The Two People We're All Related To

  • Published: 24 October 2018

    Due to an odd quirk of genetics and some unique evolutionary circumstances, two humans who lived at different times in the distant past managed to pass on a very small fraction of their genomes to you. And to me. To all of us.

    So, the saying "we're more alike than we are different" has more than 1 meaning.

          There was no quirk. 30,000 yrs ago there was an unknown catastrophe & the human pop. Dropped to 3,000 on entire planet.

              So no matter who we marry, we are all incestual? That’s not fun, but what is fun is that I am some how related to Keanu Reeves and I think that’s beautiful.

                            I believe the mitchondrial dna passed down the past 200,000 years might allow all of us to have some form of telepathic abilities.

                                    Human evolution (all evolution) is getting messier the more it's studied. I'd say complex, but this doesn't convey the right amount of random chaos. Right now trees are showing Homo heidelbergensis as the trunk for sapiens, neanderthals, and denisonans. If that's true all could carry the same Y chromosome lineage despite the interbreeding, but how likely is this when interbreeding and DNA transfer is constantly being discovered across what we define as "species". Genetic drift lineage assumes just one Y chromosome ancestor, but there's reason to doubt that. Multiple Y chromosomes in a messier Homo ancestry would have been highly related, but they wouldn't trace back to a single individual. The loss of this assumption would throw off age calculations.

                                          There is no proof for the Y-chromosome haplogroups leading back to one single ancestor. This is actually not proven and doesn't have near the same empirical data as the mithocondrial Eve, might want to mention this is a theory that basically only exists because of that's how it works with your maternal line. There is very very little proof of (almost) any macro haplogroups on your Y-dna side.

                                          Could also take up how one Australian aboriginal had an MTdna group that ain't related to any other recorded.

A bit is the smallest unit of information. Any chunk of DNA holds many, many bits. If you are going to talk about a scientific concept then at least get the basics right.

It doesn't mean those are the first modern humans it just means the lineages of other humans or the other humans themselves didn't survive. IT could also mean that other Mitochondria DNA was replaced.
