The theory of punctuated equilibrium. Developed by Niles Eldridge and Stephen Jay Gould.
The punctuated equilibrium model of evolution suggests that species remain relatively stable for long periods of time (stasis), with abrupt changes (punctuation) leading to the emergence of new species over short periods of time. This model contrasts with the gradual change proposed by the more traditional gradualism model.
The punctuated equilibrium model of evolution suggests that evolution occurs in rapid bursts of change separated by long periods of stability. This model emphasizes the idea that species evolve quickly in response to environmental changes, leading to abrupt shifts in their characteristics over relatively short periods of time.
This pattern fits the model of punctuated equilibrium in evolution. It suggests that species experience periods of little to no change followed by rapid bursts of evolutionary change that result in new species formation. This is in contrast to gradualism, which posits a slow and constant rate of evolution over time.
A model of evolution showing slow change is gradualism. It proposes that evolution occurs slowly and steadily over time, with species gradually diverging from common ancestors through small, incremental changes. This contrasts with punctuated equilibrium, which suggests that evolution occurs in relatively rapid bursts of change separated by long periods of stability.
The term you're looking for is 'punctuated equilibrium', a model formulated in the 1970s by Stephen Gould and Niles Eldredge.This model describes how species can change very little over longer periods of time, followed by a shorter period of rapid change.To say that the only factors affecting those developments are environmental changes is oversimplifying the model a bit, I think. The period of rapid change could be triggered by anything from changes in the environment to population growth to changes in the structure of the population, and so on.

A scientific model can change if new evidence is found. If the new evidence that has been found contradicts the model or theory then a scientific model or theory can change.
The model comes already setup since the dimension is relatively small.
The view of evolution occurring relatively constantly over a long time frame is called gradualism. This stands in contrast to the view of long periods of stasis punctuated by relatively rapid change, usually caused by environmental change. This is called punctuated equilibrium.A modern view of evolution recognizes that both processes are at work.
