作为理解非遗传系统中进化前组织的一步，我们开发了一个模型来研究简单信息处理实体（自动机）相互作用的群体中原始自组织网络的出现和动态。我们的模拟表明，动态稳定的强连接网络的相互产生的通信信道出现在特定的环境条件下。我们把这些不同的组织稳定状态称为信息小生境。在每种情况下，我们测量的信息内容的香农熵，并确定适应景观，鲁棒性和过渡路径的信息壁龛受到间歇性的环境扰动下的非进化条件。通过确定产生每个生态位所需的信息，我们表明，生态位转换是唯一允许的，如果伴随着一个平等的或增加的信息生产水平，产生内部或通过环境扰动，作为一个外源性的人口多样化。总的来说，我们的模拟显示了基本信息处理器的原始自生成网络是如何形成和竞争的，以及在什么条件下它们会随着时间的推移而持续存在或灭绝。这些发现可能与理解无生命系统（如化学通信的原始细胞）如何在当代进化和遗传机制开始之前启动向生命物质的过渡有关。
As a step towards understanding pre-evolutionary organization in non-genetic systems, we develop a model to investigate the emergence and dynamics of proto-autopoietic networks in an interacting population of simple information processing entities (automata). Our simulations indicate that dynamically stable strongly connected networks of mutually producing communication channels emerge under specific environmental conditions. We refer to these distinct organizational steady states as information niches. In each case, we measure the information content by the Shannon entropy, and determine the fitness landscape, robustness and transition pathways for information niches subjected to intermittent environmental perturbations under non-evolutionary conditions. By determining the information required to generate each niche, we show that niche transitions are only allowed if accompanied by an equal or increased level of information production that arises internally or via environmental perturbations that serve as an exogenous source of population diversification. Overall, our simulations show how proto-autopoietic networks of basic information processors form and compete, and under what conditions they persist over time or go extinct. These findings may be relevant to understanding how inanimate systems such as chemically communicating protocells can initiate the transition to living matter prior to the onset of contemporary evolutionary and genetic mechanisms.
