Epigenesis
Epigenesis is the concept that emphasizes development resulting from ongoing bidirectional exchanges between heredity and all levels of the environment.
Epigenesis is the development of organisms such as plants, animals and fungi from an egg, seed, or spore or egg through a series of phases in which unorganized cells differentiate into organs and organs systems. The theory of epigenesis which claimed that structures evolve during development that are not already preformed was created by the German physician C. F. Wolff in 1759.
