Reviving Extinct Species: Is It Really Worth It?




The article of if extinct species, and reviving them is really a good idea is a very interesting article, not only because you can hear that the wooly mammoth can be revived and brought back to life, but also is a way to restore ecosystems, introduce possible ways to prevent epidemics, and clone people.

There is always room for failure, like it or not. The reviving process will be extremely difficult, time-consuming, and risky. There is no 100% guaranteed sticker on the idea. It may just work. Or may just be another fluke, and waste millions of dollars. Many things can go wrong. The animals may never be able to fit back into the ecosystem. The animals may immediately die.

This idea of bringing back creatures back from the dead would have been diminished as a child’s dream, but there is a greater reason behind reviving extinct species. It will preserve and/or bring back ecosystems that the animal once lived in. It will not only bring back the animals and their ecosystems, but also will allow the scientists to learn what went wrong, and how we can prevent that from happening to the same, or different     species.

Another advantage, ore use, for reviving species is that you can repopulate endangered species, like sharks. The method to revive extinct species can be implemented to clone and repopulate endangered species.

As the article says, the Tasmanian Devil have a disease, and it is possible to locate the source of the disease. The disease can then be removed, making the DNA cell immune to the disease. The DNA can be inserted into the animal, and soon, the immune population will out number the infected population, making the whole population immune.


The article relates to what we are just learning in Humanities, as the process to revive extinct species can be used to cure diseases, and make people immune. The DNA of the disease can be “deleted”, as mentioned above, and can be inserted into a human as a cure.

The process in the article can be altered, to serve different purposes. For example, the process can be used to save the human population and other animals by removing diseases. Take the SARS virus for instance. Scientists say that the SARS virus originated from many animal diseases, and “mutated” into one disease. If the method of the article is used in the animals that have a disease, then the SARS virus will never have happened, and similar ones will not happen again in the future. If one finds that an animal has a disease, then the animal can be made immune, preventing spread of the disease, and preventing major magnification, like the 2002~2003 SARS virus that led to world wide infection.



In my opinion, the article can be expanded to many ideas, and solutions related to genetics and DNA. Like I explained earlier, the method of removing a virus, then making an animal immune to that virus could have been used to prevent the SARS virus.

The cloning and reviving species is still in the Stage 2 of an idea, and is extremely expensive, but when further developed, it has the potential to work. Recently, I received a news article on scientists successfully cloning rats. It was stage 2 few years back, but now it is almost ready, and has worked in small scale. The reviving of extinct species should be postponed till a higher chance of success.
