643. 冰河世纪狼腹中的披毛犀基因密码
from 知为谁 · host 知为谁
科学家们最近成功通过分析一只冻土带狼崽胃部留存的披毛犀肉块，完成了这种冰河时代巨兽的全基因组测序。研究表明，尽管披毛犀在约1.4万年前迅速灭绝，但其种群在消失前几百年依然保持着良好的遗传多样性，并未出现近亲繁殖的迹象。这一发现挑战了物种在灭绝前会经历长期衰退的传统观点，暗示其灭绝可能源于气候骤暖引发的突发性环境剧变。通过这种前所未有的古基因组学手段，研究人员能够更深入地理解气候变化对生物多样性的致命威胁。这一成果不仅揭示了史前生物的终结，也为当今应对人为气候变化导致的物种危机提供了警示。内容来源：https://arstechnica.com/science/2026/01/scientists-sequence-a-woolly-rhino-genome-from-a-14400-year-old-wolfs-stomach/
