap in the genealogies that is post flood. And last I heard, that gap had been narrowed to about 500 years.

5 to 7000 ya was the neolithic period notable for violent deaths and tribal warfare. I’m guessing only those families with the most male children survived to reproduce. They would all have the same Y gene.

In the evolutionary scheme of things, men are utterly disposable. One man can boink thousands of women

A co-worker married an African woman and they paid a visit to his Father in Law who lived on the eastern coast - I forget the country.

He kept 3 wives in 3 different apartments. I guess this was a status symbol.

My co-worker friend related that the only thing he observed was that having 3 wives made his FIL at least 30 times as hen-pecked.

We are headed to that situation where males don’t procreate because they are queer or kicked in the gonads by butch feminists. Researchers will have an orgy analyzing that phenomenon.

Just my thinking. Most of the 16 out of 17 males also live in their mother’s basement.

Added to that is maybe this:

War in the ancient times was an all male activity with rare exceptions. Wiping out all the males in an AO, or reducing surviving males to slave status was fairly common, iirc. And females all went to the victors.

I suspect that the world was awash in small scale wars back then. Village against village, region against region, and such like. And the wandering hunter/gatherer purist clans that refused to make the transition to settled agri life working as raiders on those settled villages.

So, imo, it was probably a whole host of stuff that added up to what we see in the gene record.

In other words, there weren’t actually fewer males, just less diversity among the males.

In simple words, “The winners got the women and left their DNA for the centuries to follow!”

The losers got what was leftover.

Lots of wars before agriculture.

Just smallers scale.

Lots of tribes wiped out other tribes, killed the men and kept the women and children.

I’ll go with strong men with lots of wives. They killed off the weaker men

Harems are the visible evidence of the ancient practice.
