Encyclopedia of Quaternary Science, Third Edition, Six Volume Set brings together the multidisciplinary expertise needed to understand the history of humans, life, environmental, and climate change to understand what we may expect over the coming decades. Since publication of the previous edition, our understanding of many topics has been revolutionized by new discoveries and new techniques. The development of ancient DNA studies, for example, has revolutionized our thinking about the origins, dispersal, and population dynamics of our ancestors. Every new aDNA analysis from ancient human remains causes the story to become more complex. We are the sole survivors of the genus Homo, yet we harbor genetic fragments from other closely related but long-extinct lineages. The Quaternary is uniquely situated as a laboratory in which to study the shaping of the modern world, including biotic responses to large-scale environmental change. This new edition of this book is the most comprehensive account of state-of-the-art research in this field.
