Is Cloning of Extinct Animals Possible?

It seems researchers are close to cloning the woolly mammoth and perhaps a species of frog that gives birth to offspring with its mouth - swallowing fertile eggs then incubating them in its mouth. The frog died out in 1983. We have heard claims like this before. Personally, I believe we are a long way from being able to do this. Repairing the damage that pushed them to extinction is not sufficient to bring them back. Finding specimens with suitable preserved material is near impossible. Even the few frozen southern gastric-brooding frogs were not initially preserved with the intention of "cloning". Special techniques were not applied. It is thought improved systems like somatic cell nuclear transfer will enable creation of a living frog. Some presume this can be used on viable mammoth cells. The issue will be producing a healthy living creature. Previous research has resulted in incomplete clones: many do not live long. Most scientists are pessimistic about the poss...

Mammoth Cloning Still Not Possible

We have heard so much about how scientists are going to clone a mammoth. For many this idea remains "pie in the sky" - a lot of talk and no action. There is plenty of mammoth raw material around to do tests on. The problem is getting good DNA that can be cloned. Scientists are jumping up and down again with the recent find of a frozen mammoth in Siberia. They say this time their will be "living cells". This is very optimistic. The new mammoth will probably be like all the others. Only partial DNA will be found. Even though bone marrow has been identified this time, cloning is a long shot. No living cells have so far been found in any extinct animal, as far back as 10,000 years when mammoths roamed the Earth. There are problems in analyzing human DNA even though the human genome is known. The complete DNA of mammoths has not yet been determined. A prize is offered by the X Prize Foundation for the first cloned extinct animal. Scientists can hope I s...
