As use-by dates go, this meatball is just a few thousand years past its best. That’s because it contains the resurrected flesh of a woolly mammoth — a beast that went extinct some 10,000 years ago.
The prehistoric meatball was made by an Australian cultivated meat company that ultimately wants to mix and match cells from unconventional species to create new kinds of meat.
Scientists took the DNA sequence from a mammoth muscle protein and filled in the gaps with code from an elephant, the species’ closest-living relative.
This sequence was then placed in the myoblast stem cells from a sheep, which replicated to grow 20 billion cells that were in turn used to grow the mammoth meat.
However, despite creating what they hope will be a ‘really tasty’ meat, the experts are too afraid to eat it in case the ancient protein proves deadly.
