The rebirth of rational morphology

This paper examines a new challenge to neo-Darwinism, a movement known as process structuralism. The process structuralist critique of neo-Darwinism holds 1) that there are general laws in biology and that biologists should search for these laws; 2) that there are general forms of morphology and development and that biologists should attempt to uncover these forms; 3) that organisms are unified wholes that cannot be understood without adopting a holistic perspective; and 4) that no special, causal primacy should be given to the genes in development and morphology. This paper places process structuralism in its historical context, examines the philosophical underpinnings of the movement, and discusses some of the evidence used to support its claims.
