Clark Schultz writes: The premise behind Jurassic Park just got a bit realer after scientists in South Korea said they are optimistic they can extract enough DNA from the blood of a preserved wooly mammoth to clone the long-extinct mammal. The ice-wrapped wooly mammoth was found last year on an island off of Siberia. The development is being closely-watched by the scientific community with opinion sharply divided on the ethics of the project.
