The pioneering scientist who created Dolly the sheep has outlined how cells plucked from frozen woolly mammoth carcasses might one day help resurrect the ancient beasts.The notional procedure – bringing with it echoes of the Jurassic Park films – was spelled out by Sir Ian Wilmut, the Edinburgh-based stem-cell scientist, whose team unveiled Dolly as the world's first cloned mammal in 1996.Though it is unlikely that a mammoth could be cloned in the same way as Dolly, more modern techniques that convert tissue cells into stem cells could potentially achieve the feat, Wilmut says in an article today for the academic journalism website, The Conversation."I've always been very sceptical about the whole idea, but it dawned on me that if you could clear the first hurdle of getting viable cells from mammoths, you might be able to do something useful and interesting," Wilmut told the Guardian....

Contrary to their hunting reputation, Stone Age Siberians killed mammoths only every few years when they needed tusks for toolmaking, a new study finds.People living between roughly 33,500 and 31,500 years ago hunted the animals mainly for ivory, say paleontologist Pavel Nikolskiy and archaeologist Vladimir Pitulko of the Russian Academy of Sciences. Hunting could not have driven mammoths to extinction, the researchers report June 5 in the Journal of Archaeological Science.On frigid tundra with few trees, mammoth tusks substituted for wood as a raw material for tools, they propose. Siberian people ate mammoth meat after hunts, but food was not their primary goal....
