 Phenomena such as these may be characterized as being “Lamarckian” in flavor, even though they operate according to traditional Darwinian theory, since they provide room for instructive or induced processes in evolution. The epigenetic, behavioral, and symbolic dimensions in evolution discussed by Jablonka and Lamb produce induced variation which may affect evolution through processes of assimilation as well as through their hereditary affects. In this way various inheritance systems other than the genetic can indirectly affect the evolution of genetic traits.
