Adaptive Plasticity and Resilience Congruity of Dental and Mandibular Morphology of Asian Homo Erectus and Impact on Hominin Craniodental Continuity

The discoveries of Asian Homo erectus - Homo erectus erectus (Java Man) and Homo erectus pekinensis (Peking Man) in the late 19th and early 20th centuries revolutionized paleoanthropology by providing the first definitive evidence of early human dispersal out of Africa. Asian Homo Erectus was regarded as a highly adaptable species that was able to survive, and to some extent, flourish for over a million years in varied Pleistocene climactic environments from the dense tropical ecology of Southeast Asia to the temperate ecology of East Asia. It is the forensic examination of Dental and mandibular morphology of Asian Homo erectus that provides critical insights into the dietary adaptation, ecological flexibility and paleobiology of this widespread hominin. This study synthesizes current evidence from dental metrics, enamel thickness, occlusal wear patterns, and mandibular biomechanics to reconstruct feeding ecology across different Pleistocene Asian environments. Our findings indicate that while both Java Man and Peking Man exhibit definitive Homo erectus dental and mandibular morphology, their evolutionary relationship to later Asian Hominin populations is impactful. We identify critical gaps in the fossil record and provide targeted research directions to further ascertain the role of Asian Homo erectus in the Hominin craniodental morphology continuity. The paper provides a detailed analysis of their dental, cranial and mandibular resilience congruity; a remarkable quality of adaptive plasticity that was considerably responsible for the survival of the taxa for over a million years.
