Question

Sharks and dolphins both have fins. These organs are analogous because they perform similar functions but they evolved independently. What does this indicate? There are two correct answers.
1.They indicate convergent evolution.

2.They perform similar functions.

3.They indicate a very close evolutionary relationship.

4.They have similar anatomy.

Answer 1

Answer:

1. They indicate convergent evolution.

2. They indicate a very close evolutionary relationship.

Explanation:

Convergent evolution is when two species have similar traits that may have evolved at different times, or "independently." So that's a correct answer.

Having a close evolutionary relationship would be both evolving to fit a specific environment in a same way. Meaning that the same factor may have forced them to evolve the same.
