Live Science: Scientists with the Mammoth Creation Project hope to find a frozen woolly mammoth specimen with sperm DNA. The sperm DNA would then be injected into a female elephant; by repeating the procedure with offspring, a creature 88 percent mammoth could be produced within fifty years.
"This is possible with modern technology we already have," said Akira Iritani, who is chairman of the genetic engineering department at Kinki University in Japan and a member of the Mammoth Creation Project. However, the DNA in mammoth remains found to date has been unusable, damaged by time and climate changes. "From a geologist's point of view, the preservation of viable sperm is very unlikely, and this is so far confirmed by the poor condition of cells in the mammoth carcasses," said Andrei Sher, Russian paleontologist and mammoth expert.
Woolly mammoths became extinct about 10,000 years ago as warming weather reduced their food sources. Although only about a hundred specimens have been found, as many as ten million mammoths are believed buried in permanently frozen Russian soil.
Irtani has already picked out a preserve for living mammoths in northern Siberia; this "Pleistocene Park" would feature extinct species of deer, woolly rhinoceroses and maybe even saber-toothed cats, along with the mammoths.
In his novel Jurassic Park, Michael Crichton popularized the idea of using dinosaur DNA taken from mosquito-like insects trapped in amber to create a Jurassic Park of recreated dinosaurs. Unhappily for the Pleistocene Park planners, both books and all three movies ended badly for most of the participants, including the investors. Also, astute scientists are already pointing out that these experiments would merely create mammoth-like creatures, not mammoths themselves. This wasn't pointed out until the third movie in the Jurassic Park series.
