This volume is an outgrowth of a symposium entitled 'Hunter-Gatherers and their Neighbors in Asia, Africa, and South America,' organized by Kazunobu Ikeya and chaired by Robert K. Hitchcock. The symposium was held as part of the Conference on Hunting and Gathering Societies (CHAGS) 10 at the University of Liverpool in Liverpool, United Kingdom from 25-28 June, 2013. All of the papers have been revised substantially and updated since the time they were originally presented.
