Should we bring extinct species back to life? | DW Documentary

- All around the world, scientists are working to recreate lost animal species such as the mammoth. Using modern genetic techniques, they’re extracting ancient genetic material from museum exhibits. Do their efforts represent hope for the future of the natural world? Or is science playing God?
Findings in the thawed permafrost of Siberia have made it possible to reconstruct the DNA of mammoths. Researchers are now experimenting with inserting genes related to the ability to resist cold temperatures into the Asian elephant, which is related to the mammoth. The animals thus created could survive in the steppes of Siberia and Alaska.
In Australia, scientists have managed to extract the genetic material of marsupial wolves from preserved embryos in museums. The predator’s genes are replicated in the lab and implanted into the related marsupial mouse - in a bid to bring the extinct creature back to life.
And biotechnology could also help white rhinos in Africa: Researchers in Berlin are fertilizing eggs from the last two living females with sperm from deceased males frozen and preserved for decades.
However, these practices are also attracting criticism. Biology researchers question the usefulness of revived species for natural habitats. They fear that the excitement surrounding the idea of bringing back extinct species could distract people from the many problems that cause animals to disappear, in the first place. Are some scientists playing God - with unforeseeable consequences for the environment?

Restoring extinct species where their habitat still exists is an excellent idea. Preserving nature to prevent further extinctions is an essential idea.
So we are done nuking each other??? Are we done abusing each other and call it capitalism?????
They talked about bringing back the mammoth to try and save the melting tundra in Siberia, I think. DW did a doc on it a couple of years ago.
@KevinN-df8eo that's a fantasy. They didn't save it last time they were alive
precisely
and maybe some edge cases for like zoos and scientific study or museums and such
Why can't we do both? Especially species wiped out by people (Mammoth, Thylacine, Dodo bird, Carrier Pigeon, etc.)
Exactly.
Agree
No point. Many extinct species collapsed because their environments were destroyed too. Passenger pigeons have no woods to return to.
@@blackosprey2219 Replant them.
Bring back dinosaurs and animals pre-dating human activity? No.
Animals which used to have a place in the world but were wiped out by human activity? Great idea - if we can fit them back in and not use them as exhibits in protected, artificial environments.
I mean, look how people freak out at the reality of Beyond Burgers and Impossible Beef! 😺
Dodos - yes.
Dinos - please, no.
Have We learned nothing from Jurassic Park/World!?
Shuddup I want dinosaurs 😭
I want the dodo to come back so freaking bad
same
Same, I read they taste great.
That was my first thought, Bring back the 🦤
And hopefully, we can. 🙂
Y? I want the sabretooth... I mean the CAVELION EXTINCT 200 OR 500 YEARS AGO IN AMERICA
Bring them all back. Look at what wolves did to Yellow Stone, it brought an entire ecosystem back.
YES
YEAH & NOW, WOLVES ARE HUNTING IN 40 UO TO 100 PLUS PACKS OF COURSE NOW THERE IS A PROBLEM AS THEY MAY POSSIBLY ENIALTE OTHER SPECIES , THEY ARE EVOLVING AFTER HUMAN INTERVENTION THANKFULLY A CLOSE WATCH IS TRANSPIRING
All we want are Mammoths and T-Rex
lol
You forgot the saber tooth and the cave lions
I want Neanderthals back
Just re-introduce the Grizzly bear into sanctuary cities. that'll thin out some problems.
Trex!!! 😂😂
All the animals we could potentially de-extinct went extinct so recently they coexisted with most living species; they would NOT be invasive if brought back and reintroduced.
You're absolutely right. It's our responsibility to try and bring them back if we can, we artificially caused their demises.
@@JoshTrager-j9gyet human instinct would say to continue to hunt them to extinction only to bring them back. Human greed and ignorance knows no bound. The idea is extremely interesting but too many what ifs. Some things you shouldn’t mess with rather be a valuable lesson
@@TheLivingLife9 Then those individuals who are ruled by their basal "human instincts" and who embrace ignorance and greed, will all be thrown in prison. Simple as that.
Smallpox
@@BCUGhh bring those people back :P
Yes, but it depends on the species. If their natural habitat is wiped out, then it's foolish to try.
Restore the habitat too. It can be done. It's just a matter of if we want.
Preserving existing and restoring extinct animals are both needed for scientific purposes.
For science, maybe; but what about wider society beyond the selfish desires of scientists?
We're on the same page 😁
Ah you fools, wait till they try this with humans and start to tell you the weaker ones aren't weren't the limited resources on earth and people like you will agree.
I am so ambivalent on this issue. On one hand it would be so cool to see some of these extinct animals alive. On the other hand, as what’s-his-face said in “Jurassic Park,” “Nature chose these creatures for extinction,” so bringing them back could be construed a “violation of nature.” I think it’s inevitable that it happens but it doesn’t mean it’s a smart thing to do because there are unintended consequences that can’t be foreseen.
We, humans, made this species go extinct in the blink of an eye. They were not "natural" extinctions.
Why is nobody addressing the issue of how any of these extinct species can be taught how to behave as such, instincts only go so far.
It would be natural from what they say create and release, plus it's in the dna since they are only exchanging certain aspects of the original egg donors dna, so it should not impact natural instincts I'm just a pothead
I don't think anyone is teaching any species anything at the moment. If you are talking about how an extinct species is going to fit with the current existent, that is different.
@ well the animals parents would be the ones to teach them how and where to survive.
It's debatable; on one hand many avians and reptiles are essentially ready-to-go the second they hatch. I don't see a cloned Dodo for instance struggling on how to Dodo. A Mammoth on the other hand is essentially a furry elephant - a species that spends years if not decades learning from its extended family. They'd need to somehow develop a kind of surrogate teacher able to withstand the same conditions as a Mammoth without already having a Mammoth.
@@ericbotondbatternay8452exactly the one thing cloned animals don’t have.
"Species extinction date" is just a point in time like any other. While the longer a species has been extinct, the more complex its reintroduction might be, extinction itself is not a clear-cut boundary - so why would there even be a reason to treat it as an absolute dividing line. Viewing it that way is more of a superstition than a rational argument.
Some argue that we have a moral responsibility to bring back species we drove to extinction, but that’s not really my concern.
There are practical reasons beyond morality that could justify it, such as ecological benefits. If the species’ original habitat still exists and functions similarly to how it did before, then bringing it back could make sense. Likewise, if the species played a crucial role in an ecosystem that could still benefit from its presence, reintroducing it might be valuable. In some cases, extinct species-or similar substitutes-could help restore ecosystems, improve biodiversity, or even act as carbon sinks. For example, woolly mammoths could help slow permafrost thaw and promote grassland growth.
Another common argument against de-extinction is that "the time is right" (for death). But this "reasoning" is more superstition or quasi-religious thinking than anything scientific. Even then, religiously it may "make some sense" when applied to individuals than species. At least in the religious I know there is little focus on species as a whole, the all-mighty sees individuals, why would the time for a species as a whole be right?
So, the real question is whether we can reintroduce them in a way that benefits ecosystems, the environment, or even ourselves.
It’s also worth noting that not all extinctions happened in some distant, prehistoric past. When some mammoths disappeared, humans were already building pyramids. Grouping all extinct animals with dinosaurs oversimplifies the scale of time and ignores the varying contexts of extinction events.
So, should we bring back extinct species? It depends. If it benefits the environment, biodiversity, or even humanity - while being feasible and controlled - then probably yes. If not, then no.
Can it, nerd.
@@golden1391nah he’s onto something
Humans didn't build pyrmadids
Awesome documentary! Thank you for sharing out mission 🧬🦣🦤🐅
This all very cool, but I definitely prefer preserving extant species over bringing back fully extinct ones
With 4% of mammals remaining in the wild its a bit late for that! Next thing they will be telling us they cant bring back the dead lol
only selected extinct ones, not those who are geologically far extinct, Mammoths who are relatively young extinct and dodobirds, their niches arent still filled by a new animal yet which means they are still keystone species on their abandoned environment. In this fact the environment they abandoned still suffer in their absence up until now. While far extinct animals is a cool idea to be revived its more challenging and impractical since other animal probably fill their niches.
not extinct if we can bring them back....
I agree and this technology isn't wholly useless in that avenue either. A lot of the species we've 'saved' we've only rather delayed extinction; their populations are too small to be sustainable and often suffer from a genetic bottleneck (e.g. New Zealand's Kakapo, USA's Black-Footed Ferret). These species will eventually dwindle to nothing without an increase in genetic diversity. Cloned specimens using dead individuals could bridge this gap and feed new blood into their genepools.
In nature when a species gets extinct then many more new species come into existence. Only Change is permanent in nature.
I honestly don't know if we should, but I do know that the idea is way more exciting than bringing people to Mars.
Seriously... This and exploring our oceans in search of all the unknown species that exist now on our planet. That blows my mind! We're going so far away in search for life... Yet we have so much life HERE that we're unaware of 🤯
I find going to mars cooler, obviously restoring extinct species is more important
@@Paulos12-21 Sending excessive population to Mars is essential for restoring species... 🤣 Species keep getting extinct because too many humans occupying their habitat.
@@Paulos12-21 I was gonna agree with you but then I realise that we deadass haven’t even built a permanent base on the moon yet. I think that right there is the coolest thing we could do right now, but unfortunately haven’t.
@ Well kind of, its less us occupying there territory ( although that is true ) its more us ruining there territory than occupying it. but yeah going to mars might free up alot of space on earth, and climate change doesnt really matter on mars like it does on earth.
No, we should look after the endangered species we have now
theres always a "Karen" in every research. thats why we dont finish one thing to another.
your not erasing old sins your creating new ones that u have no control of in the future. everything is already a mess.
Would you spent 1 million on a hospice patient, or would you rather spend the money to provide care for patients in a hospital.
Even if you managed to bring them back, what good does it do if humans just drive them to extinction again in 50 years
NO! Humans have been making thousands of species disappear so why not take the time to prevent that instead of bringing back any animal??
I want species from the ice age and recent species from our timeline from the 1600s - 2000s as a Native American and native Polynesian I want our ecosystems restored for the future of our people I want young children to see de extinct species their ancestors saw and how they can contribute to preservation of these species
Mammoth is #1 choice! Eats grass, looks friendly, lots of wool, etc..And #2 choice is Dodo bird, looks too cute 😊
Nothing extinct should be brought back to life until the full impact on the current food chain is well understood. If we can not understand and control invasive species, we certainly should not be messing with the food chain. Extinction happens for a reason.
The reason can be our fault, in which case we are INCLINED to bring them back
If the Asian elephant is losing its habitat, what makes us think that the mammoths Will survive ?
Unc you should think about this more thoughtfully before making an assumption, this entire comment makes zero sense.
Of all the possible apocalyptic scenarios, I prefer going out by an evolved pack of prehistoric predators.
Absolutely:)
currently we are already being wiped out by prehistoric predators,, its just they are known as republicans and democrats
The last mammoth died only 4,000 years ago. Please resurect them 😢.
Should we? Answer: yes, if they still fit in their original ecosystems. If not, maybe for educating people about human-caused extinctions in zoos. A good idea anyway.
Yes. They deserve the planet more than we do.
I hate when they say you are playing god! Smh let the scientists do there job! We wasn’t playing god when man drove them to extinction right! ?? Okay then 🤷🏿♂️
IKR. Humans have always been playing God, it's nothing new. We literally wiped whole species off the face of the earth, what do people think that was?
Fr people who say that are just halting progress in technology.
@ frfr man
We can't and could not even protect the species we have and have had recently seen extinct, even by our own hands.. so.. I just don't know how this is a good idea. Looking back at the economical and ecological disasters brought on by introducing invasive species makes me hesitant to embrace this idea. We're not historically very good at playing "God."
Over a million species on the brink of extinction and this is what we are doing?? I find it deeply deeply disturbing
All those species on the brink of extinction are being helped to thrive by foundations and animal organizations. If we had the opportunity to bring back species that were exterminated by humans, we should definitely undertake it.
@@carlcostahumans can’t create a soul and technology can’t even detect a soul at this point so whos in the drivers seat of frankensteins monster?
No thats what they’re doing. WE are watching yt
a million species on the brink of extinction actually sounds like a perfect practical use case for being able to bring back extinct species. it should be clear by now that as long as capitalism is allowed to murder the planet for profit conservation is not going to happen
I'm ok with bringing back the recently extinct especially if it was artificially induced by poaching or culling by humans. However, bringing back animals that have been extinct for thousands or millions of years ago is quite another level.
Just try to imagine a Real Jurassic Park!! Ticket sales would be Historic!
Animals that died off recently due to humans I think are reasonable candidates to bring back since they would still be alive in the worlds current state if humans didn’t over hunt them or destroy their habitat. Such examples are Great Auk, Stellar Sea Cow, Passenger Pigeon, Pyrenean Ibex, Tasmanian Tiger, Western Black Rhinoceros, Caribbean Monk Seal, Javan Tiger, Moa, Haast Eagle, ETC.
24:34 Claiming “We are not taking capital away from conservation, this is new money going into conservation” is complete bullshit, for sure there’s going to be a small percentage of new money going into this that wouldn’t have go into nature conservation otherwise (e.g. investment banks, venture capitals)
But the majority of the money being used to pay for the astronomical bill is coming from government fundings, as well as ordinary people who want to protect the environment, but find this much cooler than any existing conservation effort
BS as it is, however to bring in investment they need a Mammoth.. something most people are fascinated with.. at the sametime create gateway to new technology.
@ If there’s anything I learnt from Elizabeth Holmes and Sam Bankman-Fried, bring in investments aren’t hard, especially when already have the technology and proof of de-extinct
Why are we not restoring extinct tribes and cultures also😅
I want my T-Rex😊😮
No you don't. Better rethink that.
Do you want to be T-rex's food?
Why, to eat you?
Can one request a wife from the 20s?

This is an excellent documentary. i enjoyed it!
Thank you for watching and taking the time to comment!
Save the present species don't bring extinct back
Bring the gentleman species back please.
We will Not Stop Losing our Land and Marine Animals until we address All the Pollution in the Land and Water. Trash everywhere, plastic Bottles in the ocean, Islands of Trash and ships and companies dumping Toxic Waste.
Will the technology be used to bring humans back to life?
I think that there will be someone who can't resist cloning somebody, eventually. But I doubt if the clone will have the exact same personality as the original individual.
*Humans means Whites only ?*
We already have the technology to reproduce a human clone - we've had it since we first cloned sheep - it's really just a moral question over a practical one. Would a clone be considered the same person? What does that entail for things like crime or citizenship. Hence why cloning humans has been internationally recognized as a crime.
What year was this Documentary made?
There was no discussion about learned behaviors and nurturing of the young. Mammal offspring all survive in part due to learned behaviors-how to avoid danger, hunt and forage, relate to one another, and so forth. They need physical contact with the parent. Young animals need protection. Should the animals mature in a sanctuary system, how would they be prepared to survive in the wild? Habitat destruction is occurring at an alarming rate, so how would such a 'colossal' investment be protected? Would there not need to be protection in perpetuity of the environments into which the animals would be released? None of these questions were addressed, and all present obstacles to a successful outcome.
Shouldn't we focus to save the living endangered animals which is more important for the balane of biodiversity and ecosystem, already some people have caused lot of damage by introducing invasive species in not native places,
Of course we should!
Absolutely! 😤
Yes but few points:
-Only species that actually coexisted with H. Sapiens (for the last 55000 years)
-And in regards to megafauana... very selectively overtime and slowly
We should. The question is how?
Preserving present and endemic animals rather than reviving extinct species is like maintaining a well-functioning hospital instead of trying to resurrect patients who have already passed away. While the idea of bringing back the dead may seem fascinating, ensuring the survival of those who are still alive and vulnerable is far more practical and impactful. A thriving hospital saves countless lives every day, just as conservation efforts protect ecosystems and prevent further extinctions.
You forgot Canada. It’s not just Alaska and Siberia in Russia. In Canada, mammoth fossils have been found in Yukon, the Northwest Territories, British Columbia, Alberta, Saskatchewan, Manitoba and Ontario.
I support anything that increases the biodiversity on this planet. We have already done so much to bottleneck the biodiversity here on earth.. There is nothing more important than our ecosystems
Here’s hoping for new Northern White Rhinos being born in some surrogate Southern White Rhino Mothers. Maybe a dozen or so surrogate surrogate Southern White Rhino Mothers, & hopefully enough to produce some new Male & Female Northern White Rhinos that’ll stay with in the safety zone until their numbers are increased & when they’re big enough to live in the area of their ancestors.
25:13 that's title belongs to the Marsupial Lion (Thylacaleo Carnifex)
We cant even safely make a single change in human DNA, and now we think we can make thousands upon thousands of DNA changes to engineer the DNA of a Nicobar Pigeon into a Dodo's. I think it is wishful thinking.
We can't even produce synthetic eggs. We're closer to cloning mammals than we are to birds or reptiles.
But in regards to the practicalities we can 100% alter certain genomes with reliable results (e.g. coloration and bioluminescence) to such a degree that we've made vanity pets using it. KRISPR will likely increase the number of reliable points of entry we have -- the question is how many we'd need to create these species reliably.
Can they live in apartment complex’s? If not idk if it’s a good idea.
Do what ever it takes to save the.white.rhino
It’s like The Jurassic Park and The Terminator series never existed 😂😂
Sometimes there is a natural reason why species will go extinct, natural selection.
However, some species went extinct Unnaturally because of humans cause their demise.
If those animals could provide an environmental benefit. And if bringing them back will not disrupt the food chain, then resurrecting them from extinction should probably be done.
Any species that has been rendered extinct due to our actions we have an obligation to bring them back (if we can,) since we artificially caused their ends.
Wonderful view ♥️♥️♥️😍
Should you bring any being from their natural habitat to one where it has no natural predators and thus become an invasive species?
Thylacine’s de-extinction is a guilt feeling when you’ve done an irreversible incident that changed the course of Aussie’s wild outback…hope it’ll be a success…
I think it is a failed idea ..bcoz what's the point in just bringing one animal with zero genetic variation to life ...A very expensive excercise
Time's right, life must take its time and course by itself
Might as well bring back dinosaurs because it feels like humans are reverting back caveman😂😂🪨🦖🦕
Northern penguins
Tasmanian tigers
Woolly mammoth
Would all positively impact the environment.
Bringing extinct species back to life is a fascinating yet controversial idea. Does nature have space for them, or would we unintentionally disrupt ecosystems? An amazing and thought-provoking documentary! Thank you
We thank you for watching and taking the time to comment!
Restoration of spieces that could benefit the ecosystem and help the invoriment, to undo and heal from the disaster brought by humans,
Am very supportive of that.
I recently got pooped on by a seagull, imagine what it would be like with a group of Pterodactyls flying about! 😂
It would steal more than your chips that's for sure.
@@KevinN-df8eo ~ _baby screaming noises_ ~
Could’ve sworn there was an entire movie series about this very concept
First we need to focus on saving current animals from extinction..
Just because we can, doesn't mean we should
Absolutely not. Just because something can be done doesn't mean it should.
Agree. Why Spend resources on this vanity while extant species are going extinct at a massive rate?
Yeah, that solves everything. Thanks for your contribution.
If we don't do it, someone else will. Life finds a way...
If you watched the documentary, you'd be aware that 58,000 species 16:01 are lost every year. That is an insane number. Diversity is what makes our world liveable, and we don't know the future impacts of the losses. One loss can have a precipitous effect on other species. If we can save or revive some species we may be able to save ourselves from the fallout of the ongoing mass extinction. Of course, this also requires eliminating pollution and environmental preservation so fewer species are lost in the first place. This clickbait "should" business from the title might certainly apply to non-human related extinctions of the distant past, but will be necessary for our continuing survival and the survival of the living planet we seek to destroy.
just because theres a catchy slogan doesnt mean we shouldnt do it, also thoughl. have any actual objections?
A wonderful documentary from DW ❤❤❤. This is DW speciality that picks up very diverse subjects and explains them eloquently for viewers. THANKS DW.
One must hope that scientists will also make efforts to reverse the effects of climate change.
Climate change is due to over own actions and putting at risk of countless lives.
Thanks for watching and taking the time to comment.
We need to focus on saving rhinos before we ever bring back a mammoth or dinosaur!
They made a movie about this and it didn’t go too well. I’m sure you know it, Jurassic Park
We are destroying the environment mammoths would need to live.
Bringing back mammoths would actually help environment preservation as they were a key stone species. they would help slow down Siberian environmental destruction and global warming.
The environment of the mamoths was dissappearing long before humans which is why they died out and the last mammoths were stranded on wrangel island suffering a genetic collapse. Mammoths don't exist in forest territories but wide grasslands...
@@Kennon959 no you have the Domino effect reversed. Humans hunted mammoths to extinction, once the mammoths were gone the whole Siberian grassland ecosystem collapsed and all it's megafuna because mammoths trample and knock over trees to eat their top foliage and spreed grasslands for other large grazers. Same as in Africa with African elephants it's literally why elephants have tusks. As soon as mammoths disappeared the whole environment changed. The same thing happened to north America once humans entered and exterminated the mammoths. Wrangel island mammoths made it so long because humans didn't get there sooner. they unfortunately died because their base population was so small after thousands of years of inbreeding the generic material was so mutated they like biologically combusted. Mammoths made the environment not the other way around.
Bringing back the mammoths would hypothetically recreate the Siberian grassland environment of the last ice age. It would also hypothetically cool the earth or at least slow down it's warming. More grassland in Siberia would create colder winters because of the lack of boundaries of cold arctic wind coming down over the flat open grass fields. It would also increase the albino effect (sun bouncing of white snow on flat land) and the soil would then absorb less UV or sun heat which means less warmth overall. The third thing is it would slow down Siberian earth thawing which is releasing the earth's highest amount of monoxide (greenhouse gas's).
Hope all the dinosaur come back to their life 😢 , i really missed them ❤
This is the extension of human heroism, which might be questionable. I think people should stop playing "God" since we have already gone so far. Human don't have do backtracking if the root of the extinction problem resolves.
It would be really cool to bring these species back, but the thing is, we don't look after the animals (and even our own species) that currently are alive.
Prioritise the health of the current habitation first.
The argument of “shouldn’t the money be spent elsewhere” falls flat when you find out how much money the us government is wasting.
No, but, that never stopped us before
I think cloning rhinos or other animals that died because of us in the last 700 years , im still on the fence about mamuths but i think its worth a shot IF we can get the full mamuth genome im more concerned aboutgeneticaly making tem with elephant dna and the most important thing is that e have to make sure the revived animals actualy have living spaces in the wild if we cant prevent them from dieng out again that all of this is pointles ...
58,000 species of what go extinct? That is a wild number. I would like a list of what we are talking about.
Fascinating area but I feel like a lot of the points are moot since we don't have a living breathing specimen of whatever animal they're trying to bring back.
As far as I know, there has been one example of de-extinction on record. The Iberian Ibex. It was brought back for less than a few hours before the lamb died of respiratory failure. This was back in 2003 so obviously technology has changed since then.
This vedio was released 1 day after jurrasic World trailer 🤔
Let's save the white rhino!
There’s only hope. I want are diplodocus, eurypterids, arthropleura, anomalocaris, and even meganeura.
Like what Doc The Lone Dinosaur said “Change what you can, accept what you can’t.”
Why aren’t you guys broadcasting to Africa on free satellite TV anymore? This used to be my best channel by far
That’s really sad to take away the baby rhino from the surrogate mother.
A kick start may be a gamechanger.
Love the documentaries ❤❤❤
Watch it first
Just to be the first one to comment you dont even take time to watch and appreciate the effort put into making the documentary there no prize to win by being the first one to comment on the video
Thanks for watching!
@@videoschannel1416 sorry, I didn't mean this video I meant all the videos.
Mankind playing God? No thank you. We need to learn how to conserve life and protect endangered species. It is not our place to choose what will live and what will die.
Sad... 😢
That rhino 😢
I think we should invest in protecting what we have left.
When they introduced wolves back into parts of the US in the 90s they didnt realise what would happen. Where there was just tiny shrubs they showed the difference after introducing them and the whole area was really lush with all different types of fauna. They said the habitats that have been allowed to develop because of the wolves controlling the elk populations supports far more biodiversity than any area without wolves...
I'm my humble opinion. We should NOT bring back the woolly mammoth. Why? Feel free to laugh, but I believe the woolly mammoth is still alive because of the number of sightings in Alaska, Canada, and Siberia.
Yes bring back honest moral politicians.
To far back, not possible
next recreating the Ice Age
Heck yeah, im all for it. This will be a start. The possibility are endless repopulate the species that are soon to be extinct
Edit the only thing i hate those animals will be used as a display in a zoo or in some wealthy person home
