    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?

      There is a genetic Adam and Eve. However, I don’t think they existed at the same time. These were humans, not just apes/mammals/animals/bacteria. We are all distantly related.

      We are also more related to mushrooms than trees are to mushrooms.

        Yeah, it’s hard to pin down when these common ancestors lived precisely, especially given that as portions of our genome go extinct, the common ancestor will change.

        But Y-chromosomal Adam is estimated to have lived around 200,000 years ago, while estimates for when Mitochondrial Eve lived are a bit more recent, around 150,000 years ago.

            According to an unverified internet search, the average age of childbirth for women throughout history is 23.2 years, and for men it is 30.7.

            So, statistically, your great^6463 grandmother is the same as mine. Same goes for our great^6512 grandfather.

                They were freaks. They didn’t have as many generations of separation so they were definitely fucking their cousin at best.

      A quarter of us trace back to one mongol, fairly certain there’s going to be a point we all tie together to the same ape eating magic mushrooms in what would become Africa. Long ass time ago though

      No, all humans share a common ancestor, as does all multicellular life. Google clades for more info.

      With how funky micro organisms are with sharing DNA I’m not sure it matters. I’ve heard it likened to the genetic tree turning into a bush instead whare it’s a big mes of sharing of DNA across species.
