Stone Tools in Human Evolution : Behavioral Differences among Technological Primates

This book explains in simple, straightforward terms what stone tools are, how and why they vary, and what that variability means for human evolution. It is a book about stone tools written for students and for non-archaeologists by an expert at making, using, and analyzing stone tools.

In Stone Tools in Human Evolution, John J. Shea argues that over the last three million years hominins'' technological strategies shifted from occasional tool use, much like that seen among living non-human primates, to a uniquely human pattern of obligatory tool use. Examining how the lithic archaeological record changed over the course of human evolution, he compares tool use by living humans and non-human primates and predicts how the archaeological stone tool evidence should have changed as distinctively human behaviors evolved. Those behaviors include using cutting tools, logistical mobility (carrying things), language and symbolic artifacts, geographic dispersal and diaspora, and residential sedentism (living in the same place for prolonged periods). Shea then tests those predictions by analyzing the archaeological lithic record from 6,500 years ago to 3.5 million years ago.
