According to science, natural selection chooses the best features for the best survival. When those processes do not occur for some reason, the species does not survive.
Natural selection occurs when a certain environment favors a particular characteristic or trait over another. With this being said, when a species becomes extinct, this means that that species' particular set of characteristics or traits was not the most favorable for them to survive in that certain environment.

When part of a population becomes separated from the rest, a process known as allopatric speciation often begins. This leads to the development of new species over time as the separated populations adapt to their respective environments and accumulate genetic differences.
How it can change in response to its enviroment
Natural selection is the means by which living things are selected to reproduce. It is called natural because it is what happens in what is considered ordinary living conditions. It works by allowing only those creature capable of surviving getting to reproduce. If a creature is incapable of living/surviving in the environment that it finds itself in then it doesn't reproduce and becomes extinct.
