The Requirements of a Selection Theory "'[T]he abstract general requirements on any selection theory are (1) a source of diversification leading to variants, (2) a means for effective encounter with or sampling of an independent environment that is not initially categorized in any absolute or predetermined fashion, and (3) a means of differential amplification over some period of time of those variants in a population that have greater adaptive value.'
