Fire-making materials at 400,000-year-old site are the oldest evidence of humans making fire

Fragments of iron pyrite, a rock that can be used with flint to make sparks, were found by a 400,000-year-old hearth in eastern Britain.

Archaeologists in Britain say they've found the earliest evidence of humans making fires anywhere in the world. The discovery moves our understanding of when humans started making fire back by 350,000 years.
