You are absolutely correct.Common DNA does not really matter.Commonality just by being a living thing in this universe is commonality enough.BTW This is not the only Universe it is just one of an infinity of Universes.It is now believed that in order for everything to work the way it does there are 11 dimensions the first one existing within millimeters of our own skin.It is also now believed that time travel is possible in both directions and is not prohibited by the laws of science.If this is true and I happen to believe it is then it means that time travel has already happened.In one of these other universes this terrible happening did not occur and politics does not exist either.I think I would like to go there myself.mississippitom
