Question

which statement best supports the fact that natural selection occurs in the marine environment?
o few marine organisms survive when the ocean environment is unstable.
o genetic mutations occur more frequently every time the ocean environment changes.
o advantageous traits become more common in each subsequent generation.
o the fossil record provides a sample of every marine organism that has ever lived.

Explanation:

Natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation. In the marine environment, this is shown by advantageous traits becoming more common over generations.

Answer:

Advantageous traits become more common in each subsequent generation.
