This is bad news for all racists of the world. Anthropologic studies tied with computer simulations show that the most recent common ancestor (MRCA) of all humans could have lived as early as 1500 BCE. The reason for this is that human populations have migrated and interbred significantly throughout the millennia. By estimating how different groups intermingle, the researchers built up a picture of how tightly the world's ancestral lines are linked. What the researchers also stated is that if there were no oceans the MRCA would have lived much more recently. The investigation goes further and stated that the MRCA might have lived in East Asia. The reasoning behind this is that East Asia is close to the Pacific, the Bering Strait and is contiguous with Europe. “Nonetheless, the results show that we are one big family”, the author of the study said. He and his colleagues added: "No matter the languages we speak or the color of our skin, we share ancestors with those who planted rice on the banks of the Yangtze, who first domesticated horses on the steppes of the Ukraine, who hunted giant sloths in the forests of North and South America, and who labored to build the Great Pyramid of Khufu."
I wonder how a racist would interpret this information. Would he or she question the research, its methodology or the statistical analysis? How would someone who ascertains the superiority of his or her race view the world after learning this? How about the ones who claim the “purity” of their genetic background? Most of my readers are not racists; however I am curious with respect to the opinion of a self-proclaimed racist.
I have researched the topic and the estimates for the time when MRCA existed range from 3500 to 15000 years ago. It does not matter. As the authors of the study said, we are all one big family.
