In the section "Investigating Life: Size Matters in Fishing Frenzy", historically fishermen kept larger fish and left smaller juvenile fish. Over time the average size of the fish would

A. increase by natural selection.
B. decrease by genetic drift.
C. decrease by natural selection.
D. increase by genetic drift.
E. remain unchanged.

Answer 1

The average size of the fish would decrease by natural selection due to selective fishing of larger fish.

Step-by-step explanation:

The section you mentioned is about the size of fish in fishing frenzy. Historically, fishermen would keep larger fish and release smaller juvenile fish. Over time, this selective fishing would have an effect on the average size of the fish population. In this case, the average size of the fish would decrease by natural selection.
