Imagine this soil technique applied to caves where our distant ancestors lived 30,000 years ago!
It has already started see Svante Pabo and his work in a German lab.
Imagine the poor kid growing up, knowing he was cloned from cave man poop...
I'm pretty sure our ancestors never lived in caves. They were just stop-overs that fortunately preserve evidence well - in part because people rarely go there, ironically. Elsewhere, timber and mud brick homes are soon washed away without trace.
Scary
I think that would be a great thing to do. We are the result of all the inhabitants of our planet in one way or another. DNA is the most direct of example but so is who we cohabitated with in domestic situations.
See, these are some of the people who make humanity extremely impressive, scientists wow me
Am I the only one who thought it was going to be pre-human DNA?
Probably not. Jurassic Park probably has a lot of people thinking we have a much better record of ancient DNA than we actually do.
Pre human, no.
So climate warming was there millions of years before modern humans?! 🙄 #FakeMorality #ESG #GreenCorrption
@@KimS_Pictureinpapre-humans are at least 2.8 million years old. But that is in Africa.
Yep
I had a little bit of trouble hearing the scientists voice as he was explaining the electric charge of DNA because the background music was too high.
DNA from 2 million years ago is so crazy I always thought it would be impossible
it is impossible, they like seeing just how gullible people can be
@@vade137 Or in your case how ignorant some are!
@@williamjackson5942 good luck with life Mr. Jackson.
I always believed it was possible and never understood why it could not be possible if the molecules are isolated and shielded.
A professional geneticist told me that she thought it would never be possible when I proposed the possibility years ago. And, here we are.
Nature doesn't care if we think the unlikely is impossible.
I think that if it is even minutely mathematically probable, then it will arise somewhere in the infinity of existence.
@@gandolph999 Either the decay rates are way off, or the deep time paradigm is way off. It's interesting how one is immediately considered to be the case.
Wow! We just keep learning more and more about the past and it is fascinating. History goes back so much longer than the short time humans have been here on this planet.
True, but these samples are only about 2 million years old. Hominids go back 5 or 6 million years. Though modern humans are probably a little bit less than a million years old.
By arranging atoms and molecules, what kind of creatures could we create for the future and for beyond 'Earth'?
@@charlesbrightman4237 There's a cool old sci-fi short story about parents saying goodbye to their kid who is leaving to colonize another planet. The kid's genetic modifications to be adapted to that new planet are described in some detail (I don't remember). The theme is very much about this very alien looking kid still being 'human' and loved by their parents.
The twist comes at the very end when it describes the parents slowly walking away on their thick four legs (modifications for high gravity).
That's not terribly realistic IMO. I don't think humans will bother settling on the surface of other planet... Makes more sense to just build habitats in space which have exactly the conditions you want. But we will use modified organisms for all sorts of things. Ultimately, materials are all mined, drilled, or grown... And grown is much more flexible/powerful.
@@travcollier Well, here is a thing: Either at least 1 single species from this Earth survives beyond this Earth, solar system and most probably collapsing spiral shaped galaxy, OR none will.
EXISTENTIAL ANALYSIS: (copy and paste from my files):
"Intelligence Preparation of the Battlespace"
1. Define who and/or what is the true enemy.
2. Then define the battlespace.
Nature is our greatest ally in so far as Nature has given us life and a place to live it, AND Nature is also our greatest enemy that is going to take it all away.
1. Define who and/or what is the true enemy. NATURE.
2. Then define the battlespace. Initially, this Earth, then this solar system, then most probably collapsing spiral shaped galaxy, then possibly even every galaxy in the universe that might collapse in upon themselves. (And the universe is not going to end in a big freeze). So finally, the universe is the ultimate battlespace.
Notes:
a. Besides mass extinction events here upon this Earth (possibly the 6th has already started due to Earth's magnetism issues), and the 6th won't be the last;
b. The Sun is supposed to become a red giant one day and will wipe out all life on this Earth if not even this entire Earth itself. (Sure, a long time from now, but the destination is set like a way point on a journey).
c. Our spiral shaped galaxy is most probably collapsing in upon itself and depending upon what is really true in this universe, possibly all galaxies eventually collapse in upon themselves.
d. Either at least 1 single species on and from this Earth survives throughout literally all of future eternity OR none do. Currently it appears that none will. Currently it appears life itself is ultimately meaningless in the grand scheme of things and currently it appears all of life itself, (at least from this Earth), is a waste of spacetime in this universal existence.
e. We do not have to defeat enemies here upon this Earth, we only have to outlast them. Nature will wipe them all out for us.

@@charlesbrightman4237 I'm an evolutionary biologist, for reals... PhD and everything.
Really long term thinking is one of the things I think I do pretty well ;)
I love how science fiction always informs actual science. Like our smartphones, tablets, and video calling. Anyone remember old Star Trek and the Jetsons? Now Jurassic Park is in the mix of SciFi that was used as inspiration.
How about Dick Tracy with his wrist phone?
This is fascinating. Thank you for sharing.
Boggles my mind how far we advanced in science
Almost like it happened way too quick like we never saw it
@@iamshango3005 That is how advancement goes. You will have decades or centuries without any "big" discovery, and then it only takes one thing to jump start a revolution. Maybe you should study history instead of claiming things are fake.
Boggles my mind how yall believe that someone can say something is over millions of years old
@@Finduski Stop being "boggled" and start getting educated. Open a science book, Google it, do something other then sitting in your ignorance. It confuses you because you don't understand it so learn about it. Religions like to keep people stupid and scared so that they can control you. Don't be one of those who refuses to do their research and just believes what they are told. You can learn for yourself how scientists come to this conclusion. And if you think that all of these scientist are wrong, then prove them wrong, you might win a nobel prize if you can show that they are wrong. But saying that they are wrong because you don't understand, just makes you look silly.
Have we?
Awesome! Love the information you provide! Thanks!
Maybe they dont need to have the Govt point a gun at my head and steal form me to pay for it?
😊
DNA fluids traveled down to those layers mostly with rain water. They really do not know how old DNA is or how it got there.
Water dissolves DNA
This is so fascinating
If it was tropical water in this time, then was the Earth's axis possibly at a different angle? Just a thought.
I too thought of this. But I've come to the conclusion that climatic changes are more likely the cause of a warm Greenland. An increase of less than 3° C in North Atlantic Current could raise Arctic temperatures significantly.
For 65 million years reptiles had it warm enough to inhabit the entire planet. The glacial period during which our species matured seems, to me, to be the interruption of an overall warm planet since the first thawing of "Snowball Earth".
We humans have evolved in a temporary "cold" era, that is (I think) drawing to a close. We filled a niche position in the beginning, for a world growing colder. But are we still as adaptable as our proto human ancestors? Can we cope, even thrive, in a hot world? I believe we are on the verge of answering those questions.
If you're asking that, you're probably aware that the Earth's axis DOES change angle, on a 40,000 year cycle (one of the Milankovitch cycles). But only by about one degree. That DOES play a role in ice ages and other types of global climate change, but by itself it's not enough to drive it. Many other factors play a role as well.
@@araptuga I agree. And that 40K year cycle doesn't really correspond well to the ice ages. I'm of the opinion that it is fluctuations of solar output, at least as triggering events.
We call our orbit "The Goldielocks Zone" and it is. But we are much closer to the fire than Mars, which is a cold planet. And we have a massive volcanic heating system. It would therefore be logical that we would be a hot, wet, planet a great deal more of the time than a partially frozen one.
Think the Amazon Rain Forrest from Florida to the Appalachian Mountains. 👀
Global warming
araptuga I wasn't actually. Just the fact that there are tropical like waters there would indicate so. What other factors if you don't mind me asking?
That's amazing!!! Good job and thank you for your hard work. Also... thank you for the video. Knowledge Rocks!
Cool! Good work, keep it going 🌎🌍🌏
Cool. Thanks for sharing.
Thank you for this information. Hoping my preserved DNA sample projects survive at least that long. Will have to look into the binding process for my next project I'm now working. Cheers. 👍👍
Found warm-weather horseshoe crab . . . But ice preserved it. Huh?
Lol
@@iamshango3005 It's nice when any dissent is censored. The contradictions in their story never get challenged.
@@johndodson8464 Seriously? Many warm weather areas became ice covered as we have gone through several ice ages. Damn, go back to school.
@@leehamilton4459 Wow, cuss words really show your pedigree. I'll go back and read that chapter about horseshoe crabs wearing parkas.
Exciting! Can’t wait to learn more.
Hello 👋 how are you doing?
Background MUSIC IS TOO LOUD! Why do content makers continually do this?
I bet there's something even older deep in the Artic.
😂 your mom
This was spectacular
Outstanding!!!👍
Thank you 🙏
EXCELLENT!!!! 👏👏👏
Wait... I'm not one to be skeptical of science but why is one man digging in the soil with his hands, not wearing a hazmat suit but the other two people there with him are suited up?
Dramatic recreation.
I think there is something going on with our planet. Where lakes n rivers are drying up they find ancient writing on the cave walls meaning water wasn’t always there. Now they find DNA that shows a warmer climate in what today is frozen over. Pretty amazing how our planet does this shift.
This is SO cool!
Or warm
Iceman (1984) is a fantastic movie.
Not surprising only further adds to plate tectonics, where there was ice used to be tropics
Incredible
Fascinating.
DNA, y'know, finds a way
It’s the most awesome force this planet has ever seen
So interesting! Just please dial back the syncopated music. 🙏 Thanks!
Ill give folk an idea of this DNA extraction process, it takes over 30 steps to get it out of whatever it is your taking it out of. I had a lecturer in college who was in the process of inventing a new extraction method and our class was the 2nd to be the guinea pigs to see if it worked. It was very difficult and the precision was a nightmare, you mess up one step and you have to start over. We did fairly well considering it was all experimental. We did it twice, once was identifying species from poop, and the second was identifying what had been in some clay pots, ie plant or animal oil.
FASCINATING!!!❤
Fascinating findings! This is what real scientific research looks like - 15 years of frustration to reach a pivotal moment of breakthrough technology. This video is a tribute to not only these scientists, but scientists of every stripe who are doing real research to help us better understand the past and the future. I would suggest, however, that scientists drop the political buzz phrase "climate change" and instead speak of "environmental change" -- the climate is always changing, and two million years ago, that change had nothing whatever to do with human activity. Science is and should remain above partisan political ideologies.
Just wait! It's going to get interesting!!!
Remarkable! That's the thing I love about life. You never know what tomorrow will bring 👍 fantastic
Horseshoe crabs are way south? We have them in Connecticut.
Wrote a poem about this video. I'll call it..
"Frozen polar desert"
Within the soil
lies a genome
binded to minerals
polymers find a-home
40 million years
And only now we start
Proud of this time, we say
" We're state of the art!"
Trying to understand
an ancient ecosystem
Compare libraries for clues
Just in case we missed 'em
A frozen polar desert
we now call Greenway
to understand the lineage
How we got here today.
Thanks for sharing your poem. That’s fun!
Inspirational 👍
Wow! I love it! 😊
Awww man, I knew I shouldn't have left that there.
cool
best wishes thoughts and prayers for ALL
ONE 💛
Well time to learn about the world's oldest Ecosystem
Biden's colon!
pretty cool, can`t say i understood a word of what those scientists said - but it looked like they are having fun. lol?
This is because before the last Micronova/Poleshift life may have been silicon based. Things may have been A LOT bigger too. The Arctic may have been in a more temperate climate. This is probably why dating ice core samples is so hard.
As far as I can tell, there is not any evidence that life on earth has ever been silicon based. Fun to speculate though!
Life goes on...
So; could DNA traveling through space in a cold asteroid survive millions of years? Could DNA on a destroyed world be preserved in an asteroid?
I love it when scientists prove themselves wrong. It means the scientific method is working.
Wow. I can only wonder what we will find in the future in our analysis of soil in the exploration of outer space. Could we recognize alien DNA?
A million years before the 4 Ice Ages that really disturbed everthing. A whole new doorway to discovery. Nobel prize?
Dna of what species?
the power of science! Society needs fewer marketers and advertisers and more scientists and engineers
How could the make money? You also need to remember the intelligence bell curve
. They never come to the conclusion that it's not as old as they think it is.
Because that's not true and it's you who never comes to the conclusion that it's way older than you think it is.
Wow so cool literally cool.
Sick
Greetings from America, graduating from college with a bachelor's degree in science and technology, the current find is interesting to me by the 3rd power. lol Congratulations to the scientists.
What does AyKShieNT mean?
Súper interesting 🤨
Amazing. So, if I understood well, in the same place of today's that frozen land, one million years ago the climate was much much more warm, with species that today only can be found at southern lands... My question: how can that be possible if the sun radiation was the same than today? I also want to underline that in this region they suffered, as today, long periods without sun, which implies even more interrogation about the real reasons of the climate change.
The perfect question. The answer? Climate goes in cycles, it is not man made.
Hey they should test more of those elongated skulls…
If you're talking about the kind of skulls I think you you are, those skulls were shaped by binding them with boards, fabric and twine as infants, not because they were alien hybrids, or some such nonsense. They were entirely human. Don't be more embarrassing than you have to be.
@@DrachenGothik666 I’m not embarrassed for asking questions but you should be for being so sure of something. It’s definitely not cranial binding in *every* case lol that doesn’t increase brain volume remove sagital sutures change spine position etc. And we are definitely a hybrid species with them alien or otherwise. And so what if some of them were cranial binding it was because there parents had the feature and their hybrid kids didn’t so they were trying to retain it. And I could be wrong but that’s why I’m saying they have better ancient dna testing technology and they haven’t identified the father of any of the samples as far as I know but they all came from the Black Sea region where you have not so far the ancient Sumerian whos religion one of the oldest in the world specifically says just that that they are aliens and the Egyptians of which Akhenaten matches anatomically the paracas not just match but identical and they are found near megaliths all over the world. It’s okay with me either way but the evidence can’t be ignored and should be investigated further.
I’d dare someone to consume it !
Drop the music!
It is deceiving regarding "how" the DNA fragments were dated. Was it really that old? If you ask the scientists they will acknowledge that they are making assumptions.
Wrong
Dude has a really unique accent.

Maybe we should start sequencing oil
Way way way down at the bottom of the laundry basket.
The main secret is that ancient city found by Chile explorers the one the pentagon took over forbiding anyone to get near the area
Yes, wait and see.

But how did they date it?
Many years of dinners and flowers 💐
What if, Greenland wasn't always so far north?
This isn't the world's oldest DNA -- it's not even the oldest DNA from that part of the world. Mummified wood from a 45-million-year-old semi-tropical forest on northern Canada's Axel Heiberg Island was sequenced by genetic researchers at the National University of Altai in Russia, and found to be almost identical to the DNA of modern woody plants.
Was not frozen but lush green and wooded areas
Was the certificate guaranteeing that it is 2 million years old present with the sample?
That isn’t a method used to make such a determination.
@@moonshoes11 I know but the method that is used is definitely less than 100% accurate. Lots of it is guesswork based on nothing definite.
@@mikeabc5355
Dude, you’re looking for a certificate.
You know nothing about the methods used or their accuracy.
And you probably believe in magic.
@@moonshoes11 “dude you’re looking for a certificate” clapback of 2022 thank you mr Moon 😂❤
@@moonshoes11 Ahmmmmm, you do. It was self riches low IQ individuals that insisted vaccines would prevent you from getting covid and passing it to others but as it turned out it was all BS, however, the pharmaceutical industry made billions.

Where's Waldo?
I did not know DNA was electrically charged. I shoulda, but I didna.
Just shows we know little about the pass, what lived and how long.
Anckshunt DNA
Nice computer code.
Well well. They found the proof.
A horseshoe crab isn’t a crab, and shouldn’t be referred to as such.
Not possible... but if true, amazing
Extraction techniques have needed to advance to get at available samples.
Why is it not possible if molecules are sufficiently isolated from radiation and enzymes?
Impressive, but is 2 million years considered deep time?
As far as finding sequence-able DNA is concerned, quite possibly.🙂
The world’s oldest sock?😂😂😂
We'll be ancient history soon.
Uh, "who" said that it was this old (dna)? No one is "the" final word on dna.
DNA binds to clay and God formed Adam from clay, interesting
God is imaginary. Please don't inject your stupid mythology into scientific inquiry. It has no place, here.
So did god create Adam or was he already in the clay?
I have 11.3% unknown gene from Arctic And North East Ancestry
#ComptonCaliLove
Greenland was green? Who new.
So it's alien life form
This means there is ancient dna everywhere
No. So far, it's saying as long as we find this combination of prolonged cold climate and certain minerals.
@@gardengeek3041 Clays are everywhere and every has much lower temps under the soil where the clays live
But for me is yes you can in everywhere
But don't be got dangerous dna because something happen in the future
greenland was prob on the equator at one point, shifting magnetic poles and asteriod changed things.
May be why dating ice core samples is so hard? A crustal shift may be our near future too.
Maybe 400 million years ago, but not a mere two million years ago. The continents haven't shifted that much in that time frame. Tectonic plates take a *LOOONG* time to move that far. There are sites online that can show you where the tectonic plates were positioned at various points in time, if you care to go look.
@@DrachenGothik666 the crust is sitting on liquid lava, you dont think a rogue planet passing thru the system cant tug at our crust and put the America at the north pole as it zippes outta the solar system?
@@BlazinRiver1 No such thing as a crustal shift. That's not how plate tectonics works. Somebody must think the movie 2012 was a documentary. lol
And how do we know it’s 2M years old?
Oh that’s right, they used the strata to judge the age of the fossil. But how did they know how old the strata was? Well, they used the fossil to determine the age of the strata.

A kid growing up in the fifties and told there’s nothing new under the sun...🧐
I grew up in the fifties and no one ever told me such a thing. I was always told we were on the brink of amazing new discoveries we could never imagine.
