2. Your friend has just returned from a deep sea mission and claims to have found a new single-celled life form. He believes this new life form may not have descended from the common ancestor that all types of life on Earth share. However, he’s never taken Cell Biology, so he asks you determine whether his claim is true. In order to verify or dispute your friend’s claim, you realize that you must first make a list of characteristics common to all prokaryotes and eukaryotes, so that you can check whether this new life form is different in some fundamental characteristic from all other types of life on Earth. So you generate a list of traits shared by all prokaryotes and eukaryotes. What would you place on that list?
