Answer:A trait evolves in anticipation of a future environmental change
Explanation:
A trait is developed to accommodate or adapt to a current environment.
Development of new traits occurs in species so that they can survive the current conditions, they develop traits that are needed to survive at that moment.
A trait may need to change or be altered in the future because the future is unknown , conditions can change and call for adjustment of some traits that have been acquired.
So traits evolves to accommodate the current environment not the future .
