Theory of Cosmic Gene Seeding and Dual Origin of Life

This paper proposes a **dual-origin hypothesis of life** combining cosmic gene seeding and terrestrial indigenous evolution. Breaking through the single framework of both purely terrestrial abiogenesis and traditional panspermia, it holds that life on Earth originated from two parallel paths: the exogenous implantation of cosmic genetic materials and the spontaneous evolution of terrestrial substances. It also discusses the transmission mechanism of interstellar gene carriers and the synergistic relationship between planetary environments and life gestation, providing a new speculative framework and theoretical supplement for the multi-causal research of life origin. 本研究提出宇宙基因播种与地球本土演化并行的生命双重起源假说。突破单一地球内源起源与传统宇宙泛种论的单一框架,认为地球生命存在外源宇宙基因植入、本土物质自发演化两条并行起源路径;探讨星际基因载体传播机制与行星环境生命孕育的协同关系,为生命起源多元成因提供全新思辨模型与理论补充。
