One of the extinct animals long before the modern human society formed might walk on the ground again, thanks to an experiment like that in a Hollywood movie.
Cave lions, the largest lion species that ever lived on Earth, may fall into extinction due to human hunting by the skin during the Stone Age.
From DNA samples taken from intact frozen baby lions after 12,000 years, international scientists are hoping to revive cave lions that once wandered on Earth in the Ice Age.
Under the thousand-year-old ice of Siberia, the corpses of the young cave lion are still as intact as they were when they were full of feathers, skin and internal organs.
