Junco beaks在大流行性校园关闭期间被延长,然后被逆转,显示出人类驱动的变化的迅速演变。 Junco beaks lengthened during pandemic campus closures, then reversed, showing rapid evolution from human-driven changes.

在这次大流行病期间,加州大学洛杉矶分校的黑眼美洲狮鸣鸟生长了更长的嘴,这可能是由于校园活动减少时食物供应情况发生变化所致。 During the pandemic, dark-eyed junco songbirds at UCLA developed longer beaks, likely due to changes in food availability when campus activity dropped. 研究人员认为,这种转变在学生返回后发生逆转,可能反映环境变化推动的快速演变。 Researchers suggest this shift, reversing after students returned, may reflect rapid evolution driven by environmental changes. 这些结果公布在PNAS中,显示野生动物能够迅速适应人为干扰,对实时进化过程有洞察力。 The findings, published in PNAS, show wildlife can adapt quickly to human-driven disruptions, offering insight into real-time evolutionary processes.
