Cloning Mammoths

Anonym Feigling writes "For your consideration... An article over at the New Zealand Herald discusses some of the challenges a japanes team faces as it attemps to develop a system to create a clone from 20,000 year-old mammoth tissue samples discovered in Siberia. It seems to me that shortly after death, any animal's/plant's "cellular repair mechanisms" (for the lack of a better...) will fail, and thus the probability of finding a single cell with perfectly intact DNA from which to create a clone is pretty well zero. Interesting stuff, but it seems that practical considerations (think code rot) would make it difficult."
