By David Shultz Sep. Somewhere between 30 and species disappear every day, thanks largely to humans, and more than types of mammals, birds, reptiles, and amphibians have vanished since The two animals at the forefront of this discussion are the woolly mammotha hairy, close relative of the elephant that lived in the Arctic, and the passenger pigeona small, gray bird with a pinkish red breast once extremely common in North America. The last mammoths died about years ago, and the passenger pigeon vanished around
People with those concerns have the same concerns about all species — or at least the warm and cuddly ones. Anyone who signs off on that one should be denied the benefits of modern medicine.
On the benefit side, the only one that really grabs me is the cool factor. I place this the same as 1 Environmental benefits: Agree if those species were native to the area before.
Would I like to see one? Retroviruses can be filtered out. The technology to do so already exists. Only bring back those species we have caused extinction of. I work through this link, fab If we can bring them back lets do it. The list of objections seems pretty weak. They still carry the DNA of their ancestors.
Even so, if I agree or not, the truth still stands. Also, as our technology is getting better by the second, it does look like we could be seeing Jurassic Park in the best version of 3D, Real Life… xiaoyanzi The only objection that I agree with is that there may be many unforeseen consequences to bringing back certain species.
On the whole though, I think it manageable, and worthwhile, because we will learn and grow our knowledge and be able to use that knowledge save many existing threatened species by increasing their gene pool, making them stronger, or maybe even helping them adapt past whatever is causing their demise.
So even if we did bring back extinct animals the premature aging would cause them to die early on, if we were to bring them back we should further the technology before doing so.
Bringing back extinct animals would create issues in the food chain as well, because animals like the Woolly Mammoth would be predators and what ever prey they if they are brought back given if they can adapt to the change in food would already have predators so that food supply would decrease until one of the predators die off which could be the original predator.
The most talked about idea for bringing back extinct animals is cloning but there is an issue with that too because clones are a genetic replica of the original animal so what if there was only genetic samples from one gender of that animal?
If the animal is cloned it cannot reproduce with its own species. In reality it does seem like a cool idea but there are truly more cons than pros.
The money needed to resurrect these animals and to put aside safe environments for them outweighs existing endangered species that should be helped now.
The resulting animal will have some of the extinct animals characteristics, this will be repeated in subsequent generations until the extinct animal is as near to the original as possible.
However, is this the extinct animal back from the dead or a genetically engineered version? Thirdly, there are behaviour issues resulting from a freshly returned formerly extinct animal especially with a social animal such as mammoth. Social structure within these animals are honed via generations and releasing these animals would be tantamount to releasing a naive toddler into the wild and expecting them to know how to survive, socialise and thrive.The birds went extinct in North America in , but a geneticist in California now hopes to bring them back.

Still, similar questions might be raised about producing livestock in general. News Corp. is a network of leading companies in the world of diversified media, news, and information services.
