Scientists study life processes of organisms to try to find relationships that can help provide insight into the history of life on Earth.

Which of the following accurately describes the relationship between cyanobacteria and halophiles?

1) Cyanobacteria are photosynthetic, which suggests they existed before halophiles.

2) Halophiles can survive in extreme conditions, which suggests they are more evolved than cyanobacteria.

3) They both undergo cellular respiration, which suggests they share a common ancestor.

4) They reproduce asexually, which suggests they evolved independently of each other.
