The ordering of human variety by color-labeled "race" is a primitive construct that is useful only to authoritarian ideologues. In actuality, our genetic diversity is much too varied and interesting to lend itself easily to coarse political manipulation. For example, the following graphic illustrates the population frequency of the Gallic haplogroup, which, historically speaking, is humankind's driving haplogroup. Ocean access provided the advantage that they eventually used to colonize the undiscovered world.
What makes all of us human, aside from reproductive compatibility, is that we are mentally compatible. Excepting cognitive dysfunction, all of us are, by nature, capable of knowing the same things. As the world's standard of living improves and technology makes the connections possible, people will have more opportunities to express themselves genetically in beautiful new ways. Our variety truly is a blessing.
By the way, for most words and names with a double "L," it is a mark of Gallic origin. It represents the "Pillars of Hercules," the original name of the gateway between the Mediterranean Sea and the Atlantic Ocean. The Twin Towers of the original World Trade Center were also a symbol of the Pillars, before monomania turned them into sacrificial pyres and replaced them with the "Freedom Tower" pyramid.
