Both punctuated equilibrium and phyletic gradualism are not mutually incompatible, and examples of each have been documented in different lineages.
32.
This theory, known as punctuated equilibrium, was part of Gould's work that brought a forsaken paleontological perspective to the evolutionary mainstream.
33.
Change occurs by the gradual operation of natural forces over time, perhaps slowly, perhaps more quickly ( see punctuated equilibrium ).
34.
Some argued that his theories, like punctuated equilibrium, were so malleable and difficult to pin down that they were essentially untestable.
35.
This and other data led Stephen Jay Gould and Niles Eldredge to publish their seminal paper on punctuated equilibrium in 1971.
36.
Gould's most significant contribution to evolutionary biology was the theory of punctuated equilibrium, which he developed with Niles Eldredge in 1972.
37.
His fight not just for his own theories of punctuated equilibrium, but for equilibrium in science itself was Gould's gift to us.
38.
The idea that evolutionary change happens in " spurts " rather than just gradually at a constant pace is known as punctuated equilibrium.
39.
The " edge of chaos " is a borderline region that lies between complete anarchy or randomness and a state of punctuated equilibrium.
40.
The theory of punctuated equilibrium developed by Stephen Jay Gould and Niles Eldredge is often mistakenly drawn into the discussion of transitional fossils.
