Abstract

This paper argues that embryonic development is best understood through the lens of process philosophy rather than traditional substance metaphysics. Drawing on both contemporary developmental biology and process thought, I demonstrate how key phenomena in embryogenesis-including morphogenesis, cellular differentiation, and organismal integration-align naturally with process-philosophical principles. Through critical engagement with major figures in developmental biology and philosophy of biology, including Turing's mathematical theory of morphogenesis and autopoietic approaches to biological organization, I show how persistent difficulties in developmental biology stem from implicit substance-metaphysical assumptions and demonstrate how a process framework better captures the dynamic, relational nature of development. Furthermore, I argue that this perspective provides novel insights into emergence in biological systems while resolving longstanding theoretical difficulties in developmental biology. This theoretical framework has important implications for both biological understanding and experimental practice.
