The interdisciplinarity between the biological and human sciences is here to serve a daring objective: to decipher, by means of a logical chain, the explanatory factors of human trajectories and imbalances between societies and nations. To do this, The World's Construction Mechanism is based on an unprecedented analysis of the dynamics of the human species, combining the contributions of anthropology, archeology, biology, climatology, economics, geography, history and sociology. This book analyzes the roots of societal disharmony and presents ways of realizing a clear-sighted human project that is in step with the general interest of humanity.
