Abstract
Global geographical patterns of repressive, painful, traumatic, and violent patrist behaviors and social institutions, which thwart materal‐infant and male‐female bonds, were correlated and developed through a systematic analysis of anthropological data on 1170 subsistence‐level cultures. When the behavior data were mapped, the hyperarid desert belt encompassing North Africa, the Near East, and Central Asia, which I call Saharasia, was found to possess the greatest areal extent of the most extreme patrist behaviors and social institutions on Earth. Regions farthest removed from Saharasia, in Oceania and the New World, were found to possess the most extreme matrist behaviors, which support and protect maternal‐infant and male‐female bonds. A systematic review of archaeological and historical materials suggests that patrism first developed in Saharasia after c.4000 BCE, the time of a major ecological transition from relatively wet grassland‐forest conditions to arid desert conditions. Settlement and migration patterns of patrist peoples were traced, from their earliest homelands in Saharasia, to explain the later appearance of patrism in regions outside of Saharasia. Prior to the onset of dry conditions in Saharasia, evidence for matrism is widespread, but evidence for patrism is generally nonexistent. It is argued that matrism constitutes the earliest, original, and innate form of human behavior and social organization, while patrism, perpetuated by trauma‐inducing social institutions, first developed among Homo Sapiens in Saharasia, under the pressures of severe desertification, famine, and forced migrations.
