What are the opposite words for preformation theory?

Preformation theory refers to the idea that an organism develops from a pre-existing miniature version of itself. Some antonyms for preformation theory include epigenesis, gradualism, and developmental plasticity. Epigenesis is the belief that an organism develops from simple to complex structures through a series of developmental stages. Gradualism posits that changes in organisms occur over an extended period of time through a series of small, incremental changes. Developmental plasticity is the concept that an organism is not predetermined by its genes and that the environment can have a significant impact on its development. These antonyms challenge the deterministic aspect of preformation theory and suggest a more flexible and evolution-driven approach to development.
