This fascinating book continues the story begun in the bestselling & critically acclaimed book The Mind in the Cave. Drawing on the latest research & recent discoveries, the authors skilfully link material on human consciousness, imagery & belief systems to propose provocative new theories about the causes of an ancient revolution in cosmology, the origins of social complexity & even the drive behind the domestication of plants & animals. In doing so they create a fascinating neurological bridge to the mysterious thought-lives of the past & reveal the essence of a momentous period in human history.
