‘Closer than people think’: Woolly mammoth ‘de-extinction’ is nearing reality — and we have no idea what happens next

By Sascha Pare – LiveScience

For about seven minutes in 2003, scientists reversed extinction.

The resurrected lineage was the Pyrenean ibex (Capra pyrenaica pyrenaica), and the last known member of the subspecies, a female named Celia, had died three years earlier.

Scientists had collected DNA from Celia’s ear before her death and injected her genetic material into a domesticated goat egg cell with its nucleus removed. The resulting clone — the first and only extinct creature to have been revived at the time — died soon after birth due to a lung defect.
