Fixation and Selection (II) — Reproductive Law Forecloses Replication / 固与选(二)——繁殖律封闭复制

This series (Fixation and Selection) investigates the same phenomenon within each round of the Life Cycle Table: the fourth step (fixation) forecloses the first step (selection). This essay unfolds Round 2 (5DD–8DD): how reproductive law (8DD) forecloses replication (5DD). Round 2's foreclosure is biological — imperceptible but with observable consequences: species extinction, evolutionary dead ends, loss of genetic diversity. The threefold mechanism — genetic path dependence, confirmation bias in natural selection, biological energy conservation — forms a positive feedback loop. The only structural exit is Bridge 2 (8DD→9DD): reproductive law's remainder (offspring vary but the organism does not choose) gives rise to choice. 本系列(固与选)追问生命周期表每一轮内部的同一个现象:第四步(固)封闭第一步(选)。本篇展开第二轮(5DD-8DD):繁殖律(8DD)如何封闭复制(5DD)。第二轮的封闭是生物的——不可感知,但后果可观察:物种灭绝、进化死胡同、基因多样性丧失。三重机制——遗传路径依赖、自然选择的确认偏误、生物能量节约——形成正反馈循环。唯一的结构性出口是小桥2(8DD→9DD):繁殖律的余项(后代有差异但生命体自己不选)涌现出选择。 Keywords: Fixation and Selection, reproductive law, replication, evolution, path dependence, natural selection, genetics, Self-as-an-End License: Creative Commons Attribution 4.0 International (CC BY 4.0) Resource type: Preprint Language: Chinese / English (bilingual) Related identifiers: Is part of: DOI 10.5281/zenodo.18808585 (Self-as-an-End Theory Series) Is continued by: DOI 10.5281/zenodo.18859363 (Fixation and Selection I) References: DOI 10.5281/zenodo.18779382 (Philosophy as Subject-Activity) References: DOI 10.5281/zenodo.18818107 (Life Cycle Table Upper Volume) References: DOI 10.5281/zenodo.18818149 (Life Cycle Table Middle Volume) References: DOI 10.5281/zenodo.18818177 (Life Cycle Table Lower Volume) References: DOI 10.5281/zenodo.18829136 (AI Consciousness Impossibility Theorem)
