Proponents of punctuated equilibrium included such scientists asWilliam Bateson, a strong opponent of Darwin's views,who argued that species do not evolve gradually. A number of explanations have been given for this phenomenon observed in the fossil record. Of course, the fossil record is incomplete, leading to the problem of the missing links.

Theyre also a common assignment for college essays since they show the instructor how well you grasp both subjects. Thus the key difference between Gradualism and Punctuated equilibrium is the period of time it takes to assume changes. This model of the timing of evolution is called gradualism.

For example, while, Australopithecus afarensis, is the precursor of modern humans, there are no fossils showing a gradual change in the cranial capacity or body size of the Australopithecus. Punctuated equilibrium, by contrast, is based on the idea that since you cannot see changes in a species, there must be very long periods when no changes occur. This evidence supports the punctuated equilibrium theory. in a similar manner. Intermediate forms may be found in regions where fossils are abundant and well-preserved. The study of kingfishers in Papua New Guinea showed the deep impact of reproductive isolation on speciation. 4. Interbreeding populations appear static. Punctuated equilibrium is a theory that states that evolution occurs primarily through short bursts of intense speciation, followed by lengthy periods of stasis or equilibrium. Also, when dating the fossils, scientists saw that in some species change was very slow, but in others, it must have occurred rapidly to be able to produce such change over such a short amount of time.
