Question

Priya says that behaviors cannot be adaptations because they are not inheritable. What is the BEST evidence that some advantageous behaviors may be linked to genes and reinforced through natural selection?

A.
Many deep-sea animals have large eyes that help them see better.

B.
The members of fish populations can have different behaviors.

C.
Most marine plants live only in the sunlight zone of the ocean.

D.
Members of some marine species live in clusters for protection.

Answer 1

The answer is B.

Step-by-step explanation:

The BEST evidence that some advantageous behaviors may be linked to genes and reinforced through natural selection is B. The members of fish populations can have different behaviors. Just like physical traits, behaviors can also be genetically determined and can be passed down through generations. The fish populations that have inherited behaviors that make them more successful in their environments are more likely to survive and reproduce, thereby passing those behaviors to their offspring. As a result, advantageous behaviors can be shaped by natural selection and become more prevalent in a population over time.
