The Graduated model, also known as the phyletic gradualism model, is the model of evolution that is closest to what was originally suggested by Charles Darwin. This model proposes that evolution occurs gradually and continuously over long periods of time through the accumulation of small changes in populations. The punctuated equilibrium model, on the other hand, suggests that evolution occurs in rapid bursts separated by long periods of stasis, and was proposed by Stephen Jay Gould and Niles Eldredge in the 1970s as an alternative to the Graduated model. Therefore, the correct answer is B.
