Building a dinosaur from a chicken | Jack Horner

Building a dinosaur from a chicken | Jack Horner

When I was growing up in Montana, I had two dreams. I wanted to be a paleontologist, a dinosaur paleontologist, and I wanted to have a pet dinosaur. And so that’s what I’ve been striving for all of my life. I was very fortunate early in my career. I was fortunate in finding things. I wasn’t very good at reading things. In fact, I don’t read much of anything. I am extremely dyslexic, and so reading is the hardest thing I do. But instead, I go out and I find things. Then I just pick things up. I basically practice for finding money on the street. (Laughter) And I wander about the hills, and I have found a few things. And I have been fortunate enough to find things like the first eggs in the Western hemisphere and the first baby dinosaurs in nests, the first dinosaur embryos and massive accumulations of bones. And it happened to be at a time when people were just starting to begin to realize that dinosaurs weren’t the big, stupid, green reptiles that people had thought for so many years. People were starting to get an idea that dinosaurs were special. And so, at that time, I was able to make some interesting hypotheses along with my colleagues. We were able to actually say that dinosaurs — based on the evidence we had — that dinosaurs built nests and lived in colonies and cared for their young, brought food to their babies and traveled in gigantic herds. So it was pretty interesting stuff. I have gone on to find more things and discover that dinosaurs really were very social. We have found a lot of evidence that dinosaurs changed from when they were juveniles to when they were adults. The appearance of them would have been different — which it is in all social animals. In social groups of animals, the juveniles always look different than the adults. The adults can recognize the juveniles; the juveniles can recognize the adults. And so we’re making a better picture of what a dinosaur looks like. And they didn’t just all chase Jeeps around. (Laughter) But it is that social thing that I guess attracted Michael Crichton. And in his book, he talked about the social animals. And then Steven Spielberg, of course, depicts these dinosaurs as being very social creatures. The theme of this story is building a dinosaur, and so we come to that part of “Jurassic Park.” Michael Crichton really was one of the first people to talk about bringing dinosaurs back to life. You all know the story, right. I mean, I assume everyone here has seen “Jurassic Park.” If you want to make a dinosaur, you go out, you find yourself a piece of petrified tree sap — otherwise known as amber — that has some blood-sucking insects in it, good ones, and you get your insect and you drill into it and you suck out some DNA, because obviously all insects that sucked blood in those days sucked dinosaur DNA out. And you take your DNA back to the laboratory and you clone it. And I guess you inject it into maybe an ostrich egg, or something like that, and then you wait, and, lo and behold, out pops a little baby dinosaur. And everybody’s happy about that. (Laughter) And they’re happy over and over again. They keep doing it; they just keep making these things. And then, then, then, and then … Then the dinosaurs, being social, act out their socialness, and they get together, and they conspire. And, of course, that’s what makes Steven Spielberg’s movie — conspiring dinosaurs chasing people around. So I assume everybody knows that if you actually had a piece of amber and it had an insect in it, and you drilled into it, and you got something out of that insect, and you cloned it, and you did it over and over and over again, you’d have a room full of mosquitos. (Laughter) (Applause) And probably a whole bunch of trees as well. Now if you want dinosaur DNA, I say go to the dinosaur. So that’s what we’ve done. Back in 1993 when the movie came out, we actually had a grant from the National Science Foundation to attempt to extract DNA from a dinosaur, and we chose the dinosaur on the left, a Tyrannosaurus rex, which was a very nice specimen. And one of my former doctoral students, Dr. Mary Schweitzer, actually had the background to do this sort of thing. And so she looked into the bone of this T. rex, one of the thigh bones, and she actually found some very interesting structures in there. They found these red circular-looking objects, and they looked, for all the world, like red blood cells. And they’re in what appear to be the blood channels that go through the bone. And so she thought, well, what the heck. So she sampled some material out of it. Now it wasn’t DNA; she didn’t find DNA. But she did find heme, which is the biological foundation of hemoglobin. And that was really cool. That was interesting. That was — here we have 65-million-year-old heme. Well we tried and tried and we couldn’t really get anything else out of it. So a few years went by, and then we started the Hell Creek Project. And the Hell Creek Project was this massive undertaking to get as many dinosaurs as we could possibly find, and hopefully find some dinosaurs that had more material in them. And out in eastern Montana there’s a lot of space, a lot of badlands, and not very many people, and so you can go out there and find a lot of stuff. And we did find a lot of stuff. We found a lot of Tyrannosaurs, but we found one special Tyrannosaur, and we called it B-rex. And B-rex was found under a thousand cubic yards of rock. It wasn’t a very complete T. rex, and it wasn’t a very big T. rex, but it was a very special B-rex. And I and my colleagues cut into it, and we were able to determine, by looking at lines of arrested growth, some lines in it, that B-rex had died at the age of 16. We don’t really know how long dinosaurs lived, because we haven’t found the oldest one yet. But this one died at the age of 16. We gave samples to Mary Schweitzer, and she was actually able to determine that B-rex was a female based on medullary tissue found on the inside of the bone. Medullary tissue is the calcium build-up, the calcium storage basically, when an animal is pregnant, when a bird is pregnant. So here was the character that linked birds and dinosaurs. But Mary went further. She took the bone, and she dumped it into acid. Now we all know that bones are fossilized, and so if you dump it into acid, there shouldn’t be anything left. But there was something left. There were blood vessels left. There were flexible, clear blood vessels. And so here was the first soft tissue from a dinosaur. It was extraordinary. But she also found osteocytes, which are the cells that laid down the bones. And try and try, we could not find DNA, but she did find evidence of proteins. But we thought maybe — well, we thought maybe that the material was breaking down after it was coming out of the ground. We thought maybe it was deteriorating very fast. And so we built a laboratory in the back of an 18-wheeler trailer, and actually took the laboratory to the field where we could get better samples. And we did. We got better material. The cells looked better. The vessels looked better. Found the protein collagen. I mean, it was wonderful stuff. But it’s not dinosaur DNA. So we have discovered that dinosaur DNA, and all DNA, just breaks down too fast. We’re just not going to be able to do what they did in “Jurassic Park.” We’re not going to be able to make a dinosaur based on a dinosaur. But birds are dinosaurs. Birds are living dinosaurs. We actually classify them as dinosaurs. We now call them non-avian dinosaurs and avian dinosaurs. So the non-avian dinosaurs are the big clunky ones that went extinct. Avian dinosaurs are our modern birds. So we don’t have to make a dinosaur because we already have them. (Laughter) I know, you’re as bad as the sixth-graders. (Laughter) The sixth-graders look at it and they say, “No.” (Laughter) “You can call it a dinosaur, but look at the velociraptor: the velociraptor is cool.” (Laughter) “The chicken is not.” (Laughter) So this is our problem, as you can imagine. The chicken is a dinosaur. I mean it really is. You can’t argue with it because we’re the classifiers and we’ve classified it that way. (Laughter) (Applause) But the sixth-graders demand it. “Fix the chicken.” (Laughter) So that’s what I’m here to tell you about: how we are going to fix a chicken. So we have a number of ways that we actually can fix the chicken. Because evolution works, we actually have some evolutionary tools. We’ll call them biological modification tools. We have selection. And we know selection works. We started out with a wolf-like creature and we ended up with a Maltese. I mean, that’s — that’s definitely genetic modification. Or any of the other funny-looking little dogs. We also have transgenesis. Transgenesis is really cool too. That’s where you take a gene out of one animal and stick it in another one. That’s how people make GloFish. You take a glow gene out of a coral or a jellyfish and you stick it in a zebrafish, and, puff, they glow. And that’s pretty cool. And they obviously make a lot of money off of them. And now they’re making Glow-rabbits and Glow-all-sorts-of-things. I guess we could make a glow chicken. (Laughter) But I don’t think that’ll satisfy the sixth-graders either. But there’s another thing. There’s what we call atavism activation. And atavism activation is basically — an atavism is an ancestral characteristic. You heard that occasionally children are born with tails, and it’s because it’s an ancestral characteristic. And so there are a number of atavisms that can happen. Snakes are occasionally born with legs. And here’s an example. This is a chicken with teeth. A fellow by the name of Matthew Harris at the University of Wisconsin in Madison actually figured out a way to stimulate the gene for teeth, and so was able to actually turn the tooth gene on and produce teeth in chickens. Now that’s a good characteristic. We can save that one. We know we can use that. We can make a chicken with teeth. That’s getting closer. That’s better than a glowing chicken. (Laughter) A friend of mine, a colleague of mine, Dr. Hans Larsson at McGill University, is actually looking at atavisms. And he’s looking at them by looking at the embryo genesis of birds and actually looking at how they develop, and he’s interested in how birds actually lost their tail. He’s also interested in the transformation of the arm, the hand, to the wing. He’s looking for those genes as well. And I said, “Well, if you can find those, I can just reverse them and make what I need to make for the sixth-graders.” And so he agreed. And so that’s what we’re looking into. If you look at dinosaur hands, a velociraptor has that cool-looking hand with the claws on it. Archaeopteryx, which is a bird, a primitive bird, still has that very primitive hand. But as you can see, the pigeon, or a chicken or anything else, another bird, has kind of a weird-looking hand, because the hand is a wing. But the cool thing is that, if you look in the embryo, as the embryo is developing the hand actually looks pretty much like the archaeopteryx hand. It has the three fingers, the three digits. But a gene turns on that actually fuses those together. And so what we’re looking for is that gene. We want to stop that gene from turning on, fusing those hands together, so we can get a chicken that hatches out with a three-fingered hand, like the archaeopteryx. And the same goes for the tails. Birds have basically rudimentary tails. And so we know that in embryo, as the animal is developing, it actually has a relatively long tail. But a gene turns on and resorbs the tail, gets rid of it. So that’s the other gene we’re looking for. We want to stop that tail from resorbing. So what we’re trying to do really is take our chicken, modify it and make the chickenosaurus. (Laughter) It’s a cooler-looking chicken. But it’s just the very basics. So that really is what we’re doing. And people always say, “Why do that? Why make this thing? What good is it?” Well, that’s a good question. Actually, I think it’s a great way to teach kids about evolutionary biology and developmental biology and all sorts of things. And quite frankly, I think if Colonel Sanders was to be careful how he worded it, he could actually advertise an extra piece. (Laughter) Anyway — When our dino-chicken hatches, it will be, obviously, the poster child, or what you might call a poster chick, for technology, entertainment and design. Thank you. (Applause)

  3. God made birds on day 5, and dinosaurs on day 6.
    They have similarities, because God reused his good ideas.
    We build houses the same, boats the same.
    Intelligence will always re-use effective designs.
    Why would mutation (evolution) have similarities?
    Mutation is Mutilation. Change the 01101001 of a computer and see how long it works.
    Birds came BEFORE dinosaurs.
    Of course you can turn a chicken into a dinosaur. That's what God did.
    Evolutionists got it backwards again.

  4. What came first, the chicken or the egg? Of course it’s the egg, dinosaurs came out of eggs way before they turned into chickens

  5. 14:20 Energy-saving nature like resource-starved game devs: Patches are being applied in immediate pre-release phase. The base code was never fixed. Long-term this actually seems to be a waste of energy. … Oh well… humankind reflects and imitates nature. Nature makes mistakes and does clumsy things at times. Evolution is fear-driven. What else do you expect?
    So Jack Horner wants to do what they did in Jurassic Park – bring Dinosaurs into the world, but we totally won't make the mistakes they made in the movie. Because reality is much more professional and careful than the movie world. ? (The chances are greater that humankind annihilates itself believing they're saving the world than through nuclear world war, so don't count on its wisdom.)

  6. Warning human: "We should never have ventured into this territory. Creating dinosaur chickens is too dangerous!"
    Awesome and very self-defense-capable dinosaur chicken: "I really don't like where you're going with this."

  7. The major question is , millions of years old there should be nothing, but Jack has refused to do carbon 14 dating on the tissue. He is afraid because of his ego. He would find the material to be 10s of thousands of yrs old. Tests have been done.

  8. I guess teaching people with humor is a good thing, but I'd rather get the info without the comedy timing…

  9. NEWS FLASH: It is IMPOSSIBLE to bring back any creature that has died, because LIVING DNA is required. You need a living cell, there are no exceptions! If you want to ride on a bicycle you first NEED to have a bicycle, imagining you have one or holding a tire in your hand won't help!

  10. Peace.
    It seems this gentleman is talking about important stuff to do with large birds called the dinosaurs, though not quite sure what it is..

  11. dinornis robustus 12 ft tall carnivorous flightless bird. No thankyou. turkeys are a terror just as they are, and chickens less so, only because they are small(er).

  12. I'm a proud owner of 5 avian dinosaurs ?????. They may not be as cool as their ancestors, but they are cute, affectionate , entertaining, and lay eggs! Thumbs up if you own chickens ❤

  13. Heres the latest I could find… he's talking about needing just some more funding to do it now 🙂

  14. Yes, you can create hybrids, it's all there in the Bible. Certain dinosaurs were hybrids, which the fallen angels probably well as Giants, whose bones were found quite often.

  15. never gonna find the link or the change because there isn't one, the fossil record has NEVER been able to find ANY fossils with changes, meaning a dog from 10,000 years ago looks the same as a dog today cat fish all of it the same there are not any fossils that show evolution. but don't believe what i have to say go do your own research and find your own answers

  16. Tissues can be extracted from dinosaurs because they died out 12,000 years ago during the great cataclysm- not millions, as we have been told. The fossils and the strata layers in which they are found were formed all at once during the flood through the process of liquefaction. This is the only way fossils are formed. These facts are also proved by the existence of multi-strata fossils and human/dinosaur/trilobite fossils existing in the same river beds…

  17. Horner retired in 2016. Written in a 2018 artical, Dana Rashid, is now taking over for what's now called the dinochicken lab & has said that while it will be possible in 5 years, its not our primary goal. Horner has said that with 300,000 to a million, it is possible to produce this hybrid chicken in a year.

  18. He makes fun of a film about dinosaurs(factual or not) but that film got a lot kids and adults in to dinosaurs so just thought its a cheap shot making fun of something that happens in a hollywood film just for a cheap laugh

  19. Maybe if it has blood….it's not 65 million years old. Crazy how its so hard for them to admit that.

  20. It seems that a 6th grader is smarter than this guy. 6th grader may know about the bait and switch but evolutionists are kinda good at it if you are not paying strict attention. Evolutionists like this guy will talk about micro evolution and down the line slip macro evolution as though they are the same thing.

  21. Is it possible then that the dinasaours with mammilian bone structure are in fact mammals if dinasaours wirh bird bone structure are birds? If a duck billed platapous can be a mammal and lay eggs why not a triceratops or brachiosaurus?

  22. Hello first time watching, I subscribe I too was a fourth grader had special dinosaurs that I really really liked and now looks like we may see one in real life other than the chicken thank you.?

  23. See that's not evolution that is biologic manipulation evolution is a farce unprovable and it should not be taught in our schools not ever has it been something made from nothing and I know it's hard for some of you to understand this Darwin's theory of evolution was wrong 150 years later you're still trying to hang on to a white supremacist to the point of incest and interbreeding his first three children died because of his marriage to his first cousin I'm trying to keep a pure bloodline

  24. They're trying to make monsters really. how are they going to say evolutionary biology but they are intelligently designing a creature?


  26. I'm sure he knows what he is talking about since its his job XD but I saw this TV documentary on this same basis of trying to find DNA but with mammoths

    Anyway, they found mammoth bones somewhere in north-east Siberia and inside the bone they found live mammoth DNA

    If they found live DNA in frozen mammoth bones then why couldn't this guy's team do the same?

    I assume it has something to do with the mammoth being frozen in ice and the dinosaur bones not but I have no idea XD

    it would be nice to get some answers on this from people who know more about it. Thanks!

  27. You fucking scientists, you think that you can play God. You all think you know everything, while in reality you know nothing.
    It all comes down to the biblical text about Adam and Eve eating from the tree of knowledge. Satan said you will be as Gods. So here we are today with scientists thinking that they can accomplish anything God did. You're all a bunch of fools. Playing God and being God are two entirely different things.

  28. I love that, and this is very rare in academic circles, his wit and ability to engage an audience truly is directly proportional to his obvious intelligence.

  29. ??????????? … We can turn on some regenerative genes and maybe … one day … will be able to stop handicaps occurring because of pollution or drugs… We could reverse the limbs dystrophy and kids would be able to be born with well shaped feet and hands …
    Love the chickenosaurs ❤?

  30. I LOVE this… 🙂 Show 'em a turkey with its eye on a fat mealworm, or a hen ditto. THEY ARE DINOSAURS!! 🙂 I want to hear this man speak more….lots more….wonder what he's up to now in 2019?

  31. I am 11 years old and I am happy that dinosaurs had feathers and birds are cool.And I am also happy that birds are dinosaurs.

  32. I can still remember bits of my first documentary video at 5 or 6 years old in the early 90's. A video of Jack's Maiasaur babies hatching in a nest with their mom looking on. Fell in love with dinosaurs and got a few plastic ones to play with 🙂

  33. Here in Australia up in the tropics we have a bird called a cassowary. About the size and shape of an emu and it has a cool bone thing on its head and it will hit vital organs with its claw. Hence why I call the Cassowary a Velocrapter

  34. Chickens have most of the dinosaur traits. They are omnivores, they eat meat as well as vegetable matter, (think bugs, etc.), but occasionally, usually when packed too tightly together in a breeding area, they will kill and eat small chicks. Occasionally a flock will gang up on one chicken and peck it to death. Roosters fight and sometimes kill each other over "harem rights". Look closely into a chicken's eyes and you will see the cold, emotionless calculating soul of a reptile. I know reptiles aren't dinosaurs, but you'll know what I mean when you do it. Chickens are scary and I hope they never make a really big one!

  35. I dont know why some scientist make thangs so difficult it take one cell to start to make more cells to bring something to life and some people forget the one and important thangs dna and cells are the samethang red blood cells white blood cells are the same thang and thinks i thinks scientist are looking in the wrong place if you really bring dinosaur back to life stop wasting everytime andgo with something like a fraking alligator since they are since they are closely to the dinosaur family

  36. Some years ago , my then young son suggested that dinosaurs are in fact hybrids of birds and lizards . Interestingly , if you look at a T-rex skeleton and a chicken skeleton side by side , you will notice that the T-rex does in fact look like it was a hybrid .
