I cannot remember any examples, but so what? Just because some changes are sudden does not mean that all of them are. That is the logic of hasty generalization. In geology there are examples of both. Plate movement is the cause of large scale earth quakes, but not all plate movement results in large scale earthquakes. In fact the norm appears to be small tremors that often go unnoticed. To see earthquakes like the recent on in Turkey and Syria and think that all such motions have to be deadly need to go to Iceland. Iceland has about 500 earthquakes a week. But most go unnoticed. A lot of small changes add up to large ones. The fault in Turkey is a plate border similar to that of the San Andreas fault. There are long times between movements so the movements tend to be large scale and violent. We can see small scale changes occurring in biology constantly, but deniers of science think for some odd reason that those do not count.I've listed dozens of observations in changes in life that are sudden and this is another. If you closely monitor the growth of children you'll see that it is never even. They'll go for long periods with no measurable growth and then short periods where they grow significantly.
Such is the nature of life.
