Could Jurassic Park really happen?Upnoru10 - 6 Answers
In the movie Jurassic Park, dinosaurs were cloned using DNA gotten from insect remains found preserved in fossilized tree sap or amber. Specifically they used the blood from the guts of preserved mosquitoes as a source of DNA. There are several reason why this technique to get cloneable dino DNA would not work and the chances of finding any useable DNA from dinosaur fossils are very remote, but you never say never when it comes to science, especially the science of life.
The idea of getting dino DNA from an insect preserved in amber, has all the odds stacked against it. First the bug would have to have fed on a dinosaur and then been caught in the tree sap right away so its digestive juices could not break down the DNA, second DNA breaks down very rapidly in the presence of moisture and once trapped in the tree sap, the bug would not dry out rapidly. Then there is the fact that the insect fossilized in amber has to be from the age of the dinosaurs and it has to be the right kind of insect that fed on a dinosaur, both of which are very rare. Lastly we have to be lucky enough to find that rare dino skeeter and be able to extract Dinosaur DNA from it that hasn't been contaminated with the bug's own DNA.
Other sources of DNA would be the actual remains of dinosaurs themselves such as their bones, but when these bones are petrified their chemical makeup is replaced by minerals from the soils and rocks they are buried in when preserved.
No verifiable soft tissues from a dinosaur have ever been found, though in 2005 researchers found what they believe to be blood vessels and whole cells in the leg bones from a Tyrannosaurus rex fossil. They still have not been able to extract any DNA from whatever it is that they found. Even if DNA is found, the chances of it being enough of an entire DNA strand to be able to clone a whole new animal are small. Individual DNA strands are made up of billions of individual sections that form the codes for building a new organism. And even if a full strand of intact dino DNA is found, we still have to come up with a suitable incubator ie: an egg, for it to develop in, with no idea of what kind of egg it would take.
All in all the likelihood of someone coming up with a cloned dinosaur, is pretty remote. We might be able to clone more recently extinct species like mammoths or animals we wiped out in the last few centuries by extracting bits of DNA from frozen carcasses, dry remains, or museum specimens. Then by inserting it into their close living relatives we could breed hybrids and by recrossing them finally come up with a 99% pure species.
Jurassic Park probably could not happen. No matter how good the cloning technique, the parts of dinosaurs available has been fossilized, which means they are no longer pieces of flesh or bone from which a DNA sample could be drawn.
It may be more likely that cloning of a frozen mastodon, or some other frozen beast or plant, could be possible at some future time. Parts of the recently extinct Dusky Seaside Sparrow have been frozen, in the hope that it may someday be possible.
Most extinct animals from the past few hundred years, are probably so dried out (and are just skin, hair and feathers), that a useful DNA sample would not be found.
The USDA has the National Animal Germplasm Program, with preserved frozen sperm, eggs and DNA, to be able to reproduce livestock that may die out:
Humans already use this technique of freezing eggs and sperm, and are successful in giving birth to the results of the fertilization. Cloning is a bit harder to do, with good results, than cryogenics, so any recreation of extinct life will have to wait a while.
As terrifying as it would be to see a real life Jurassic Park happen, I think nothing is out of the question anymore, especially in this day and age. Here's to hoping a real-life Jurassic Park never does happen, and also that the answer and explanation I just read above from Studoi84 for why it cannot happen is spot on.
Scientific explanations aside, I would not put anything past anyone in this world, especially with the alarming rise of technology in the last two decades, and the ridiculously fast rate for which it has advanced. I'm hoping no one even has the thought to try, but I'm sure it may be a little too late for that notion at this point in time.
Who knows, someone could've already figured it out, and maybe it's just a big hush hush secret. Isn't it funny how much conspiracy theories have grown and become more familiar right alongside advancements worldwide in science and technology? Maybe it's because the %1 are the only ones that are in the know about what really goes on behind closed doors, especially in scientific and military related developments and advancements.
The now extinct gastric-brooding frog disappeared about 30 years ago. In 2013, an Australian research team in their "Lazarus Project" at the University of South Wales, took frozen tissues from the extinct frog and implanted them into the nucleus of a dead cell in a host egg from a related species. Scientists were successful in creating embryos. The embryos did not make it to tadpole stage, but it is thought that with minor technological adjustments, they will mature to the once extinct frog.
At a March, 2013 forum called TEDxDeExtinction in Washington, D.C., researchers talked about reviving extinct species. Likely candidates for "de-extinction" include:
- Passenger Pigeon
- Woolly Mammoth
- Tasmanian Tigers
- Gastric brooding frogs
- Carolina Parakeet
- Sabertooth Cats
The cover of the April, 2013 National Geographic magazine was titled, "Reviving Extinct Species - We Can But Should We?"
Jurassic Park could happen and it's happening now. Hopefully, the outcome will be better than the one portrayed in the movie.
Yes it could, but I hope they don't because Newman would find a way to sabotage it and they would probably escape and kill a lot of people. Hopefully if people find a way to make dinosaurs, then it won't end up like the movie.
I am amazed that they have been able to clone animals. It's very amazing what science is capable of, so I definitely think it is possible.The only worry would be the fact that they eggs and bones are so old. It would prove to be a very challenging task.
Maybe that doesn't matter though, the age of the bones. I think that in the past, people might think it would be impossible to clone sheep. But, they can do that now. Jurassic Park could happen. Anything is possible.
No I don't think so. Cloning is still no where near where it would need to be to actually "clone" a dinosaur or get an exact clone of anything for that matter. We still can't even create exact clones of animals we have around today, so it is next to impossible to clone and extinct animal at the moment. Not only that, but we don't have the environment to support a reptile growing that large. The reason dinosaurs grew so large back when they were alive was because of the climate of the Earth, and now that it has significantly cooled off and the environments have changed so much, it would be very doubtful that they would even grow anywhere near their original size....
