What I always wondered was how did they manage to work out they could make fire with friction and/or flints. I mean, if I already didn't know how, I might try with a magnifying glass but it would never occur to me to try it with friction. IQ would have a lot to do with it.

It is one of the reasons why humanity is so uniform, both in morphology and in behaviour. Without this event, there would be much more variations in body shape, intellect, etc.
@@mutteringmale In humans there's a severe problem in having a too closely related DNA which causes morphology and behavior, makes it more often that recessive diseases and deformities appear.
There it is, the big lie the churches, who control all your normal bodily function and makes you pay for it, has told you. The genetic diversity is only really applicable in small populations, very small. Bad genes then get passed around and there is a TINY bit of malformed genetic code.

0:07 The picture shows a population bottleneck, not a genetic bottleneck. In a population bottleneck, all populations survive and reproduce, just in fewer numbers. In a genetic bottleneck, genetic diversity has been reduced, usually from the extinction of one or more genetically distinct populations within the species.
@@billcrandall9386 A population bottleneck is just a large reduction in the overall number of individuals in a species, while still keeping its genetic diversity. A genetic bottleneck is an elimination of several populations within the species, greatly reducing the species' genetic diversity. Of course, they can both occur at the same time.
This comment will probably get lost, but can you cite your sources? This kind of thing is exactly what I'm into but I feel uncomfortable watching this without the sources to back it up.
The time frames that so many of these things reference is just mind blowing. When hundreds of thousands of years seem like one of the shorter time frames. it's just crazy how long some of this stuff took.
You miss one hypothesis: That they kill each others to almost extinction... and that we are the heirs of the worst of the worse. The ones who survived.
we would not be living close. our ancient ancestors lived in small family tribes. and would live pretty far from any other tribe. because hunting and gathering requires you to cover huge piece of land to get enough food.... but yea, if you were living close to some other tribe, you would no be very friendly with them because you are competing for same resources. they would probably get into frequent raids. stealing food and women.
That just means we have a whole 8 in a billion individuals, or we have 8,000 one in a million people, or 8,000,000 one in a thousand people, or 800,000,000 one in ten people.
I remember reading that this event is also suspected to have been caused by something cosmic. Like, a meteor impact or a powerful ray burst. A lot of species went extinct during this event. One interesting thing that those species who survived had in common was that they tended to live at least part-time in caves.
You are mixing up millions of years apart extinction events. The meteor extinction phase saw our rodent-like tiny ancestors hiding in burrows at that time, in a reptilian world.
Imagine being the cavebro whose family had won the cave real estate by combat, you wake up one more morning and all your outside homies are blackened skeletons.

We now know that Toba was more locally devastating than globally. While certain areas of humans nearly went extinct in many other places they were doing just fine.
75,000 year ago Mt. Toba exploded wiping out many humans, animals and plants. If there was a highly advanced human civilization say Ramachandra was more advanced that we will be in 200 years failed to stop the caldera. I would say it was a centuries long civil war that took more time and tech to maintain instead of ending it. Why they were caught with their pants down when it exploded. damaged it severely and 42,000 years ago was the final end to it.
There'd be so much more proselytizing nowadays if the Velocopastors didn't go extinct. Some say it was the ice, others say it was the lack of donations.
@@iGame3Dthey all died off due to multiple factors one of them being the homo sapien being the smartest of the other hominid species so they possibly killed them
The 'Volume of Material Erupted' graphic at 0:39 is wrong, on the date of the Yellowstone Huckleberry Ridge eruption. That was 2.1 million years ago, not 74000. If it was 74000, that would put it roughly concurrent with the Toba eruption - which would definitely help to bolster the Toba bottleneck theory...if it were a correct dating...which it's not.

Yea, what he says is wrong. It had the same outcome, as the ice sheets grew migration was easier, but not over land, it was over the ice. Please turn your flag around.
@@bigredc222 Actually there was a lot more land on the seacoast, the ice on the continents lowered the sea levels, ice in the water will raise them slightly as water expands when it forms ice, and yes as the weight depressed the land under the glaciers, other ice free areas would have risen. Ice melting at the North Pole will not make that much difference to the Sea levels, ice melting in Antarctica and Greenland is what will sink Miami. Climate change is a fact and whether it happens naturally or we speed it up, it is real and doesn't give a damn if you believe in it or not. The only reasonable argument to be made is not whether it is happening, but how are we going to adapt to it in order to survive as a viable civilization.

The population was too tiny and spread out, so groups would be unlikely to come into contact with each other to spread such a disease, particularly a fatal one that killed the whole band. Pandemics only become a thing when you have a denser population where the organism can spread easily. Most of our worst infectious diseases appeared when we started living in close quarters in towns and cities.

Chicken Pox is a herpes virus. Anthrax has been found surviving in dried soil that was stored for 60 years.
Doubt it. Clusters of population were quite separated--occasional contact with other clusters, but bounded within available food regions. Fire was used for cooking and protection longer than a million years ago. But early migrations likely failed for many reasons.
Just scrolling, saw the title, had to comment. There were NO humans on Earth 900,000 years ago! Not even "early humans!" Only hominids. Neanderthals weren't even around until 200,000 years ago.
The near extinction event discussed in this video happened tens of millions of years after we lost the ability to produce vitamin C. That happened in some stem primate. Edit: All of our nearest relatives (all the way to tarsiers) have the same broken GULO gene. That puts our loss of the ability to produce vitamin C at probably more than 60 million years ago.
I googled that and Tonga 2022 (a large “normal” eruption) was slightly more energetic than the Tsar Bomba and 500 times more powerful than the Hiroshima fission weapon. The Tsar Bomba wasn’t really a “weapon” as it was much too large to deliver anywhere. It was built in place as a proof of concept.. So run-of-the-mill volcanic eruptions are far more powerful than any actual nuclear weapon currently available to us. Supervolcanoes are many orders of magnitude more powerful than Tonga
Are you SURE it went to 1,000 humans? Because I had been reading for decades that the number was estimated to be about 20,000. But, to be fair, it seems that, given the better human genetic variation likely to be available at the time, 1,000 would be just enough to bounce back. I just have never heard it to be such a small number, ever, before this video.

And just thinking that something like the Wolly Mammoth was so important to humans for such a long time and now they no longer exist.

What I always wondered was how did they manage to work out they could make fire with friction and/or flints. I mean, if I already didn't know how, I might try with a magnifying glass but it would never occur to me to try it with friction. IQ would have a lot to do with it.
Aboriginals in Tasmania forgot how it was done and they kept two fire sites permanently lit where others could go to get fire. If those sites ever went out, they'd have been in big trouble.

It is one of the reasons why humanity is so uniform, both in morphology and in behaviour. Without this event, there would be much more variations in body shape, intellect, etc.
Crows and rattlesnakes are so uniform both in morphology and in behaviour. Your point?
@@mutteringmale In humans there's a severe problem in having a too closely related DNA which causes morphology and behavior, makes it more often that recessive diseases and deformities appear.
There it is, the big lie the churches, who control all your normal bodily function and makes you pay for it, has told you.
The genetic diversity is only really applicable in small populations, very small. Bad genes then get passed around and there is a TINY bit of malformed genetic code.
But then, there is the good thing about that also...think of those northern Italians in a tiny village since 100BC who 40% of them have a mutant gene that protects them from cholesterol, heart attacks etc.

That Mt Toba event in the Pleistocene epochs of the ice Age
We now know that Toba was more locally devastating than globally. While certain areas of humans nearly went extinct in many other places they were doing just fine.
75,000 year ago Mt. Toba exploded wiping out many humans, animals and plants. If there was a highly advanced human civilization say Ramachandra was more advanced that we will be in 200 years failed to stop the caldera. I would say it was a centuries long civil war that took more time and tech to maintain instead of ending it. Why they were caught with their pants down when it exploded. damaged it severely and 42,000 years ago was the final end to it.

900,000 years ago, that sounds about around the time humans started, and at one time there were just a handful of humans, the very first ones.

The population was too tiny and spread out, so groups would be unlikely to come into contact with each other to spread such a disease, particularly a fatal one that killed the whole band. Pandemics only become a thing when you have a denser population where the organism can spread easily.

Chicken Pox is a herpes virus. Anthrax has been found surviving in dried soil that was stored for 60 years.
Doubt it. Clusters of population were quite separated--occasional contact with other clusters, but bounded within available food regions. Fire was used for cooking and protection longer than a million years ago. But early migrations likely failed for many reasons.
