3-D Model of Projectile Point (VIDEO)
Caption
A 360-degree video of a three-dimensionally modeled Clovis projectile point from the Smithsonian's National Museum of Natural History research collections. Scientists analyzed and compared three-dimensional models like this one from the Smithsonian and other museum collections to identify how and when early Americans' technology became regionally distinct 12,500 years ago. These regional differences signal cultural diversification and adaptation, suggesting that groups of early Americans may have changed the way they were social interacting at this time.
