An autocatalytic set is a collection of entities, each of which can be created catalytically by other entities within the set, such that as a whole, the set is able to catalyze its own production.  In this way the set as a whole is said to be autocatalytic.  Autocatalytic sets were originally and most concretely defined in terms of molecular entities, but have more recently been metaphorically extended to the study of systems in sociology and economics.

自动催化装置是一组实体的集合,每一个实体都可以由装置内的其他实体催化地创造出来,这样,作为一个整体,该装置能够催化自己的生产。这样,集合作为一个整体被称为是自催化的。自动催化集最初和最具体的定义是分子实体,但最近隐喻地扩展到社会学和经济学系统的研究。

自催化集合是一组实体的集合,每一个实体都可以由集合内的其他实体催化而创造出来。这样一来,作为一个整体,该集合能够催化其自身的生成。以这种方式,该集合作为一个整体被称为是自催化的。自催化集合最初是用分子实体来定义的,这种定义也是最具体的,但最近被隐喻地扩展到社会学和经济学系统的研究。
    
Autocatalytic sets also have the ability to replicate themselves if they are split apart into two physically separated spaces. Computer models illustrate that split autocatalytic sets will reproduce all of the reactions of the original set in each half, much like cellular [[mitosis]]. In effect, using the principles of autocatalysis, a small metabolism can replicate itself with very little high level organization. This property is why autocatalysis is a contender as the foundational mechanism for complex evolution.

自催化集也有能力复制自己,如果他们分裂成两个物理上分开的空间。计算机模型表明,分裂的自动催化装置将在每一半重现原始装置的所有反应,很像细胞有丝分裂。实际上,利用自动催化的原理,一个小的新陈代谢可以自我复制,很少有高层次的组织。这就是为什么自动催化作为复杂进化的基本机制是一个竞争者。

如果自催化集合被分裂成物理上分离的两个空间,它们仍有复制自身的能力。计算机模型表明,分裂来的每一半自催化集合都将重新自生成出初始集合中的所有反应,就像细胞有丝分裂一样。实际上,利用自催化的原理,一个小的代谢系统可以在几乎没有高水平组织的情况下自复制。这种性质解释了为什么自催化能作为复杂进化的基本机制。
    
Prior to [[James D. Watson|Watson]] and [[Francis Crick|Crick]], biologists considered autocatalytic sets the way [[metabolism]] functions in principle, i.e. one [[protein]] helps to synthesize another protein and so on. After the discovery of the [[double helix]], the [[central dogma of molecular biology]] was formulated, which is that [[DNA]] is transcribed to [[RNA]] which is translated to protein. The molecular structure of DNA and RNA, as well as the metabolism that maintains their reproduction, are believed to be too complex to have arisen spontaneously in one step from a soup of chemistry.

在沃森与克里克之前,生物学家认为自我催化设定了新陈代谢功能的原则,即。一种蛋白质帮助合成另一种蛋白质等等。在发现双螺旋:发现DNA结构的故事之后,中心法则被制定出来,即 DNA 转录成 RNA,再转化成蛋白质。DNA 和 RNA 的分子结构,以及维持它们繁殖的新陈代谢,被认为过于复杂,不可能在化学混合物的一个步骤中自发产生。

Several models of the [[origin of life]] are based on the notion that life may have arisen through the development of an initial molecular autocatalytic set which evolved over time.  Most of these models which have emerged from the studies of [[complex system]]s predict that life arose not from a molecule with any particular trait (such as self-replicating [[RNA World|RNA]]) but from an autocatalytic set.

生命起源的几个模型都是基于这样一个概念,即生命可能是通过一个随着时间演化的初始分子自催化集的发展而产生的。从复杂系统研究中产生的大多数模型都预测,生命并非起源于具有任何特定特征的分子(例如自我复制的 RNA) ,而是起源于一个自我催化的集合。第一个经验性的支持来自 Lincoln 和 Joyce,他们获得了自催化装置,其中“两个[ RNA ]酶催化对方的合成,从总共四个组成底物。”此外,一个由这些自复制因子群体开始的进化过程产生了一个由重组复制因子控制的群体。
