摘要
Background: Recent work has revealed that many 生物 systems keep functioning in the face of 突變s and therefore can be considered 遺傳ally robust. However, several issues related to robustness remain poorly understood, such as its implications for evolvability (the ability to produce adaptive 演化ary innovations). Results: Here, we use the Avida digital 演化 platform to explore the effects of 遺傳 robustness on evolvability. First, we obtained digital organisms with varying levels of robustness by evolving them under combinations of 突變 rates and 族群 sizes previously shown to select for different levels of robustness. Then, we assessed the ability of these organisms to adapt to novel environments in a variety of experimental conditions. The data consistently support that, for simple environments, 遺傳 rob
