Darwinism: it was discovered by Charles Darwin and so named.
evolution
The theory of punctuated equilibrium proposed by Stephen Jay Gould and Niles Eldredge suggests that genetic change can cause species to evolve rapidly in short bursts, with long periods of stability in between, rather than gradually over time. This theory challenges the traditional view of gradualism in evolution.

the theory of evolution
A gradual change in life-forms over time is organic evolution.
Darwin's theory of natural selection is referred to as gradualism because it proposes that evolutionary change happens slowly and gradually over long periods of time, through the accumulation of small, incremental variations in populations. This contrasts with other theories that propose sudden and abrupt changes in species.
Gradualism. This theory proposes that evolution occurs gradually over many generations through small, incremental changes in populations.
The theory of evolution proposes that species can change over time through processes like natural selection, genetic drift, and mutations. These mechanisms drive variation within populations, allowing those individuals with advantageous traits to survive and reproduce, resulting in changes in the species over successive generations.
The theory of evolution, proposed by Charles Darwin, states that changes in species occur gradually over long periods of time through the process of natural selection. This theory suggests that new species arise from the accumulation of small, incremental changes in traits that are advantageous for survival and reproduction.
Charles Darwin changed history with his theory of evolution. His theory of evolution suggested that species undergo small changes over time.
