The last mammoths died about 4000 years ago, and the passenger pigeon vanished around 1900. How ethical would it be to specifically create an animal that would be used for monetary gain or research purposes? It will be a very large obstacle to begin this type of testing, mainly because of the problems that already exist with animal cloning. Many families have greatly suffered because they lost a pet. Development Of New Diseases By bringing in an entirely new group of people, that we have no experience or research on, we could be introducing many things into the human race. Cloning has become a highly controversial topic in the world in recent years. After their extinction, these healthy natural disturbances ceased, white oaks lost their primary mode of seed dispersal i.
Sure, we have Jurassic park, but how factually correct is is? It seems a little strange to attempt to bring back already extinct animals instead of helping the current ones. Their numbers were so great and their droppings so prevalent and flammable that they destroyed trees and increased forest fires. Cloning requires advancements used for attaining a perfectly cloned animal, the cost is higher than the usual costs of natural propagation. On the moral aspect in particular, it is considered as an act against God, who is believed to be the creator of all things, animals included. It is this level of curiosity and amazement that has many people excited about these possibilities. The advantage of such an approach, Kerkdijk-Otten says, is that it would utilize cattle already adapted to the world's present ecology, rather than trying to re-create an animal from a different time and climate.
Once the trait is cloned into multiple animals, it has a much better chance of becoming a dominant trait in the herd. The huge amount of money that we are spending on de-extinction could be used to save species which are on the verge of extinction. The researchers are continuing their frog cloning attempts. People who have the money and the desire to bring back to life their beloved pets can now do so with this scientific breakthrough. However, some experts and conservationists don't think cloning is an effective strategy in the preservation of an animal species, as the University of Utah reports. This is because it has its merits and it can help humanity in several ways. List of Cons of Cloning Extinct Animals 1.
If we were to bring these animals back to the planet for scientific study, we would be able to connect important links in the evolution of animals, and possibly even man. In 1914, the very last known passenger pigeon died in the Cincinnati Zoo. The debate is become more and more heated as the headlines begin to fill the news. Genetic diversity is reduced — since it is possible to create identical copies of animals, this aspect is reduced greatly 6. By cloning, men oppose the normal course of nature and take the role of God. List of Advantages of Cloning Extinct Animals 1.
In fact, this has been done successfully multiple times. As varieties offer different disease-resistance levels, diversity protects crops from susceptibility to one disease which could wipe out a species worldwide. The Advantages The following are the advantages of cloning animals: 1. This helped lay the foundation for modern cloning technologies. They are some rather scary looking creatures. The world has changed a lot and bringing an extinct animal back to this period may not really bode well for them and us. It goes against the normal course of nature by taking the role of God.
In the case of mammoths, scientists might try to mate Asian elephants with more body hair than usual, for example. If done successfully on animals, scientists and mankind might be looking at a future where stem cells in humans can be cloned to produce identical stem cells for specific people for future use. The process was done through somatic cell nuclear transfer. Moral questions are also raised when talking about de-extinction. The code is the set of instructions for making the animal's body. We will also be able to eradicate diseases that are caused by specific genes by introducing immune species in the wild.
Spread On The Best Characteristics Just like humans, some animals have better traits than others of their same species. With continued research, it may be possible to create identically similar animals, or even humans! While it is surely an amazing feat for the scientific and medical communities, the back lash has slowed this research dramatically. List of Advantages of Cloning Animals 1. A species with high genetic variety has a higher chance of including individual animals with the capacity to survive drastic environmental challenges, such as contagious diseases. In reproductive cloning, however, it would become 100%. Bringing back an extinct animal can offer important scientific knowledge.
It could help medical science. Whereas a few years ago scientists thought that recreating extinct species was an impossible task, some are now saying that it may be within the realm of possibility in the not-too-distant future, at least for some species. It is the reproductive cloning process which produces a genetically identical animal. Animal Breeding Tool Cloning would give breeders the power to breed different breeds and species without the risk of the offspring being weak or unhealthy. There are benefits as well as potential drawbacks in cloning animals. Is this a course of action that scientists should pursue? Morals For those who believe in god, they feel that man is taking things one step too far by trying to become a creationist and controller of all species in the world. This perhaps triggered the controversial pet-cloning industry with owners willing to spend thousands of dollars to bring their departed pets back to life.
A Little Redemption In many cases, the reason that these species became extinct in the first place is because of the impact that humans had on them. Moreover, people are concerned of the ethical and moral effects of cloning. The process however can take time and several steps to accomplish. I think it is a dangerous path. There have also been disasters, like the poisonous in Australia, which was originally imported to help control the gray-backed cane beetles that were damaging sugar crops, but is now spreading across the continent and depleting native populations.
Archer hopes that reintroduced thylacines would break up Tasmanian devil populations in a helpful way. This make it so that the appearance of a donor and a clone may not always be identical. By bringing back an animal we could, in theory, be giving it a second chance to thrive and undo some of the damage that we have previously caused. Reintroduction Of Bacteria When thinking of the possibility of extinct animals being reintroduced to the earth, one big problem arises. This would also allow for prize animals or superior animals to be cloned and help spread their beneficial traits to more of the species population. Would it be possible to manage those risks effectively? This is what most opponents of cloning are most concerned about. He points to research that shows that mammoths and other large herbivores trampling across the ancient Arctic ecosystems helped maintain the grasslands by knocking down trees and spreading grass seeds in the dung.
