'Evolvability' - the ability to undergo adaptive evolution - is a key concept for understanding and predicting the response of biological systems to environmental change. Evolvability has various facets and is applied in many ways, easily leading to misunderstandings among researchers. To clarify matters, we first categorize the mechanisms and organismal features underlying evolvability into determinants providing variation, determinants shaping the effect of variation on fitness, and determinants shaping the selection process. Second, we stress the importance of timescale when studying evolvability. Third, we distinguish between evolvability determinants with a broad and a narrow scope. Finally, we highlight two contrasting perspectives on evolvability: general evolvability and specific evolvability. We hope that this framework facilitates communication and guides future research.
“可进化性”——即经历适应性进化的能力——是理解和预测生物系统对环境变化反应的关键概念。可进化性具有多个方面，并以多种方式应用，这很容易导致研究人员之间产生误解。为了厘清这些问题，我们首先将构成可进化性基础的机制和生物体特征分为提供变异的决定因素、塑造变异对适应性影响的决定因素以及塑造选择过程的决定因素。其次，我们强调研究可进化性时时间尺度的重要性。第三，我们区分了具有广泛和狭窄范围的可进化性决定因素。最后，我们突出了关于可进化性的两种截然不同的观点：一般可进化性和特定可进化性。我们希望这个框架能够促进交流并指导未来的研究。
