This book combines the latest studies of Near Eastern Neolithic lithics by leading international archaeologists to develop their analytical potential and advance our understanding of the world oldest farming societies of the Near East in human history.This volume presents the proceedings of the 9th International Conference of the Pre-Pottery Neolithic Chipped and Ground Stone Industries of the Near East, hosted at the University of Tokyo, Japan, from November 12 to 16, 2019 (PPN9-Tokyo).A unique point of the volume, while referring to the origins and development as in the proceedings of the previous conferences, is a greater emphasis on regional perspectives to evaluate the Near Eastern Neolithic. The current research indicates that the earliest farming societies of the Near East developed in interaction with neighbouring hunter-gatherer societies, that either coexisted with them for long periods or soon assimilated to the Near Eastern farmers. Understanding these contrasting processes would shed new light on identifying the Neolithisation practices of the “core” regions in the Near East itself. A similar attempt was made at the PPN2-Warsaw in 1995, but the present volume provides the most up-to-date discoveries and perspectives after a quarter century.The 39 papers in this volume include contributions on the Iranian Zagros, the Caucasus, and Central Asia, a region whose Neolithic archaeological records are far less well understood but that we believe will enrich our understanding of the first farming societies of the Near East.
