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。

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。

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）”。

Mr Gould's opponents referred to punctuated-equilibrium theory as evolution by jerks.

Those who worked with what was alive in an infinity of yesterdays complained that even though they had no good explanation of why punctuated-equilibrium theory worked, you couldn't argue with the evidence in the rocks, maths or no maths.

Though punctuated-equilibrium theory as originally conceived has made few converts, the role of accidents in evolution is more widely appreciated, as asteroid collisions and nearby supernovae are recognised as hazards that can wipe out whole groups of organisms arbitrarily.
