"If through a mutation a character appears that is neither advantageous nor disadvantageous, but indifferent, the chance that it may become established in the race is extremely small, although by good luck such a thing may occur rarely. It makes no difference whether the character in question is a dominant or a recessive one, the chance of its becoming established is exactly the same. If through a mutation a character appears that has an injurious effect, however slight this may be, it has practically no chance of becoming established. If through a mutation a character appears that has a beneficial influence on the individual, the chance that the individual will survive is increased, not only for itself, but for all of its descendants that come to inherit this character. It is this increase in the number of individuals possessing a particular character, that might have an influence on the course of evolution."-Thomas Hunt Morgan 1916
进化论Mutationism 说每一个大的生物群体里，都存在着少数与众不同的群体;它们会受到主流排斥及打压，要靠比其它优秀才能存活下来。久而久之它们的优点就会蔓延出去，成为主流，这就形成了一个突变的进化周期！反之，如果这少数群体是不优秀，甚至有害的，那么它将永远被主流打压甚至消失！
