Book excerpt: Mesoamerica is one of six major areas of the world where humans independently changed their culture from a nomadic hunter-gatherer lifestyle into settled communities, cities, and civilization. In addition to China (twice), the Indus Valley, the Fertile Crescent of southwest Asia, Egypt, and Peru, Mesoamerica was home to exciting and irreversible changes in human culture called the "Neolithic Revolution." The changes included domestication of plants and animals, leading to agriculture, husbandry, and eventually sedentary village life. These developments set the stage for the growth of cities, social stratification, craft specialization, warfare, writing, mathematics, and astronomy, or what we call the rise of civilization. These changes forever transformed humankind. The Historical Dictionary of Mesoamerica covers the history of Mesoamerica through a chronology, an introductory essay, an extensive bibliography, and over 900 cross-referenced dictionary entries covering the major peoples, places, ideas, and events related to Mesoamerica. This book is an excellent access point for students, researchers, and anyone wanting to know more about Mesoamerica.
