自然界中的颜色介导了物种之间和物种内部的许多相互作用，1长期以来，人为影响对野生动物的颜色进化产生了重大影响。2一个未被探索的领域是商业捕捞，它可以对动物的各种特征施加强大的选择压力，有时甚至比自然选择或其他人类活动更大。4被人类利用的植物的自然种群也可能受到收获的强大压力，然而人类引起的进化变化的潜力却令人惊讶地很少受到关注。我们发现，一种用于传统中药的草本植物（川贝母）的叶色在种群之间存在差异，其中叶色与其当地背景最为接近。背景匹配的程度与收获压力的估计，与植物更神秘，在大量收集的人口。在人类搜索实验中，参与者找到植物所需的时间受到目标隐藏的影响很大。这些结果表明，人类通过商业收获推动了该物种种群伪装的进化，以一种意想不到的戏剧性方式改变了野生植物的表型。
Color in nature mediates numerous among and within species interactions,1and anthropogenic impacts have long had major influences on the color evolution of wild animals.2An under-explored area is commercial harvesting, which in animals can exert a strong selection pressure on various traits, sometimes greater even than natural selection or other human activities.3,4Natural populations of plants that are used by humans have likely also suffered strong pressure from harvesting, yet the potential for evolutionary change induced by humans has received surprisingly little attention.5Here, we show that the leaf coloration of a herb used in traditional Chinese medicine (Fritillaria delavayi) varies among populations, with leaves matching their local backgrounds most closely. The degree of background matching correlates with estimates of harvest pressure, with plants being more cryptic in heavily collected populations. In a human search experiment, the time it took participants to find plants was greatly influenced by target concealment. These results point to humans as driving the evolution of camouflage in populations of this species through commercial harvesting, changing the phenotype of wild plants in an unexpected and dramatic way.
