It is in a few hours. And yeah I will pass. I am not saying humans can be identical to each other but will have a nearly identical genetic code to just about anyone in the world and it does not matter what your 'race' is. There is nothing hard-coded that makes us different from one another in any significant way. There are slight variations but the actual genetics involved in those variations are minimal. Incredibly so.
People are still pretty ignorant about this. Look at my last post. i edited it.
@Medivh, About the European Imperialistic Catholics thing? http://anthropology.net/2008/06/30/the-concept-of-race/
Have fun with all that. Learning is fun!
I have seen and read some of that WIki link you posted, but I am far from convinced. If race is really purely a social construct and has nothing to do with genetics, shouldn't then Brad Pitt and Angelina Jolie be able to have http://www.heavensfamilymedia.org/mini-update/special-reports/africatrip-09/06-07/african-child.jpg (adoption does not count!

) Anyway, I'm no geneticist, so I'll leave it at that.
About the European imperialistic Catholic thing however, both you and the writer of that little article are very wrong.
All the history books that I have read suggest that race was first recognized when the Europeans came over to America and saw the Native Americans.
The definitions that I am referencing are from “http://www.amazon.com/Social-Construction-Difference-Inequality-sixuality/dp/0072997567” with Tracey E. Ore describing race as “a group of people who perceive themselves and are perceived by others as possessing distinctive hereditary traits.” Whereas ethnicity would be “having cultural traits such as language, religion, family customs, and food preferences.”
Obviously the guy hasn't read a lot of history books (or only a whole bunch of books by apologists writing about the slavery system in the early modern Atlantic world).
Somehow every 'historian' who's work this author's read claims that people did not recognize different races (following Ore's definition, which he uses himself) until Europeans came to America. This in an incredibly silly idea. The first definitive instance of someone mentionging race, as being "a group of people who perceive themselves and are perceived by others as possessing distinctive hereditary traits”, that I can think of is in Tacitus' Germania. Tacitus there makes practically the same distinction between race and ethnicity when referring to the Germanic peoples, labelling the Germans as a race and the different tribes, with their own cultures, as being of differing ethnicities (though he does not use that specific word, it is however what he intends). The distincitve hereditary traits he mentions that separate them from Celts and Romans are their blue eyes, red hair, their great height, great strength but lack of endurance and a few other things.
Now whether his description of the Germans is correct (which, in several of his examples, is doubtful by the way, especially in the border areas there probably wouldn't have been any noticebale difference between Celts and Germans, besides perhaps their languages) is completely irrelevant. What is important is that an author in around 98 AD, long before the existence of the Catholic Church (which is not the same as Christianity!) and over 1300 years before Europeans arrived in America, already uses the same definitions of race and ethnicity that you claim are invented by Catholics in the fifteenth century. And this is only the earliest example I can think of for which I have clear proof, but Tacitus definitely wasn't the first. I'm pretty sure that the ancient Greeks thought of the different peoples of the Persian empire as being of different races than their own, for example. So no, you really cannot blame Catholics for that.
