It has been commonly accepted that human ancestors managed to tame the power of fire around 350,000 years ago, after Neanderthal tribes migrated from Africa into Europe. It was believed that Neanderthals had been in Europe for 600,000 years prior to harnessing fire. However, in South Africa researchers have found evidence that humans had used fire much earlier than that. Francesco Berna, from the University of Boston, filed a reportabout his team's findings at a North Cape excavation, which uncovered blocks of sediment one million years old that contained traces of burnt plant matter and animal bones. When submitted to an infrared microspectroscopy, the molecular evidence showed that the bones had been heated to over 500 degrees Celsius.
