Contrasting Explanatory Foci and Gene Concepts in Two Approaches to an Evolutionary Process
Paul E. Griffiths
A large body of literature exists on the so-called “Baldwin effect”, a controversial process by which an acquired trait supposedly evolves into an innate trait. C. H. Waddington's concept of “genetic assimilation” is significantly different from other ideas about how this might occur. From Waddington's perspective, evolutionary transitions between “innate” and “acquired” are to be expected because those categories have little meaning in terms of developmental genetics. Waddington's approach necessitates a different conception of the gene from that found in other literature on the Baldwin effect. Keywords:Waddington,
