Merlin Donald is the cognitive scientist who solved, or came close to solving, the oldest puzzle in the study of human uniqueness: why the brain of a theoretical physicist and the brain of a Paleolithic hunter are biologically identical while the physicist can calculate the mass of the Higgs boson and the hunter could not count beyond the fingers of both hands.
