In a previous article (Goswami, 1997), it was suggested that an application of quantum measurement theory under the auspices of a monistic idealist ontology (that consciousness is the ground of being) can solve many difficult problems of neo-Darwinism, e.g., alternating rapid creativity and homeostasis observed in evolution and the directionality, origin, and nature of life. In this article, we propose an epigenetic quantum mechanism to explain the connection of developmental processes and evolution, as has been evidenced in such controversial phenomena as directed mutation and phenocopies.
