WalkerART-2025-148642Walker’s "Homo informatio" offers a compelling and thought-provoking re-examination of our evolutionary past, presenting a deliberate departure from conventional paradigms and challenging the actualist perspective. The "Homo informatio" framework invites us to embrace a more nuanced, dynamic model of human evolution. We commend this bold deviation from received wisdom. It is implausible to conceive of human evolution as a linear, uninterrupted ascent up an intellectual ladder. Rather, the development of human cognition and social structures was likely characterized by irregular progress, iterative experimentation, and the sporadic invention and reinvention of tools, ideas, and practices [1]. These innovations, often emerging from individual actors, only became culturally embedded when recognized by the group as functionally advantageous2025http://zaguan.unizar.es/record/17012610.1016/j.plrev.2025.12.006http://zaguan.unizar.es/record/170126oai:zaguan.unizar.es:170126Physics of Life Reviews 56 (2025), 115-117All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/closedAccess
