Another theory about the lack of genetic diversity called the Neolithic Y chromosome bottleneck. It is just a theory that tries to explain the lack of diversity in the Y chromosome which is passed on to male children during breeding/fertilization of the egg. This new theory which was published in the science journal "Nature" puts forward a rather brutal proposal of a world wide society gone into testosterone overload.

I have read over the years all kinds of estimates of how close our particular species came to going extinct and in truth this article is more generous with the estimated breeding pairs remaining than many other articles I have read..

Obviously early man was close to nature and observed other animal's behavior as far as who gets to breed so it could be as simple as the big guy gets the girls (think Harem) and the lessor men get the sheep or whatever ?

A more modern day example would be Genghis Khan as he certainly comes to mind as one of the most prolific breeders of all time. Supposedly one in every 200 men carry the great Khan's Y chromosome.. But new findings say there were 10 other contenders for that trophy... Maybe contenders but even Giocangga of the Qinq Dynasty comes in as a distant second place to the great Khan.. Maybe that is why he is referred to as the great Khan; possibly a rumor spread by the women folk ? That is intended as a joke for those without a sense of humor haha

I thought it might be interesting to hear what some of you think about the Y chromosome bottleneck and the reasons you believe it came about..


It’s a point in our stone-age past when our genetic diversity suddenly choked. At least among the male-transmitted genes. After a period of some 2,000 years of decline, there was only one fertile male left alive to mate with every 17 women.



It was a time when the world population is estimated to have been somewhere between five and 20 million people. To leave such a stark genetic imprint behind, as many as 9.5 million men must have been killed.


Or simply not allowed to breed ...

This event seems to have happened worldwide. If one group of men had developed skills like stone wall building and agriculture that would be enough to attract women who would want a safe place to have children. Maybe it simply improved the survival chances of those children through childhood diseases.

I think there is some truth to this, and can be seen in the declining birth rate of modern man.

A species reach's a certain point and that's all she wrote.

But what do i know.

I don't think it's very simple. Let's take geological and astronomical events.


Somewhere around 9700bce we had a massive cme event the entire world witnessed and the civilizations retracted enormously. Fire reined down from the sky and the radiation probably killed off massive populations. Only people in caves survived most likely.

So what does that mean?

Very small pools left and society starts from scratch.

So the CME only killed males? Not likely

No we probably don't understand what happened to the DNA and the mating with cousins phenom.

I think perhaps, beyond royal breeding rights, natural calamities having more severe effects within some geographical areas than others, could explain this just as readily. Famine etc.. turning once lush vibrant areas into less than hospitable, sending people off in search of protein and falling under aforementioned other rulers rule...plays heavily into this.

it wasnt a cme, cmes dont kill, it was theoretically a comet.

Interesting item...I'll follow its progress. Makes me think of the so-called Huron and Iroquois disputes that resulted in the 'dispersal' of the Huron.

A massive cme would certainly kill. There is no evidence of comet, while there is evidence of lightening. Like mass amounts of lightning.

Personally I think Anthony peratts work and goblieki tempe are a pretty good indication something went wrong and there was a civilization back then. Could it be a comet sure. But a a massive cme would create lightning like rain and massive radiation the ozone layer would be severely destroyed. This is starting to be uncovered in ice core samples.


It would also explain why this is found all over.

They had "African" Lions up in Europe back in those days. And how they do it is one male maintains the pride. The rest are barely a peanut gallery.

probably has more to due with the cataclysm caused by comet or solar flare

Sorry, reads like a lot of poppycock and supposition.

Probably some natural disaster that may have affected a certain area, but all the Worlds Male population?

Once again, the experts forget about humans like the Australian Peoples, who have lived relatively the same for 100,000 years. Had art work and rock art around the same time as those found in Europe and Africa.
Not to mention, if there was such a calamity, why are their still Marsupials and Monotremes in Australia?

Not doubting there was some sort of natural event to cause a culling, but humans survived the Ice age, indeed even as recent as 15,000 years ago, the Worlds oceans were much lower than today......so the experts tell us.

Perhaps many died as the Ocean levels increased, with low lying communities and their food sources affected?.

Weren't the Native Peoples of North and South America already there 15,000 or so years ago? Did they miss out on this "Euro/African/West Asia" Calamity?

Its only "expert" guessing, again.

We have been finding more and more fossil records and artifact to show we don't have a clue.

Oh we can't find any tools they must not have them.

Pretty sure they won't find hammers at the empire state building either. When they dated Gobleiki Tempe things should have changed in the minds of scholars but many already have their careers resting on the books they wrote.

I don't think we have had a linear progression. Natural disaster pushed people back to start over.

Look at Egypt.. it used to be a quack theory the sphinx was older than 2500 bc. Now it's being accepted the head was recarved and the pyramids are on older mounds.

You have the early three and then they can't reproduce the same quality...

We probably need a more open mind as to what happened. We keep getting pushed put of Africa earlier and earlier. Now even early hominids were using hunting weapons.

Here is a counter argument more modern and accounts for the lack of impact crater.

EVIDENCE FOR A SOLAR FLARE CAUSE OF THE PLEISTOCENE MASS
EXTINCTION
Paul A LaViolette
The Starburst Foundation, 1176 Hedgewood Lane, Niskayuna, New York 12309, USA. Email: starburstfound@aol.com.
ABSTRACT. The hypothesis is presented that an abrupt rise in atmospheric radiocarbon concentration evident in the Cariaco
Basin varve record at 12,837 ± 10 cal yr BP, contemporaneous with the Rancholabrean termination, may have been produced
by a super-sized solar proton event (SPE) having a fluence of ~1.3 × 1011 protons/cm2. A SPE of this magnitude would have
been large enough to deliver a lethal radiation dose of at least 3–6 Sv to the Earth’s surface, and hence could have been a prin-
cipal cause of the final termination of the Pleistocene megafauna and several genera of smaller mammals and birds. The event
time-correlates with a large-magnitude acidity spike found at 1708.65 m in the GISP2 Greenland ice record, which is associ-
ated with high NO–3 ion concentrations and a rapid rise in 10Be deposition rate, all of which are indicators of a sudden cosmic-
ray influx. The depletion of nitrate ions within this acidic ice layer suggests that the snowpack surface at that time was
exposed to intense UV for a prolonged period, which is consistent with a temporary destruction of the polar ozone layer by
solar cosmic rays. The acidity event also coincides with a large-magnitude, abrupt climatic excursion and is associated with
elevated ammonium ion concentrations, an indicator of global fires.

It does not have to be just a solar flare or a comet.. It could be both over a given time frame.. The comet is pretty well proven in many people's minds due to the spread of nano diamonds and other spheroids found over a huge area of the earth.. Best guess is the impact was in Canada on top of a huge ice sheet..

Interesting about the solar flare I will look into that more when I have the time..

On a topical note: Something darn sure happened to cause the bottleneck.. Was it a societal thingy or an almost earth wide natural disaster ? Maybe both ?

So no lack of testosterone now at all , it was just overload back then resulting in Men killing men , actually we need even less testosterone right. Maybe we need some chip that is balancing the hormonal levels ? giving man less testosteron and women more. Maybe even get rid of gender and identity altogether ?

I dunno. Disease could certainly have done this, along with famine and other causes. I don't see a global war as a cause - we'd see more burials where people met with violence.

Climate change and decline of resources (it's about the end of the Great Extinction) along with the First Founder scheme could have done it.

So... let's say that there wasn't a war, but there was a time when fewer male babies survived birth and childhood. A few generations of this would cause a collapse of the Y chromosome lineages.

By the wholesale drop of sperm counts across the world that might not be a good idea. No chip necessary as something is happening already.. Probably drugs in the water would be my first guess followed by the food some eat?

Around here, where I presently live, women with allot of testosterone are called Toms and like and live with girls or women.. Not much for the breeding and continuation of the human race IMO.
