005 Clovis Spear Point 22 Jan 2010

Fri, 22 Jan 10

This sharp spearhead helps us understand how humans spread across the globe. By 11,000 BC humans had moved from north-east Asia into the uninhabited wilderness of north America. Within 2,000 years they had populated the whole continent. How did these hunters live, and how is their Asian origin reflected in the creation stories of modern-day Native Americans? Including contributions from Michael Palin and American archaeologist Gary Haynes.
