1620年代,“选择的行为,选择的行动,被选中或被选择的事实”,源自拉丁语 selectionem(格 selectio)“选择,选定,挑选”,是 seligere 的动名词,意为“选择,挑选,选出; 分离,挑选”(参见 select(形容词))。
“被选择的事物,一些被选择的事物,特定的选择”一词始于1805年。生物学上的“将要生存和繁殖的生命形式与不会生存和繁殖的生命形式分离”的意义始于1837年,指人类对植物和动物进行系统育种的 methodical selection,因此达尔文在1857年将其扩展为指自然和时间的非人为代理的结果 natural selection。法语 sélection 是19世纪从英语借来的。
