Abstract

It appears that knappers intentionally produced symmetrical stones. Use of the dorsal pathways in knapping does not preclude shape perception, nor does it obviate use of ventral pathways in other tasks in Homo sapiens 400,000 years ago. Shape perception precedes production in present-day human infants, suggesting that symmetry perception was used by knappers of symmetrical stones.
