Researchers mapped the mammoth family tree by extracting DNA from fossils. Also, scientists found some sessile animals living under Antarctica's ice shelf, and they're really cool.

The Oldest DNA Ever Found
1 817 Shikime 183 mijë
Whoops...
Lo interesante son los lobos gigantes prehistóricos, leones gigantes prehistóricos de América, junto el águila de hast, si pudiera estudiarse sus cuerpos y como funcionan, así como que tipo de mitocondrias, células madre, membranas celulares y otras cosas tenían, antes de expirar el adn pues tiene períodos de vida y conservación de 12 000 años o 10 000 años, quizás en frío, congelado y en algo como miel de abeja reina, 14 000 años, sugerencia.
@David Asher All I can say is words matter. I'm sorry if you feel that's overshadowing the accomplishment. In my view, not explaining it clearly and succinctly is what is overshadowing this great accomplishment.
Delete this fool.👑😁
Also people stop saying "delete this too"
What happened?
Crazy vibes!👊👊
idk why but "boulder community" made me giggle
2:54 And Mother Nature just laughs at Humanity.....
What are you doing steppe mammoth
Plot twist: delete this too
Liberalism is a mental disorder
Says the mouth breather screaming about politics in a science based video....
Love these videos
Remember that story where Cinderelephant wanted to go to the ball but her wicked Steppe Mammoth wouldn't let her?
"A million years ago". Utter ROT! There's not a million years in the whole world added up together, never mind just lying around in a hole in Siberia.
Prove it creatard.
Come on now DNA can’t live that long. Ithasbeenwritten.com go see for yourself.
@The Blazedest I already shared the link
Oh but it can. Try and refute it 😂
is it possible to clone these ancient mammoth using their DNA?
Amazing!
What are you doing steppe mammoth 🦣😏
Not bad , but he speak much tooooooooooooooooooo fast to understand all .
1 million id pretty good. Make it 65 million and then we can begin the dinosaur parks;)
Well, I saw today only that Hank is also on Khan Academy But, just to confirm I watched this video...
Could you do an episode on all the lifeforms or discoveries of them, that scientist thought were impossible. Seems to be a recurring theme.
Nature doesn't need photosynthesis to create life...or the liquid vents and entire ecosystem on the sea floor... This research was not thoroughly acquired...
At 2:35, I don't understand. If Unknown Mammoth #2 interbred with Woolly Mammoth to create Columbian Mammoth, then there would be Unknown Mammoth #2 and Woolly Mammoth DNA in Columbian Mammoths. But that's not what Hank said. He said "That other separate group was a partial match for Columbian Mammoths and a partial match for Woolly Mammoths." That makes it sound like Unknown Mammoth #2 was the product of Woolly Mammoth and Columbian Mammoth interbreeding, not the other way around. A mule has DNA from a horse and donkey. A horse and donkey don't acquire common DNA because they produce a mule. You've got genes flowing backwards along the tree of life. What am I missing?
Speaking about discovering new things in frozen environments... sounds like checking the fridge for fresh items.
Clone the mammoth!! Jurassic Park for real!
I think the word evolution is being used very very loosely
Steppe mammoth, what are you doing?!
Sure. How about cloning it now?
How do they know the age of the teeth
Should've titled this "Like, I'm, uh, finds a way."
we need to consider hybrids in dna evolution for every species throughout evolution on earth
For the algorithm.
Hey aren’t you that guy from tik tok? 🤨
you forgot to mention that the rock under the ice sheet was found not only on accident but the one place with a giant rock that cant be drilled through. a huge inconvenience to those drilling, but a good find for other scientific communities!
brilliant video and awesome news . thank you
This discovery in Antarctica could be pretty big news to those pondering over the possibility of life on Pluto
Oh no, what are you doing, steppe mammoth??
Does this mean we can now clone it?
steppe mammoths look like asian elephants
You say "The World Beneath" and I think of Dinotopia, kid.
Still no 65million + dino DNA in Amber then. John Hammond you lied to me
Stop digging up Antarctica and the ice caps and shelves, please. They seem to be pretty important to keep them intact. Isn't that why we're spending a trillion dollars a week to protect earth from their destruction? Yet people are constantly over there blowing shîte up
If they're going to make a Jurassic Park type facility please only clone herbivores. . .
Can you help me stepmammoth im stuck. Wow what are you doing stepmammoth?
That DNA is older than every single Homo sapien to have ever existed
You are talking too intensely to listen to comfortably.
Nawww arw youw poor wittle eawes hewting?😭
Life finds a way even in hostile environments
Bla Bla Bla nothing new
What the hell is wrong with your hands? Are they on fire ?
wooly mamoths OR elephant neanderthal
1 billion year old dna found in fossils
3:48 Why am I seeing a fossil here
Another ridiculously edited speech. I miss the natural breathing pauses. Without them, I am unable to wrap up the sentences uttered by the speaker.
Yep, it's definitely hard to know about the Boulder community
The angsty teenage mammoth yells at the steppe mammoth his mom is dating ....."YOUR NOT MY REAL DAD! YOUR JUST A STEPPE MAMMOTH!"
How do boy mammoths find girl elephants in the tall, tall elephant grass? . . . . . . . Enchanting!!!
This comment section is lowkey ruined. This is a really cool discovery!!
I wonder if a large chunk of that glacial shelf melts if we will have an event similar to an algae bloom, but instead of algae, it is those creatures on the rock.
I love fossils!
As soon as you see or hear the word “million” years, be prepared to suspend your disbelief. Unless you just do so because you don’t understand something yourself. I’m at :12 seconds. Now I hit play to learn exactly this videos defense of “a million years.”
Lol silly creatard
Nothing. Learned NOTHING. Mammoths are elephants. Mammoths are NOT extinct. Mammoth DNA is PRESENTLY RETRIEVABLE IN MODERN ELEPHANTS.
Ok. I predicted this would happen based on YEARS direct observation. All of a sudden we are at l.2 MILLION years. Because a paper said so. The FED pulls the same thing. No explanation for the audience. “Move on son don’t ask any questions we don’t want any trouble here....”
Now we’re at hundreds of thousands of years......but no argument for THAT yet. Must be building up to that million years mark magically. Hitting play......
lets try to clone it, it works in all the movies
This is big news
I think they are going to be able to sequence Some later Homo Erectus DNA. Recently, they used teeth protein to sequence Homo Antecessor from Spain (Dated 800k years ago) and found that Homo Antecessor is a close Sister Lineage to the one that Homo Sapiens, Neanderthals and Denisovans split from. My guess is if they sequence Erectus they are going to find lots of DNA that was found in the Modern Human Genome, Neanderthal Genome and Denisovan Genome that goes back to Erectus. In fact, there is already some evidence for that already with respect to Skin pigment alleles, both lighter and darker, dating back > 1 million years. See Crawford et al 2017 " Loci associated with skin pigmentation identified in African populations".
What are you doing, Steppe Mammoth? 1:03
Anyone up to creating Ingen?
Me *extremely '🍃elevated🍃'* Thinking I'm an intellectual for watching scishow. Then me also realizing this content is used in grade schools to help educate our children 😳☺
Do desktop air conditioners really work or do they produce more heat than they mitigate?
Technology Connections has done an episode on just that. alfirst.info/load/Zp2mon-Sf8qmpHU/video Or for the larger portable air conditioners, he's done them too. alfirst.info/load/k2Kkcpy-eZd8eZc/video I have a feeling that you are already thinking pretty much along the lines of the answer.
I never knew my real Mammoth. This is my Steppe Mammoth.
I recall another video talking about creatures that photosynthesize geothermal heat rather than sunlight.
steppe mamoth : help me bro am stuck in an ice shard
Maybe the sessiles are feeding on the poop of all the scientists present on Antarctica?
What are you doing step mammoth?
wyd steppe mammoth
Could those animals be feeding on the boulder itself?
Steppe mammoth? I'm stuck!
Unknown hybrid is a good twist, the 6 year old me from the 70s was hoping for a Steppe Mammoth - Paleoloxodon hybrid but I'll have to wait until the next Godzilla movie for that
Man-moths?
WHaT ArE YoU DoInG StEppE MamMoTH!?!?
What are you doing steppe-mammoth?
What are you doing, steppe mammoth?
Evolution is awesome.
what are you doing step-mammoth
Ice moon life is getting more likely every day!
Excellent work!
Class, what did we learn today?
hey steppe mammoth I'm stuck
Wachu mean 1 million old DNA, world is not that old according to the Bible....
Why should anyone care what the bible says? It just makes claims then says god did it. Try again
Finding life under the ice shows the possibility of life on other planets that currently seem uninhabitable
Time to go Jurassic park on them!
Woolly Mammoth (stuck in a mud-pool): Steppe Mammoth what are you doing?
"Help me Steppe Mammoth, I'm stuck"
All thanks to real_hackman on Instagram for helping me recover my hacked Gmail account
Natural selection created an arm from a nose 🤯
Nice shirt bro
Teenage mammoth: "I'm sorry I said you're not my real mammoth." Stepmammoth: nods forgivingly
Ma'am-oth to you, cretin!
Wait are you saying Jurassic Park is impossible?? 😜
I think it is more likely that those lifeforms attached to the boulder get their nutrients from an outside source other than from their environment
Could the sea life be slowly digesting the rock for nutrients?
every time we find life in a weird place, i get more convinced that it's probably all over the universe and solar system.
Hmmmm... This cold community should and must be treated with all the biosecurity protocols we would use if it were an alien species. Ots such a novelty that it basically is alien to normal biology. Could bring lots of technological improvements (through it's biochemistry) but also could be dangerous to the normal biosphere (or, more probably, the normal biosphere could be dangerous to it)
Both these news are just how sci fi horror starts kkkkk Jokes aside, that camera could have just killed (contaminated) those creatures
Sessile 1. attached directly by the base : not raised upon a stalk or peduncle a sessile leaf sessile bubbles. 2 : permanently attached or established : not free to move about sessile sponges and coral polyps.
Boulder community. Boulder City origins!
