The population that evolved at 25 C because it is most adapted to the 25 degree environment. This means that it is more likely to survive to reproduce in this environment.
A) The population evolved at 25°C have the highest fitness at 25°C.
Populations that evolve at a certain temperature are expected to have the highest fitness at that temperature because they have had time to accumulate adaptations that optimize their performance at that specific temperature.
The population that has the highest fitness at 25°C is most likely the one evolved at 25°C itself, as it would be specifically adapted to thrive in those conditions. The other populations evolved at higher temperatures may not be as fit in the cooler environment of 25°C. Therefore, the answer is option A: The population evolved at 25°C.
