Darwin proposed that evolution proceeded at a slow and steady pace, a model known as gradualism. but his galápagos finches did not follow this model. what model of evolution did they follow? explain how the two models differ

His finches followed the model of punctuated equilibrium which is when species develop rapidly at isolated events. This is contrary to gradualism because gradualism is when species develop slowly over time. Gradualism and punctuated equilibrium are two methods in which the evolution of a species can happen. A species can develop by only one of these or by both. Experts anticipate that species with a lesser evolution altered classically by punctuated equilibrium and those with an extended evolution established typically by gradualism. Gradualism is assortment and difference that occurs more gradually. Small differences that is appropriate to an organism somewhat improved to its environment are designated for a rare more people with more of the obliging trait endure, and a few more with fewer of the helpful characteristic die. Very gradually, over a long time, the inhabitants’ alterations. Change is slow, continuous, and steady. In punctuated equilibrium, alteration comes in spouts. There is an age of very slight modification and then one or a few huge variations happen, frequently through changes in the genetic factor of a few people. 

The answer is b. hope this !
