Pyrenean Ibex: The Species That Died Twice
Mountain hunters prized the curved horns of the Pyrenean Ibex. Their numbers dwindled steadily until only one remained: a female named Celia. She died in 2000, crushed by a falling tree. Scientists later cloned her, but the clone survived just seven minutes due to lung defects. This Spanish mountain goat holds the distinction of being the first species to go extinct twice in recorded history.
