The analysis of the inherent context-dependence of genetic information suggests that there are evolutionary mechanisms which are independent of the processes of environmental adaptation and yet are able to push prebiotic matter towards functional complexity. In this regard, the extension of information space, by random prolongation of the primary structure of biological macromolecules, must have played a decisive role in the origin of life. On the one hand, the extension of information space is tantamount to an increase in the syntactic complexity of potential information carriers, which in turn is a prerequisite for the nucleation and evolution of semantic information. On the other hand, the increase in the dimensionality of information space expands the number of possible pathways of evolutionary optimisation and thereby improves the possible choices that can be made by progressive evolution. Alongside the optimisation of evolutionary optimisation itself, there are principles of evolutionary dynamics that direct the formation of functional order in prebiotic matter. Since these principles are constitutive for the proto-semantics of genetic information, they may be regarded as the elements of the semantic code of evolution.
对遗传信息内在上下文依赖性的分析表明，存在一些进化机制，它们独立于环境适应过程，但仍能将前生物物质推向功能复杂性。在这方面，通过随机延长生物大分子的一级结构来扩展信息空间，必定在生命起源中起了决定性作用。一方面，信息空间的扩展等同于潜在信息载体句法复杂性的增加，而这反过来又是语义信息成核与进化的先决条件。另一方面，信息空间维度的增加扩大了进化优化可能路径的数量，从而改善了渐进进化可做出的可能选择。除了进化优化本身的优化之外，还有进化动力学原理指导前生物物质中功能秩序的形成。由于这些原理是遗传信息原语义的构成要素，它们可被视为进化语义代码的元素。
