Could you grow rhino horn or elephant tusk in a lab? To save the animals. How about using the crispr technique to remove the Gene for horns and tusks.
If we have re-populate some species via cloning, we will probably wave to print the embryos, we can print dna so this is the next logical step, but also do we really need every sub-species preserved as if in amber; especially if the sub-species of that species are interfertile
This video is shortsighted. This isn't about "restoring the ecosystem in our lifetime". But, in a few hundred years, when Von Neumann machines are building mega-structures in space, we will be able to create land as fast as we use it up, and at that point, we will be able to set aside land for creatures.
Ideally, we should have been doing this 30 years ago, instead of messing around with bio-domes and other nonsense.
We are running out of time. In 2100, there won't BE any f7c7ing "tigers" and "rhinos" to sample.
Start archiving NOW! Don't be the cancer. Be the cure.
I'm starting a GoFundMe to fund my own cloning. Future generations need me.

Scrolled down just to look for this comment
Shut up and take my money.

You fought in the clone wars!?
Can we acknowledge once more how badly Pandas were screwed by evolution?
How so??
My point is, why don't we let natural selection do it's thing. Yeah I know there are poachers and stuff, but even without them they are pretty useless animals. They doesn't want to mate, they eat low energy food, despite the fact that they can eat other things as well. Instead of wasting millions of dollars to protect them, just let them go extinct
@@microska2656 they make alot of money
we should endanger poachers instead
That usually is a result of job opportunities and live chances, connected to local education and self sustainability... Aka expensive enough not to be done in the USA... Or somebody confused education and military budgets.
UltraSoulHero xD
People need to make a living somehow
@@hoodedferret you are comparing animals to humans. We are a dominant species think of that instead of comparing poachers and hunters to mercenaries. That's entirely different.
@@SolarCasanova 1, technically a soldier/murderer is dominant to the person they are gunning down so i'm not sure what your argument is 2, dominance only exists in a world where there are things to be dominant over, ergo if you gun down the animals you are dominant over, what meaning does dominance hold then?
I've done of lots of research on this as part of my degree and the main knock back is that there isn't a wild left. Even if you could increase numbers and avoid genetic issues, cloned individuals don't live as long as they have "old" dna.
The debate is basically the same as the debate for zoos: yes, it's great to build back up systems but what will really savr lives is ensuring these individuals have a safe space that meets their needs, which is something that is severely lacking at this point in time.
Space Colonization would tackle human population, dwindling resources AND endangered animals
Three birds with one rocket!
I like the idea of making stem cells turn into sperm & eggs, as it slightly increases the genetic diversity compared to cloning.
This is not even going into how to properly raise a wild clone animal. Raising such a creature in captivity would make it unable to be released in the wild, and extinct species have parenting requirements no longer available at all. There are likely even more issues we haven't even discussed.
@Sassy The Sasquatch For some species that may work, but there are many whose closest relatives live in completely different environments. Mammoths, for example, would not get on well where elephants live, and elephants would struggle to teach a mammoth to survive. In addition, proper fear of the local predators also needs to be taught.
They should make a movie about cloning dinosaurs
I like how they have to add in, “to save them” like no we ain’t cloning them for fun hahaha
*Warning: Do not clone yourself*
You can't tell me what to do
MJ did it
clones can buy us time, but that's as far as they can carry us
Then there would be evil twin pandas.
Because biodiversity :)
Richard Powell serious question here. I see how cloning doesn’t help with biodiversity. This is even a reason why if a very small group of the animal is all that’s left can be difficult to bring back that species from extinction. With that info, how does a new species form? Wouldn’t it only start with 1 or 2 individuals of the species? The biodiversity would be terrible for a long time right? Surely I’m missing something or misunderstanding
Because money.
@@illusion116 because in nature a new species doesn't just pop into existence. They mutate in tiny ways, breed with unmutated animals, pass those mutations on, again and again until eventually the animals in question are recognised as two different species. It'll take so much time for a new species to diverge that there's no issue with biodiversity because they can still mate with species A until their numbers grow enough or enough changes happen that they are distinct enough to begin to seek out mates like themselves, eventually culminating in species B.
I think you mean genetic diversity
@@illusion116 I think he meant genetic diversity.
I heart Hank ! You got me through chemistry without buying a book .
I’ll get a egg from a rhino just hold my beer
Why can’t the conditions in a womb be simulated in a glass jar? Make it happen. That let’s engineer clones that are genetically superior.
Can you stick the DNA in high radiation areas to increase mutations to hopefully force genetic diversity?
This is how we got the first 'artificial' variations! Gardens were systematically exposed to radiation, and any useful mutations were bred into future generations!
or use CRISPR
Most of those cells will start being cancerous very fast. Or just die.
It's a possibility if you want to breed flowers and have a LOT of time & samples. But doing that to animals you're most likely just creating a lot of cancerous disabled animals that won't have a long or great life
Possibly but the vast majority would just become cancerous
What about the animals around Chernobyl? Those ones didn't seem to be vastly physically deformed or cancerous. Well according to what I've seen anyway. Not that I went there in person. Well that's what the internet says... And we all know how reliable the internet is.
Even ignoring the fact that cloning endangered animals doesn't solve the problem of why there're endangered in the first place, why would you even try to clone them if you could have a conventional breeding program? I mean like it was said in the video, you still need a surrogate mother. So instead of collecting DNA and doing all the complicated science stuff, you could just pick two specimen and let them do the thing. Even in case the species is a bit picky when it comes to breeding in captivity like pandas normal in vitro fertilization is probably much cheaper and easier.
I don't see any benefit of cloning compared to normal breeding.
Because like the white rhino you may only have one left. Or did that one die already? hmm... Because science. Honestly. Because science.
@Adequate Bros. I can't help it and read the last three words of your comment in Ken Watanabes voice....
In theory, say you have a species of tiger with very few individuals left and a easy-ish method of extracting and cloning their eggs and fertilising them. Now you're not necessarily restricted to the individuals of only that species to work with. You could probably implant the eggs into another closely related species of tiger who could then carry them to term. Then you have many more individuals to work with, since you're not necessarily limited to the wombs of the individuals of the one species.
Instead of a female carrying a single litter fertilised by a single male at a time and thereby passing on only his and her genes to the next generation, you can have her eggs in multiple females and have them fertilised by way more males then she could naturally get impregnated by and all of that in a relatively short period of time. The next generation might only have 2-3 cubs if she only gets pregnant herself, but if there is a method to clone her eggs anything close to "Brave New World"-like, there might be dozens of cubs in a litter, spread out over multiple surrogate females of a different species.
@@HerrMisterTheo Everything you say is right, but the same thing should work with in-vitro fertilization, right? Cloning means you take DNA of a specimen and inject it in an egg cell and you get an embryo. With in-vitro fertilization you also get an embryo. Are cloned embryos easier to implant into another species than normal ones? I am far from being an expert, but I feel like the opposite is true.
I see where cloning would be necessary, when there are only females or only males left, or you only have DNA from dead tissue or in similar cases.
Clones. The one thing that can answer everything! Why does that person carry a dictionary everywhere? Because the clone made her do it. When was the Boston Tea Party? Ask the clone. Why is SciShow so awesome? Because they talk about clones!
Save their habitats, save the species.
End poaching for profit.
If only it was so simple. Most often poaching occurs because some culture is under the impression that the (insert endangered species body part here) will enhance their sexual prowess or provide a miracle cure. Targeting the poachers is not going to fix this problem. A lot of the poachers are just trying to provide for their families. If we can manage to remove these superstitions then poaching will no longer be lucrative. Habitat loss is even more complicated. While a lot of endangered species are put into these dire circumstances by mankind, some are just not worth the effort of saving because there are reasons other than mankind that they are endangered. Some things, no matter how beautiful, are not meant to be.
TheWraithkrown - Totally agree. I didn’t have the time previously to make a longer, more meaningful comment.
@@ThePenguin369 how many have you killed, edgy soy boy?
@@TykoBrian7 im female but thnx
It seems cloning can be used on animals which can breed fast, die young and are very peristant and resistant at the sane time and are very common.
Right, so the ones in zero danger of going extinct, like goldfish.
a cow named Bessie...
USACO intensifies
Oh I love this show. Thanks!
hank always gets the good topics lol
Maybe it's time to give out hunting passes for poachers. For each 5 poach you tag and bag you get $1000. But don't forget they fight back.
Hmm, I was always wondering what Rob Chapman does in "Centered and One" at the beginning, and how he does it.
hey, I recently saw an episode about age associated diseases and that even without them we wouldn't live longer, where ca i find it?
I was thinking about this yesterday weirdly enough
Apparently it's so dangerous in some parts of Africa, they won't ALLOW you into some naational parks without an ARMED guard with a FULLY AUTOMATIC rifle to protect you from poachers.
Not mentioned here: In many cases an alternative to cloning is breeding. It's not much harder to factory-farm lions and tigers than to factory-farm cows and pigs..The problem here is that you might end up with large numbers of huge predators that know absoultely nothing about how to hunt, and that tends to end badly.
You should look into ips cells. They've already been able to clone mouse using simple body cells
"You can't just do this in a petri dish."
...why not?
Well, not at least with mammals. :/
This helps explain some Metal Gear Solid plot stuff.
SSSNNNNNAAAAKKKKEE!!!
Good point.
I look at that Gaur and think “there’s a lot of meat in there”. And now we know why it’s endangered.
let's clone Hank, just in case!
Hank Green is my favorite 😊
Dogs, cats, even monkeys have been cloned.. i like how you left humans out
Thanks to skillshare! Always thanks to skillshare
Is there any good artificial womb tech out there?
Either developed or in development?
I for one look forward to the day Humanity can create its own species. That will be some next level art. I want a Blue cat.
Fact: all cows are named Bessie. (SciShow, 2018)
Okay next on the list is man made eggs/Cloning chamber XD
Yeh, and what surrogate is going to carry a Rhino - an Abrams tank? ;-)
Good one
Can they bring back the mammoth?
Yes.
FFS 10,000 elephants were poached in the last 3 years, First let's preserve elephants!
No
They can. But the habitat with which the mammoth lives in is no longer there so the mammoths would go extinct again immediately. Unfortunately they lived during an ice age and they're full of hair to keep them warm. And we have global warming. They will be too hot. Also the food that they ate has gone extinct. I'm sure that they could find something else to eat but the fact that an animal as largest them has a very difficult time expelling heat hands are covered in hair to keep heat in would make it very difficult for them to survive. The only habitat they would be able to keep a proper body temperature in would be the Arctic which is rapidly shrinking and also doesn't have enough food for them to sustain the body mass. What's the point of bringing animal back from extinction only for it not to be able to survive in the current world that it's in.
The best mammal to bring back would be the thylacine. it went extinct so recently that its habitat is still feasible. Then again the dingo sort of took that niche over so it would have to compete with the dingo. They could try the dodo if they have any surviving samples but that would be highly unlikely because it's probable that there are cats and dogs now and probably mice and rats on the islands that they were on and those are extremely able predators for a flightless bird like that. Like sticking fox in a chicken coop. Just a free-for-all.
Can't crispr fix the genetic variation problem?
isaac renaud no
Rip Dolly,you were the first clone
Cloning could help as you pointed out bring back genetic diversity by taking DNA from dead specimens, It could also be one of the only ways of brining back traits from extinct animals.
If we developed the technology to make a artificial womb which has been tested on a underdeveloped goat.
Also make egg cells and sperm cells the technique could be abit cheaper and less risky.
I'm a bit slow but are you saying - you need to break some eggs in order to make a clone?
And here I thought animals interbred
“You can’t just do this in a petri dish”
Yeah cause I thought you could just stick some DNA in a small dish & a day later you have a big ass animal baby
Waiting for Muscle Hank's funny comment
More Hanks
As long as the wild tiger population continues to grow, and we are fighting poachers I am happy... however cloned tiger definitely sound awesome
Because the cloning machine tab out of batteries
Cloning endangered animals isn't as easy as you might think, and it won't really increase their numbers. To clone something, you typically need more than just some DNA from the original creature. You also need an egg cell to put that DNA into to create an embryo. And you need to know a lot about that animal's reproductive biology, like when they ovulate. If you want to make a baby goat from an egg from a cow, you need to know a lot about the animal's reproductive biology.
You also need lots of eggs and lots of healthy female animals. For some species, like tigers or rhinos, there may not be enough female animals to work with. The good news is that there are ways to cheat and use eggs or mothers from more common, closely related species. Cloning might one day be able to make a lot of eggs from lots of different animals, but it's still in the very early stages and the process will likely need to be customized for each animal. Even if we could clone any animal we wanted, you could still end up with a loss of genetic diversity because they'd all be genetically identical. The real problem with cloning endangered animals is that it won't stop the poachers or habitat loss that's driving these species extinct in the first place.
Dying 😭 by the rhino egg extracting image
Also an animal needs to learn the behavior and be socialized.
So just wait for science and technology to improve
This is the kind of stuff billionaires should be funding. Great video, keep up the good work.
Just ask Craig for his cloning machine!!
Life, ah, finds a way.
Watching this ever those ceazy madlads done it be like: bruh
Arent there articificial wombs nowadays, at least in the experimental phase?
Can't we make a cloning vat yet?
Wheezy Waiter we need your help here...
Various countries are always complaining about the negative effect of poachers, but say they don't have the resources to combat them. I call BS on them. I love animals, and would more than enjoy stacking poachers like cordwood for a few Klondike bars and permission from their government.
Answer to your question. Yes we can clone animals out of extinction, but no, we probably shouldn't.
Would the T. Rex be considered the jaguar of the Cretaceous?
But maybe someday we'll have Zoos for animals that were definitely going extinct so that people can still see them & possibly care enough to do something about any species they still can. I'm imagining all sorts of science fiction type scenarios here lol
You realize that's the major mission of zoos today, right?
Now do one on artificial wombs. Cause then we'd be set.
Can you artifically make a germ line to then make eggs using stem cells?
Yes, as animals produce their own eggs when they originated as zygotes but the chemical process by which embryonic stem cells become egg cells is very complex. Plus it's hard to determine if a differentiated cell/embryonic cell require the same treatment to become egg producing cells, they should be working on how to turn skin cells of these animals into egg cells by first making iPSCs!!!
Im from Kazakhstan🇰🇿🤗
I thought all cows were called Daisy.
I love you
Cloning seems to be working fine for bananas.......
And avocados
There should be a machine that can scan any picture of any animal real, extinct or imaginary, and make an actual living replica of that said animal in the picture. This will not only quickly raise the population of endangered animals but also revive extinct animals like dinosaurs, and as well as making mythical and made-up animals like dragons and unicorns real.
You mean a giant 3d printer?
Can we clone buncha rino horns and throw it at the butcher ?
Hey, I have the same shirt.
I've never clicked on a video so fast
I'd love to clone both my guinie pigs that way I could have a spot 1 spot 2 hairy 1 and hairy 2 then I can NEVER put them together and test the theory nature vs nurture.
Dear sir/madam, we ask permission to use the video for Bioethics teaching materials. May I?
clone hank when?
Do people still think you can clone something with hair in spit?
so if we need the eggs and dna. why dont we just breed them alot and just skip the cloning process?
Poach the poachers.
Why does sheep C has to be the surrogate instead of just sheep A or B?
So when are we going to have a clone hank haunting the comments?
or just put them in a machine and click the "clone" button
You must be pissed off about the global warming scam since they claim cows are "bad for the environment." : czcams.com/video/Pxi4s0YTFJ4/video.html
Ok but why do i have butt on my hair?
Why don't we work on conservation of their habitat and clone the plant life?
Cloned plants can get easily wiped out by a fungus or disease. Look how much trouble we are having with bananas
The biggest problem is the LOCAL people in the area killing the endangered animals....mostly rinos and elephants.
I Love Pandas ❤❤❤❤
Dear pandas: EAT MEAT. Jesus, what is wrong with you guys?
*Cloning an endangered species only creates another endangered species*
?
Oh yeah lack of genetic variation
How does it *CREATE* a new endangered species?
@@magnuspeacock5857 Lol it doesn't create a New Endangered species. The wording ia slightly off.
It only further endangeres the animal because of yeah inbred.
I mean it'll probably be possible to gene edit biodiversity eventually.
I don't actually know anything on the subject so take what I'm saying with a grain of salt
what about bird cloning?
Didn't I see an article about an artificial womb scientists used to gestate a lamb earlier this year? Or did I just imagine that? czcams.com/video/dt7twXzNEsQ/video.html found it.
We still need to be taking lots of DNA samples in case we ever figure out how to do it easier.
“Cats starts ovulating after mating” mmm what? 🤔 can someone explain por favor?
