Evolutionary biologists have long been aware that the effects of genes can reach beyond the boundary of the individual, that is, the phenotypic effects of genes can alter the environment. Yet, we rarely apply a quantitative genetics approach to understand the causes and consequences of genetic variation in the ways that individuals choose and manipulate their environments, particularly in wild populations. Here, I aim to stimulate research in this area by reviewing empirical examples of such processes from the psychology literature. Indeed, psychology researchers have been actively investigating genetic variation in the environments that individuals experience-a phenomenon termed "gene-environment correlation" (rGE)-since the 1970s. rGE emerges from genetic variation in individuals' behavior and personality traits, which in turn affects the environments that they experience. I highlight concepts and examples from this literature, emphasizing the relevance to quantitative geneticists working on wild, nonhuman organisms. I point out fruitful areas of crossover between these disciplines, including how quantitative geneticists can test ideas about rGE in wild populations.

人类的基因-环境相关性:定量遗传学心理学的教训

进化生物学家早就意识到基因的影响可以超越个体的边界,即基因的表型效应可以改变环境。然而,我们很少应用定量遗传学方法来了解个体选择和操纵环境的方式的遗传变异的原因和后果,特别是在野生种群中。在这里,我的目标是通过回顾心理学文献中此类过程的经验实例来刺激该领域的研究。事实上,自 1970 年代以来,心理学研究人员一直在积极研究个体经历的环境中的遗传变异——这种现象被称为“基因-环境相关性”(rGE)。rGE 源于个体行为和性格特征的遗传变异,这反过来又会影响他们所经历的环境。我强调了这些文献中的概念和例子,强调了与研究野生、非人类生物的数量遗传学家的相关性。我指出了这些学科之间富有成效的交叉领域,包括数量遗传学家如何在野生种群中测试关于 rGE 的想法。
