The terms used by naturalists, of affinity, relationship, community of type, paternity, morphology, adaptive characters, rudimentary and aborted organs, etc., will cease to be metaphorical and will have a plain signification.

博物学家使用的亲和力、 关系、 共同类型、 亲子关系、形态学、 适应性特征、 发育不全和堕落的器官等术语将不再是隐喻性的， 而将具有明确的含义。
