Evolution of adaptive phenotypic traits without positive Darwinian selection.

Heredity - 1 Apr 2012

Hughes A L

Abstract excerpt

Recent evidence suggests the frequent occurrence of a simple non-Darwinian (but non-Lamarckian) model for the evolution of adaptive phenotypic traits, here entitled the plasticity-relaxation-mutation (PRM) mechanism. This mechanism involves ancestral phenotypic plasticity followed by specialization in one alternative environment and thus the permanent expression of one alternative phenotype. Once this...
