大约在1300年,"从原始或祖先中的家谱提取",源自法语单词 descente "血统,后代,世系",该词是由 descendre "下降"(参见 descend)构成的,类似于法语名词,如 attente 来自 attendre "期待", vente "销售" 来自 vendre "出售", pente "斜坡" 来自 pendre "悬挂"(从拉丁语词源来看,英语单词应该是 *descence)。
从14世纪晚期开始,"下降的动作"(在); "从高处到低处的行为"以任何方式的含义开始出现; "下坡"的含义则出现在1590年代。从大约1600年开始,它被用来表示"突然的入侵或攻击"。在达尔文的1859年的生物学意义中,"进化"一词开始出现,尽管在1630年代就有一些用法基本上暗示了同样的事情。
