Summary – gradualism vs punctuated equilibrium 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 gradualism and punctuated equilibrium are two such theories put forward to explain the evolution of a species. Generation after generation can come and go before any changes in a species are observed there is some debate in the scientific community as to how quickly evolution occurs the two generally accepted ideas for rates of evolution are called gradualism and punctuated equilibrium.

Proponents of gradualism say that the geologic time scale helps show how species have changed over the different eras since life began on earth punctuated equilibrium 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.
Biology chapter 10 study play what important concepts about earth did hutton and lyell agree upon they agreed upon the idea that change occurred gradually over time and that the geological processes that shaped earth were uniform throughout time how are gradualism and catastrophism different. Behavioral= different behavior keep the population separate and therefor is different temporal= mating during different seasons leads to inability to reproduce geographical= when 2 organisms are separated by some geographic object and eventually evolve into organisms so different that they cannot reproduce.
Explain the difference between gradualism and punctuated equilibrium gradualism - slow steady change in species punctuated equilibrium - slow evolution punctuated by short events of rapid evolution what is the differnce between divergent and convergent evolution. In darwin’s studies, he found phyletic gradualism and punctuated equilibrium are dissimilar and similar in the ways which the evolution of a species can occur forms of species can evolve by only one or the other, or occasionally both. Gradualism is the concept where it is believed that the large changes are actually the culmination of very small changes that build up over timepunctuated equilibrium states that changes in species take place over a relatively short amount of time “punctuating” the long periods of equilibrium.

Both gradualism and punctuated equilibrium describe the rates of speciation for gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for punctuated equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change [1.
Punctuated equilibrium (also called punctuated equilibria) is a theory in evolutionary biology which proposes that once species appear in the fossil record the population will become stable, showing little evolutionary change for most of its geological history.

Gradualism versus punctuationism although modern evolutionists are thought to be divided on the issues surrounding evolutionary theory, a close look at the evidence suggests that both the gradualist school of thought and the punctuationist school of thought share many characteristics in common.
Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur a species can evolve by only one of these, or by both scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly by gradualism gradualism is selection and variation that happens more gradually. Gradualism and punctuated equilibrium gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur a species can evolve by only one of these, or by both scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly by gradualism. Phyletic gradualism and punctuated equilibrium science 101 ip # 2 olivia altamirano february 24, 2014 there are numerous mis-conceptions concerning punctuated equilibrium in the year of 1972, stephen jay gould and niles eldredge introduced the idea of punctuated equilibrium, a far-reaching notion in the time.
