加利福尼亚州的红花猴子花在2012-2015年大干旱期间逐渐形成干旱耐受性,遗传变异有利于恢复。 Scarlet monkeyflowers in California evolved drought tolerance during the 2012–2015 megadrought, with genetic variation enabling recovery.

2026年3月12日公布的一项开拓性研究提供了野生植物群中第一个“进化救援”的真实证据,表明加利福尼亚的红雀猴子花在2012-2015年大干旱期间迅速适应。 A groundbreaking study published on March 12, 2026, provides the first real-world evidence of "evolutionary rescue" in wild plant populations, showing that scarlet monkeyflowers in California adapted rapidly during the 2012–2015 megadrought. 研究人员利用55个人口组的基因组数据发现,与干旱容忍有关的遗传特征——如改善节水和光合作用效率——使一些人口得以恢复,干旱前的基因变异预测了生存能力。 Using genomic data from 55 populations, researchers found that genetic traits linked to drought tolerance—such as improved water conservation and photosynthesis efficiency—enabled some populations to recover, with pre-drought genetic variation predicting survival. 由康奈尔大学的Julia Anstett和不列颠哥伦比亚大学的Amy Angert领导的研究结果表明,进化可以帮助某些物种抵御极端气候事件,尽管长期气候变化可能超过适应速度,特别是对慢产物种而言。 The findings, led by Cornell University’s Julia Anstett and University of British Columbia’s Amy Angert, suggest evolution can help some species withstand extreme climate events, though long-term climate change may outpace adaptation, especially for slow-reproducing species.
