Change in their environment is expected to create sustained changes for optimum adaptation.

Explanation:

Climates and ecologies change over time due to geologic, solar and biological factors. A "natural" change to optimize living conditions and survival means that as those factors change, the more "successful" changes in a community will be propagated. Eventually that will be evident as a change in the community over time.
