This is the concept of gradualism.
This is the concept of gradualism.
Darwinism
Gradualism is the concept but I would not give it the ranking of scientific theory. It is more a subset of the theory of evolution by natural selection and was first formulated into that theory by Darwin.
yes.
A lot of natural selection occurs very slowly. It took the evolution of the dog from the wolf to take at least 14,000 years. It took singled celled life 3+billion years to evolve into multicellular life.
This is the concept of gradualism.
Darwinism
No, it happens in small leaps. This is called punctuated equilibrium. Gradualism is actually the answer to the question though punctuated equilibrium is also another tempo of evolutionary change.

Evolution through natural selection occurs slowly over millions of years. It has been hypothesized that evolution is the result of positive mutations that occur in a community of organisms that help them survive better. Evolution is essentially descent with modification.
Intermediate species forms, yes. A the taxa level, no. Still, not all taxa evidence is supportive of punctuation and stasis. Punctuated equilibrium is only one explanation of how evolution occurs in some species, not all species. The little shellies evidence gradualist processes very well.
The verb in this sentence is "works." It is the action word that describes what the subject (he) is doing.
She ran slowly, but steadily, and soon finished the race. He wrote steadily for hours.
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.

I think the attribution you are looking for is "Darwins' theory of evolution". He wrote several books hypothesizing his theories, the most pertinent to your question being "Origin of Species". You might also want to look up something called the "kalisto effect"... It is a theory based on a similar principal, but in which, occasionally evolution takes makes a giant step and creates a short lived, but particularly efficient abhoritional species
