What you are talking about “sudden” have nothing to do with Evolution.
You need to learn and understand the scopes of Evolution, which isn’t about changes of individuals or changes in individual family (parent-offspring) of few generations.
Even among bacteria, speciation don’t occur in a few generations.
A single day for bacteria could result anywhere from 50 generations to 147 generations.
Species of bacteria that develop immunity or strong resistance to antibiotics, may take as long as 4 to 10 months.
Even if we were talking about the shortest amount of time, like 4 months (about 120 days) for instance, that over 17,000 generations...that’s not “sudden”. And if were talking about a year or 365 days, that would be over 53,000 generations.
These are estimates of time and the numbers of generations, are based on the record of observing (in the lab) a single bacteria reproducing at 9.8 minutes old. Of course, not all bacteria would reproduce after being alive for 9.8 minutes, the time would of course vary widely, depending on the species and the environment the bacteria are found.
The point, even with bacteria, speciation isn’t sudden like your absurd 3 generation nonsense.
Your example implied human. Speciation most certainly don’t occur in 3 generations among humans. What you are talking about have nothing to do with Evolution.
You keep making outrageous claims that have no evidence basis, because you clearly don’t even understand basic biology, let alone evolution.
All you are doing is making pseudoscience claims.
