选择信号的全基因组扫描已经成为群体基因组变异数据集分析的常规部分,并在最近的人类进化过程中产生了令人信服的选择证据。这篇文章重点介绍了方法论上的创新,这些创新使得在最近的时间尺度上,甚至在当代人类群体中,能够检测到选择。通过利用大规模的基因组和表型数据集,这些新方法使用不同的策略来揭示基因型、表型和适应性之间的联系。本文概述了每种策略的基本原理和主要发现,讨论了解释中的挑战,并描述了提高对人类种群中正在进行的选择的检测和理解的机会。在最近的人类进化中,有什么证据表明选择是持续的?本文着眼于新方法和技术如何帮助揭示基因型、表型和种群水平上的适应性之间的联系。
Genome-wide scans for signals of selection have become a routine part of the analysis of population genomic variation datasets and have resulted in compelling evidence of selection during recent human evolution. This Essay spotlights methodological innovations that have enabled the detection of selection over very recent timescales, even in contemporary human populations. By harnessing large-scale genomic and phenotypic datasets, these new methods use different strategies to uncover connections between genotype, phenotype, and fitness. This Essay outlines the rationale and key findings of each strategy, discusses challenges in interpretation, and describes opportunities to improve detection and understanding of ongoing selection in human populations. What is the evidence for ongoing selection in recent human evolution? This Essay looks at how new methods and techniques are helping to uncover connections between genotype, phenotype, and fitness at a population level.
