Scientists analyzed three-dimensional models of Clovis projectile points from Smithsonian and other museum collections to examine how patterns and marks made in crafting these tools began to vary regionally 12,500 years ago. These regional differences signal cultural diversification and adaptation, suggesting that groups of early hunter-gatherer Americans may have changed the way they were social interacting at this time. This figure shows one analysis used to study shapes left behind from their production on either side of the projectile points.
