The structuralist theory of evolution is reconsidered in the light of new discoveries. According to this theory, the evolutionary potentialities are in the genotype (a hierarchically ordered set of interacting elements) and manifest themselves in the course of morphogenesis in association with changes in the environment. It is demonstrated that this theory is in fact the development of a long philosophical tradition, in which Darwin and Neo-Darwinism did not participate. New discoveries in the field of molecular cytogenetics confirm the ideas of evolutionary potentiality and hierarchical genotypic ordering. It is demonstrated that gene regulation can manifest itself in association with instabilities of the morphogenetic field and the attainment of a new equilibrium; this change could be connected with changes in the environment, but has nothing to do with natural selection.
鉴于新的发现，结构主义进化理论被重新审视。根据这一理论，进化潜力存在于基因型（一组相互作用元素的分层有序集合）中，并在形态发生过程中与环境变化相关联地表现出来。事实证明，这一理论实际上是一个悠久哲学传统的发展，达尔文和新达尔文主义并未参与其中。分子细胞遗传学领域的新发现证实了进化潜力和基因型分层排序的观点。事实证明，基因调控可以与形态发生场的不稳定性以及新平衡的达成相关联地表现出来；这种变化可能与环境变化有关，但与自然选择无关。
