I read someone write "If you go back far enough, pretty much everyone is related to everyone." I wonder if all humans are cousins of all other humans. Perhaps the answer would depend on whether or not all humans alive today are directly descended from the first humans to evolve from lower primates. Let's use as an example the first human to evolve from lower primates. I will call the first human to evolve from lower primates Jane. And then I will call the lower primate closest to a human Joe. Joe was a lower primate closer to a human genetically than any lower primate that ever lived. Could Joe impregnate Jane if they had sex with each other? If not, how did the first two humans come about? Would the first two humans to have human offspring have to be two lower primates of opposite sex who had the same identical genetic mutations? Are all humans related genetically to all other humans?
