I don't know why you are so caught up with this mitonchondrial DNA stuff. It is no secret that all people on this Earth originally came from Africa (which does not mean that all people were Negroid but were probably darker skinned). If you go by this, then yes, all the people of the Earth are basically "Africans" for that is our origin.
By this logic, all the "Africans" were also shrews and mice at one time, and if you go back even firther, we were all fish...and before that, Amino Acids swimming in the Ocean.

Your misleading statement about Chinese natives being black is very twisted in that in completely misconstrues the actual facts. While you are trying to create this equation in which the use of the mitochondrial DNA showing all human races having an African ancestry, you believe in the undeniable truth that that same equation means that all people are "Black". That is indeed very twisted.

The correct interpretation would be
1)Yes. all people are descended frmo early human colonists who originated in Africa
2)Mitochondrial DNA shows that all humans had a common origin, probably akin to today's African/Negroid race

With this in mind, we evolve away from this common origin to the issue of race, which is the essence of our discussion. If all people migrated from Africa and all people are black in your eyes, then the mongoloid Chinese are black too, using your logic. Fact is, after thousans of years of evolution, isolation, mutation and so forth, separate races have evolved from the original Homo Sapiens that migrated out of Africa. As a result, several races have evolved, including the Australoid which at one point occipied southern Asia as far as the island of Taiwan in China. These people are not Negro/African, they are AUSTRALOID.

Now let's hear your argument that all people are black because mitochondrial DNA shows we were all Africans 130 000 years ago, a few more times just to make this forum really boring and sleepy.
