- Dig into how scientists are attempting to revive the functionally extinct northern white rhino through artificial reproduction.
--
In the savannahs of Kenya, two female northern white rhinos, Nájin and Fatu, munch contentedly on grass. They are the last two known northern white rhinos left on Earth. Their species is functionally extinct- without a male, they can’t reproduce. And yet, there’s still hope to revive the northern white rhino. How can that be? Jan Stejskal dives into the science of reviving a dying species.

Have you heard "The seed" by Aurora? The song was inspired by the quote.
Update was of today: 12 good embryos, there's recently been a sterilized southern male introduced to some potential southern mothers to hopefully identify them better. Najin, now age 32 has been retired from collection due to age and ongoing health problems. Fatu is still going strong! They plan that within 3 years to deliver the first calf and have a wider population of northerns in a decade.

@Practize13 Gamezone He clearly said "leave the nature alone" but you can see what we have done , so we should take the move at least to balance it. If possible...
If you count me in you are mistaken. We didn't do it only the rich did it.
This isn’t Jurassic Park, it is humanity and not nature that has directly contributed to the extinction of many species of animals, who otherwise would have continued on existing within their natural habitat. If we can develop the method for artificially reviving those species then I think it’s our responsibility to do so.
well yes, when it comes to this topic there's some concern about things like what happened in those. movies would happen, but that's possible with dinosaurs, I wonder if it's the same for other animals
Please see my post. Genetic tech on a few rhinos is not the answer by a long shot. Poaching will continue
@Ahmed Jones You forgot to stop the source of the pollution. Or else, we're screwed either way.
In fairness to Jurassic park, they give Ian Malcolm this exact line of reasoning. Hammond tries to compare the endangered condors to the dinos, and Malcolm immediately replies with the "humans are causing that" line.
@Ahmed Jones because we don't know if at that point it'll be possible anymore. If the other rhinos go extinct as well, there will be no surrogates and science isn't as easy as it is made out to be in movies.

Humans arent the first animals to cause a mass extinction event.
"Do we have a responsibility to try to bring species back from the brink, especially when human actions brought them there in the first place?" Well, if people would have cared more about how not to bring them there for last several decades, it'd saved us an effort of asking this question now. But because they didn't, yeah, we have such a responsibility cause the situation went too far to improve by itself.
As a South African,I'm very sad about these animals
@INERT hello
@Yiming Peng Rhino horns are used as an afrodesiac in East Asia. There's no scientific evidence that it is so that's where the discrepancy lies. There has been efforts to legalise the trade in Rhino horns in South Africa to allow for safe harvesting of the horns to prevent poaching. I'm not sure if it's worked though. Hope that helps
@Yiming Peng i didn't say it was. I think was a blame game
Yiming Peng It’s not, but I thought there was a big demand for ivory in China in the past.
@INERT not only China. Eastern Asia believed it had medicinal properties but the rest of the world saw it as expensive, fancy material. They'd sell sculptures and stuff out of ivory for a high price

“Extinction is the rule. Survival is the exception.”
― Carl Sagan
So if I'm right you're saying that all the species will eventually die or evolution will make a different species, and surviving is the during in the transition?
@@spadervenon9152 yeah sort of I guess. I think there are only few species that've survived till no since they formed.
Yeah, no.

Extinction does happen, but the extinction that we are cause is going at a fast rate and enough time for no species to take over. Just because extinction happens by nature doesn’t give us an excuse to make it happen.
Marcelo Sanches
Don’t listen to that person. Extinction does happen and new species come in, but we cause that stuff to happen at a fast rate. It would million of years for a new niche. Don’t excuse the fact that we causing extinction.
The way you presented the closing graphics are so awesome,I don't know if we are enough to appreciate you guys

Conservation must begin while there's still a male and female member of the species left. You cant revive extinct species, unless you had started conservation before they went extinct
Im so glad that there are people out there that are doing everything possible for these animals😔✊
Amazing video! Well done, Ted Ed. You all are awesome.
Yes! I have been waiting for a video like this for a long time!
One such species of tortoise which were declared Extinct were somehow found in a temple in India in very less numbers but now have been revived and they moved from extinct to critically endangered.
Wow early to appreciate my love of Ted-Ed

Hey guys if you like space videos then do visit my channel pls once it's an interesting channel about space pls ...🙏🙏
Can you imagine how much cheaper and easier it would have been to just prevent poaching (say, by paying people not to poach) than what we have to do now? And this is all ongoing with other species, with threats ranging from poaching to pollution to climate change. Prevention is definitely the way to go
Ok, but who is going to pay people notmto poach, then everyone who has never poached is going to ask for the same prize and every world government will have no money, it isn't that simple.
@@millerkidsmiller3733 for one easy example you could pay the people surrounding parks or placed with protected animals to monitor the animals or tend the land, or creating other financial incentives (like through tourism) to offset the financial benefits of poaching and create a direct link between the wellbeing and population of the animals and the wellbeing of the communities around them
@@13ccasto sounds good
This is amazing. Keep up the great work
We should try to bring animals back from being extinct only if humans were the reason that they are going to be extinct, but if natural selection is the reason they will go extinct, bringing them back won’t help because they will die anyways if we leave them in nature, unless we have an advanced technology to edit their genes for them to be more likely to survive such as giving them extra strength to run, etc.
What about species that are at the brink of extinction due to invasive species brought there due to human activity?
But shouldn’t we consider the fact that we are part of nature, and so, if they became extinct because they cannot survive and adapt to the environment dominated by humans, wouldn’t that be natural selection as well?
Mario Toller we can’t kill the invasive species in that particular area, so that’s not an option, so the only way is to move those species to another area where they will thrive and survive, if we can’t do that then technically that is natural selection and we should keep those animals alive only in zoos and as pets? Just like how we are doing with dogs and cats
Uh Huh yes you are right, if animals can’t survive an urban way of life, and they go extinct then that is technically speaking natural selection, but people get mad at other people just for “existing” have you met those people that are like “humans are cancer on this earth” the type that hate themselves because they pose a threat to other animal’s lives? Well I don’t like those people because they don’t realize we are nature, and we were naturally selected by nature to be more intelligent and that’s what intelligent beings do, survive.
Frans Tammo
Yes, I become a bit irritated too, and it happens more often than not. Which makes me think, who do they think we and themselves are? Asteroids?
But, I do understand something about them, some may just be because they absolutely adore those other species and is extremely frustrated by a narrow view where humans are the sole cause of those other species’ sufferings and impending extinct (if they weren’t extinct already). Yes yes, humans are notoriously greedy but that trait isn’t inherent, or at least I don’t think so. And there are people who are just... violent and harmful to everyone and everything.
Edit: Such as poachers, not all are greedy, selfish and whatever. Not all kill only to feel happy, or to be famed for their ‘trophies’. I don’t know every poacher, I don’t know any. But I do think there are some who kill only to sustain themselves and live in some kind of a poor society. Considering how many people there are, and how different each person is.
How can it be considered as a 'maybe responsibility' when it's obviously a debt we have to pay?
Happy to know that species preservation is happening in some part of the world even in this difficult times.
The music in the background along with the "do we have responsibility line" gave me goosebumps
female rhino : i would only date you if u where the last rhino on earth.
male rhino : is that a ChAlLeNgE?
They live in my hometown. They are such graceful animals. Sad to see that this is the case.
I love these videos. Literally these are my new topics of conversation
Your Videos are very helpful .

I've never seen a rhino. I suppose all of them come with a hovering compass near their horns
Really well done video, and I think it's great that we as humans, despite our mistakes, rarely lose hope. However, I have a question regarding the long-term nature of such a project. If all the rhinos come from the same eggs, doesn't that minimize the gene pool a lot? Does that have any effect on the health of the next generation? For example if two rhino childs with the same grandmother pair up?
Btw I was never the best in biology..
I love the narrator of the ted ed i don't know how. its just light up my mind
Soo glad u found dis channel
Humans: What's left to do?
Other Humans: Make Animals Extinct.
Scientists: Yes, and bringing them back again.
Good news, scientists have successfully extracted eggs from a southern white rhino in August 18 2020. So we are making very good progress
Thank you for enlightening me and spreading knowledge!
I'm currently researching about cloning extinct animals for my biology project in college, this video definitely showed up just in time. Thanks TedEd.
This video is amazing. Although as a student of pathology, I have one major concern. If the blood cells of both species have even 1 different antigen, then the surrogate's immunesystem may attack the developing embryo at any stage during the pregnancy! Maybe the researchers should see if the northern species' blood is producing any reaction in the southern surrogates. ( i.e. if injecting the blood of the northern species into the blood of any female southern white rhino is resulting in the formation of any abnormal antibodies).
Good point!
It can be done by extracting the nucleus from a preserved cell from the extinct species and swapping it into an egg, without a nucleus, of that species' nearest living relative.👍
Dolly the sheep basically. Same principle
ted ed l never get bored by your art styles and your content
I really needed to watch this video
Very early for the first time.😅
I don't know why, but this saddened me a lot.☹️
But I guess because of the poaching and also other ways of pushing creatures into extinction. We should really let them live in peace.

This topic is so very close to my heart I believe we Owe it to these wonderful Animals and Mammals to help bring them back Not Only that But to help this from happening !! May God bless you you his cause And these dear dear Animals !!
I'm Czech and I must say that the pronunciation of "Dvůr Králové" is incredibly funny. I love it when foreigners try to pronounce Czech words.
I love it how you put those moral questions at the end.
I think we should save them, especially because it were humans who brought them on the brick of extinction in the first place.
We're nature as well, only we are conscious and rational creatures, and in my opinion being conscious and rational creates a responsibility for those who aren't, in tis case rhinos.
