The discovery of well-preserved woolly mammoth remains in eastern Siberia has raised distant hopes that the animal could be cloned. A Russian-led team of international scientists found intact cells among remains including hair and bone marrow.
In theory, the animal - which died out between 10,000 and 4,000 years ago - could be recreated if living cells are discovered among the remains. But one of the team members told Reuters news agency that was unlikely.
The remains were discovered in August, metres underground in the permafrost of the vast north-eastern Siberian province of Yakutia, reports said.
