363. 两性寿命差异的奥秘
from 知为谁 · host 知为谁
这段文字节选自一篇题为《女性比男性长寿。科学家可能终于知道原因了。》的文章，该文章探讨了哺乳动物中雌性寿命通常比雄性更长的原因。研究人员分析了圈养动物的数据，发现除了遗传因素外，性选择——即为获得交配优势而产生的特定性状——是决定两性平均寿命差异的重要因素。文章指出，雌性哺乳动物拥有两条X染色体的遗传优势可能提供了对有害突变的保护，但在非人类物种中，竞争激烈的交配压力会耗尽资源，从而缩短雄性的寿命。这项研究表明，雌性寿命更长的趋势可能根植于人类的进化历史中，且在圈养环境下这种寿命优势更为明显。内容来源：https://www.popularmechanics.com/science/a68805403/women-live-longer-than-men/
