Tools of the Trade presents a collection of academic papers from the 2005 Chacmool archaeological conference which includes a wide range of contributions from international archaeologists, senior professors & students alike. Each chapter focuses on the discussion & application of unique & innovative 'tools' for archaeological analysis & interpretation, including micro- & macro-botanical analysis, experimental study, off-site survey, lithic use-wear, ceramic petrography, DNA analysis, chaîne opératoire, space syntax, & Geographic Information Systems. As a collective volume, Tools of the Trade also covers an impressive diversity of geographic regions & time periods, such as Precolumbian Mesoamerica, Plio-Pleistocene Africa, prehistoric & historic North America, & ancient Polynesia. Finally, this volume provides a somewhat introspective look at the origins of tool use, technological development, & the means by which we have become the only species to ask the questions: What does it mean to be us & how can we find out?
