Gaia会掷骰子吗？：非达尔文选择机制的简单模型
Does Gaia Play Dice? : Simple Models of non-Darwinian Selection
AI总结：
本文提出基于掷骰子的简单模型，解析探讨解释行星宜居性的非达尔文选择机制，发现幸存选择和序列选择仅源于抽样效应，而带记忆的序列选择则能体现系统随时间改善的统计趋势。
摘要：
本文引入了一些基于掷骰子的简单模型，以探讨解释行星宜居性的机制。其核心思想是在一个解析可处理的环境中研究这些选择机制，将其影响与其他细节隔离开来，这些细节在更现实的模型中可能会混淆或掩盖它们的作用。我们发现，尽管我们关注的可观测量——骰子显示的面值——在所有模型中都随时间“改善”，但对于其中两个更主流的观点，即“幸存选择”和“序列选择”，这实际上归因于抽样效应。序列选择的一个修正版本，即“带记忆的序列选择”，则意味着系统随时间改善的统计趋势。我们讨论了其影响及其与“栖居悖论”和“Gaian瓶颈”概念的关系。
英文摘要：
In this paper we introduce some simple models, based on rolling dice, to explore mechanisms proposed to explain planetary habitability. The idea is to study these selection mechanisms in an analytically tractable setting, isolating their consequences from other details which can confound or obscure their effect in more realistic models. We find that while the observable of interest, the face value shown on the die, `improves' over time in all models, for two of the more popular ideas, Selection by Survival and Sequential Selection, this is down to sampling effects. A modified version of Sequential Selection, Sequential Selection with Memory, implies a statistical tendency for systems to improve over time. We discuss the implications of this and its relationship to the ideas of the `Inhabitance Paradox' and the `Gaian bottleneck'.
