In evolution, which molecule - cytochrome C or hemoglobine - is more accurate to determine when two species have close ancestors, and why?
Alternatively, please provide a molecule that is even more accurate when you want to establish a phylogenetic tree tree.

Thank you very much!

In my opinion, it must be cytochrome c which can serve as a molecular link to compare species.

Thank you for your answer! Could you please provide a brief motivation for that?
