analyze stone projectile points crafted by North America's earliest

show evidence of a shift toward more experimentation in their production
beginning about 12,500 years ago, following hundreds of years of
consistent stone-tool production created using uniform techniques. The
findings provide clues into changes in social interactions during a time
when people are thought to have been spreading into new parts of North
America and adapting to different environments, beginning a period of
cultural diversification.
