An '''adaptive system''' is a set of interacting or interdependent entities, real or abstract, forming an integrated whole that together are able to respond to environmental changes or changes in the interacting parts, in a way analogous to either continuous physiological [[homeostasis]] or evolutionary [[adaptation]] in [[biology]]. [[Feedback loops]] represent a key feature of adaptive systems, such as [[ecosystems]] and individual [[organisms]]; or in the human world, [[communities]], [[organizations]], and [[families]].

In an adaptive system, a parameter changes slowly and has no preferred value. In a self-adjusting system though, the parameter value “depends on the history of the system dynamics”.

在自适应系统中，参数变化缓慢，没有优先值。然而，在一个自调整系统中，参数值“取决于系统动力学的历史”。自调节系统最重要的特性之一是它能“适应混沌的边缘”或避免混沌的能力。实际上，如果一个领导者走向混乱的边缘而不走得更远，那么他就可以在没有灾难的情况下自发地行动。2009年3 / 4月的一篇文章进一步解释了自我调节系统的使用和现实意义。物理学家已经证明，对混沌边缘的适应几乎发生在所有具有反馈的系统中。

在一个生命系统中，各种类型的适应性是如何相互作用的？拓扑实践，这个术语源于它的发明者 Danko nikoli，是对回答这个问题的适应机制层次的一个参考。这种适应性层次结构形成了一种自我调节系统，其中整个生物体或细胞的自创生是通过各组分之间的异体生成相互作用而发生的。这是可能的，因为组件被组织成一个极端层次结构: 一个组件的自适应操作导致另一个组件的创建。该理论提出，生命系统展示了一个由四个这样的适应性极化操作组成的等级体系:
''evolution'' (i) → ''gene expression'' (ii) → ''non gene-involving homeostatic mechanisms (anapoiesis)'' (iii) → ''final cell function'' (iv)
evolution (i) → gene expression (ii) → non gene-involving homeostatic mechanisms (anapoiesis) (iii) → final cell function (iv)
进化(i) ; 基因表达(ii) ; 非基因参与的稳态机制(anapoiesis) ; (iii) ; 最终细胞功能(iv)
As the hierarchy evolves towards higher levels of organization, the speed of adaptation increases. Evolution is the slowest; the final cell function is the fastest. Ultimately, practopoiesis challenges current neuroscience doctrine by asserting that mental operations primarily occur at the homeostatic, anapoietic level (iii) — i.e., that minds and thought emerge from fast homeostatic mechanisms poietically controlling the cell function. This contrasts the widespread belief that thinking is synonymous with neural activity (i.e., with the 'final cell function' at level iv).

This contrasts the widespread belief that thinking is synonymous with neural activity (i.e., with the 'final cell function' at level iv).
随着等级制度向更高层次的组织发展，适应的速度也在加快。进化是最慢的，最后的细胞功能是最快的。最终，实践拓扑学挑战当前的神经科学学说，认为心理活动主要发生在稳态，非生物水平(iii)——也就是说，头脑和思想从快速的稳态机制中产生，从而控制了细胞功能。这与人们普遍认为的思考是神经活动的同义词(也就是说，与第四级的“最终细胞功能”)形成了鲜明对比。
Each slower level contains knowledge that is more general than the faster level; for example, genes contain more general knowledge than anapoietic mechanisms, which in turn contain more general knowledge than cell functions. This hierarchy of knowledge enables the anapoietic level to directly activate concepts, which are the most fundamental ingredient for the emergence of the mind.

每一个较慢的层次包含的知识比较快的层次包含的知识更普遍; 例如，基因包含的一般知识比无生殖机制多，而无生殖机制又比细胞功能包含更多的一般知识。这种知识的层次结构使得无生命层次能够直接激活概念，而这些概念是头脑出现的最基本要素。

This contrasts the widespread belief that thinking is synonymous with neural activity (i.e., with the 'final cell function' at level iv).
随着等级制度向更高层次的组织发展，适应的速度也在加快。进化是最慢的，最后的细胞功能是最快的。最终，实践拓扑学挑战当前的神经科学学说，认为心理活动主要发生在稳态，非生物水平(iii)——也就是说，头脑和思想从快速的稳态机制中产生，从而控制了细胞功能。这与人们普遍认为的思考是神经活动的同义词(也就是说，与第四级的“最终细胞功能”)形成了鲜明对比。
Each slower level contains knowledge that is more general than the faster level; for example, genes contain more general knowledge than anapoietic mechanisms, which in turn contain more general knowledge than cell functions. This hierarchy of knowledge enables the anapoietic level to directly activate concepts, which are the most fundamental ingredient for the emergence of the mind.

每一个较慢的层次包含的知识比较快的层次包含的知识更普遍; 例如，基因包含的一般知识比无生殖机制多，而无生殖机制又比细胞功能包含更多的一般知识。这种知识的层次结构使得无生命层次能够直接激活概念，而这些概念是头脑出现的最基本要素。
