This paper critically examines the conventional, often linear, understanding of human evolution encapsulated in the singular concept of Homo. It argues for a paradigm shift towards a "polycentric evolution," recognizing multiple, geographically and culturally diverse origins and pathways in hominin development. This polycentric view challenges the notion of a monolithic human essence, thereby necessitating a rethinking of the "humanities" as inherently "plural." By synthesizing insights from evolutionary anthropology, critical theory, and posthumanist thought, the paper deconstructs the universalizing tendencies within traditional humanistic discourse. It posits that acknowledging the complex, multi-branched nature of human origins—involving varied forms of cognition, sociality, and environmental interaction across different hominin species—provides a more robust and inclusive foundation for understanding what it means to be human. Ultimately, this framework advocates for humanities that embrace a multiplicity of epistemologies, experiences, and forms of existence, moving beyond a Western-centric or singular definition of humanity to encompass a truly global and diverse tapestry of human and human-like life.
