Mammoth find sparks cloning hopes
Russian researchers say they have discovered a perfectly preserved woolly mammoth carcass with liquid blood on a remote Arctic island, fuelling hopes of cloning the Ice Age animal.
They say the frozen remains of a female mammoth were so well preserved that blood was found in ice cavities when they were broken up.
Semyon Grigoryev, the head of the Mammoth Museum who led the expedition, said the carcass was preserved because its lower part was stuck in pure ice.
He said the find could provide scientific material for cloning a mammoth.
Woolly mammoths are thought to have died out about 10,000 years ago.
Scientists have deciphered much of the animals' genetic code from their hair, and some believe it is possible to clone them if living cells are found.
