<p>This work is an abridged Greek translation of selected book chapters and articles about James DeMeo&#39;s work and discovery on 'Saharasia'.&nbsp; The full Saharasia book is presently available only in the original 465-page English edition, describing a series of new discoveries on the origins of human violence and warfare, and associated-correlated cultural characteristics.&nbsp; It is a warning to the world about the violent cultural make-up of the peoples who today live across the large Saharasian Desert Belt, and how that region converted from a green to a hyperarid desert landscape.&nbsp; Lessons are found for both ancient and modern cultures on the dangers of severe drought, desertification and climate change in shaping social and cultural institutions, and human behavior.&nbsp; This summary work is in the Greek language.</p>
