De-extinction has been discussed for a long time now and is the process of bringing an extinct species back to life. It has been portrayed in some sort of way in movies and media. For example, as seen in Jurassic Park, dinosaurs are the main animals in the movies, but as we know today they have been extinct for a long time. Although it has been discussed for a while, people don't realize the negative effects of bringing an extinct species back to life. They are extinct for a reason, right? So why try and bring them back to life and cause chaos in nature? Scientists would also have to focus all their attention on doing this and not focus on preserving existing biodiversity and species. De-extinction will have setbacks and has too many downsides …show more content…
That species is extinct, so how would they obtain the DNA needed? Technology is an issue because we don't have it yet. In the text Bringing Them Back to life, the author writes “For most of that time the science of de-extinction has lagged far behind the fantasy”. This quote is a prime example of why de-extinction should not happen, because it’s saying that we are far behind the technology needed in order for de-extinction to occur. Another reason is that the author says “the only species we can hope to revive now are those that died within the past few tens of thousands of years and left behind remains that harbor intact cells”. This quote is another example of why it shouldn’t happen because there is a slim chance that archaeologists will find extinct species with enough intact cells to use. If they focus on finding enough DNA to use and then realize it won’t work, they have now spent a lot of time searching for DNA that doesn’t work. In all of this time, they could have been focusing on preserving existing species to make sure they don’t go extinct. De-extinction is not worth it because species that are brought back will need lots of attention in order to live a good
Michael Crichton’s classic novel Jurassic Park sparked controversy among scientists, excited science-fiction fans, and captivated paleontologists as Chrichton proposed the idea that dinosaurs could be cloned. The plot elicited criticism from scientists around the world, but support from others. Cloning a dinosaur was made possible in the fictional text: take some amber, fill in missing DNA, obtain an ostrich egg, keep the egg in a controlled environment, then a dinosaur is born. Unfortunately, each of the steps are of intricate design.
Humans have driven many animals extinct, but should we bring them back is the question. Geneticists, biologists, conservationists and ethicists gathered to discuss the controversies. Some people say in doing this we are playing God, while others say we did by killing them. Other scientist say that it may be beneficial because it will add biodiversity, and medicinal properties back to the ecosystem. It is only possible to bring species back from around 10 thousand years ago. Recently scientists have vastly improved the cloning process. We can now coax adult animal cells into any type of cell, including eggs and sperm, then manipulating them into full-fledged embryos, which has led to the ideas and developments of reviving many other species including mammoths, frogs and
Of course it was the movie Jurassic Park who seemed to coin the phrase “Dino DNA.” This movie gave the public the thought that, a) it is possible to find dinosaur DNA and b) we can clone dinosaurs from this DNA. This essay is not going to pick apart Jurassic Park’s scientific value, however it will share the current knowledge and information on dinosaur DNA. The discovery of DNA is important because it may uncover different bits of information. The idea of cloning dinosaurs, especially at this point is out of the question. It is really hard to clone living animals today, with full DNA and genome strands, we can’t even think about recreating animals millions of years ago.
Human extinction may occur because of many reasons some may include because of how we take care of our planet and what lives on it. Another may be because of a disease or a fungus we may spread to one another and will not be able to gain control over it. Instead if we try to save what is left our species may go even further and we may be able to live longer. Our own comfortable lives and not really affected as they should be because most people do not care what is going on outside of their own lives. They should be more concerned because it does involve them, they are part of the human
Through the use of appeals to logos, ethos, and pathos, the author attempts support his claim that humans have an obligation to revive species which have been driven to extinction directly due to human influences. Though the author establishes his credibility to the audiences in agreement with his claim , the author’s use of fallacies within his arguments proves that the article lacks credibility. Therefore, the argument that humans have an obligation to revive species which have been driven to extinction directly due to human influences is ineffective and not a credible argument.

One prominent flub that is witnessed throughout the duration of the film, besides the fact that most of the dinosaurs are from the cretaceous period, is the fact that it remains impossible to bring dinosaurs back to life. Dinosaurs are extinct! They have been extinct for 65 million years. True, one would need dinosaur DNA to recreate dinosaurs, and it is indeed possible for mosquitoes with the DNA of dinosaurs to have been trapped in hardening amber, as seen in the film. However, it is impossible for scientists today to find hardened amber with dinosaur DNA in it, simply because DNA does not last; it degrades over time (even in preserved amber). Just the tiniest bit of degradation would ruin its value (UCMP 1995). Therefore, you would not have the starting point for proceeding with such an endeavor as the scientists inaccurately accomplish in Spielberg's film: the breeding of dinosaurs.
The path from finding and sequencing suitable DNA, as well as providing a host for growth and a suitable environment for it to function is beset with many obstacles. Maybe after decades of extensive research in each of these areas, such a project as recreating a dinosaur may be attempted, but most scientists agree that their"extinction is permanent" (Paabo, 1993). Thus, cloning dinosaurs or any ancient organism, remains a frontier of the future. However, as David Grimaldi writes, "While it is a long way from amplifying a bit of DNA to reconstruct a whole dinosaur - or even a termite - these new developments open up many exciting scientific possibilities" (1993).
Over a century ago, humans fought animals for dominance of the landscape and we regrettably won, now they’re in need of our protection. The Government and Organizations have come to the rescue of wildlife species all across the U.S. Their main goal is to protect wildlife species from over harvesting and also their loss of habitat due to industrial and residential development. The beauty and curiosity of wildlife captivates all of us for different reasons. For certain species, they are the link to our existence Animals are not being hunted into extinction because the government is protecting certain wildlife areas and are controlling the animal populations within those certain areas. While increasing a wildlife species population and removing from the endangered species list, a predator such as the gray wolf, is sure to be seen as a success to some and a threat to others.
Who wouldn’t want to see a Wooly Mammoth traipsing across the tundra, or see witness and laugh at the odd sized Dodo Bird? Although the spectacle of witnessing such animals is certainly fascinating, it is this attitude that makes the practice of de-extinction, in my opinion, morally incorrect. Reviving a species solely for entertainment purposes is inhumane. And due to the fact that releasing a revived species into the wild could be disastrous, the animals would have to reside in zoos, where humans could gawk at them for the rest of their lives. And if they escaped, well, we might have a Jurassic Park situation in our

De-extinction is a process that has been experimented with for many years, but has never been completely successful. The ethics and consequences of this idea have been questioned but, de-extinction has the potential to be truly helpful to humans and the environment, and many of the scenarios that people think could happen, are actually impossible. To actually revive a species, there are certain conditions that must be met, and the terrible situations that people think could happen, are unable to actually occur because of the lack of . Bringing species back that are beneficial to the environment could preserve biodiversity, restore diminished ecosystems, advance the science of preventing extinctions, and undo the harm that people have caused in the past. The true potential of the revival of species cannot be realized because people overdramatize the effects and possible outcomes. Once we realize and understand how beneficial the process of de-extinction can be we can better improve our world, our lives, and our ecosystems.
In the play Oedipus Rex by Sophocles, Tiresias is demanded by Oedipus to speak of the source of which Teiresias has received his predictions, Teiresias’s response is, “[y]ou weave your own doom”(Sophocles, 1.162). This idea of “weaving your own doom” is found throughout Oedipus Rex mainly as a theme of characters past actions can and will affect their future, their future being the doom the face. This not only is found with Oedipus but other characters, it is a common event that takes place throughout. Firstly, what is doom?
So what is an endangered species? What is an extinct species? What has happened to cause them to become endangered or extinct? What needs to be done in order to save the endangered species from becoming extinct? Can anything be done to save them? The answer to most of these questions is not known by everyone. With all the attention that this subject gets from the government or groups that fight for the environment, it gets the same amount of disregard from the public. Many people want to help or donate but very few of those actually follow through. This is a very important subject that needs to be taken serious by the public. It needs their full attention because they are the ones that can truly make a change. People really don’t understand the concept of extinction. If somethi...
The Lazarus Project team were able to recover cell nuclei from tissues gathered in the 1970s that were kept for 40 years in a conventional deep freezer. After repeating experiments for 5 years researches used a technique known as somatic cell nuclear transfer. To complete this, scientists used fresh donor eggs from a distantly related Great Barred Frog. The egg
