摘要
The 演化ary origins of 遺傳 robustness are still under debate: it may arise as a consequence of requirements imposed by varying environmental conditions, due to intrinsic factors such as metabolic requirements, or directly due to an adaptive selection in favor of genes that allow a 物種 to endure 遺傳 perturbations. Stratifying the individual effects of each origin requires one to study the pertaining 演化ary forces across many 物種 under diverse conditions. Here we conduct the first large-scale 計算 study charting the level of robustness of metabolic 網絡s of hundreds of 細菌l 物種 across many simulated growth environments. We provide evidence that variations among 物種 in their level of robustness reflect ecological 適應s. We decouple metabolic robustness into two components and quantify the extents of each: th
