  • Parks fly as stone meets stone, and shards of rock ricochet off the furniture around one. Each strike makes him flinch, but Bruce Bradley is the picture of cool concentration as he chips away at his axe head. It is, after all, a skill he has been honing since before he can remember. When his family moved to Arizona, he developed his talents by copying the Native American arrowheads scattered across the desert. Decades later, Bradley makes stone tools spanning the breadth of human history. His workshop at the University of Exeter in UK, is full of this handiwork, Piles of rocks line the walls, and to one side a deerskin with a dark stain hangs on a wooden frame. Here, Robson discusses how humans became the smartest creatures on Earth and how the story of their ancestors' mental leaps can be found in stones.
