在人口对快速环境变化的反应中,非基因遗传是一个潜在重要但人们知之甚少的因素。越来越多的证据表明,非基因遗传影响所有生物体的多种性状,并且可以允许环境引起的表型变化(“后天性状”)以及自发产生和高度可变的变异的传播。我们在包含非遗传传播机制的扩大遗传模型的假设下回顾了适应不断变化的环境的模型,并调查了相关的经验例子。理论表明,非基因遗传可以增加表型和遗传变化的速度,并且在某些情况下,可以改变变化的方向。经验证据表明,多种表型——从适应性到病理性的连续体——可以通过非遗传方式传播。因此,非基因遗传的存在使我们对环境变化的进化反应的理解变得复杂。我们概述了一项研究计划,其中包括测试一系列环境因素的跨代影响的实验研究,然后对此类影响的人口水平后果进行理论和实证研究。
Nongenetic inheritance is a potentially important but poorly understood factor in population responses to rapid environmental change. Accumulating evidence indicates that nongenetic inheritance influences a diverse array of traits in all organisms and can allow for the transmission of environmentally induced phenotypic changes (‘acquired traits’), as well as spontaneously arising and highly mutable variants. We review models of adaptation to changing environments under the assumption of a broadened model of inheritance that incorporates nongenetic mechanisms of transmission, and survey relevant empirical examples. Theory suggests that nongenetic inheritance can increase the rate of both phenotypic and genetic change and, in some cases, alter the direction of change. Empirical evidence shows that a diversity of phenotypes – spanning a continuum from adaptive to pathological – can be transmitted nongenetically. The presence of nongenetic inheritance therefore complicates our understanding of evolutionary responses to environmental change. We outline a research program encompassing experimental studies that test for transgenerational effects of a range of environmental factors, followed by theoretical and empirical studies on the population-level consequences of such effects.
