Gradualism and catastrophism are two contrasting theories in geology and evolutionary Biology. Gradualism posits that changes in the Earth's geology and species occur slowly and steadily over long periods, emphasizing the role of incremental processes. In contrast, catastrophism argues that significant changes result from sudden, short-lived, and often violent events, such as natural disasters. While gradualism focuses on continuous evolution and change, catastrophism highlights the impact of rare, dramatic events on the Earth's history and life forms.
Probably gradualism as they have not seemed to change much and have not split to give rise to new species. Stabilizing selection keep this organism evolving slowly.
The theory of evolution by natural selection. Called gradualism.
I think you mean the concept of gradualism and the man is Charles Lyell, whose geological concept proceeded Darwin's biological concept and also gave Darwin his ideas on ages of the earth and gradual processes over time. I can think of not other geologist that was a confidant of Darwin, though Adam Sedgewick, a geologist, was am early teacher of Darwin. He was a catastrophist though.
Charles Darwin is best known for his work on the theory of evolution through natural selection. His book, "On the Origin of Species," published in 1859, outlines this theory and had a significant impact on the scientific community, sparking widespread debate and discussion. Darwin's theory challenged traditional religious and scientific beliefs about the origins of species and laid the foundation for modern evolutionary biology.

Gradualism.
Product creation can proceed via gradualism.
Yes, determining how quickly the species evolved: gradualism or punctuated equilibria.
Under pressure from its rank and file, its strategy of reformist gradualism was being replaced by calls for revolution.
That would be a form of gradualism. Call it "geological gradualism".
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.
Catastrophism- is the idea that past natural disasters like floods and volcanic eruptions, shaped landforms, and caused species to become extinct in the process. And Gradualism- is the idea that landforms were shaped by very slow changes over a long period of time, and not by natural disasters.
Species evolve gradually.

i think its better than using militant activism or nonviolent confrontation. in the end, results will be made through legal gradualism
Gradualism is the policy of gradual reform rather than sudden change or revolution; in biology, the theory that evolution occurs slowly but steadily rather than abruptly.
