Tooby and Cosmides proposed some rules about functional analysis:①functional analysis should be expressed in adaptationist terms,②a set of phenotypic properties is not an adaptation if it is transient, varying from individual to individual,③adaptations should be distinguished from their expression (which may vary from context to context),④a set of phenotypic properties is not an adaptation if it was absent in the environment of evolutionary adaptedness,⑤a set of phenotypic properties is not an adaptation if it did not solve an adaptive problem in the environment of evolutionary adaptedness.

图比和考斯米戴丝提出了功能分析的原则：①功能分析应该用适应的术语来表达；②一系列表现型的特点如果是暂时的，在不同的个体身上发生变化，它并非是一种适应；③适应应该与它们的表现（在不同的情景中可能发生变化）区分开；④一系列表现型的特点如果在进化适应性环境中不存在，则不是一种适应；⑤一系列表现型的特点如果不能解决进化适应性环境中的一种适应性的问题，也不是一种适应。

目前对物种濒危机理的研究大都局限在形态学角度，很少有生理生态学角度的研究，对于荷叶铁线蕨生长条件的研究也多停留在定性分析上，很少有定量分析其最适生长环境，本实验采用形态学与生理生态学结合的思想，并将采用构件理论的研究方法，拟进一步探讨长期以来各自独立发展的植物分类学、形态学、生理学、生态学等学科之间的内在联系，以期能在一个新的高度上探讨濒危物种的生存、适应对策和进化机制。
