We could simplify it and say we all came from Earth but then there are other theories where the earth was seeded by aliens and hence the reason for the evolutionary explosion. But then we couldn't call them aliens because we are of the same root, but then again we don't know where "they" came from. But we do know that one way or the other we all come from the same root and share the same genetic code.
Perhaps we could define it by lifestyle choices, ie this person enjoys a culturally Fijian or American or Indian etc life style no matter what their appearance may indicate they should be. Then we get into... Well the name is already taken, does that mean anyone with the name of George, Bob, Jennifer or Barbara has to give it up because it is already taken.
OR does it all come down to compartmentalizing the whole human race so we can create divisions, then we can hate a whole and entire group of people rather than the few people of that group who have wronged us or that we don't understand. Now that we have these wonderful compartments, we can even go to war over it, and have coups, commit genocide and all kinds of fun things.
OR do we lift the passage out of Shakesphere that a rose is a rose by any other name and a human is a human by any other name and leave it at that because at the end of the day we are all sharing one planet at the moment.
We as humans are supposed to the intelligent ones yet I have never met a Dog who decided he didn't like another dog because he was a collie and this one was a mongrel or a German Shephard or an English Spaniel, American Bloodhound, German shephard, Scottish Terries or an Irish Setter. Don't you love the fact that as humans we have even given dogs territorial compartments by stating their country of origin. The real irony if you were to put most humans under the same scrunity we do for dogs, most of us would be mongrels and the dogs could care less if they are an Austrailian heeler or a mongrel. The poor dumb animals, don't have a clue about what they are missing by having a compartment. My goodness the amount of dog fights they are missing out on is astonishing.
Well that was a fun little bit of free association and the only answer I really like is the Dogs point of view.
