An example of very rapid speciation could be the process of polyploidy, which is often observed in plants, but also known to occur in animals. This is the uncharacteristic (at least in that particular species) duplication of all chromosomes in offspring. Occasionally, such a whole-genome duplication can cause an inability to interbreed with organisms from the parental stock, meaning that speciation has occurred. This form of speciation would be almost impossible to occur in species of sexually reproducing animals, unless the same whole-genome duplication occurred more frequently, or the organism in question were able to self-fertilize (some hermaphrodite organisms may be able to do so).
Of course any set of mutations that significantly alters the physiology of offspring without inhibiting its ability to reproduce could be categorized in the same way.
The mutation of the virus made the vaccines useless.Other than evolution, species can also change through mutation.By triggering the mutation of the genes, we created a super soldier.
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.
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.'.
Pseudogenes are non-functional copies of genes that have accumulated mutations over time. By comparing pseudogenes across different species, scientists can study genetic changes that have occurred during evolution. Pseudogenes provide valuable insights into evolutionary processes and relationships between species.
Nowadays, it's called a "birth defect".
The mutation theory is basically stating that mutation is one of the major factors that cause evolution. The mutation has to be a beneficial mutation, meaning that it has to help the survival of the organism that got the mutation. The mutation causes knew genes and diversity which can spread quickly throughout a population and eventually change the frequency of alleles (causes mutation) Remember the mutation has to be beneficial to the survival of the organism.
Punctuated equilibrium
If a particular mutation occurs in nature and proves to be beneficial, it can change the entire species to begin to have the same mutation and thus the same good trait. A creature with a mutation that say, gives it a longer tail (and chicks dig a long tail) than he will mate and that mutation will allow his genes to pass on.

When a mutation is on the operator a gene can die which leads to an evolution of the entire genetic makeup. Also when lactose is absent and the genes should be switched off.
Evolution
Due to genes and mutations, organisms show variation within a species. Changes in the environment can put a selective pressure on the species - certain mutations may be more beneficial, therefore more individuals with that mutation will exist, as they survive and breed. This process is called Natural Selection.
