1·The evolution of North American horse, which was once presented as a classic textbook example of gradual evolution, is now providing equally compelling evidence for punctuated equilibrium.

北美马的进化，曾经被作为一个经典的渐进演化的教科书案例，现在为点断平衡说提供了同样令人信服的证据。

2·The punctuated equilibrium hypothesis attempts to explain a curious feature of the fossil record—one that has been familiar to paleontologists for more than a century but has usually been ignored.

断点平衡论试着去解释化石记录的一个古怪的特点——在超过一个世纪的时间里，这一特点已经为古生物学者所熟悉，但一直被忽视。

3·This motif matches the general pattern of evolution found in earthly fossils, a pattern known in the evolutionary trade as punctuated equilibrium, or punk eek for short.

这个模式与从早期化石里发现的进化的常见模式相契合，该模式在进化论业界里叫做间断平衡（punctuated equilibrium）［7］，或简称为“蹦移（punk eek）”。

4·The Internet, which has become the backbone fore-commerce and e-business, has disrupted a wide range of industries -- more a punctuated equilibrium than a disruption.

已经成为电子商务支柱的Internet， 就已使大范围的行业产生剧变--更多的是打断的平衡而不仅仅是一次剧变。
