• Resumen

  • Early Earth may not have been as hot and hellish as people thought, and the planet may have been in a deep ice age when life first emerged. This is according to an analysis of rocks from South Africa that formed about 3.5 billion years ago, during the Archaean period. Previous research suggested that the ocean in which these rocks formed was hot--perhaps around 85°C. But Maarten de Wit at the Nelson Mandela Metropolitan University in Port Elizabeth, South Africa, now says ocean temperatures at that time were similar to today's.
