Jurassic Park is coming to life because scientists have ambitious plans to bring back extinct animals.
Is An Actual Jurassic Park Possible?
There is an ambitious plan to bring back extinct beasts using their DNA. Scientists are working on bringing to life some of the animals that didn't survive million years ago, Daily Mail reported.
They are contemplating bringing back the Tasmanian tiger, woolly mammoth and dodo. However, Tyrannosaurus Rex's return is unlikely.
The outlet noted that through science, experts are working on recreating extinct animals using stem cell technology, cloning or breeding back.
Breeding back is a form of artificial selection involving the intentional selective breeding of domestic (but not exclusively) animals in an attempt to create an animal breed with a phenotype that resembles a wild-type ancestor, typically one that has become extinct, according to DBpedia.
It should not be confused with dedomestication. A breeding-back breed may resemble an extinct wild type in phenotype, ecological niche, and to some extent genetics, but the gene pool of the extinct wild type was different. Even the superficial authenticity of a bred-back animal is contingent on the specific stock used to establish the new lineage. According to the literature, some breeds, such as Heck cattle, are at best a vague resemblance of the extinct wild type aurochs.
Meanwhile, cloning uses the organism's DNA to produce genetically identical copies of the animal or plant. There are three types of artificial cloning: gene, reproductive, and therapeutic.
Gene cloning creates copies of genes or parts of DNA. Reproductive cloning results in creating copies of whole animals. Therapeutic cloning produces embryonic cells to replace injured or diseased tissues.

What Are The Extinct Animals That Scientists Plan To Bring Back?
Scientists are planning to de-extinct a number of animals, including dodo that went extinct in 1662, the wolly mammoth that breathe its last 10,000 years ago, and Australia's Tasmanian tiger that went extinct 3,000 years ago.
The experts are also working on bringing back the Christmas rat that went extinct between 1898 and 1908, Pyrenean ibex (2000), Aurochs (1600), and Southern gastric-brooding frog (1983).
There are probably many who are excited about seeing real-life dinosaurs, which are heavily featured in Jurassic Park movies. Unfortunately, it is unlikely to happen.
In the 1993 movie, scientists resurrected dinosaurs using the DNA-filled mosquito preserved in amber for millions of years. However, the outlet noted that when amber preserves things, it only preserves the husk, not the soft tissues so there's no blood preserved inside mosquitos, which was shown in the film.
While it's possible to find blood residue inside ancient insects, it doesn't guarantee that there will be DNA in them to bring back dinosaurs because over time, exposure to UV light breaks down DNA into short fragments. So, there is no chance of seeing dinos walk the Earth again.
