i wonder what percentage of people understand that all living things on earth share a common ancestor.
This might be a really dumb question, but is it possible that any two human beings don't share a common ancestor? Like, do we all link back to a single bacteria or were there multiple "made" at once?
No, all humans share a common ancestor, as does all multicellular life. Google clades for more info.
