I don’t know if you’ve ever heard of resurrecting extinct species. In the past, many people thought it might be impossible, but now with the further development of science and technology, the leap of gene editing technology makes everything possible.
So what is resurrecting an extinct species? It is to create healthy and genetically active animals as the center of things, so that they can still reproduce naturally in the wild like the original animals, and can make a great contribution to maintaining the balance of the ecosystem.
Now that we know that this is very feasible, the most important thing is how feasible is it? Since 2003, European scientists have successfully cloned a Pyrenees goat for the first time, which has become a very important node. However, it is a pity that this Pyrenees goat died a few minutes after it was born. So the Pyrenees goat became the first species to go extinct twice. In Australia, Michael and his colleagues are trying to revive the stomach frog. The magic of this animal is that the female will hatch all the tadpoles in her stomach, then feed her young, and then spit them out when they mature. The latest development is that Professor Michael and his team have been able to produce tadpole embryos, but the next step has not been fully realized.
In addition to some well-known extinct common animals, there is also a hybrid extinct animals, such as the white zebra. Albino zebra and the existing zebra belong to the same species, but it needs several generations of reproduction to get the most like albino zebra. Therefore, in this process, not only cloning technology is involved, but also stem cell technology and assisted reproductive technology are needed.
After scientists have been able to clone these animals, there must be a question: can dinosaurs be revived? However, it is a pity that composite dinosaurs can not be realized, because there are extremely high restrictions on the replication of species. First of all, scientists need to have the source of animal DNA. Dinosaurs have been extinct for almost 65 million years from now. Biologists are convinced that DNA will dissipate with the passage of time. So it means that there will be no dinosaur DNA residue in modern times, so it is totally impossible to revive dinosaurs.
After so many introductions, what is the significance of reviving these extinct species? Through the research of scientists, we can see that all species play a very important role in the ecosystem. They exist together and maintain a very delicate balance. Then when some disappeared species return again, their duties will return together. For example, the mammoth that scientists want to revive most now – it can knock down saplings and get rid of weeds. On this basis, its existence can protect biodiversity, and now mammoths disappear completely, which means that biodiversity is reduced – for example, the once dense grassland has been replaced by tundra. In addition, reviving extinct species in the field of zoology is a key scientific means to reduce the harm of species extinction, because in the aspect of nature conservation, if we can reverse species extinction, it is definitely a milestone, and it is enough to further stimulate the enthusiasm of future generations and scientists to protect organisms.
Apart from resurrecting animals, most people care about resurrecting dead people. Some people oppose the resurrection of extinct species because they think it is against the law of nature; some people oppose human cloning because they think it is against morality and ethics. But in fact, according to the facts, researchers and scientists who resurrected extinct species believe that if this value can be proved through science, people’s worries will gradually disappear. But now there’s a consensus about human cloning – it’s not allowed. In addition, the DNA in the immature cells will be redefined and recombined. In this case, no one, whether scientists or biologists, knows exactly how it completes its self process. To put it bluntly, the cloned human faces are the same, but the possibility is greatly changed.
Many people are supportive of reviving extinct species. But only when scientists are fully capable of successfully resurrecting extinct species can we assess how to use this technology, or whether to use it.
