WASHINGTON – Scientists for the first time have unraveled much of the genetic code of an extinct animal, the ice age’s woolly mammoth, and with it they are thawing Jurassic Park dreams.
Their groundbreaking achievement has them contemplating a once unimaginable future when certain prehistoric species might one day be resurrected.
“It could be done. The question is, just because we might be able to do it one day, should we do it?” asked Stephan Schuster, the Penn State University biochemistry professor and co-author of the new research. “I would be surprised to see if it would take more than 10 or 20 years to do it.”
The million-dollar project is a first rough draft, detailing the more than 3 billion DNA building blocks of the mammoth, according to the study published in Thursday’s journal Nature. It’s about 80 percent finished. But that’s enough to give scientists new clues on the timing of evolution and the deadly intricacies of extinction.
The project relied on mammoth hair found frozen in the Siberian permafrost, instead of bone, giving biologists a new method to dig into ancient DNA. Think of it as CSI Siberia, said Schuster. That different technique — along with soaring improvements in genome sequencing and the still embryonic field of synthetic biology — are inspiring scientists to envision a science-fiction-like future.
