摘要
We argue for multiple forms of life realized through multiple different historical pathways. From this perspective, there have been multiple origins of life on Earth—life is not a universal homology. By broadening the class of originations, we significantly expand the data set for searching for life. Through a 計算 analogy, the origin of life describes both the origin of hardware (physical substrate) and software (evolved function). Like all 資訊-processing systems, adaptive systems possess a nested hierarchy of levels, a level of function optimization (e.g., fitness maximization), a level of constraints (e.g., energy requirements), and a level of materials (e.g., DNA or RNA 基因組 and cells). The functions essential to life are realized by different substrates with different efficiencies. The fu
