A researcher makes the claim:

"Algae and fish share a common ancestor"

Which of the following statements provide valid evidence and sound reasoning to support this claim?

Algae and fish both live in the ocean. The place where organisms live can be used as evidence that they share a common ancestor.
Algae and fish are composed of matter. Being made of matter can be used as evidence that two organisms share a common ancestor.
Fish are able to eat algae. A predator-prey relationship can be used to determine whether two organisms share a common ancestor.
Fish cells and algae both have DNA. Whether an organism has DNA can be used as evidence that they share a common ancestor.
