Isolation of population and impact of climate change creates speciation. It is the method of slow change of one species to another.
Evolution--basically anything that is "change over time" in the terms you are thinking is evolution.
Evolution
Evolution is a slow, slow process which enacts itself over many generations. Species evolve to adapt to environments and to survive, which makes evolution the mechanism through which "survival of the fittest" succeeds as a natural order.
The model known as gradualism.
The short, simple, answer, is survival. The environment is one of the things that drive evolution. When a species is suited to the environment in which it lives it remains relatively stable in it's particular form and exhibits little change.If the environment becomes unstable or is radically changed in some way, such as ever more cooling temperatures, or a depletion in some natural resource, this drives a species to adapt to the new environment through change/evolution. Depending on the speed with which an environment can change, or the severity of the change in the environment, the pace of the evolution can be relatively slow or relatively fast, but in geologic terms, either fast or slow evolutionarily speaking, the change is still slow in human terms. Evolution always takes usually several millennia, and on rare occasions, based on the scope of the environmental changes, it can happen in as little as several centuries, but this is the exception and not the rule.
All life is an example of evolution. It is the slow change of a species.

Evolution
The answer is: gradualism
Slow evolution refers to a gradual process of change in species over long periods of time through natural selection and genetic variation. It often involves small, incremental changes in traits that accumulate over generations, leading to the diversification of species and the development of different characteristics. This slow pace of evolution contrasts with rapid evolutionary changes that can occur in response to sudden environmental shifts or selective pressures.

This is the gradualism model.

No, evolution is not over. Whenever the environment changes, and it is changing all the time, life has to adapt. Even without environmental change, slow, gradual honing of species to their niches would continue, and there is also the matter of genetic drift.
