That depends on what you mean by 'immediate'. Drastic rates of evolution are possible in many species, where mutations are either relatively very common or where the environment results in harsh selection.
But nothing will make one species "immediately" evolve into another in one generation, or even two or ten.
The immediate creation of a new species is not possible, as it usually takes many generations for enough genetic changes to accumulate to create a distinct new species. Evolutionary processes such as genetic mutations, natural selection, genetic drift, and gene flow over long periods of time are typically responsible for the formation of a new species.
One result of the war on the Balkan peninsula was the creation of new independent states such as Bosnia and Herzegovina, Croatia, and Slovenia.
They are involved with the creation of a new copy of an animal (plant). Thus, reproductive organs are involved with the reproduction of the species.
Autotomy is the ability of an animal to voluntarily shed a body part for defense or escape. While autotomy involves regeneration of the lost body part, it is not considered reproduction because it does not involve the creation of new offspring. Reproduction typically refers to the production of new individuals of the same species.
The formation of a new species can result from various mechanisms, including natural selection, genetic drift, and isolation that lead to reproductive barriers between populations, preventing interbreeding. Over time, these factors can accumulate genetic differences and eventually result in distinct species.
Plants can reproduce with other plants of the same species, but some plants can also reproduce with different species through cross-pollination. This can lead to hybridization and the creation of new plant varieties.
The creation of a new species is called speciation. This process occurs when populations of a species become reproductively isolated and diverge over time, leading to the formation of distinct species.
In the process of natural selection, adaptation leads to the creation of new species.

Extinction
Speciation is the best term to describe a new species developing from an existing one.
reproductive isolation
a new species might form when a group of individuals remains sparated from the rest of its species long enough to accumulate different traits
Saltationism. Called the " hopeful monster " theory. Long refuted. Mutation is the grist to the mill of natural selection but in and of itself will not result in new species.
