This camp of scientists believes that change happens very rapidly with long periods of stability and no change in between. Several species of salamander rapidly radiate through an island chain to become new species. Thats when compare-and-contrast essays function at their best. These include the effect of gene flow, assertions that the morphology of a species is under homeostatic pressure, and koinophilia or the rejection of mates with unusual attributes. The species changes very rapidly over a few generations, then settles down again to a period of little change. <> The species will then maintain a period of stability, called stasis, for a long period of time. Until recently, one species continued to survive on the island. Punctuated equilibrium vs. phyletic gradualism | Request PDF - ResearchGate . Gradualism vs punctuated equilibrium | Theory of evolution Punctuated equilibrium states that changes in species take place over a relatively short amount of time punctuating the long periods of equilibrium. Of course, the fossil record is incomplete, leading to the problem of the missing links. Evolution is a complex process that takes place over time and is subjected to many controversies due to the theories expressed by different groups of scientists.
