达尔文认为:“如果我们看每一种生物都是一种不知名的生物的后代,那么它的亲本及所有过渡物种应该被新的更完美的新种消灭了。制造新种的同时就消灭了旧种。”(Hence, if we look at each species as descended from some other unknown form, both the parent and all the transitional varieties will generally have been exterminated by the very process of formation and perfection of the new form.)¹¹⁴
20世纪中叶,美国加州大学伯克利分校著名动物学家、遗传学家理查德‧戈德施米特教授(Prof. Dr. Richard Goldschmidt, 1878—1958)这样评论:“没有人通过微突变的积累成功地生产出一个新物种。达尔文进化论的自然选择理论从来没有任何证据可证明,但却被普遍接受。”“通过微进化不可能形成任何新物种。”“微观进化 (物种内的变化) 的事实不足以理解宏观进化(从一个物种到另一个物种的理论上的变化)。”(It is good to keep in mind … that nobody has ever succeeded in producing even one new species by the accumulation of micromutations. Darwin’s theory of natural selection has never had any proof, yet it has been universally accepted. It’s impossible by micro-mutation to form any new species. The facts of microevolution [change within the species] do not suffice for an understanding of macroevolution [theorized change from one species to another].)¹¹⁵
