These masterpieces, dating back to prehistory, reveal an unexpected past. Before being a desert, the Sahara was a verdant El Dorado where lions and ostriches were hunted, and where complex cultural societies developed. A vast archaeological investigation is shedding light on a little-known chapter in human history: the metamorphosis of the Sahara. Using the latest investigative technologies, scientists are discovering new evidence buried beneath the sand, submerged at the bottom of the ocean, or etched in stone.22Episode 2223Episode 2324Episode 2425Episode 2526Episode 2627Episode 2728Episode 28Season 1Season 2Season 3Season 4Season 5Season 6Season 7Season 8Season 10Season 11
