Punctuated equilibrium is a model of a rapid mutation that happens rapidly or over a short period of time. On the other hand the gradualism model states that this change takes place slowly unlike the punctuated equilibrium.
A fossil contained in the tock
A trace fossil provides evidence that an organism existed. Examples would be fossilized footprints or handprints also dung.
A fossil would most likely be found in sedimentary rocks
Depending on the size of the fossil, anything from a micrometre to a metre.

That would be a form of gradualism. Call it "geological gradualism".
Nothing would happen todays time. Fossils are evidence from the past. If the toucan were to become extinct there would be no fossil records of this specific generation of toucan. The fossil record would be the same only you can look back to see what random mutation occurred that was not adventageous causing this species to go extinct.
Under pressure from its rank and file, its strategy of reformist gradualism was being replaced by calls for revolution.
The time frame does change the fossil world wide. The fossil in today's present would be different then it would be years ago.
Fossil records back up evolution by showing the ancestors of extant species. If species didn't evolve, the fossils would be of species currently living, since none of them would have changed. Extant = Currently living Extinct = No longer living

the answer would be the fossil records. they show the "past life" of all the organisms that lived and are now fosssils. -Megan(:
Gradualism was key to the early iterations of evolutionary theory, as proposed by Charles Darwin. Darwin's belief was that evolution was a uniformly gradual process, and that the fossil record would reflect this. Of course, it turned out that evolution is not a uniformly gradual process, but that the rates at which morphologies change can vary enormously, giving rise to punctuated equilibria: long periods of relatively slow change punctuated by short periods of rapid change.It should be noted that although gradualism has been rejected, evolution is still a gradual process, any significant change in morphologies usually taking at least thousands of generations to manifest (although there is no natural law preventing morphological divergence to occur even more rapidly).
