Welcome to Jurassic Park. If we open the doors to this zoo of extinct creatures, what would you expect the dinosaurs to look like behind it? To those who have read or seen Jurassic Park, it may have been the picture of a dinosaur. Your perception can be swayed by horrific scenes of park rangers turning into light meals, or the iconic melody of the movie theme can resonate in your head as it envisions herds of long-necked beasts marching across the land. The excitement of this dinosaur park is undeniable. But can a Jurassic Park really happen?
When Michael Crichton first came up with the Jurassic Park story in the late 1980s, one of his last things was perhaps the most significant. Got the DNA in history needed to create a dinosaur theme park? This would be the key to the whole plot, which would give the story a sense of scientific realism. According to an interview with paleobiologist George Poinar, Jr.In an interview with Science Friday, the 1982 article published in Science magazine referred to a fly found preserved in hardened tree sap and that the fly at the end of its life somehow got rid of the resin during this period.
Not only was this the stroke of genius that led to the creation of this fictional land, it was a real discovery. Together, the story of Jurassic Park and the science at the center of the story would inspire the next generation of paleontologists and open the world’s imagination to dinosaurs.
What might fascinate humans most about dinosaurs is the multitude of unanswered questions with only hints of their premodern dominance. What were dinosaurs really like, and how did their unique appendages help them as they roamed the world? end up in different groups?
Since humans have never lived with dinosaurs, no one has the answers to some of the questions. We are learning more and more about dinosaurs as scientists discover and research more and more fossils. Scientists have discovered more than 700 species of dinosaurs around the world.
Scientists are now working to reverse extinction by bringing animals back into our lives that disappeared long ago from Earth. By manipulating the genetic code in the DNA of the closest living relatives of extinct animals, scientists can slowly build and manipulate a model of the species. DNA. One of the most famous cases is that of the woolly mammoth, which died about 4,000 years ago. Mammoth DNA is preserved in the frozen soil of Siberia, so scientists are working on a project to combine these fragments of the genetic code with that of living things. Elephants It may take thousands of years to separate these species, and more than 60 million years for dinosaurs, but if scientists can succeed in producing these extinct species, this could be a stepping stone to the start of a true Jurassic Park.
Have We Found DNA Of Dinosaur?
The biggest hurdle we have to overcome before we can create a dinosaur park is to get the main ingredient. Without access to dinosaur DNA, researchers cannot clone real dinosaurs. New fossils are discovered in the ground every day. provide important evidence for the shape of a species, its organic material has long since disappeared. Instead of bones, dinosaur fossils are made up of rocks and sediments that have filled the bone’s place.
While these clues can tell us something about the shape and size of a specimen, its lifespan, and the unique characteristics of the animal, it cannot give us the critical genetic information it contains dinosaur DNA, according to a study published in the journal National Service Review Published: Many paleontologists are skeptical of this claim as it is believed that it is impossible for the protein in these molecules to survive for millions of years, according to an article published in the conversation. Cretaceous Hypacrosaurus-type cartilage is more than 70 million years old, but it has become calcified and petrified, which may have protected the inside of the cells.
Could We Make A Dinosaur?
So will it be possible to revive an extinct dinosaur? It’s something scientists are trying to figure out, although the process would be very different from what is portrayed in the films. We found signals for DNA and that small fragments can be left behind, but not enough to make a dinosaur. We can get collagen and some dinosaur proteins, but not all of the stuff we need, ”paleontologist Jack Horner told How It Works Magzine. What to do would be to grow it in a test tube because we have no idea how big the embryos of all dinosaurs are. ”The eggs are as big as ostrich eggs, but for a tyrannosaurus we think they’re a much longer and bigger . It’s like thinking of putting a human embryo in a squirrel.
Horner is the real paleontologist who inspired Alan Grant’s character in Jurassic Park.”Since finding his first dinosaur bone at the age of 8, Horner has excavated the first dinosaur embryos, the first dinosaur eggs in the western world, and discovered and named the Maiasaura dinosaur species. He was also a consultant in paleontology for” Jurassic. “Park . “
And while he thinks the cloning process is pure fiction, that hasn’t stopped Horner from getting the dinosaurs back. “In fact, I have a lab we’re trying to figure out how to make a dinosaur,” he said. How It Works, one Sister site of Live Science. “It’s called the Dinochicken Project and it’s mostly based on genetic engineering. The idea is to use atavistic genes. They are basically ancestral genes, which means that ancestors programmed certain traits. For example, children will occasionally have additional Vertebrae are born and form a low tail that the doctor easily identifies when the child is born. And from time to time snakes with small appendages are born.
Horner’s plan is to use the atavistic gene.”I was hoping that some of the properties of a dinosaur in a bird would be atavistic. All bird species are related to each other, with a common ancestor, dinosaurs, so any bird should work. Chickens are the thing. Easier to get eggs, so I built in Lab, hired some geneticists and developmental biologists and started to see if we could find some of these potential atavistic genes, “he said,” he added.
“We found that reducing the tail from a long-tailed dinosaur to a short-tailed bird is not an atavistic gene. We are trying to find out how the tail actually works and reverse the process that formed the short tail “.
So are we closer to making a dinosaur? “Other laboratories looked at the face, teeth, arms and hands. I think we can pretty much work the rest of the body.We have the potential to create an animal that has a head similar to that of a dinosaur, probably with teeth, and we certainly have the ability to flip its wings to form arms and hands. We know we can, but right now we’re just trying to fix the tail, ”said Horner.
Let’s follow the Jurassic Park method to extract DNA from dinosaurs and decipher the true science of fiction.
- The trapped mosquito
Amber is petrified tree sap that is known to hold onto small organisms. he died from the hardening of the resin around him or was completely covered in resin shortly after his death. Embedded in sediment, the resin hardens under extreme pressure and heat. Amber dehydrates the body inside, which slows its breakdown. it also serves as a protective cover and when hardened creates a perfect imprint of what is trapped inside.
Insects are small enough to be encapsulated, but how would a dinosaur’s DNA get into this resin? The idea behind the mosquito in “Jurassic Park” is that you only have to preserve the genome of the dinosaur.Mosquitoes existed at the same time as dinosaurs, and it is possible that a mosquito with dinosaur blood was trapped in the resin; However, over time, the blood will break down, and scientists have found that it no longer conserves DNA as well as outer tissue.
- Cell Survival
Bones and teeth are relatively common finds when hunting dinosaurs, but what about the soft tissue needed for cloning? Soft tissue, which contains living cells filled with genes, is the first to disappear when fossils are formed. accept that soft tissue survival was impossible for millions of years, but in recent years unlikely discoveries have suggested otherwise. In 2005, molecular paleontologist Mary Schweitzer discovered small amounts of protein in the leg of a T. rex in Montana, showing how new discoveries can redefine the possibilities.
- Making Strand
In order to clone an animal with the same physical characteristics, it is necessary to obtain a complete genome. Collecting this information can be easy from animals that are still alive or have recently died. was discovered today in small fragments. This is due to a combination of ultraviolet light, cosmic rays, and enzymes that break down proteins.
- The Frog Addition
The DNA source is likely incomplete, is there any way to replace the existing material? Without further shipments of dinosaur DNA, the Jurassic Park story is about finding the missing fragments with DNA Replace frog. The use of frog DNA was critical to the population control property. Some species of frog can go through a biological change from female to male. to reproduce when their species is threatened. This trait was passed on to dinosaurs.
Since frogs are actually amphibians, they are completely different from dinosaurs and their DNA is not similar enough. Birds, on the other hand, are descended from dinosaurs and can have considerable similarities. The best hope for paleontologists trying to bring back dinosaurs is to wait until a large, well-preserved sequence of DNA is found.
- MAKING COPIES
One method by which multiple copies of small pieces of DNA can be made is through the polymerase chain reaction. , a strand of DNA can be copied, creating millions of identical strands and providing a sample large enough to analyze and sequence the order of the amino acids.
Living With Dinosaurs
If humans could save dinosaurs from extinction, how would we live together? If dinosaurs weren’t extinct, it would be unlikely that humans would have been able to evolve. During the 150 million years that dinosaurs existed, mammals lived next to them, but these animals were nocturnal and lived in caves. This suggests that this was the only way mammals thrived alongside dinosaurs and appeared mainly at night to hunt. Since our lives are completely separate from that of the dinosaurs, there is no way of knowing what would happen if dinosaurs lived on the same earth as us.
Looking at human behavior with today’s large predators, it seems unlikely that the two species coexisted naturally. Humans occupy so much space on the planet that the introduction of predators like dinosaurs from captivity is likely to result in a battle for land.
Horner disagrees, however. “People always say, ‘Where are you going to put these dinosaurs when you’re making them?’ and I always say that we started with wolves thousands of years ago and now we have Chihuahuas, ”he said.“Dogs are basically wolves and we don’t really need to contain them. I wouldn’t expect dinosaurs to be the same as dinosaurs in Jurassic Park. They’ll be pets we don’t have to worry about about. If you were to clone a real Tyrannosaurus, you would have to worry about containing it. Dogs and cats were wild but now we don’t have to contain them anymore.
The problem of recreating a dinosaur has been overcome, could we keep them alive? compared to 21% today, according to New Scientist. However, this number is believed to have changed significantly during the dinosaurs’ long time on the planet, so that some species would adapt better to our air than others found that global temperature would have been much higher than it is today than dinosaurs Roamed earth, according to the National Oceanic and Atmospheric Administration.
An island in a tropical region of the world would be the best option to provide temperatures that many dinosaurs would be comfortable in, and when it comes to containing them the park should look very different from what it did in the movie. . “If you really want to build a Jurassic Park, and not just make a movie, you want walls around the dinosaurs to support them.” Horner told How It Works, “Reinforced concrete will work much better than electric fences because the electricity can be turned off. Electric fences weren’t a good idea.
