Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?

On the mythical site of Saqqara, the Apis bulls were buried for more than a thousand years in the immense underground necropolis of the Serapheum. Discovered in 1850 by the French Egyptologist Auguste Mariette, this place shelters a treasure of which a part is preserved in the Louvre. The collapse of the ceiling of one of the galleries had however prevented the archaeologist from venturing into the entire necropolis. More than 170 years later, the museum's Egyptologists are continuing the work of their famous predecessor. Investigating the cult of the Apis bull and the mysterious rituals that surrounded it, the team is especially looking for access to the unexplored parts, which have at least eight burial chambers, with the hope of finding intact tombs.

Huelva, Spain, an isolated region lost in time. The grass, the sand and the sky are the same that those foreigners saw in the spring of 1895, when they crossed the sea from a distant country to mark the unspoiled terrain and extract its wealth, when the tower was new, when people could climb to the top of the highest dune and imagine that the city of Tartessos was still there, in the distance, almost invisible in the morning brume.
