@Jerry C Ben Shapiro is also the name of a conservative talk show host who has famously said very dumb and terrible things. They are calling that Ben Shapiro evil, not the one in this video
Man, she's so ANIMATED! I didn't expect to watch it all but bam! And, the amount of things that have been cleared up in my head in the past hour is just unprecedented! :D
And the audience is a pile of dead fish. The only reason I know they were awake is that they laughed about the bratty, crying kid in the slide projection.
clear, concise, interesting, very engaging talk, easy to understand, no meandering, laser focus on the topic at hand yet still casual , building a momentum and keeping it up all the way through, great stuff kind of a benchmark on how it should be done
Loved the information covered in this speech, very informative. I however want to add, it would be great if Canada would ban accelerated melting of permafrost. The sloppy mass release of methane gas from the permafrost has to be staggeringly destructive to the ozone, not to mention improperly extracting rich and well preserved world history.
Great lecture. This is the best one I've seen in a while (last one is probably the black hole firewall with Sean Carroll on this channel). I usually watch physics related talks, but this was so engaging and she did a great job of conveying the concepts in laymen's terms. Hope to see more videos of this quality :)
You know this is a hot topic when the 5 year old sees the mammoth photo for the corresponding article in Popular Science and asks "is that an article about un-extincting mammoths?!"
I like Beth, she reminds me of the professor I had for Physical Anthropology a couple of years back. Really full of life and engaging. Also, I sure was surprised to hear that horses were originally American and bison originally Asian! Seems Beringia was important in both hemispheres!
Fascinating video. The idea of de extinction is very interesting. I think Beth made a good job at explaining the science and mentioning the ethic part was mature of her. It can easily be left out as this is such an exciting project.
edit: at 45:00 she does concede it may be possible in the future, right after talking about ethical concerns, as a qualifier. not much has been publicly reported about progress as the ethical concerns as the tricks needed to do it became forefront. nothing new publicly avaialble since 2019, and as I suspect, _private_ research has not stopped and only will be noted to media when a major breakthrough is "ready" to be announced
Consider altering - if possible- the genetic for tusk production in modern day elephants. Either remove the tusk completely, or potentially alter the construction so that it has no use in so called medicinal remedies. Hell, lace it with a chemical that won't hurt the elephant but cause severe irritation to humans if ingested or applied to skin.
Elephant ivory isn't used primarily in folk medicine. It's used for artistic objects no of great value. Also, every elephant will someday die and the tusks are valuable. Ivory could be a sustainable resource.
Changing the Asian elephant or any other animal to survive in a different climate for whatever reason means changing them for good... crazy thought in my opinion....! Humans should not mess with this sort of thing in any species full stop. That includes humans..... Why not just protect the these and other amazing creatures period....!
I really enjoyed this lecture. at times she is so passionate, and thought for a moment she'd shed a tear because she is emotionally connected to some efforts in this research only to come up against more road blocks
Personally, I'd settle for cloning Beth Shapiro. :) We'd need to make lots and lots of copies because every village, town, and city should have at least one Beth!
I just keep hearing Ian Malcolm's words in my head. This woman seems to get it though. The question should be whether or not we should more than whether or not we can.
One of the possibilities is to find a way to make American chestnut trees resistant to the fungus that destroyed great forests of these trees a century or so ago. I have read that researchers are trying to find some genetic fix so that these trees would be resistant and we could have the big chestnut tree forests again. But this seems to have been going on for decades without success. Will it ever succeed? There are living chestnut trees growing here and there in isolation from the fungus. It should be possible to insert the gene for resistance to fungus into the genome. Why has it not been done? Will it ever happen?
According to "How to Clone a Mammoth," Beth Shapiro argues that the overarching goal of de-extinction should be the stabilization and revitalization of contemporary ecosystems. True For those who got a quiz
that actually is a more viable research path and easier to do than bringing back an already extinct species. and there is probably a large number of entomologists that could clone bees easily. like the Dr. here mentioned the 'frozen zoo', if he DOESN'T have thousands of insects in his zoo he'd be NUTS! plus it wouldn't be so 'I am right and you are wrong!' confrontational on the root causes of colony uhh... what's the word? collapse, colony collapse. plus with the 'rewriting genomes' technology we could create 'Bionic Bees' or 'GM Bees' or 'SUPERbees' that would be immune to some if not all of the 'proposed causes' of CC. plus we could probably 'de-Africanize' killer bees as well. make populations of bees that would be immune to the 'sperm of Africanized bee drones'. therefore the 'GM Bees' would move throughout the US in nature and 'push out' the Africanized bees.
Absolutely great talk, really engaging, lots of info put in a understandable way for the non connoisseur and the ethics at the end make the link between science and human considerations an enjoyable experience.
? nope, it's worthless. you can't trade ivory unless it's an antique item with a DOCUMENTED provenance of a specific length of years, which I don't know that length. that's international law. the 'raw' ivory trade has been banned world wide for decades. so no, mammoth ivory is worthless, except to researchers and museums and folks visiting those museums. unless you want to get into gray or black markets and yeah... no thanks. getting killed, maimed, or going to prison for a very very long time... bad. very bad.
@@lesliekilgore648 Mammoth ivory is exempt. I'm not sure what to think about that, given that it means that a lot of mammoth DNA is being lost to make trinkets for China, but at the same time it incetivizes people to recover genetic samples for further study.
separating the 1% of what is important and what is mot so much will ultimately be the most difficult might get a closer looking elephant to a mammoth but it will never truly be a mammoth or Tasmanian tiger or whichever species they attempt to "bring back" Beth gave an amazing presentation though!
If you are going to call the period from the Eemian interglacial period some 125.000 years ago up to the present Holocene interglacial period an "ice age' then you will have to come up with a different term for the approx. 2.75m year period in which there have been numerous cycles between icy periods and warm periods.
Though Ms. Shapiro is obviously extremely well versed in the subject manner, I found some of her negative comments related to "de-extinction" surprisingly specious, yet I think she also missed what may be a significant obstacle. An example of the former is the elephant hyman. I can't help but think that a small incision, followed by a stitch or two would be sufficient to implant a mammoth embryo. However, should we overcome this and many other challenges, there is still another issue worth considering--mammals, at least when young, require a great deal of care and in many (most?) cases, it is during this time that they are taught basic survival skills. Intelligent and social de-extinctees (sorry, what should we call them?), such as mammoths reared by elephants, will lack this critical socialization and may be lack the skills to survive in the wild. Success of such efforts may require providing simulated parents that can bridge this critical gap, but that will require that we know not only what needs to be taught, but how to teach it. We're a long way from bring back mammoths, though I do expect there are other species that have fewer obstacles to overcome.
Changing the Asian elephant to survive in a different climate means changing the Asian elephant... crazy thought in my opinion....! Humans should not mess with this sort of thing in any species full stop. That includes humans..... Why not just protect the Asian elephant and other creatures period....!
Sorry didn't finish last posting. Darwin didn't exactly predict 'countless' intermediate forms in the fossil record. He predicted that transitional forms would be found, and in many cases they have. As for species appearing suddenly, this is correct, but it doesn't contradict evolution. In geological terms, 'suddenly' can be 100 thousand years. If we have two species at times X and X + 2, and we find another species at time X + 1 intermediate between the two, the most obvious interpretation is that the first form gave rise to the second which gave rise to the third. But if you demand that every tiny gradation by which form 1 led to form 3 should be discovered as fossils, you are setting the bar very high. And the existence of gaps is not, as this speaker suggests, a proof that Darwin was wrong, but it is precisely what you would expect given Darwin's theory. But this is not the end of the problems with ID. If ID wants to be taken seriously as an explanatory paradigm, it needs to provide a more convincing hypothesis for why things appear as they do in the fossil record. If evolution does not happen, then God must be constantly creating new species by fiat. Why? What is it about the nature of God that makes him do this? If you cannot give a 'God model' for this then your hypothesis is vacuous and it provides no alternative to Darwinism, however imperfect the latter is. I have as yet come across no description of how ID accounts for things as they are, merely a set of more or less well informed criticisms of the existing Darwinian paradigm. I am not impressed by ID so far, but maybe there is some real content to the theory out there somewhere. I wait in hope.
There was no need for a land bridge between Canada and Russia to foster migration. Animals could cross quite easily over the ice bridge that existed during glacial times.
The MM hockey stick, really??? Michael man is currently hiding on various continents hoping that he isn't forced by the courts to cough up scads of data and calculations which birthed the hockey stick graph. I predict that when that day arrives Professor man will claim, as others of his tribe have done, that the material was all accidentally deleted.
She's made it pretty clear that it's people digging for gold doing this and the scientists are just there to pick up the interesting bits that happen to wash out. Same as when fossils are found in quarries or construction sites. I'm also fairly certain the scale is so small as to be basically irrelevant.
Was the camera at the back of the hall much cheaper to operate or something? Every time she started talking about a chart of some sort, we'd see the chart for a couple of seconds, then the view cut away to the back of the hall as she talked on about the chart.
Wood Croft What Beth Shapiro calls "tighly condensed repeat regions" are generally known as "tandem repeats". In eukaryots, these are usually located at the center of a chromosome (centromere repeats), at the ends of a chromosome (telomere repeats) but can be found elsewhere. Tandem repeats are also found in bacteria and archaea: CRISPRs (from the CRISPR/Cas9 system mentioned in the talk) are some sort of interspaced tandem repeats (CRISPR stands for clustered regularly interspaced short palindromic repeats). Tandem repeats are not the only repetitive elements found in genomes. One must mention interspersed repeats such as transposons, retrotransposons or some introns. Actually, it is said that approximately 50% of the human genome is repetitive. You might find interesting (it is free access): J. Duitatama et al (2014). Large-scale analysis of tandem repeat variability in the human genome. Nucl. Acids Res. 42(9):5728-5741. I am sorry for such a long post. Best wishes!
Beniguitar94 Why is it hard to detect it? And when they publish a "complete" genome, if it's missing the tandem repeats, why do they call it "complete"?
Wood Croft Firstly, one must understand how genomes are sequenced nowadays (check out, for example, Roché 454 sequencing). Explained briefly, extracted genomic DNA is broken into fragments (300-800 base pairs in the case of 454 sequencing). Each fragment is sequenced (there are many elegant ways of doing it) and then comes the hard work: aligning these short reads (luckily they overlap) and deducing the whole sequence. It is even harder work to deduce the sequence of a tandem repeat from fragments which can get aligned in many several ways due to the repeats. You can read more about this (writen by experts) in the following link: www.ncbi.nlm.nih.gov/books/NBK21116/ With respect to your second question, the human genome has been mapped (not sequenced), which means that we now know the sequences of all genes and their location within the genome, plus intergenic regions (in total 90% of the human genome). Nevertheless, we do not know (exactly) the sequence of centromeres or telomeres. For example, click the following link to see the sequence of the Y human chromosome:(www.ncbi.nlm.nih.gov/nuccore/568815574?report=fasta) At the beginning of the sequence, you can read letter N (nucleotide), meaning that we don't know which nucleotide it corresponds (thought, we know the number of N's). If you drag your mouse down, suddenly, you will notice that sequence starts to appear (written in As, Cs, Gs, Ts). So the real question is, should we call "complete" a genome that has been mapped? In the days when the Human Genome Project was launched, non-genic genes (non-coding regions) where considered junk DNA. In that sense, it wasn't misleading to say "we know the complete genome". In the modern world, we are starting to grasp the essential function of so called junk DNA (we know call it noncoding DNA, which is more respectful). So my amateur opinion is that it is not at all complete and that it shouldn't be called that way.
Re Jurassic Park, it needed to be frog DNA so that the plot point would work where some of the dinosaurs changed sex, allowing them to breed. A bloody stupid reason, but still a reason.
Really, the problem with elephants is that they can't live in Siberia. If they could, we wouldn't have to protect them from habitat destruction, because there'd be more than enough habitat.
VHS Video Recorders are extinct. There is no habitat left for it and no use either. The same goes for bison, the hairy elephant and the pigeon with a suitcase on its back. Seems logical.
Well you can always see the brilliance and political mindsets of some people adding in their insults despite their ignorance. People that tend to lend accolades to themselves have a tendency to be less brilliant than they let on, ever notice that. First example is if you think Sarah Palin said she could see Russia from her house you'd be a bought head chump, she didnt say that SNL's Tina Fey did.. Does washing away permafrost help the environment or ice breakers, neh not worried about it do as we say not as we do.
what if you can get all the dna pussels from other mammoths dna ? so if one mammoth is missing some dna but maybe another mammoth have this missing dna data can you put them together maybe ?
i mean ! lets say !"this mammoth is missing the dna for the nervsystem , but you have more than 1 mammoth so maybe another mammoth will have this missing Dna for the nervsystem" !

With respect to your second question, the human genome has been mapped (not sequenced), which means that we now know the sequences of all genes and their location within the genome, plus intergenic regions (in total 90% of the human genome). Nevertheless, we do not know (exactly) the sequence of centromeres or telomeres. For example, click the following link to see the sequence of the Y human chromosome:(www.ncbi.nlm.nih.gov/nuccore/568815574?report=fasta)
At the beginning of the sequence, you can read letter N (nucleotide), meaning that we don't know which nucleotide it corresponds (thought, we know the number of N's). If you drag your mouse down, suddenly, you will notice that sequence starts to appear (written in As, Cs, Gs, Ts).
So the real question is, should we call "complete" a genome that has been mapped? In the days when the Human Genome Project was launched, non-genic genes (non-coding regions) where considered junk DNA. In that sense, it wasn't misleading to say "we know the complete genome". In the modern world, we are starting to grasp the essential function of so called junk DNA (we know call it noncoding DNA, which is more respectful).
So my amateur opinion is that it is not at all complete and that it shouldn't be called that way.
Telomeres...
American Chestnut trees!
Why does the clip at 1:17 min give me the feeling like its straight out of a cheap horror movie.
Re Jurassic Park, it needed to be frog DNA so that the plot point would work where some of the dinosaurs changed sex, allowing them to breed. A bloody stupid reason, but still a reason.
Would elephants be elephants if we altered their genome?
They would be a hybrid of Mammoth and Elephant.
Would it be at all important to make things easy and keep species from going extinct in the first place?
9 years later and no mammoth steaks in the supermarkets !
she's a good story teller!
5 years later i wonder how things have progressed
Really, the problem with elephants is that they can't live in Siberia.
If they could, we wouldn't have to protect them from habitat destruction, because there'd be more than enough habitat.
maybe they could live there in summer and would gradually reevolve o mammoth-like
Fun fact: African elephant are older and bigger than mommoth
If we do this once, someone will make a pair of T-Rex's and we're screwed.
Is she related to Ben Shapiro?
This was brilliant
35:21 Time to dope with the woolly mammoth Hb during the next winter olympics.
I think no doubt they should clone a mammoth asap.
If you could adapt an animal for life on another planet it would be a black footed ferret, so cute. Which animal would you choose?
Here's a thought...mammoths didn't live in arctic conditions.
VHS Video Recorders are extinct. There is no habitat left for it and no use either. The same goes for bison, the hairy elephant and the pigeon with a suitcase on its back. Seems logical.
Hey I have my father old recorder with lots of vhs. Speak for your self.
Well you can always see the brilliance and political mindsets of some people adding in their insults despite their ignorance. People that tend to lend accolades to themselves have a tendency to be less brilliant than they let on, ever notice that. First example is if you think Sarah Palin said she could see Russia from her house you'd be a bought head chump, she didnt say that SNL's Tina Fey did.. Does washing away permafrost help the environment or ice breakers, neh not worried about it do as we say not as we do.
She's a professor in California...are you surprised?
'just like us' - twilight zone - People Are Alike All Over
Apparently the “talk fast gene” is strong in the Shapiro line… unless it’s her married name and then it’s an environmental adaptation.
Would be so cool to have Mammoths 2.0, elephants reloaded :D
what if you can get all the dna pussels from other mammoths dna ? so if one mammoth is missing some dna but maybe another mammoth have this missing dna data can you put them together maybe ?
i mean ! lets say !"this mammoth is missing the dna for the nervsystem , but you have more than 1 mammoth so maybe another mammoth will have this missing Dna for the nervsystem" !
Hans Henrik Büttner so and extreme jig saw puzzle???
A little bit mamooth-like
of course its a good idea , its the cost thats matters
I want a mammoth that is the size of a pig. Make it happen, science.
I want a flying monkey so I don't have to walk to school.
I like her, she's silly and right.
I'm gonna plunder my bank account and throw money at her idea's 👍-up.
i enjoyed this beth thank you:)
