Charles Darwin and he was rather insistent about the process of evolution being gradual and incremental. He and Thomas Huxley argued about this point often. Today we know that evolution has different speeds depending on organism and environment, but there is no " hopeful monster " jump in evolutionary processes.
Charles Lyell, a geologist, proposed the idea of gradualism in evolution. He believed that geological processes operated at a slow and steady pace over long periods of time, influencing the gradual change in species over time. This concept influenced Charles Darwin's theory of evolution by natural selection.
The theory of evolution by natural selection. Called gradualism.
Evolution That's wrong. Don't listen to that answer. It's gradualism!!
This is the gradualism model.

Gradualism (as opposed to punctuated equilibrium).
Punctuated equilibrium is commonly contrasted against phyletic gradualism, the belief that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis). In this view, evolution is seen as generally smooth and continuous.
Darwin's classic theory of evolution assumed that evolution is a slow, contunuous process, by which new species evolve and emerge. This is referred to at times as "organic evolution" and the "synthetic theory of evolution", or just the Darwinian theory of evolution. A newer theory, proposed originally by Niles Eldridge and Stephen Jay Gould is known as "punctuated equilibria", a model in which the evloution of new species occurs only periodically, in relatively rapid spurts. See "Time Frames the Rethinking of Darwinian Evolution and the Theory of Punctuated Equilibraia, Simon & Schuster, 1985"AnswerThe slow, constant process has also been called "gradualism."
Gradualism.
Gradualism (as opposed to punctuated equilibrium).
When evolution occurs at a slow steady pace, the rate is defined as gradualism. This theory suggests that species evolve slowly over time through accumulating small changes.
