"Ancient archaeological sites across the Northern Hemisphere have been littered with a mystery. Where there were hominins, there too could often be found roughly rounded spheres of stone. Some have been dated back to over 2 million years ago, with marks suggesting that the balls had been deliberately shaped.

New research has discovered a plausible purpose for these strange tools: Our ancestors could have been using them to smash open bones - to get to the nutritious marrow inside."
