This book examines the first human colonization of Asia and particularly the tropical environments of Southeast Asia during the Upper Pleistocene. In studying the unique character of the Asian archaeological record, it reassesses long-accepted propositions about the development of human 'modernity.' Ryan J. Rabett reveals an evolutionary relationship between colonization, the challenges encountered during this process - especially in relation to climatic and environmental change - and the forms of behaviour that emerged. This book argues that human modernity is not something achieved in the remote past in one part of the world, but rather is a diverse, flexible, responsive and ongoing process of adaptation.
