China Shandong Evolution Model Chapter 1: Reconstructing the Coordinate System of Human Evolution

The “Out of Africa” theory has dominated paleoanthropology for nearly half a century, resting on the premise that the earliest anatomically modern human fossils appear in Africa, therefore modern humans originated there and subsequently replaced archaic populations across Eurasia. This monograph identifies a fundamental logical leap in this reasoning: “earliest appearance” does not equal “evolutionary completion”. Drawing on parallels from evolutionary biology (theropod dinosaurs to avian flight) and technological history (Mesopotamian wheels to Fordist mass production), I argue that the site of initial anatomical emergence need not be the site where cognitive/behavioral modernity was forged. While affirming Africa’s foundational contribution as the provider of the anatomical “hardware” of modern humans, this monograph challenges the dogma of Africa as the sole origin of the human mind and the unidirectional dispersal narrative built upon it. A global genealogy of critique—from 19th-century challenges to the “single cradle” premise, through the 1987 same-journal rebuttal of “Mitochondrial Eve”, to 21st-century methodological, fossil, archaeological, and molecular critiques—demonstrates that the absolute validity of the African single cradle has been eroding for decades. I propose a fundamental reorientation in environmental thinking: the key question is not “grassland versus forest” but the mode of environmental forcing. Africa’s low-latitude dry-wet oscillation demands physiological endurance but not cognitive restructuring. In contrast, the East Asian mid-latitudes (30°–45°N) exhibit a unique bipolar oscillation—extreme winter–summer reversal forcing repeated switching between Arctic and tropical survival logics within a single generation. This contradictory pressure, I argue, is the true trigger of behavioral modernity, demanding long-term planning, resource storage, flexible social networks, and abstract temporal prediction—capacities whose co-occurrence defines behavioral modernity. This monograph proposes the “Mid-Latitude Oscillation Model” , reconstructing human evolution across seven dimensions: geology, climate, hominoid paleontology, the Mid-Pleistocene Transition, the Mengxihe site (86–68 ka), the LSED framework, and a reverse migration model. We assign functional roles without value hierarchy: Africa as Infrastructure Provider, East Asia as Core Algorithm Iteration Zone, South Asia as Unidirectional Router/Firewall, and Europe as Stress-Testing Ground and Methodological Library. The history of human evolution is not a unidirectional arrow from a single cradle but a complex tapestry of multi-regional, multi-directional, reticulated interweaving. Out of Africa is merely the opening chapter of the somatic lineage; the formation of cognitive algorithms likely involved global multi-regional network coupling. The African dispersal narrative records only the opening chapter of human somatic evolution; the complete narrative of human cognitive becoming requires the integration of East Asian cognitive forging and global reticulated interweaving.
