摘要

可进化性的概念出现在20世纪90年代初,并很快成为进化生物学不同研究流的时髦标签。在进化定量遗传学中,进化能力被定义为种群对方向选择作出反应的能力。这与其他领域的不同之处在于,它将可进化性视为群体的特性,而不是生物体或谱系的特性,它侧重于量化和短期预测,而不是宏观进化。虽然“可进化性”一词对定量遗传学来说是新的,但许多相关的想法和研究问题从生物计量学开始就与该领域有关。然而,最近关于可进化性的研究不仅仅是对老问题的重新贴标签。新的可进化性操作措施为理解对快速环境变化的适应、评估遗传约束以及将微观和宏观进化联系起来提供了可能性。

Evolvability: A Quantitative-Genetics Perspective
The concept of evolvability emerged in the early 1990s and soon became fashionable as a label for different streams of research in evolutionary biology. In evolutionary quantitative genetics, evolvability is defined as the ability of a population to respond to directional selection. This differs from other fields by treating evolvability as a property of populations rather than organisms or lineages and in being focused on quantification and short-term prediction rather than on macroevolution. While the term evolvability is new to quantitative genetics, many of the associated ideas and research questions have been with the field from its inception as biometry. Recent research on evolvability is more than a relabeling of old questions, however. New operational measures of evolvability have opened possibilities for understanding adaptation to rapid environmental change, assessing genetic constraints, and linking micro- and macroevolution.

期刊介绍: The Annual Review of Ecology, Evolution, and Systematics is a scholarly publication that has been in circulation since 1970. It focuses on important advancements in the areas of ecology, evolutionary biology, and systematics, with relevance to all forms of life on Earth. The journal features essay reviews that encompass various topics such as phylogeny, speciation, molecular evolution, behavior, evolutionary physiology, population dynamics, ecosystem processes, and applications in invasion biology, conservation, and environmental management. Recently, the current volume of the journal transitioned from a subscription-based model to open access through the Annual Reviews' Subscribe to Open program. Consequently, all articles published in the current volume are now available under a CC BY license.
