The objective of this volume is to showcase the contemporary state of research on recognizing and evaluating the performance of stone age weapons from a variety of viewpoints, including investigating their cognitive and evolutionary significance. New archaeological finds and experimental studies have helped to bring this subject back to the forefront of human origins research. In the last few years, investigations have expanded beyond examining the tools themselves to include studies of damage caused by projectile weapons on animal and hominin bones and skeletal asymmetries in ancient hominin populations. Only recently has there been a growing interest in controlled and replicative experiments. Through this book readers will be updated in the state of knowledge through a multidisciplinary scientific reconstruction of prehistoric weapon use and its implications. Contributions from expert authors are organized into three themed parts: recognizing weapon use (experimental and archaeological studies of impact traces), performance of weapon systems (factors influencing penetration depth etc.), and behavioral and evolutionary ramifications (cognitive and ecological effects of using different weapons).
This new edition introduces more problem-solving strategies and new conceptual and challenge problems. Also, each Chapter Review has been enhanced with Learning Goals to reinforce the mastery of concepts for students.
This laboratory manual contains 42 experiments for the standard sequence of topics in general, organic, and biological chemistry.
The book guides students through basic chemistry problem solving with engaging visuals and a focus on developing the math skills necessary to be successful in the course.
