Gradualism
Gradualism
The model known as gradualism.
Gradualism was key to the early iterations of evolutionary theory, as proposed by Charles Darwin. Darwin's belief was that evolution was a uniformly gradual process, and that the fossil record would reflect this. Of course, it turned out that evolution is not a uniformly gradual process, but that the rates at which morphologies change can vary enormously, giving rise to punctuated equilibria: long periods of relatively slow change punctuated by short periods of rapid change.It should be noted that although gradualism has been rejected, evolution is still a gradual process, any significant change in morphologies usually taking at least thousands of generations to manifest (although there is no natural law preventing morphological divergence to occur even more rapidly).

Gradualism (as opposed to punctuated equilibrium).
Evolution That's wrong. Don't listen to that answer. It's gradualism!!
Gradualism (as opposed to punctuated equilibrium).
Gradualism and catastrophism are key terms in geology. Gradualism is the view that profound changes occurred as the cumulative product of slow but continuous processes, while catastrophism is the idea that the Earth underwent abrupt and violent events.

The answer is: gradualism

This is the gradualism model.

The model known as gradualism.
Gradualism proposes that evolution occurs through a slow and continuous process, with small changes accumulating over time. Punctuated equilibrium, on the other hand, suggests that evolution happens in rapid bursts of change separated by long periods of little to no change. Both theories address the concept of how species evolve over time, but they differ in the pace and patterns of these changes.
