Just in case I was not clear in the video. This is not an attack on the impact hypothesis. It may well be true and serious scientists are investigating the idea.
However, I do strongly object to the accusation that archaeologists and scientists are hiding the truth from the public. I often find that those who suggest this idea are more than happy to cite scientists that agree with them but disparage and attack those who do not.
I hope I showed that these issues are very complicated and that any disagreements exist for good reason.
As always there is far more to this debate than any one video can show. Thousands of archaeologists, geologists and scientists of all shapes and sizes are trying hard to understand the ancient history of our planet. If the evidence shows that an asteroid struck, or we find cultures we did not know about before, then it is because of their hard work that we will know that.
Thank you for watching.
Good job man, you have a very serious and interesting channel
We have like 20+ very similar so called Dansgaard-Oeschger events in the near 120 000 years, some colder and with more wild fluctuations.

I know I'm a bit late to the show on this video, but while ancient aliens and other kinds of Atlantean civilization theories might be wacky, Gobekli Tepe and Nevali Cori provide staunch evidence that architecture was at least somewhat advanced in the younger dryas beyond what most people thought ten years ago.

Im another to believe humans were more advanced in Knowledge & application far further back than what is generally accepted.

@@combatflowarts Yep, the fact that humans were more advanced than we thought is well demonstrated today.
Yes, sometimes I toy with that idea too, I really love Assassin's Creed..still I cant accept the idea of trasmitting knowledge because all the findings say that was a slowly and realy imperfect learning curve.
Will you talk about the paleolithic human impact on the amazon basin one day? Most people think the jungle was a wild land without any cultivation or human impact, a view that doesn't stand up well. Domestication of Thoebroma Cacao and other crops occurred in the upper amazonian basin around 5,300 years ago and many of the foodstuffs we find in the amazon today are in fact cultivars.
Yeah I'd love to someday, it's just a matter of time. Thanks for watching.

@@StefanMilo I would also find it interesting if you were to cover the possibility of ancient Mediterranean basin civilizations, back when the straight of Gibraltar was perhaps a massive waterfall.
sorry but there was no Palaeolithic in the amazon basin. no humans in the amazon at this time
@@BaltimoresBerzerker I am not a archeologist and my use of the word paleolithic might be mistaken, from a cursory glance at the wiki it seems that the pleo/meso/neo lithic ages depend on regional advances so maybe I wasn't using the correct term for that time period in that region of the world. However yes people were here at the end of the paleolithic period. I realise that there is a lot of controversy over when humans first got here but the selection of crops and improvement of their yields that occurred in the amazon has some decent evidence for it. Wild cocoa pods yield very little and have thick walls, cultivars produce more juice and more beans and we have found ceramic fermentation vessels throughout the amazon/Andean foothills. www.nature.com/articles/s41559-018-0697-x
Only just got round to watching this one but was well worth the wait. Superb stuff
I agree. For those who wish to explore the science, this Wiki entry provides an overview.
"The Younger Dryas event, notably its sudden end. It is the most recent of the Dansgaard-Oeschger cycles and began 12,900 years ago and moved back into a warm-and-wet climate regime about 11,600 years ago. It has been suggested that:
"The extreme rapidity of these changes in a variable that directly represents regional climate implies that the events at the end of the last glaciation may have been responses to some kind of threshold or trigger in the North Atlantic climate system."
A model for this event based on disruption to the thermohaline circulation has been supported by other studies.

Hi the other Milo recommended you on his channel so i figured i would check it out. Ill be honest i believed Graham Hancocks claim about the Young dryas but after doing my own research on it im starting to see how much is misinformation and this video also helped so thank you for posting the real truth cause we people really need more of it these days. Great video, hope you are doing well.
Hancock is not spreading misinformation. Some of his speculations are weakly supported by facts, but the facts he does give are accurate. His antagonism towards mainstream archaeology is unfortunate but understandable when you view the patronizing reactions to his ideas.
@@jacquesstrapp3219 I have no idea how you could've interacted with any criticism of Hancock's work (or just the info in the video above!!!) and still come away with the idea that "the facts [Hancock] does give are accurate". The man lies constantly, e.g. by misrepresentating what are demonstrably natural formations as man-made, using soil carbon datings as dates of human activity, presenting Younger Dryas sea level rise as a cataclysmic flood,... He's absolutely spreading misinformation, and the fact that he does regularly interact with actual scientists makes it almost impossible for him not to be aware of it.
@buzhichun You just did what you claim Hancock does. You misrepresented what he says to suit your agenda. The epitome of hypocrisy. Since I am familiar with his work, I instantly recognize when you lie about what he said. For example, you said he misrepresents "demonstrably natural formations as man made." Two things are false about that statement. There is disagreement about whether features like the Bimini Road are man-made, and Hancock says so. He states his opinion that they are man-made but nowhere does he claim this as fact. You claiming he did is a lie. On closer examination, the only one misrepresenting anything here is you.

Well done as usual, but you neglected to mention why the Younger Dryas (and the Older Dryas) have that name. It’s because during those times, a small, cold-adapted flower in the genus Dryas became much more abundant. The genus is named after dryads, which are a kind of wood nymph in Greek mythology.

These scientists are not archaeologists, but paleoecologists. Source: I am one.
Fabivs Agree. I don’t see this subject as being as contested as it’s made out to be by either side. It appears that in the past ppl simply didn’t dig beyond a certain point & dates as to when things were possibly built might have been assigned to incorrect periods. The entire process of what we believe about humanity & civilization also contains facts that may have been misinterpreted. I believe that in time ppl like you will find other sites & better interpret existing sites. Do you have any theories about Gobekli Tepe? I believe that even with that “groundbreaking” (pun intended) site that it’s real use & significance was missed at first but that some are realizing how it was truly linked to civilization.
If I may make an attempt: Archaeology, traditionally defined or conceived, is concerned more specifically with the human past, however ancient (hence the root "paleo-", as in paleoanthropology). Paleoecology is thus more general, since it is the ancient history of climates or ecologies, which includes the human place in the environment, e.g. as subsistence evidence or causal factors. But there is certainly overlap between the two disciplines, for example, dating methods and intertwined scientific narratives. The original post or video presenter are welcome to nuance my response or to correct me. Hope my attempt to answer helps!
J. A. Smith I’m just a fly on a wall here but that’s impressive. I’ve found it interesting that some on each side misrepresent the arguments of the other side. This video isn’t the first to allege that the other side claims some vast advanced civilization connected across the globe when in reality some are just saying that there might have been a few tightly centered cultures that had contact with one another or that spread. At the same time, although I respect Graham Hancock, he seems to be saying that those opposing his ideas are dogmatic in refusing to evaluate new information instead of recognizing that these “fields” change slowly through a peer reviewed research. In other words, if a 20,000 year old civilization was unearthed today, although it might not be recognized as such immediately, as evidence mounted & was subject to peer review, it would eventually be accepted.
I honestly believe that Gobekli Tepe is linked to other settlements that have yet to be discovered & that it’s purpose was much more practical than current theory. Although we acquired wisdom as we age, the worst part about realizing that our lives our relatively short is knowing that we won’t live long enough to gain the knowledge of major discoveries in the future. Someday we may find even single cell life exists elsewhere in our solar system or we may find an archeological site that rewrites everything we know today. That’s why the work that you & others do regarding this & other subjects is so fascinating to me & more importantly, of great significance to all of humanity.
@@r.williamcomm7693 Yeah, a global civilization doesn't have to have billions of people crossing the globe on airplanes. It could have easily been a civilization like the macedonian empire or the Roman republic that crossed the sea and setup outposts and trade with other cultures. I'm not sure why this theory is so far fetched. If someone like Alexander the great knew about continents on the other side of the atlantic he would have tried to explore it. People often forget that ancient humans have the same brains and minds we do, they weren't primates living in caves and worshiping snakes.
@Bitchslapper316 Agree 100%. There’s a great documentary style film here on CZcams about the Egyptians, how they built the pyramids & how they they are proposed to have traveled to South America, India, & even Australia. Let me know if you need the link.

This is a great presentation. Don’t sell yourself short - you may not be a research scientist in this field, but you are well informed. Plus, by NOT being a scientist in this field, you can look at this subject objectively, unlike those who are married to a single hypothesis. Thank you for a job well done.
Calling other non-scientist ideas 'whacky' is selling them short, so Milo can sell himself and his spoon short along with them.

This has actually helped me with something. The Bolling-Allerod warming period was as abrupt as the Younger-Dryas; it’s all one event. The warming was triggered by warm water turning over in the ocean, warming the Earth. When the Feedback loop was complete and freshwater poured in, the cold began again.
What we are going through now is probably the same thing. Air temperature isn’t causing the ocean to warm, the ocean turning over is causing the climate to warm.
There is always a cause and effect debate within science but given this has become a political issue, people have seized it as a means of control so it’s “settled science”, which should alarm everyone.
I think they have the cause and effect backward here and we are dealing with another abrupt warming period, not caused by humans but by Co2 being released by ocean turnover, the same as it was 15,000 or so years ago.
Well done, Stefan. I didn't see it as an attack on the impact hypothesis - you were very clear on that and your position seems completely fair to me.

Missing shoulder blades on the mamooths. Shows they were righthanded and they needed those for making (probably) digging tools. Check out the prehistoric channel of Will Lord. Particulary the one episode where he shows the prehistoric flint mine in england and points out that fact that all the tools were using the left sided bone. tools like mining pick etc.
That's an interesting idea, I hadn't thought of that.
That was my first thought, that it was probably for right handed tools. Thanks for recommending that channel!
Digging tools aren't particularly right-handed or left-handed. I use shovels right- or left-handed depending on my body position relative to what I'm digging. And that's what you'll see if you observe people doing a lot of digging.
@@tohaason absolutely not! People have a preferred side to use things such as shovels or brooms and other such tools and will switch to a less preferred side when tired. If you don't have a tool like a shovel that can be used either left or right handed and are reliant on a shoulder blade bone you would of course choose one that fits your preferred side and just stop to rest as switching sides isn't an option...

Time is relative. A second is a long time when your life is in danger.
I’ve been trying to figure out how many generations of human beings could be said to have lived in that 1000 year period. Assuming that the average adult Homo sapiens back then lived to age 25, that’s 4 generations every 100 years, for a total of 40 generations. The climate could’ve re-shaped the genetics of our species considerably during that time. And the forced movements of groups of people southward to avoid the intense cold could have accelerated the rate of interbreeding between different populations, including with Neanderthals and Denisovans. I can’t wait to see where the science leads us with regards to these issues.

Recently read a paper about the human genetic bottleneck around the Younger Dryas. They think that in particular, there was SEVERE contraction in male (y chromosome) diversity. Possibly leading to a F:M of 17:1. Their hypothesis was that during stressful times, male birth is less likely. They supported this by looking at Japan, and their three most recent disasters. In all cases, 9+ months later, there was statistically significant decline in male birth in the local areas following disaster.
I find this really intriguing. Is there some kind of built in feedback system, in our genetic code, that controls our population????? This could be a potential Fermi Paradox solution. Life always balances things out, between all species.
Fetuses are female during the first few weeks, later they developed further into different genders, since the male fetus is more vulnerable they say, the mother body would 'spare resources' during stressful times and thus more 'effortlessly' girls will be born.. After wars, more males are born because may be because life gets better and there is a boost to every thing and more 'resources' for the mother and less stress on the fetus.. And also, think of it, females are more needed during stressful times because children must be born to cope, thus 1 male can impregnate 17 women quickly, and so on and so on
@@Ava-cy6qw how can 1 male impregnate 17 females more quickly than 17 males can? I really don't get the logic in that

This is the first video I’ve seen of yours; I just wanted to say this was great. Super informative. Keep up the good work!
It annoys me to no end that people keep insisting it had to be "One OR the other, but NOT multiple causes!!" for stuff like this. Dudes, real life doesn't play one card at a time. It's several cards at a time, some malignant, some benign...and sometimes it's more heavily drawn to one side or the other. Personally, I think it was several things that happened over a span of a few hundred years, some of it clustered tightly, some of it spread out, but all of it enough in combination to tip things the wrong way.
Did the North American ice sheets melting around Hudson Bay drain along the northwest, east, or southern routes? ...Why not more than one? Maybe one direction drained more than the others, but more than one is absolutely possible. Landscape isn't like the absolutely smooth, level rim of a pot, so it could've poured off in more than one direction. (Also, the whole Columbia Basin has been proved to be a massive flood zone, contributing further to freshwater desalination of the Pacific, though not quite at the same time as the Hudson Bay area draining.)
Based on the unusual minerals found I think one or more meteors may have been involved, possibly meteorites whose impacts were blunted by the ice so there would be little evidence on the land deep underneath. (A mile or two of compacted snow & ice makes a great catcher's mitt, wouldn't you think?) And volcanoes? Absolutely realistic!
Fire storms? Sure! If weather was disrupted so severely by something that there was a lengthy drought in the summer season, with little snow for a few years to soak into the soil and thus into the plants, forest fires could spread for thousands of miles unchecked! Any single one of these things might not be enough, but more than one? It's almost never one thing alone.
Assuming just one catastrophic event alone caused a massive worldwide change like the YD means that one thing would have to be truly, immensely catastrophic to affect the whole world. It'd be like a tank versus guns, knives, and matches. The evidence for its impact would be as undeniable as the KT-Boundary that ended the last age of the dinosaurs. But since we DON'T have a metaphoric smoking Howitzer barrel in the geologic record, then it had to have been a "perfect storm" of MULTIPLE different things that occurred closely enough together to cause an add-on effect.
That is certainly what the Ice cores reveal. It's not steady and linear, like the Uniformitarianists insist it was/is. Even coming out of the last Ice Age the weather was swinging wildly every few hundred years. And there are dramatic spikes that look like outside forces impact the weather. We are spoiled. It's been nice weather for hundreds of years, allowing crops and technology, good health, science,... allowing us to believe this is the way it should always be. We couldn't be more wrong about that. WHAM! It could change everything,..overnight. It has in the past, many times.
ladyofthemasque you make a great point and I think you're right. I think what happens is scientists look at their area of expertise. So someone researching ocean currents looks at some parts, then geologists look at their area. When these scientists all get together on everything then there's varying opinions on what happened overall.
MegaDawg342 yes! We have been living in a docile time overall. Doesn't give us much perspective. Thank u and great point
@@Andy-1234 arguably our geologically calm period gives us very good perspective since we aren't struggling with survival against a harsh climate. though we will very likely be all too soon.. also, looking at things in terms of a lifetime or two doesn't say much. if there's anyone to look back in 5-10k years, they will have proper perspective on our time.
@John Barber LOL
I had no idea the younger dryas was considered controversial. I thought Jim Teller’s work on a catastrophic release of glacial Lake Agassiz shutting down the North Atlantic thermohaline circulation was widely acknowledged as the mechanism for the cooling.
You can blame joe rogan for that. I came to know about younger dryas through him though
its controversial because theres soo much mounting evidence over the decades that is supporting some sort of impacts
it could have been both an ast
The Younger Dryas is not controversial, but the impact is. I think the impacts may have triggered that Lake Agassiz release.

I do appreciate the sober take. There is a newly found impact crater in Greenland. I know it hasn't been fully dated, but due to lack of erosion it can be young enough to fit the bill. Should have at least been mentioned as a possible candidate as it is.

Hey Milo....
The mammoths and mastadons living on islands have neither the territory nor the numbers to maintain a population in the face of both changing climate and human predation. It is logical to surmise that once humans came to these islands, it was simply a matter of time before the population of mammoths became unable to sustain itself.
Unlike the plains of North America where there were millions of animals roaming millions of square miles of territory with the time and numbers to maintain a healthy population. And you have to remember, it was not only the mammoths and ground sloths that took a hit.....there were dozens of other massive species that all disappeared at the same time.
Attributing the extinction of millions of animals, strictly to a relatively small population of humans doen not make sense.
Their extinction is definitely not a human activity.
Recently we have similar event involving Reindeers; Search:
Over 200 Reindeer Have Been Found Dead in Svalbard, Because of Climate Change
The clues are in the article:
The food shortage, the ecologists believe, was brought about by temperatures in the Arctic. This results in higher rainfall during Winter, which freezes on the ground, producing a hard, thick layer of ice. Usually, the reindeer can dig through the snow to reach the vegetation underneath, but the ice layer is impenetrable, so the reindeer starve.
In addition, warmer weather can result in a longer breeding season. That sounds good, but in Winter that results in greater competition for food, and taking greater risks for food, climbing the sides of mountains to reach higher vegetation. And the weakest animals are less likely to survive. That means the older ones die first, but so do the very young.
This mean Mammoths might be vulnerable to the same rain-ice forming process.
Remember the release of excessive water pour into the ocean? This might mean a lot of rain, sudden humid climate in one day- but because the process of the End of the glacial is not finished - in the next day - very abrupt cold changes that freeze all of that moisture - making the land impenetrable ice field.
And the YD boundary is black. Meaning this indeed may be a layer left of rotting vegetation - a humid condition can attribute to rotting, but also if it rains and all of a sudden waves of cold weather freeze that vegetation - it can preserve it even green for the next spring, where it will rot - again in humid conditions.
Finally, thank you. People seem to forget half of the world’s megafauna went extinct, not just a couple of mammoths. That’s millions ad millions of individual animals!
Overhunting by human is the only explanation that does make sense for the extinction of Pleistocene megafauna. Even low levels of human hunting would have had catastrophic impacts on slowly reproducing large mammals. Migration routes would have been disrupted because humans would be ambushing whole herds. Evidence suggests extinctions occurred at different times at different sites, indicating humans and no other variables were wiping megafauna populations out.

Hi Stefan, Just so you know, I am a member of the Comet Research Group who purposed the YDIH, and I will be the first one to tell you that the Younger dryas period is probably the most complicated example of Climate change ever experienced by Humans and the puzzle still has many missing components to fully understand what actually happened. But we have 65 PhD's from nearly every discipline of the Earth Science's and many many other highly educated people working diligently on scientifically locating and finding the evidence that will answer the most complex event in human history. Having said that, I am convinced beyond any doubt, and from personal boots on the ground research all across North America. 12900 years BP, a Cosmic Comet or other extraterrestrial Object's Impacted on the North American Ice Sheets and accelerrated the melting and massive melt water floods poured into the oceans raising the oceans by 400 feet. The rapid floodingof cold fresh water shut down the Oceans Thermohaline currents. This completely shut down ocean currents carrying warm water to the North like the Gulf Stream. This is the onset of the YD. It took 1400 years for the planet to recover at 11,500 years BP. We will be publishing on a new crater discovery within the year. Stay tuned.
Interesting! I'm curious why the GISP2 found the platinum spike at 12,895 BP but the ammonium spike 30 years later.
Why the delay? And was the burning regional or global? It is a fantastic puzzle because we have so many pieces, but the total picture is still unknown!
Therefore, if you have an opinion on this, and you do not have a PhD in the subject and work in this group, you're probably best not commenting.

Interestingly, Michael Shermer recently conceded that Graham Hancock was correct about some of his assertions.
well he had to, it was finally proven after impact remnants were found in syria and thousands of rogan-people were probably bombarding him with that when it first came out.
what he said was that he hadn't given the man a fair shot, not that he was/is correct.
Presumably, the simple effect of the crust rebounding as the Ice is lost could also produce enough geo instability to produce the same overall effects as would be caused by an impact?
The Wrangle Island mammoth population seems to be poster child for the isolated population of large animals you've mentioned. They were apparently suffering from heavy in breeding which seemed to have cause a loss in hearing and other stuff. And around 2000 BC the population succumbed to their genetic problems.
Wasn't there a huge crater found under the ice in Greenland, that scientists say it must have occurred relatively recently? and if it did happen, judging by the diameter of the crater, it much have been a fairly catastrophic impact.
Actual large chunks of meteorite from "the largest meteorite fall in history" were found there, dating from about the right time In other words, some scientists deny there is any good evidence of a strike and we have pieces of the meteorite already in hand as proof. basically a case of the one hand not knowing what the other one was doing. one video on the crater is Massive crater under Greenland's ice points to climate-altering impact in the time of humans - czcams.com/video/gg0mAihbm58/video.html
2 craters were found.
There's also an 18 Mile crater in the Indian ocean under 12,000 feet of water from 6000 years ago.

Hard to fathom when human industry isn't there to blame...
Do you have a citation for that figure? Ive only ever found estimates of 200 feet rise during the Younger Dryas and that was over many hundreds of years. Either way, the heat source would simply be a slight rise in average global temperatures causing a slow and steady melting of the ice sheets.
@@SW-cu7sh not hard to imagine at all. It was caused by Earths Milankovitch cycle in relation to the Sun. As for the current warming trend of Earth, the rapidity and timing cannot be attributed to said cycle. Therefore it has to be from some other process. Since the Suns total solar irradiance isnt increasing and is in fact decreasing somewhat, then that leaves the other driver of climate... CO2 levels. Since Humans are, in fact, producing magnitudes more CO2 than any other known geologic process then it starts to become clear that our activities are indeed the cause of recent warming trends.

Good video. Such a relief to watch a video where the presenter isn't shoving his personality in your face.
This might be slightly unrelated but I find it interesting how the melting of the giant ice sheets following the Younger Dryas may provide a more scientific explanation as to why so many cultures have flood myths. Besides the fact that most major civilizations formed on the banks of rivers and seas placing them in the path of regular floods, the fact that catastrophic glacial lakes would break through ice dams and flood massive areas more dramatically than any "bad season" on the Euphrates may help explain the prevalence of flood myths in religions across the world. If anyone managed to survive these glacial flood pulses, it would certainly be a story worth telling!
Also, even if water rose slowly after these pulses, it would still cause bands of people to abandon their usual lands and move into places potentially occupied by other groups. The creation myths of places around the Persian gulf sometimes feature fish humans or creatures emerging from the water. This seems reasonable to me considering that part of the world was critical to homo sapiens and, during the ice age, would have been habitable land. However, once sea levels began to rise, the Persian gulf would have been slowly turned into wetlands, swamps and eventually a fully formed gulf. The people living there certainly would have been forced out at some point but not before their attempts at adapting were proven futile. They would then move into higher, dryer regions and encounter the people who would eventually write them into their stories.
But these are just my theories.
I think that is right
I don’t think you need a mass flooding event. Any seasonal flood could be the source of the story, a recurring event such as flooding would have great storytelling power.
@Stefan Milo Great video! Had one question after watching, what was the cause for the melt water pulses? If scientists agree that they occurred, why is there no explanation for their melting in the first place?
It took me the whole video to realize the relevance of the mountain maybe I’m still wrong but I never even stopped to think how cold it is in the mountains. This man just perpetuated himself getting colder just to teach us bout the younger drias respect.
