论文摘要
生物体准确感知环境和相应反应的能力对于进化成功至关重要。但是，确切的感觉能力如何影响健身是一个积极研究的话题，而在感知不可靠的环境线索和有机体可以安装反应时，尚未探索任何时间段的时间延迟的必要性。考虑到人口增长模型中表型响应的这种延迟，我们发现在某些环境条件下可能存在关键误差概率：具有任何误差概率的有机体小于临界值可以达到与具有完美感应系统的有机体相同的长期增长率。我们还观察到感觉信息的进化值与鲁棒性的进化值，这是由表型分布放松到稳态的速率介导的。临界误差概率的存在可能会带来几种重要的进化后果，主要是在非零关键误差概率上运行的感觉系统可能在进化上是最佳的。
The ability of organisms to accurately sense their environment and respond accordingly is critical for evolutionary success. However, exactly how the sensory ability influences fitness is a topic of active research, while the necessity of a time delay between when unreliable environmental cues are sensed and when organisms can mount a response has yet to be explored at any length. Accounting for this delay in phenotype response in models of population growth, we find that a critical error probability can exist under certain environmental conditions: an organism with a sensory system with any error probability less than the critical value can achieve the same long-term growth rate as an organism with a perfect sensing system. We also observe a trade off between the evolutionary value of sensory information and robustness to error, mediated by the rate at which the phenotype distribution relaxes to steady-state. The existence of the critical error probability could have several important evolutionary consequences, primarily that sensory systems operating at the non-zero critical error probability may be evolutionarily optimal.
