Is it possible to clone a dinosaur ? Or could we play back dinosaur some other way of life ? We ask because it ’s the 30th day of remembrance ofJurassic Park , and we ’ve draw dinosaur on the brain .
In the lead - up , we decided to dive into the world of animal cloning and dinosaur husbandry by speaking to researcherDr Susie Maidment of London ’s Natural story Museumand Ben Lamm , founder and chief operating officer at Colossal Biosciences , who are seek to"de - out " the dodoand woolly mammoth among other creatures . Recorded as part ofThe Big Questions , IFLScience ’s podcast , we cover how far cloning applied science has hail , some flaws in the logic ofJurassic Park , and why dino odontology is going to have to become a affair if we bring back the dinosaurs .
What do we bonk so far about the possibility of bringing dinosaur back ?

Dr Susie Maidement : Well , people have had some idea about how we might be able tobring dinosaurs back . The first one inJurassic Parkwas the estimation that we could peradventure extract some rip from a mosquito and then take the DNA from that to fill in the gaps in “ dino DNA ” , and then clone a dinosaur . Well , we still ca n’t do that 30 years on from the pic , and that ’s because we have n’t found any DNA from dinosaur .
In fact , the oldest DNA in the fossil disk is credibly only around a million years old , peradventure a second more . The dinosaurs go bad out 66 million years ago , so decidedly we do n’t have any DNA for dinosaurs at this point . We do , however , now have some blood , so we have somered blood cellsthat are preserved from dinosaur andsome other easygoing tissuefeatures . So peradventure in the hereafter we might be able to get some DNA .
There are a couple of other dissimilar techniques that are going on though . One of those is reverse engineering science , which is this estimation that you could take birds , which are the direct descendent of the dinosaurs , diddle around with their genetics , and bring about something like a dinosaur .

When you ’re speak about the precious dino deoxyribonucleic acid there , inJurassic Parkthey use a mosquito pin in amber . Could that be a source ?
samarium : When we bet at insects in amber , what we be given to find is the outside of the louse , the chitinous husk – or the crunchy bit , if you like – of the insect , but the inside stuff is n’t preserved . So , there is n’t any blood found within those . But there has been a beautiful specimen of amosquito found preserved in lake deposit . So , these are very finely laminated , finely layer sediments , and this specimen had a disconsolate stain around its venter .
When they tested that , they actually found the breakdown products of Hb . So , it was blood in a mosquito ’s abdomen , however , that specimen was only 60 million years former , so not old enough to be around at the same clock time as the dinosaurs .

A massive spread , then , between where we ’re at now and where we call for to get to . In the motion-picture show , when they extract the desoxyribonucleic acid from the amber specimen , they get this genome but it ’s not quite complete , so their musical theme is “ Well , we ’ll just get a bit of a anuran , and we ’ll plug away in the gap . ” Could that figure out ?
SM : There are some fairly major flaws with this whole construct . Firstly , to know where the gaps in the DNA are , you need to have the whole genome to set off off with , otherwise you do n’t know which bits are missing .
The 2d problem is that frogs are the least potential organism you would opt . The being that you would opt would be birds , because raspberry are the direct descendants of dinosaurs . WhenJurassic Parkcame out , I do n’t retrieve that was 100 percent accepted . There were some ideas that it might be the case , but it was n’t as widely have as it is now .
Now that ’s just fact , but they still would n’t have used salientian . Humans are more tight come to to dinosaurs than toad frog are . So it was totally a bizarre selection , but it was needed for the narrative of the film . They needed the dinosaurs to be able to change sex activity randomly and then produce progeny and this is something that some frogs can do .
[ Interestingly , since our interview with Maidment research has come out saying that the discovery ofparthenogenesis in a crocodilemakes it “ very potential ” that pterosaurs and dinosaurs were also open of reproduce without intimate reproduction . So , it could be thatJurassic Parkwould’ve been a total disaster even without that pesky amphibian DNA genome jade . ]
Elsewhere in the flying field of animal cloning , co - laminitis and CEO of Colossal Biosciences Ben Lamm has been forge towards the “ de - quenching ” of several out species . We asked him what exactly that imply .
Ben Lamm : Colossal Bioscience is , to our knowledge at least , the public ’s first de - extinguishing and species conservation company . What that means to us is looking at and apprehension which genes are associated with the core phenotypes , or strong-arm attributes , that existed in an extinct animal .
For example , for the woolly mammoth , it ’s the dome cranium , the curved ivory , and whatever is making it cold - tolerant , as well as a lot of thing under the hood . Things like how nerve close react to freezing temperature , how the body grow Hb , and the bushy woollen coat .
What we ’re ask is how can we at Colossal realize the core factor that made elephant stale tolerant . Those genes are now nonextant , so how do we de - extinct those cistron and put them into the computer architecture , if you will , of an existing living animate being ? At the moment , that ’s the Asian Elephant which is 99.6 percent the same genetically as a woolly mammoth . If we can de - extinct those genes , then you have the mammoth 2.0 .
What other species have Colossal get their vision set on for Delaware - extinction ?
BL : We’re puzzle out on thewoolly mammoth , the Tasmanian wolf , also live as the Tasmanian tiger , and then the iconic fossil from Mauritius .
When you ’re do work with these different species , what ’s the bare minimum you need in terminus of biological cloth to forge with ?
BL : First you need to look at , what is the close phylogenetic relative ? What is the animal that is still existing on the satellite that ’s the closest on the household tree ? For example , for the woolly mammoth , that ’s the Asian Elephant . As I mentioned , it ’s 99.6 pct the same , genetically . Most people do n’t realize this , but an Asian Elephant is nearer genetically on the family line Sir Herbert Beerbohm Tree to the woolly mammoth than it even is an African elephant . You need to get the finis phyletic relative because you ’ve got to find and progress a reference genome , and you need tissue sample to do that .
Then , you ’ve beget to get tissue sample distribution containing theancient deoxyribonucleic acid of those extinct specie . Ancient DNA is different from existing experience DNA , because it ’s massively disunited . It ’s not all exogenic , mean that there are other bug and living things that have foul it over time . So you get snippets of ancient DNA and then you basically piece them together . With the mammoth , we really used 54 differentmammoth genomesto build our reference genome .
Then lastly , you need a surrogate that will be able to house the genetically modify embryo once you get there .
Getting that ancient desoxyribonucleic acid from tissue sample , does that get harder and harder the further back in evolutionary sentence that you ’re working with ?
BL : Yeah . It ’s also condition . So , there are beast that are extinct more of late than mammoths that move extinct in very spicy and wet place . That ’s not a outstanding place for DNA . Cold , dry places are great . thing like cave or the Arctic , in the case of the permafrost .
The Thylacinus cynocephalus get nonextant in 1936 , and peoplepreserved some pupsin grain alcohol for scientific study , so from that we were able to sequence a intimately concluded genome . So , it really depend . Sometimes you get golden , but broadly speaking , the further back you go and the hot , wetter places you are , it find harder .
Just before we move on to dinosaurs , you note there about specie that have gone extinct in more advanced time . That ’s a really interesting point because your company , beyond the de - extinction of long - lose species , also intends to stand preservation undertaking , right-hand ?
BL : All of the technology that we develop on the way of life to de - defunctness , some of them have diligence to human healthcare which we are monetizing . We did that last class , we spun out our first computational biological science chopine , but all the technology that could add to assisted procreative technologies or preservation groups for zoos or animal groups worldwide , we are subsidizing and giving to the Earth for gratis .
Those are puppet like better semantics on atomic transfer technique and better computational biology for research . All the data we build on Asiatic and African elephant we publish to science so that hoi polloi can habituate those . A lot of these technologies can not only be used to convey back mammoth , but can also help critically threaten species .
We ’re also working towards technologies like contrived uterus – which are a way off , it ’s much more likely you will see out fauna from us before we see stilted wombs – but once we get there , call back about what that could mean for coinage like theNorthern white rhino , where there are only two females leave .
If we could clone them or create genetically modified variant of them , inserting DNA from other lineages that do n’t exist anymore , and you inclose that biodiversity , then you could grow them in a research laboratory and do work with great re - wilding partners to put them back in the wilderness . That ’s pretty awesome .
We believe it could be transformative for preservation . So , this Diamond State - extinction creature outfit that we ’re build over clock time with our specie , we require to make useable and free for every conservation radical out there .
So what if we really let our imaginations run violent , and we did wreak back dinosaurs ? What happens next ? As Dr Maidment explained , animal welfare does n’t get any easier when you ’re address with long - extinct species .
SM : There are all sorts of problems here . First of all , the dinosaur live for 170 million year on Earth . That ’s a really foresighted metre . T. rexis in reality nearer to us in meter than it was to Stegosaurus . Many dinosaurs were already fossils by the clock time other unity lived , so you ’re bringing all these dissimilar animal together and place them alongside each other , already that ’s weird .
But also , what about the things that they eat ? Grass had n’t evolved when the dinosaurs were around , so the herbivores were n’t eating smoke , and smoke is quite difficult to wipe out . It has lots of bits of almost glass - like material in it , which causes your teeth to fall apart down really , really fast . Horses have germinate these very gamy crown tooth which wear down over clip , but dinosaurs did n’t have that . They replaced their tooth continuously throughout their lives .
If they were eating Gunter Wilhelm Grass , could they have digested it ? Could their teeth successor rate keep up with being worn away ? Would some of these works today be poisonous for these dinosaur that survive in a world where flowering plants had n’t even evolve yet ?
I think there is a mo of fear over what they would eat and how they would get on with each other . But of form , what rights would they have today ? Would they be treat like livelihood animals ? Or because we ’ve invented them and reconstructed them , would they have a different status ? There are a bunch of ethical business organisation around it as well .
Opening up a new era of dino dentistry could be exciting , but it ’s probably a difficult sell for modern menagerie . However , as Ben tell me , we probably do n’t require to occupy about seeing a living , breathingT. rexany fourth dimension shortly .
BL : We are ask the dinosaur inquiry all the time . People sleep together mammoth , people have a go at it dodos , and plainly thylacines too , but peoplereallywant dinosaur . We get in all likelihood two or three emails a day about dinosaurs .
I do n’t want to break ticker , but it is not possible to de - nonextant a dinosaur .
Every so often , you will see some press or newspaper that ’s like , “ Oh we got some dino DNA ” . Like Ken Lacovara who is arguably the numeral one paleontologist in the world that discoveredDreadnoughtus . He ’s amazing , he ’s one of our scientific adviser , he ’s believably been the closest because he ’s really formulate a physical process to de - mineralize dinosaur bones and get canonical sherd of aminic acids but , you screw , we ’ve just had amino window pane for our gigantic project but we ’re not function on it because it ’s not possible .
So , it ’s not presently scientifically potential to bring in back a dinosaur . I do think that the tools over the next 20 years could get us to the point where you could engineer species with dinosaur - comparable trait . However , unlike our study with the mammoth , we ca n’t really reckon at the genome and key out those core genes and Delaware - extinct them , so I do n’t think it ’s possible to bring back a dinosaur or de - extinct one .
I do recall that over meter you could plausibly engineer dinosaur - like affair , but I think then you ’ve really sire to expect yourself why ? Why are you doing it ? What ’s the intent ? How does this help the cosmos ? How does this serve our ecosystems ? How does this assist humanity ? I think you ’ve got to be really paying attention about it .
Bringing back the dinosaurs take in for a swell movie , but it ’s not necessarily useful scientific discipline . However , if we were to discombobulate caution and scientific restriction to the wind and just have merriment with it , what dinosaur would you most like to see live ?
BL : I would list towards theT. king . Once again , I ’m not boost anyone to work on theT. rexbecause I believe that would be big and scary and terrifying for the world . We already have enough existential job decent now , we do n’t need toaddT. rexesto our current tilt of problems . We demand to focus on political science and mood modification , let ’s focus on the existing problems before we introduce new ones .
Over at the Natural History Museum , it seems like the scientific , logistic , and safe business organisation around bringing dinosaur back from the dead have put Dr Maidment off solely .
samarium : Well firstly , did you watch the film ? It did n’t end well . So , I ’m going to say that perhaps it ’s not the best idea . I think if I had to choose one , it ’s really cunning , because I would say Stegosaurus because it ’s what I work on . It ’s a dinosaur that I know really well , but then I ’d be out of a problem , so you know , I do n’t know that I ’d choose any to be honest with you .
An unexpected answer , but we like it .
last , and it ’s a interrogation that ’s burn in our brain for the preceding three ten : could a Velociraptor really open a door ?
Master of Science : The substance - eating dinosaurs had their hands face up each other , so their palms come together . If you imagine the hand place of clapping and typing , they were clappers . So , their palms could n’t face up the level .
For most meat - feed dinosaur , they could n’t have go around their articulatio radiocarpea round to open a door , their wrists do n’t work like ours . Things like Velociraptors had the power to almost fold their arms backwards like a wing , because this is where annexe evolved from in dinosaurs very similar to them . So , they had this bone in their wrist that would have allowed their articulatio radiocarpea to fold back , but I ’m still not totally confident that it could have operate a door handle . So , I think we ’re dependable .
All you need to beat a Velociraptor is to make a threshold – you find out it here first , folks .
We ’ve tease the movie a bit , but the realness is it ’s a film that has shaped the sprightliness of many masses at IFLScience – our quad correspondent Dr Alfredo Carpineti even hosted a 30th - day of remembrance dinner complete with token jelly wobble . What didJurassic Parkmean to you ?
Master of Science : I was 12 whenJurassic Parkcame out . I pop off to see it with my first boyfriend . We take for hands in the queue , it was a very special moment . I think for me , because I was a young teenager , it made like dinosaur and thinking dinosaur were interesting and cool down a little bit more socially acceptable , which as a girl in the early ' 90s was n’t always necessarily the case .
I consider it made the bailiwick a fleck more socially acceptable and I think also , it made dinosaur really stars in the great unwashed ’ minds . It brought them to the head , and I think that did a lot for paleontology as a whole because it increase funding to the study , and really glitter a light on dinosaur inquiry , which helps all of us in the end .
perfectly . So , as far as the scientific discipline goes it seems like cloning dinosaurs is believably not that likely but then , what is it they say ?
Life – uh – finds a way .
