Document Summary
Rethinking epigenesis and evolution in light of developmental science lickliter. Notion of genes as primary cause of developmental and evolutional processes. And evolution critiquing instruction for building organisma reside in their genes that fenes are the exclusive vehicles by which instructions are transmitted from one generation to next and that there is no feedback from env, to genes. Split of development and evolution however synthesis of devptal processes brings evolutionary change. Development as describe as being programmed in the genes and evolutionarily significant changes in in programmed genes. Process of development involves progression from simpler to more complex org. Development is creating something more from something less increasing complexity across indiv. dvpt. Epigenesis (aristotle) idea that embryos gradually develop by the successive formation of new parts. Viewed as emergence of new characters and traits in organized embryo from a relatively unstructured egg.
