This heuristic was also applied to the theory of punctuated equilibrium proposed by Niles Eldredge and Gould.

His theory of peripatric speciation ( a more precise form of allopatric speciation which he advanced ), based on his work on birds, is still considered a leading mode of speciation, and was the theoretical underpinning for the theory of punctuated equilibrium, proposed by Niles Eldredge and Stephen Jay Gould.

Phacopid trilobite Eldredgeops rana crassituberculata, the genus is named after Niles Eldredge

Niles Eldredge ’ s study of the Phacops trilobite genus supported the hypothesis that modifications to the arrangement of the trilobite ’ s eye lenses proceeded by fits and starts over millions of years during the Devonian.

This and other data led Stephen Jay Gould and Niles Eldredge to publish the seminal paper on punctuated equilibrium in 1971.

It is a term coined by Stephen Jay Gould and Niles Eldredge to contrast with their model of punctuated equilibrium, which is gradualist itself, but argues that most evolution is marked by long periods of evolutionary stability ( called stasis ), which is punctuated by rare instances of branching evolution.

In 1972, paleontologists Niles Eldredge and Stephen Jay Gould published a landmark paper developing this theory and called it punctuated equilibria.

Although some of the basic workings of the theory were proposed and identified by Mayr in 1954, historians of science generally recognize the 1972 paper by Niles Eldredge and Stephen Jay Gould as the foundational document of the new paleobiological research program.

A year before their 1972 Eldredge and Gould paper, Niles Eldredge published a paper in the journal Evolution which suggested that gradual evolution was seldom seen in the fossil record and argued that Ernst Mayr's standard mechanism of allopatric speciation might suggest a possible resolution.

I coined the term punctuated equilibrium and wrote most of our 1972 paper, but Niles is the proper first author in our pairing of Eldredge and Gould.

Gould's most significant contribution to science was the theory of punctuated equilibrium, which he developed with Niles Eldredge in 1972.

Early in his career, Gould and Niles Eldredge developed the theory of punctuated equilibrium, in which evolutionary change occurs relatively rapidly, alternating with longer periods of relative evolutionary stability.

While some evolutionary biologists claim that speciation events have remained relatively constant over time, some palaeontologists such as Niles Eldredge and Stephen Jay Gould have argued that species usually remain unchanged over long stretches of time, and that speciation occurs only over relatively brief intervals, a view known as punctuated equilibrium.

Extinction of a species ( or replacement by a daughter species ) plays a key role in the punctuated equilibrium hypothesis of Stephen Jay Gould and Niles Eldredge.

* 1972 — Stephen Jay Gould and Niles Eldredge proposed an idea they call " punctuated equilibrium ", which states that the fossil record is an accurate depiction of the pace of evolution, with long periods of " stasis " ( little change ) punctuated by brief periods of rapid change and species formation ( within a lineage ).

Kim Sterelny ( 2007 ) cites this rapid natural selection as illustrating an important point about periods of relative stasis in the punctuated equilibrium hypothesis of Niles Eldredge and Stephen Jay Gould: " In claiming that species typically undergo no further evolutionary change once speciation is complete, they are not claiming that there is no change at all between one generation and the next.

Averre, Niles and Gary briefly continued on with former RoadMaster vocalist Stephen ' Mac ' McNally as " The Game " after the Knack's initial break up.

* 1972 — Niles Eldredge and Stephen Jay Gould propose punctuated equilibrium, claiming that the evolutionary history of most species involves long intervals of stasis between relatively short periods of rapid change.

The theory of punctuated equilibrium developed by Stephen Jay Gould and Niles Eldredge and first presented in 1972 is often mistakenly drawn into the discussion of transitional fossils.

Although these approaches were not always welcomed ( at least initially ) by specialists in the subjects examined, SOC has nevertheless become established as a strong candidate for explaining a number of natural phenomena, including: earthquakes ( which, long before SOC was discovered, were known as a source of scale-invariant behaviour such as the Gutenberg-Richter law describing the statistical distribution of earthquake sizes, and the Omori law describing the frequency of aftershocks ); solar flares ; fluctuations in economic systems such as financial markets ( references to SOC are common in econophysics ); landscape formation ; forest fires ; landslides ; epidemics ; and biological evolution ( where SOC has been invoked, for example, as the dynamical mechanism behind the theory of " punctuated equilibria " put forward by Niles Eldredge and Stephen Jay Gould ).

Niles Eldredge ( born August 25, 1943 ) is an American paleontologist, who, along with Stephen Jay Gould, proposed the theory of punctuated equilibrium in 1972.

In his book The Blind Watchmaker, Dawkins argues against the idea that Charles Darwin himself was a constant-rate gradualist, as suggested by Niles Eldredge and Stephen Jay Gould.

Niles was also the original announcer for Let's Make a Deal during that show's first season in 1963 and 1964 ; he was later replaced by Jay Stewart.

According to Gould " the ideas came mostly from Niles, with yours truly acting as a sounding board and eventual scribe.

In 1972, the notion of gradualism in evolution was challenged by a theory of " punctuated equilibrium " put forward by Gould and Niles Eldredge, proposing evolutionary changes could occur in relatively rapid spurts, when selective pressures were heightened, punctuating long periods of morphological stability, as well-adapted organisms coped successfully in their respective environments.

Deeds and G. Rentschler persuaded the board of Niles Bement Pond that their Pratt & Whitney Machine Tool subsidiary of Hartford, Connecticut, should provide the funding and location to build a new aircraft engine being developed by Rentschler, George J. Mead, and colleagues, all formerly of Wright Aeronautical.

Due to his Vietnam experience, Sam Niles developed severe claustrophobia, which becomes a key factor in the MacArthur Park shooting.

She must now take medicine developed by Doom Patrol leader Niles Caulder to prevent her heart from going into cardiac arrest, due to her tiny form.

" I Wonder as I Wander " was developed by Niles out of the mere three lines he was able to extract from a revivalist preacher ’ s daughter, " a tousled, unwashed blond, and very lovely ".

He has stated that he believes justice should be the same for everyone when he refused to help Niles take care of a legal problem for Maris ; he has, nevertheless used his position as an ex-policeman for preferential treatment on occasion, such as when he flashed his badge to a border guard in order to alleviate his suspicions.

Niles danced to the same song in his underwear with a feather duster.
