What is a model describing the rapid evolution that occurs when mutation of a few genes results in a species suddenly changing into a new species?
This process is known as punctuated equilibrium, a hypothesis that suggests evolution occurs in sudden bursts of change followed by periods of stability. It proposes that speciation can occur rapidly after mutations in a few key genes lead to significant changes in an organism's phenotype, resulting in the formation of a new species.

Who proposed mutation theory of evolution?
Hugo de Vries is the one who proposed theory of mutation . He said 'Mutation are discontinuous variations. These are due to changes in chromosomes, genes and DNA and may or may not be inherited.'.
How the gradualism model of evolution differs from the punctuated equilibrium model of evolution?
The gradualism model of evolution suggests that evolution occurs slowly and continuously over long periods of time through accumulation of small, incremental changes. In contrast, the punctuated equilibrium model proposes that evolution occurs in rapid bursts of change followed by long periods of stasis, with new species appearing suddenly in the fossil record.
Which discovery could provide evidence against the theory of evolution?
A discovery that shows species appearing suddenly in the fossil record without any preceding ancestors would provide evidence against the theory of evolution. This would contradict the gradual changes in species predicted by evolution.
Can you doubt evolution?
You can doubt evolution and anything else you want. The better question is if you should doubt evolution, or if you can reasonably doubt evolution in light of science. A lot of aspects concerning evolution are backed by rather sound science. That isn't to say that the theory of evolution explains everything. The earliest textbooks on the topic said that you had to take parts of it by faith. That is no different than believing what religion has to say about it. You do have to ask yourself how to reconcile the laws saying that matter and energy cannot be created nor destroyed with the Big Bang Theory. Since if there was nothing, then you must ask where all the "something" suddenly come from.
Why does a million of invisible constantly changing their location itching and causing sharp pain spots suddenly appear all over your body after physical work?
The sensation you are describing sounds like a reaction to histamine release due to physical exertion. When you exercise, your body releases histamine, a chemical that can cause itching and pain sensations. This reaction is common and usually dissipates as your body recovers from the physical activity.

If genetic mutation almost always leads to sterilization and death then how can evolution be true?
Genetic mutation does not always lead to sterilization as you point out. This however is not the way evolution happens. Evolution occurs mainly through small adaptive changes over a long period of time that are not mutations. Evolution does not happen suddenly.
What function does mutation commonly mess up?
suddenly drastic change in the function of an organ of the body

Why would three fish suddenly start to bully another?
Maturity, wanting of breeding, changing of hierarchy.
Can the battery on a 1999 626 discharge suddenly when changing spark plugs and wires if not disconnected first?
No. There is nothing involved in changing plugs that requires or draws electrical current.

Why is the Cambrian period a key period in the geologic record?
Because it disproves evolution. Lots of fossils suddenly appearing of fully formed animals. Points to the creator God.
