As you may know, frozen woolly mammoths have been discovered in ice formations, more or less intact, since the 18th century. So why not clone some, bringing them back from extinction?
A Russian university says scientists have discovered frozen woolly mammoth fragments that may contain living cells deep in Siberia, bringing closer the possibility of cloning the extinct animal.
The North-Eastern Federal University said in a statement on Tuesday that an international team had discovered mammoth hair, soft tissues and bone marrow at a depth of 328ft (100m) during a summer expedition.
Expedition chief Semyon Grigoryev said a group of Korean scientists with the team had set a goal of finding living cells in the hope of cloning a mammoth. Scientists have previously found bodies and fragments, but not living cells.
