He also found that punctuated evolution explained about 22% of such genetic changes, with the remainder unfolding smoothly through time.

他还发现大约22%的遗传变化要通过间断式进化来解释，其余的则通过随时间渐进式进化来解释。

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。

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

In many more cases, a great idea evolved progressively, often through a succession of more modest innovations or improvements, so that while the final product may be overtly better, its evolution was more gradual than punctuated.

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.
