But alive they were. “They’re definitely breathing!” says Steven D’Hondt at the University of Rhode Island, who discovered them. The presence of ancient, zombie microbes entombed deep under Earth’s surface may seem surprising, but D’Hondt and his crew would have been more surprised not to find them. Wherever we drill into the planet, we find life. And while some is zombie-like, most is not. Life underground is rich, dynamic and deeply strange. What it teaches us has important implications for our concept of life itself, not just here on Earth, but on other planets too. For centuries, nobody thought that Earth’s crust was anything other than inanimate rock. The first hint to the contrary came in 1926, when US geologists extracted water from oil wells nearly 600 … |
