Mapping The Genome
It isn't Jurassic Park but it could be. Scientists have begun to map the genome of the woolly mammoth and this has led to speculation that the creatures could be resurrected.
The easiest way to prevent extinct creatures from being created again is to simply not pay for it. The scientists have only mapped about 1% of the genome so far and would need serious funding to do the rest. Even when that's accomplished, you can't just stick that information into a big E-Z Bake Oven and pop out a woolly mammoth. They can't even do that with modern DNA much less an extinct creature. But imagine if you could. I'd pay a lot of money to bring back Rita Hayworth.
