The theory you are referring to is often known as gradualism. It posits that evolution proceeds at a constant and slow rate over long periods of time, leading to gradual changes in species. This contrasts with the theory of punctuated equilibrium, which suggests that evolution can occur rapidly in short bursts followed by long periods of stasis.
The hypothesis that evolution occurred slowly but steadily is called gradualism. This theory suggests that small, incremental changes accumulated over long periods of time to result in the diversity of life we see today.
The theory that proposes evolution occurs steadily in tiny changes over long periods of time is gradualism. This idea suggests that species evolve slowly and continuously through small, incremental changes rather than through sudden, dramatic shifts.
The theory of punctuated equilibrium suggests that evolution occurs rapidly in short bursts followed by long periods of stability. This contrasts with gradualism, which proposes that evolution happens slowly and steadily over time. Punctuated equilibrium is supported by the fossil record, where evidence of rapid changes in species can be observed.
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.
Gradualism is the theory that evolutionary change occurs slowly and steadily over time through small, incremental changes in populations. It suggests that large evolutionary transitions are the result of many small changes accumulating over long periods of time. This contrasts with the idea of punctuated equilibrium, which proposes that evolution happens rapidly in short bursts followed by long periods of stasis.

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.
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.
The theory of gradualism suggests that change occurs slowly and steadily over time.
Gradualism. This theory proposes that evolution occurs gradually over many generations through small, incremental changes in populations.
Punctuated equilibrium. This theory suggests that species experience long periods of little change (stasis) interspersed with sudden bursts of rapid evolution due to environmental changes or other factors. This contrasts with gradualism, which proposes that evolution occurs steadily over time.
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
