Abstract

This paper presents an alternative conceptual foundation for biological evolution. First the causal and statistical perspectives on evolutionary fitness are analyzed, finding them to implicitly depend on each other, and hence cannot be individually fundamental. It is argued that this is an instance of a relativistic perspective over evolutionary phenomena. New accounts of fitness, the struggle for life, and Natural Selection are developed under this interpretation. This biological relativism is unique in that it draws from General Relativity in physics, unlike previous theories that drew upon statistical mechanics or Newtonian dynamics. A mathematical law of evolutionary change, as well as new theoretical biological concepts to underpin it, are likewise developed. The law and theory are then applied to give examples of how both cornerstones and edge cases can be understood using these new methods. Using General Relativistic Biology provides fresh insight into evolution, all while preserving the core, canonical scientific research program.
