The punctuated equilibrium model (above) consists of morphological stability followed by episodic bursts of evolutionary change via rapid cladogenesis. It is contrasted (below) to phyletic …

But in 1972, evolutionary scientists Stephen Jay Gould and Niles Eldredge proposed another explanation, which they called "punctuated equilibrium." That is, species are generally stable, …

Punctuated equilibrium is a theory used to justify coding, but time and variation won’t go away. It is a point in Darwin’s favor that the Origin of Species and natural selection both featured time …

With the model of punctuated equilibria, an unbiased distribution of evolutionary tempos can be established by treating stasis as data and by recording the pattern of change for all species in …

Punctuated equilibrium is a theory about how new species evolve that was first advanced by American paleontologists Niles Eldredge and Stephen Jay Gould (1941–2002) in 1972.
