Jurassic Park Evolution

As biotechnology continues to advance, a matter that interests both genetic and conservation scientists is the de-extinction of species, or the resurrection of lost species. The idea of Jurassic Park, a 1993 American film where genetic scientists created a wildlife park with cloned dinosaurs, is no longer science fiction. It is becoming an increasingly considered possibility, and with the present-day extinction rate of species higher than ever, scientists have commenced to ponder the prospect of not only conserving current species and ecosystems, but also reintroducing species that have died out in the past. The technological innovations made in the field of biotechnology have made the resurrection of extinct species a viable possibility …show more content…
Somatic cell nuclear transfer is the most common cloning method, due to Jurassic Park and Dolly the sheep. Unfortunately, the possibility of resurrecting a dinosaur is out of the question as a result of some major biological limitations. Deoxyribonucleic acid (DNA), the genetic material in organisms, naturally degrades over time and you need some intact genetic material in order for cloning. Scientists recently determined that the DNA can remain intact for no more than about 6.8 million years, but dinosaurs haven’t been around for about 65 million years. However, cloning is possible for less ancient species, and although wooly mammoths generally get the most attention, scientists are also considering bringing back other animals that might not be as popular, but are equally fascinating. The Tasmanian tiger, also known as the thylacine, is one of many species that was declared lost to world once. The thylacine is a large carnivorous marsupial that once roamed Australia, Tasmania, and New Guinea. A combination of hunting and trapping by humans is to blame for the extinction of this species in 1936. Michael Archer, an Australian paleontologist specialized in Australian vertebrates, points out that in the absence of viable cells or nuclei required for cloning, scientists have another path to bring back those species: …show more content…
It is important to note that animals are a part of our ecosystem, not only do they contribute to the ecosystem and help to balance the ecosystem, but they also have many uses in our daily lives. It is also essential to realize that ecosystems are undergoing constant change: Viruses strike, natural disasters destroy nearby communities, and species go extinct. In many instances, ecosystems carry on as they were, with some species making small modifications to their behavior to make up for the loss. Sometimes the changes are more drastic and the relationships between organisms are reconstructing. It’s a shocking thing to witness, organisms and ecosystems shifting around us, but this isn’t anything new. It’s been happening since the beginning of life. Not only are individuals attempting to restore nature to a balance that doesn’t seem to exist, but they’ve picked a rather a arbitrary point in time to return it to: the moment when people first started paying attention. The only species we are capable of resurrecting are those that we know went extinct, those large and common enough to leave fossils, and those that we watched die off. So you see a familiar cadre of de-extinction candidates on the list: mammoths, passenger pigeons, thylacine tigers. These are all big animals that we are sure used to be around because they are large enough
