C) small body size
After the environmental change, there was likely a shift towards favoring smaller body sizes in the fish population. This suggests that individuals with smaller bodies were more likely to survive and reproduce in the new environment.
Problem
In a certain population of fish, individuals can have either large, medium, or small bodies.
At some point in time, the fish population experienced a change in its environment. This change led to a shift in the number of individuals with different body sizes in the population.
The table below shows the percentage of fish with large, medium, or small bodies both before, and multiple years after, the environmental change.
Before environmental change After environmental change
