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.
how natural selection help some species to survive and few got extinct
Notincluding human intervention. Natural selection.

How it can change in response to its enviroment
Charles Darwin's theory of evolution primarily focused on how species adapt and evolve through natural selection, but it does not specifically address extinction. However, the principles of natural selection imply that species that cannot adapt to changing environments or compete effectively for resources may become extinct over time. Extinction can be viewed as a natural consequence of evolutionary processes, where less fit species fail to survive and reproduce. Thus, while Darwin's theory doesn't directly explain extinction, it provides a framework for understanding the dynamics that can lead to it.
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.
Yes, it is true.
It shows natural selection by showing how different birds have adapted over time to continue living, and the birds which didn't adapt, went extinct.
