Natural selection successfully explains how organisms accumulate adaptive change despite that traits acquired over a lifetime are eliminated at the end of each generation. However, in some domains that exhibit cumulative, adaptive change—e.g. cultural evolution, and earliest life—acquired traits are retained; these domains do not face the problem that Darwin’s theory was designed to solve. Lack of transmission of acquired traits occurs when germ cells are protected from environmental change, due to a self-assembly code used in two distinct ways: (i) actively interpreted during development to generate a soma, and (ii) passively copied without interpretation during reproduction to generate germ cells. Early life and cultural evolution appear not to involve a self-assembly code used in these two ways. We suggest that cumulative, adaptive change in these domains is due to a lower-fidelity evolutionary process, and model it using reflexively autocatalytic and foodset-generated networks. We refer to this more primitive evolutionary process as self–other reorganization (SOR) because it involves internal self-organizing and self-maintaining processes within entities, as well as interaction between entities. SOR encompasses learning but in general operates across groups. We discuss the relationship between SOR and Lamarckism, and illustrate a special case of SOR without variation.

没有变异和选择的进化过程

自然选择成功地解释了生物体如何积累适应性变化,尽管一生中获得的特征在每一代结束时都被消除了。然而,在一些表现出累积性、适应性变化的领域——例如文化进化和最早的生命——后天获得的特征被保留了;这些领域没有面临达尔文理论旨在解决的问题。当生殖细胞受到保护免受环境变化影响时,缺乏后天性状的传递会发生,这是由于自组装代码以两种不同的方式使用:(i)在发育过程中主动解释以产生体细胞,以及(ii)在没有解释的情况下被动复制繁殖产生生殖细胞。早期生活和文化进化似乎不涉及以这两种方式使用的自组装代码。我们建议累积,这些领域的适应性变化是由于较低保真度的进化过程,并使用反射性自催化和食物集生成的网络对其进行建模。我们将这种更原始的进化过程称为自我-他者重组(SOR),因为它涉及实体内部的内部自组织和自我维护过程,以及实体之间的相互作用。SOR 包括学习,但通常跨小组运作。我们讨论了 SOR 和拉马克主义之间的关系,并说明了 SOR 没有变化的一个特殊情况。我们将这种更原始的进化过程称为自我-他者重组(SOR),因为它涉及实体内部的内部自组织和自我维护过程,以及实体之间的相互作用。SOR 包括学习,但通常跨小组运作。我们讨论了 SOR 和拉马克主义之间的关系,并说明了 SOR 没有变化的一个特殊情况。我们将这种更原始的进化过程称为自我-他者重组(SOR),因为它涉及实体内部的内部自组织和自我维护过程,以及实体之间的相互作用。SOR 包括学习,但通常跨小组运作。我们讨论了 SOR 和拉马克主义之间的关系,并说明了 SOR 没有变化的一个特殊情况。
