The ghost of Stephan Jay Gould says you are completely FOS.
Oh, Brent TFE= too [bleep] easy.
As is your norm, you've misunderstood Gould. When a paleontologist or an evolutionary biologist uses the phrase "sudden alteration" or "sudden speciation," they don't mean "sudden" in terms of a historical time frame, but in a geological time frame, i.e., "sudden" compared to what was believed previously by paleontologists and evolutionary biologists.
The early prevailing theories were that change is a gradual and steady state, without significant pauses in the process, but Gould proposed that, per species, there were long periods of relative stability, punctuated by "sudden" changes here and there, in response to the "sudden" appearance of environmental stressors. Again, "sudden" being relative to geological scales of time, not historical scales of time. To you and me, that's still extremely gradual, on the scale of millions of years for a slight alteration to be observable. In other words, even a "sudden" change on this scale would be not measurable by you even if you were born fifty-thousand years ago, and have been watching carefully till today.
