• Resumen

  • At the bottom of the Mediterranean Sea, just south of Greece, there is a lake. Complete with a delicate shoreline and an inviting deep blue surface, the L'Atalante basin looks almost like a lake on land. But this is an inhospitable place. Its waters are about as salty as water can be and never mix with the layers above--making it completely devoid of oxygen. It was a shock, then, when biologist Roberto Danovaro scooped up samples from the bottom of this briny pool and found a thriving community of microscopic animals living there. The discovery went against everything they thought they knew about animal life and its reliance on oxygen. Here, Barras investigates whether complex life could evolved without oxygen.
